The suspend button in Lubuntu 22.04 desktop asks for confirmation. I'm going to find that really annoying after a while.
My pc is running Lubuntu 20.04.
I am trying to ssh to a raspberry pi 4 running Ubuntu Server 22.04.
I have followed the setup instructions but see the following:

I added some options to my ~/.ssh/config as recommended by various posts (to no avail). It is:

I use this stuff about once every year, when I get a new Pi (each year making extensive notes on what I did), but every year it fails in different ways. Any solutions would be very welcome.
This printer will leave me with PTSD ! I cannot count the number of hours I have spent trying to get it to work.
I did have it working. We moved house, and now have a Plume Mesh network. I kept the same network SSID and passphrase as our old house, and everything connects except the HP printer.
I decided I have to set it up from scratch. On printer menus I did service | restore defaults. Then I connected by USB and ran sudo hp-setup -i. I can print from USB, but the printer needs to be in another room. At no point in the setup have I been asked for an SSID or passphrase. The printer is not connecting to the network (which is not surprising, given it does not know the name). I have no idea how I can provide the printer with the SSID.
Any help would be greatly appreciated.
I am using Lubuntu 20.04. The printer is HP LaserJet M201dw.
I use Lubuntu 20.04, which boots from an SSD.
Today I allowed the system to do upgrades, and subsequently got an error message saying that update-initramfs failed. I googled the error message and found this link which suggested the problem could be resolved by freeing some space on /boot and reinstalling a package. I think I made a mistake trying to do both fixes in one procedure.
I did:
sudo apt remove initramfs-tools
sudo apt-get auto-remove
sudo apt-get clean
sudo apt install initramfs-tools
sudo apt-get update
Everything appeared to be fixed until I rebooted the machine. The machine could not reboot automatically, but I entered the boot menu and picked an older kernel. That worked. Inspecting the broken and working boot commands, I believe that I am no longer booting off the SSD (I could also be wrong).
The broken boot option (which used to work) is:
menuentry 'Ubuntu, with Linux 5.4.0-86-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-5.4.0-86-generic-advanced-f81f27eb-c1f2-467c-a62b-fdd60b4f0592' {

fi
echo 'Loading Linux 5.4.0-86-generic ...'
linux /vmlinuz-5.4.0-86-generic root=/dev/nvme0n1p3 ro quiet splash $vt_handoff
}
... and the working option is:
menuentry 'Ubuntu, with Linux 5.4.0-84-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-5.4.0-84-generic-advanced-f81f27eb-c1f2-467c-a62b-fdd60b4f0592' {

echo 'Loading initial ramdisk ...'
initrd /initrd.img-5.4.0-84-generic
}
Is there any way I can repair the damage and get Lubuntu back to booting from the SSD ? I now think that the autoremove operation may have destroyed some vital information on the SSD.
The broken boot option produces this output before crashing:
If I use the working boot option, I now get the following response from df (/boot appears to be on the SSD, so looks like my idea that this option was booting via the hard drive is probably wrong).
df -h

I am using Lubuntu 20.04 on a Raspberry Pi 3B.
I am trying to use gtts-cli (text to speech program) to generate audio directly by:
gtts-cli "Almost no modern computer function works properly" | mpg321 -
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2, and 3.

tcgetattr(): Inappropriate ioctl for device

Sometimes it works, and sometimes it doesn't. When it does not work, I hear either a click, a grating sound, or a grating sound followed by the last part of the audio. It makes me think that sometimes mpg321 misses the first part of the audio, or corrupt it in some way. Even when it reproduces all the audio correctly, there is a SEGMENTATION FAULT.
I did some investigation. Firstly, to eliminate gtts-cli as the source of the problem, I recorded mp3 output from it and sent that to mpg321. e.g
gtts-cli "It is enough to drive you mad!" -o test.mp3
cat test.mp3 | mpg321 -

I get the same effect. Sometimes it works and sometimes it misses all, or the start of the audio. There is also always a segmentation fault.
I checked if the problem is due to feeding input to mpg321 from stdin, by using the file directly:

