I just do not understand why update manager, when showing the list of updates the will get installed includes items where the checkbox in front is unchecked and where it is not possible to check the boxes / enable the updates? What is a user supposed to do with that information? Ubuntu Pro is enabled for that machine, so it is not the list of Pro updates ...
We want to use sshfs to mount directories from a server on a client, bit some user and group ids do not match between those machines. The requirement is that user ownership is mapped correctly and the client is able to change the group of files to those groups where the local and remote user have the appropriate permissions.
After testing that sshfs HOST:DIR MOUNTPOINT -o idmap=user works and mounts the directory properly (but obviously does not map the user and group ids correctly) I tried sshfs HOST:DIR MOUNTPOINT -i idmap=file,uidfile=uidfile,gidfile=gidfile with the proper content of uidfile and gidfile.
This then does not mount anything at all, and also does not show any error message either on the console or in the logs!
When running the command with the debug option -d, one can see that the command exits with exit code 1, doing everything the command which uses idmap=user does in exactly the same way.
I tried this on several machines, with the same frustrating result on all of them.
ssfhs version is 3.7.1
It is hard to believe that such a blatant bug is the software and apparently not documented - is there anything known about this, any workaround?
Just installed Ubuntu 20.04 on a ThinkPad W451 where the screen resolution on the laptop is 2880x1620 and attached a second monitor with resolution 1920x1080. Sadly there seems Ubuntu either shows tiny fonts on the laptop monitor, or if the fonts on the laptop monitor are OK, the windows and fonts on the second monitor are huge.
In the Displays settings, there is a scale selection for either monitor, but the scale cannot be independently set: if I set it on one, it affects the other.
Is there a way to use dual monitors so that the font sizes would just adapt to the actual DPI for each monitor? I cannot believe that such a fundamental thing is still not solved in 2020: for each monitor, if we know the DPI, we should be able to draw things with the intended size. I tried this with the default window manager, xfce4 and Mate, and all of them get it wrong.
This seems to be very badly documented, and while there are many questions similar to this one, none really deals with this exactly, nor seems there to be a solution.
I am on Ubuntu 18.04 LTS using the xfce4 desktop and I normally use UK English, my physical keyboard is UK English.
However I need to write other languages now and then, for this reason, I use UK English (dead keys) for languages with accents and umlauts.
I was also able to get Farsi (Persian) to work: just choose Keyboard Preferences - Layouts, hit the +Add button and add Persian. When I enable that language the Farsi characters will show up when I type.
In order to see which character appears for which key on my (UK) keyboard I can look at the layout using the "Show Current Layout" function. When I show the "onboard" virtual keyboard, it automatically switches between the UK, UK dead keys and Farsi characters which makes it easier to enter the correct characters.
HOWEVER: when I try to do the same for Korean, nothing works at all. There is a "Korean" option in the same list from which I selected Persian, but choosing it does not change anything and the layout shows latin characters instead of Hangul (Korean characters).
After consulting many pages on the web I got fcitx to run but while the fcitx menu has an option to choose a virtual keyboard and show it, Korean never shows up in the list, even if the Korean input method is selected. I found no way to figure out what the layout of the korean keyboard is and how to enable a Korean virtual keyboard. Enabling Korean/Hangul also works only rarely, the language often changes to English by itself or just by moving the mouse.
When I activate the Korean input method and I get it to work in a window, as soon as the virtual keyboard display is toggled, Korean is deactivated and I am back to Latin (which is also shown in the virtual keyboard). Also while I can type in a terminal, I cannot get it to work in Google Chrome at all.
Am I missing something or is it simply not possible to enter Korean/Hangul using a virtual keyboard using Ubuntu as of 18.04?
I mainly use Google Chrome these days under Ubuntu (18.04) with the MATE desktop manager, but there is one thing I could not figure out yet:
If there is a link on a web site that points to e.g. a "bib" file, i.e. a BibTeX file with extension ".bib" Chrome wants to download it. All bib-files are really text files so I would want chrome to just show the text of the file in a browser window like it would for a text file (with extension .txt). The second best option would be if I could make Chrome to open the file in e.g. gedit based on its extension.
With Firefox it is possible to configure this directly in the browser, but Chrome delegates this, I think, to the OS, so how make sure it works in Ubuntu (at least the second-best option)?
Does this require different solutions depending on the desktop used (Unity, XFCE, MATE)?