MPEG 2.0 layer III, 32 kbit/s, 24000 Hz mono
That still misses some audio at the start, but does NOT give a segmentation fault.
My audio goes to Respeaker USB output. To eliminate the possibility of the problem being in the driver or audio production downstream of mpg321, I tried:
aplay temp.wav
That plays perfectly and consistently every time.
I then installed and tried mpg123 (instead of mpg321). The results were similar, but I think slightly worse than mpg321.
I tried re-installing mpg321 - no change.
What is wrong, and more importantly how can I fix it?
Why does the 'Import Key File' button in Lubuntu 20.04 Software Sources | Authentication dialog not do anything?
I downloaded a key file for Geogebra's repository. I believe that when I click Preferences | Software Sources | Authentication | Add Key File, I should get a file dialog which lets me choose the key file. However nothing happens when I press the button.
I have never used this functionality before, so maybe I am doing something wrong. The manual glosses over the issue, which makes me very suspicious though.
I am using Lubuntu 20.04.
I love the simplicity of Lubuntu, but I decided I wanted a more powerful file manager.
I installed Dolphin and, although I was happy with lxterminal, I had to install konsole in order to get the advantages of terminal integration in dolphin (I tried for a while to get dolphin to use lxterminal, but that wasn't happening for me !).
Now I would like to get Lubuntu to use konsole everywhere, instead of pcmanfm, so I can get rid of it.
I used Preferences | Default applications for LXSession to change Launching Applications | File Manager to dolphin, and rebooted. That caused me to lose my desktop wallpaper and icons. It does not cause my toolbar icon to launch dolphin. Gratefully my desktop came back when I restored pcmanfm.
I discovered that simply changing the command line in pcmanfm.desktop allows the lubuntu menu and toolbar to use dolphin, however the keyboard shortcut ctrl-alt-d still starts pcmanfm.
So, is there a way to replace pcmanfm more thoroughly (and not lose the desktop), or to get dolphin to use pcmanfm ?
My Lubuntu system has recently started complaining that it cannot update software and is offering a Partial Upgrade - which I understand is bad news.
I suspect it is related to my Tensorflow installation (most of my problems are, and I fear changing it in any way !).
nvcc --version reports release 10.1, V10.1.243
nvidia-smi reports Driver Version: 440.64.00 CUDA Version: 10.2
cuDNN is version 7.6
Tensorflow is version 1.14.0
It appears that the update wants to remove the cuda and nvidia driver packages (I have appended the output from dist-upgrade). Please can someone explain what the root of the problem is here, and what I can do to move on (hopefully without totally destroying my working tensorflow installation).

Most people are looking for natural sounding TTS. I am looking for something that has personality for an animatronic creature. It could be robotic or gruff or babyish, but it should be amusing.
I am using Lubuntu 18.04.
Network connections shows 2 wired connections, and both have been used within the last 15 minutes, even though I am connected to Wifi. Please can you explain why, and if this is normal.
I am asking this question in the broader context of trying to find out why my Wifi keeps dropping randomly. There are several unresolved bug reports describing this behaviour, but nobody has solved the problem. Could these wired connections have anything to do with the wifi drops ?
I thought this would be trivial, but after two hours of googling and experimenting still nothing works.
I want to use the ROS+Kinetic-lxde o/s sd image for the Raspberry Pi. As far as I can tell this is Lubuntu. Unfortunately the keyboard layout in the image does not match my keyboard, so I need to change it.
So far I have tried localectl from the command line. That does not do anything. I tried localectl list-keymaps and that says it can't find any console keymaps.
I added the 'Keyboard Layout Handler' applet to the task bar and set the keyboard through that. My changes were lost when I rebooted.
I tried sudo dpkg-reconfigure keyboard-configuration. That let me set up the keyboard, but again the changes were lost after a reboot.
I tried editing the file /etc/default/keyboard, but that already had the correct settings and they are doing no good.
So, how can I permanently set the keyboard type ? It seems crazy that it can't be done easily.
I have (had) Lubuntu 16.04 installed on an SSD. I tried Lubuntu 18.04 from a pendrive, and then decided to install it alongside 16.04, on an internal HDD, to allow further testing.
I selected 'other' as installation type.
I created a new partition table for /dev/sda (the HDD) as follows:
- swap 40gb
- / ext4 30 gb
- /home ext4 rest of HDD (~3.5 tb)
I asked for efi on sda (the HDD), believing this would ensure the OS installed on sda. I was a bit worried about this because there is also efi on the SSD and I was not sure if I should use that instead.
The system warned that it would nuke drives, but it only listed partitions on sda. The system now boots directly into 18.04 on the HDD. My old filesystem on the SSD is still there - I can see the drive in the 'places' view of PCManFM and the files and directories are still intact. I also see an option to boot into 16.04 on the boot menu, and this starts to boot something, but it remains in a loop printing 'Lubuntu wait dots'.
Is there any way I can restore booting into the SSD ?
Edits requested by Tudor
I tried ESC whilst booting '16.04 (on /dev/mapper/lubuntu--vg-root)', offered by Grub menu. At first this did not work, but I later discovered pressing ESC earlier put the machine in 'emergency mode'. After a while it produced some output:
device [8086:6f07] error status/mask=00000080/00002000
Bad DLLP
PCIe Bus Error: severity=corrected, type=Data Link Layer, id=0013(Receiver ID)
This was repeated.
I looked at the code behind the options on the GRUB menu. It is pretty lengthy, but I got the impression that they are all trying to boot something off sda.
I went into the BIOS to see what is offered. I was surprised to see that all the boot options are actually on the SSD:
- ubuntu (Samsung SSD 960 Pro)
- ubuntu (Samsung SSD 960 Pro)
- UEFI OS (Samsung SSD 960 Pro)
I booted 18.04 and used the disks tool to see which partitions exist:
- 512 Gb disk Samsung SSD 960 Pro 512GB
- 4.0 TB Hard Disk Toshiba HDWE140
- 477 GB Block Device /dev/lubuntu-vg/root
- 34 GB Block Device /dev/lubuntu-vg/swap_1
I looked at the partitions on the SSD and HDD in more detail:
SSD
Filesystem Partition 1 537 MB FAT /dev/nvme0n1p1 Partition Type: EFI System mounted: /boot/efi Filesystem Partition 2 512 MB Ext2 /dev/nvme0n1p2 Partition Type: Linux Filesystem not mounted Partition 3 511 GB LVM2 PV /dev/nvme0n1p3
Toshiba HDWE140
Swap Partition 1 40 GB Filesystem Partition2 30 GB Ext 4 Partition Type: Linux Filesystem mounted: Filesystem Root Filesystem Partition3 3.9 TB Ext4 Partition Type: Linux Filesystem mounted: /home
So it seems like the efi partition, that I requested on sda was never made or is not being used. The efi on the SSD is being used, but it seems to have forgotten how to boot the OS on the SSD, although this seems to be otherwise intact.
I forgot to mention before that when I installed 18.04, from the USB installer, it said no OS was detected on the system. This was worrying and I think is probably the cause of the whole problem - the installer never detected 16.04 on the SSD.
I bought a Maozua 5mp USB microscope off Amazon (after checking in the reviews that it worked on Linux). Sadly when I connected it on Lubuntu 16.04 it does not work in guvcview or cheese.
I did some investigation. I show the relevant parts below:
ls /dev | grep video
video0
video1
The microscope is on video1 and a logitech webcam on video0. The webcam works when the microscope is not connected, but guvcview and cheese cannot retrieve video from it when the microscope is connected:

I googled 'microdia' and '0c45:6366' and found a lot of people have struggled with this microscope. Some believe they got it working, but the solutions are spread across long threads stream-of-consciouness-wise and I have not pieced together anything that works. I noted that most of the threads are dated 2008-2009. It makes me wonder whether a working driver became available after that period - but I can't find it !
Any help will be much appreciated.
The following command gives an error message:
gst-launch-1.0 -m pulsesrc ! audioconvert ! audiorate ! audioresample ! deepspeech silence-threshold=0.3 silence-length=20 ! fakesink
WARNING: erroneous pipeline: no element "pulsesrc"
I have installed gstreamer1.0-pulseaudio, pulseaudio, gstreamer1.0-plugins-good. The documentation I found says pulsesrc is in gst-plugins-good, but there is no such package in the xenial repository.
One moment my system was fine. I tried to use Skype and could not get microphone to work. I tried starting pulseaudio volume control. It would not start. After reboots and a lot of messing about I removed and reinstalled pulseaudio. Then when I rebooted there was no desktop. A right click gave me options including terminal and web-browser (I think this is openbox). I tried 'startlxde' from terminal and was told it was not installed. I did:
sudo apt-get install --reinstall lxdm lubuntu-desktop
now if I type startlxde in a terminal I get a desktop, albeit completely unlike my old one. However it does not start automatically. How can I fix this ?
Also the microphone now works fine, but there is no output sound. Should I just salvage any personal work and start to install everything from scratch ?
I am using Lubuntu 16.04. I have analogue speakers that take their power from a USB socket. I'd like them to turn off when I power down the pc and suspend it. I thought that would be pretty easy, but I have spent a lot of time googling and still do not have a solution.
My best bet seems to be uhubctl as this appears to run on my hardware (the author warns that not all hubcontrollers support the functionality). I believe this because I have successfully turned off the USB keyboard.
So now I need to know what to specify to turn off power on the USB socket for the speakers. This is bound to take some guesswork since they are not real USB devices and will not show in lsusb. Looking at the back panel and the motherboard manual, I see that the group of four sockets where the speakers are plugged in are described as USB 2.0 ports 7-10. My mouse and webcam are plugged into the same group of sockets.
Running uhubctl with no arguments gives:

That is not too helpful. My keyboard shows up, but all my other USB devices - mouse, Seagate HDD, webcam - are not mentioned.
I tried various commands:
uhubctl -a off -p 2 -l 3-9 #Turns off keyboard as expected
uhubctl -a off -p 2 -l 4-5 #ALSO turns off keyboard. Why ?
uhubctl -a off -p 12345678 -l 2-1 #Does not turn anything off
uhubctl -a off -p 123456 -l 1-1 #Does not turn anything off
uhubctl -a off -p 134 -l 4-5 #Does not turn anything off.
So I can turn off the keyboard. No other USB device is listed (although they are there) and they cannot be turned off.
I have no idea what the hub names represent i.e. 2-1, 1-1, 4-5, 3-9. Nor does there appear to be any way to infer the hub names from lsusb.
lsusb gives:

I can see there is some relationship between the hub names and the bus/port numbers but I can't come up with a rule.
I noticed from lsusb that the USB 2.0 devices seem to use an Intel controller whereas the USB 3.0 and 2.1 devices seem to use an ASUS controller. I wondered whether the Intel chips might not support power control so I tried the speakers in the USB 2.1 socket which I can turn off when it is attached to the keyboard. No luck.
Does anybody have any idea why uhubctrl behaves as it does ?
Maybe uhubctl is a red herring and is not going to work. I know there are other ways to switch power in Ubuntu but they seem to depend on being able to determine the directory which represents the usb socket. This I have no idea how to do.
I installed simon (speech recognition tool) from Synaptic. I am using Lubuntu Xenial. I have wasted a night trying to get it to work and still have no clue what it wants me to do.
The first time I started simon it tried to lead me through the configuration. I have never been able to get back to that. Now when I start it, I am thrown straight in to its main dialog.
I discovered I have to install libqt4-sql-sqlite. Did that.
I try setting up from the main dialog: settings | configure simon... | speech model. I would like to set a speech model. I click open model | download and get a bunch of desktop themes displayed. I type EN/VF in the search bar. I see something that looks like a voice model [EN/VF/JHTK] Voxforge and click install, close. I still don't get any options apart from 'Do not use a voice model'. As far as I can tell no voice model is loaded.
I managed to download a scenario [EN/H4W] Window Management that appears to do something (it appears in the list !).
Activating simon shows it is hearing me, but no recognition reported and no useful activity of any nature.
Is there any 'Hello world' type setup for this. I cannot find any clear explanation of what needs to be done. As always I can find A LOT of information that appears to be for other versions that look nothing like what I see (I tried 'help' but that just says it can't find the KDE help centre - obviously on Lunbuntu).
I am sure people have put a lot of work into this project, but it is wasted if it is completely impossible to use.
After I upgraded from Lubuntu 14.04 to 16.04 I have had problems using my hotmail account. It has worked sometimes, but now it is almost impossible to connect. The browser reports 'server not found'.
I googled extensively and found a whole load of issues relating to Firefox - resolved by clearing cookies, changing dns and ipv6 config etc, etc...
After diabling DNS prefetch and ipv6 in Firefox configuration, hotmail started working immediately. Hooray ! Only to pack in again after a few days.
I gave up on Firefox and installed Chrome. No change ! I tried another machine with Lubuntu 16.04 - exactly the same, I cannot open hotmail.
Conclusion: This is nothing to do with the browser. It is Lubuntu 16.04 that is giving the problem.
Finally I found an article that suggested adding 8.8.8.8 as an additional DNS server in preferences | network connections | wifi | ipv4 Settings. That fixed the problem !
What did I do and why did I need to do it ?
Why did hotmail work sporadically at the beginning, and again after the change in Firefox settings ?
Print-Screen button does nothing. I bound the keys to scrot as suggested by Vasa. That did not do anything, but scrot does work from the command prompt. So then I tried replacing lxsession-default as suggested by Joern. That did not do anything. I see at the end of the bug report they say the bug is fixed in 14.04. It is not for me ! Does anyone have any idea why this does not work ? As far as I can see the key needs to invoke a command in the appropriate environment. I can't see why this has been giving problems for so many years.
I have done a lot of Googling and I can't make sense of all the information.
I want to remotely operate a Lubuntu 14.04 machine from another of the same type. The remote machine has no monitor attached. I have Teamviewer10 on both machines.
The problem is that with no monitor attached, the remote desktop has only 1024x768 resolution. xrandr shows LVDS1 to be connected, although it isn't, and it only allows 1024x768 resolution.
The solution appears to entail using xrandr to test resolution, and then inserting the xrandr commands somewhere to execute the commands on startup/login, and make the change permanent. It is also possible that I need to create /etc/X11/xorg.conf and set up a dummy monitor. I really do not understand the steps entailed in that, and many Googlees say it does not work anyway. Some say I need a hardware dongle (I really cannot believe that you need hardware to do something like this - it must be a common requirement to use a machine without a monitor).
I would be very grateful if somebody could tell me if I am on the right track and make these ideas more concrete. I do not really want to hear about solutions using other remote viewing software (vnc etc). I may try these ideas in the future when I have time, but right now I want to make it work using Teamviewer (because thus far I have found it to be less laggy than other software when some of the screen contains video).
Many thanks.