UPDATE: most problematic links are those where the link is not a static link to a file with .bib extension, but some link to a script or a javascript link. Ultimately the save as dialog that pops up shows a filename with a .bib extension, but it may be that what is sent back has an odd mime type. So I guess what I would need is that the .bib extension of what gets sent back overrides any mime type and gets handled as plain text.
When doing sudo apt update I get the warnings shown below. This is very annoying and somewhat alarming to see, but why does it even happen?

After booting the laptop, the keyboard does not work at all any more: in the login screen, none of the keys does anything. The touchpad can be used to move the mouse pointer, but clicking on a user name or an icon in the panel does not do anything either. When I boot into 4.13.0-39 instead, everything works as expected.
Oddly, if an external USB keyboard is attached when logging in, both the USB keyboard and the laptop keyboard work and the laptop keyboard continues to work after removing the external one.
I have a fresh install of Ubuntu 18.04 and I am using the Mate desktop. On my Razer Blade laptop, when I close the without logging off, then open the lid again, I have to enter my password three times to get back in.
The first unlock screen seems to come from the gnome screensaver, the second and third from mate screensaver. I tried simply killing mate screensaver as an experiment but after waking up from suspend, I get all three lock screens again and mate-screensaver has been restarted somehow.
When I kill gnome-screensaver instead, closing the lid will not suspend my computer any more nor will the screen get locked after a certain timeout.
So there appears to be no simple way to make it work as it should. Is there a way to fix what obviously has got to be an annoying bug?
Is there a bug report about this somewhere, this really should get fixed.
I would probably prefer to have everything handled by gnome-screensaver: not only does it look better, I also use the Ubuntu desktop every now and then and would still want screen locking to work there.
After upgrading Ubuntu to 17.10 I cannot run LibreOffice at all any more. I get a pop-up window with the text:
"The application cannot be started. LibreOffice user installation could not be processed due to missing access rights. Please ensure that you have sufficient access rights for the following location and restart LibreOffice:
/my/homedir/.config/libreoffice/4 "
This happens with the default version available for Ubuntu 17.10 and it also happens after purging and re-installing and after purging and re-installing version 6.0 from the PPA.
All directories from the path /my/homedir/.config/libreoffice/4 are owned by my user and my group and have permissions drwxr-xr-x for directories and -rw-rw-r-- for files in them.
So the message LibreOffice shows to me is apparently a lie.
After upgrading to 17.04, when I start LibreOffice, I get the following error messages:
/usr/lib/libreoffice/program/javaldx: error while loading shared libraries: libreglo.so: cannot open shared object file: No such file or directory
Warning: failed to read path from javaldx
/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: libreglo.so: cannot open shared object file: No such file or directory
I've tried to completely remove and reinstall the libreoffice package. I've checked and there are no PPAs in the sources list.
Update: turns out the file libreglo.so exists in directory /usr/lib/libreoffice/program/. When I add this directory to LD_LIBRARY_PATH LibreOffice works. But why is it apparently mis-configured by default?
I am using tracker and I am using tracker-preferences to configure which directories it should index etc. However I see strange behaviour so I would like to look at the actual configuration file or settings tracker is using.
I could not find any hint as to where to look though: there seems to be nothing in the gconf registry, nor any config file in ~/.conf or ~/.gconf.
I am using an encrypted hard disk for backing up my (also encrypted) laptop disk, running Ubuntu 15.10 64 bit. The built-in laptop disk works fine but the external USB disk, after working for somewhere between a few minutes and a few hours, suddenly switches itself back to being encrypted and shows the password prompt. This happens even though I keep choosing "remember forever". Often, when I then re-enter the password, either it does not work and the dialog is shown again, or the system claims that it cannot mount the drive because it is already mounted.
I thought maybe this is the problem with the physical disk and I attached a second encryped external usb drive. Now I am seeing the same problems for both disks, of completely different make and model. Although I have seen this problem with 15.04 my impression is that is has become even worse.
The bottom line is that now both my external USB hard-disks are essentially unusable and the whole situation is extremely annoying.
Is this a known issue, and more importanly, is there anything that can be done to fix or avoid these problems?
The error message when trying to unlock again and the system claims something is already mounted is:
Error unlocking /dev/sdd1: Command-line `cryptsetup luksOpen "/dev/sdd1" "luks-xxxxxx-xxx-xxx-xxx-xxxxxxxxxx" ' exited with non-zero exit status 5: Device luks-xxxxxx-xxx-xxx-xxx-xxxxxxxxxx already exists. (udisks-error-quark, 0)
I have a Lenovo W550s which contains a 3D Nvidia graphics chip, and I run Ubuntu 15.04 64 bit on it.
The "Additional Drivers" dialog only shows some processor microcode firmware but does not offer a proprietary driver for the Nvidia graphics chip.
lspci reports: "3D controller: NVIDIA Corporation Device 137a (rev a2)"
Is there a way to use the proper driver for full 3D support without resort to hacking?
I find it odd that in the year 2015, there is still a problem with operating systems not dealing correctly with higher DPI values. So if the resolution is high for the same screen size, all fonts, icons, panels, windows etc. will be relatively too small, and sometimes just tiny.
It seems that there may be a partial solution for that in Unity, but I am using the Mate desktop. Is there a way to just scale everything up so it is bigger - fonts, icons, panels etc?
My resolution is 2880x1620 on a 15 inch monitor and everything is so tiny it is completely impossible to use. I could decrease the screen resolution, but the alternative, lower resolution lead to different aspect ratios, thus distorting everything. It also seems wrong to lower the resolution just to fix this, instead of the OS scaling the size up at the higher resolution, which should show better, more crisp graphics and fonts.
I try to create a startup disk with Ubuntu 15.04 64bit on a 16G USB stick. When I start the "Startup Disk Creator", it will show progress of "Copying files..." until about 49% complete, then hangs forever. No error message shown, no hint if anything is still tried or being done or if I am looking at a corpse. When I press the "Cancel" button I get a confirmation dialog showing "Do you want to quit the installation now?" but when I click "Quit" there, now that dialog also hangs. After killing the process, when I retried but disabling the extra data region of 1G that it creates by default, the process indicator went to 96% complete and then kept being stuck there.
I have Ubuntu 15.04 with all the latest updates on 64bit machine. I prefer to use Mate since it so far was the only desktop manager that did everything I wanted and did none of the things I do not like.
For some reason the indicator area in my panel only shows the volume indicator. There is no icon for the network-manager applet (but nm-applet is started!) there is not icon for the battery status, all other icons that were previously there are now gone.
There also seems to be no way to add an indicator applet for which of several configured keyboards should be used (previously there was an applet where I could select between en/es/de etc)
How could that happen and how can it be fixed?
The internet is unfortunately full with instructions which either do not apply (older versions etc) or make things worse.
I have bought the Fluendo DVD player software a while ago because it always was the only software capable of playing all the DVDs I had on my computer. But this program seems to have been quietly abandoned: Software center tells me "not available for your current Ubuntu version. Please contact your vendor for an update." However the info page for that software does not even show a vendor! I find this very frustrating especially since some DVDs which have worked fine with Fluendo cannot be played with alternatives like SMPlayer or Xine any more. For me, another small detail that made Ubuntu worse. :( Is there any other proper DVD player program which can properly handle all the various copy-protected DVDs out there, which all play fine on consumer DVD players or Windows computers with purchased player programs?
I would like to be able to access the files on my Ubuntu laptop from my Android phone and tablet. Ideally, I would want to do this over my own secure Wlan and then over sftp or Samba shares. Since there is no Wlan that is accessible to me where I want to do this, I want to create that Wlan network with the laptop's built in wifi or a Wifi USB stick. This Wlan should be accessible by ordinary Android devices.
Here is the problem: when choose "create new wireless network" in the network manager applet, the network created is NOT available in any of my mobile devices. I am told this is because it is an "ad hoc" network which is not supported by these devices.
There are some instructions on how to create managed networks (not sure if this is the correct term) but those look very complex and often differ among each other. Also, all of these instructions are for making the internet connection of the laptop available over Wifi - which I do not need. All I need is for the Wifi network to make the notebook files available, so the only host that needs to be accessible over this Wlan is the notebook.
Is there a (hopefully) easy way to just start such a WLan network? If not, would it be possible to achieve what I want with some other kind of hardware (other than a simple USB Wifi stick), so I can create a Wlan where my laptop is the only accessible host?
I think with the increasing number of mobile devices, and with both the mobile phones/tables AND the laptop having their Wlan hardware built right in, it is odd that there is no easy way to connect them directly and without the necessity that both devices have access to some other Wlan.
EDIT: I think this may be not, as suggested a duplicate, since the answer to the other question, as well as many other often slightly different recipes, try to share the internet connection of the computer that provides the access point, while I just want to access files on this computer or use services there, simply using the IP address. So what I was looking for is the easiest way to achieve this. I think I may have found a solution in the meantime which is less complex as the answer for the suggested duplicate, but I cannot seem to create an answer here.
