Ramon Suarez's questions

I've reinstalled my laptop by deleting my previous Ubuntu 20.04 install and fresh installed Ubuntu 21.10 (updated to latest available updates).

Now that I'm trying to print a lot of PDF files with a simple lp * as I was doing before, only one document is printed and nothing else happens. When I try to print a single document with lp nothing comes out of the printer.

The Wi-Fi printer (Brother_HL_L2350DW_series) has been selected as the default (and only) printer. When printing from the GUI it takes a bit to launch but it prints all the documents fine one by one.

I don't remember having had to do anything to install the printer. If I do a search for drivers it says "No suitable driver found".

How can I figure out what's not working and fix it? It is a great time saver for me when I have to print a lot of one page documents.

Thanks!

I'm having an issue since I updated to 20.04 that I've not found answer for going through the login loop questions already published.

The loop I get into happens after I try to log back in after locking the screen. Everything looks normal and after entering the password the desktop or whatever window was open is shown and then Ubuntu goes back to the login screen with a different theme that stays after entering the password again. The new theme makes it very hard to see whatever is on the top bar, changing volume with the mouse, or when I search for apps to launch (all icons are black).

This behavior happens always, but sometimes I need three logins instead of two. If I go to a terminal window with the function keys and then back to the graphic interface things look normal but then I have to log in again with the same issues.

When coming back from Suspend, I directly see the wrong theme login screen.

Thanks for your help.

I just upgraded to Ubuntu 20.04 LTS Focal Fosa and I've lost the use of the Super key to bring up the search window with the Spanish and Belgian keyboard layouts (2nd and 3rd layouts). The Super key is still working with EN (1st language in the list). There's a bug already being worked on (see comment by @to-do below)

I've tried adding it to the Keyboard Shortcuts in settings but it is not recognized.

This happens both with my laptop keyboard and an external keyboard. The computer is a Dell Precision 5520. There was a firmware upgrade during the upgrade from 19.04.

As a workaround I'm using Super+S , but I would prefer to have just the Super key working in all layouts as before.

Since updating to 19.04 a lot of files that used to show up in Recent are no longer showing up (ie downloads), and I have to search around to find them.

I've done some searching but have not found anything that explains this.

Do you know if this is the result of a policy change or something is broken?

If broken, can you help me fix it?

Thanks!

With the update to 19.04 my dell repository is not working as it is marked as not signed. This is the error I get:

Ign:11 http://dell.archive.canonical.com/updates xenial-dell Release.gpg

W: GPG error: http://dell.archive.canonical.com/updates xenial-dell Release: Detached signature file '/var/lib/apt/lists/partial/dell.archive.canonical.com_updates_dists_xenial-dell_Release.gpg' is in unsupported binary format

    N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I've tried with the xenial-dell and bionic-dell. You can see all the repos here.

There are Release and Release.gpg files in both repositories:

I've searched on Ask Ubuntu and elsewhere but I have not been able to find a working solution.

I updated my machine yesterday to Ubuntu 17.10 and suddenly I can no longer use the launcher to start Atom editor. It was installed as a snap and can be launched via the software app (it is installed) but it will not show up when doing a search . I cannot set it as a favorite either.

The version of my Atom snap is 1.21.1 (updated 10/19/2017).

  $ snap --version
    snap    2.28.5+17.10
    snapd   2.28.5+17.10
    series  16
    ubuntu  17.10
    kernel  4.13.0-16-generic

There's a thread about this but I can't find/understand a solution there.

Update: I made a bug report on the developer's github. Atom says that they don't maintain the snaps, so it is not their issue.

I have two Google Drive accounts connected via Gnome Online Accounts (GOA). I can browse them with nautilus but I have not found how to access them through the command line. Shouldn't they be mounted somewhere even if they are network shares?

My objective is to be able to diff both to see if there are any files missing, as I'm copying files between them. I've tried copying the files directly via nautilus, but it stalls and whenever the window is not greyed out the message is that it will take months.

Thanks for your help

I recently installed the Mention beta for Ubuntu, a tool to track mentions in social media. The install is a bin file that you have to install from the command line. There's no uninstaller and apt-get remove mention does not find the package. How do I remove it?

I really like the "recent documents" bookmark that appears when I'm adding a file with a dialog opened by a program. How can I do so that it always appears among the bookmards in the sidebar when I open a new nautilus folder view?

For the last few months I've been having a lot of problems syncing with two computers that I reinstalled and encrypted the drives. It is happening with all the programs I mention in the subject. Can the encryption of the disk be the cause of the problem?

My encrypted SSD uses LUKS version 1, LVM2 PV

Update: My home does use ecryptfs. This is the relevant line of df -T:

/home/ramon/.Private ecryptfs 118659356 86991664 25633468 78% /home/ramon

When contacting the customer service of Insync they ask to send the logs where do I find them in Ubuntu?

I work in a shared office and I have the heaphones plugged in in order not to bother my colleagues with the poping sounds of chats and incoming calls. The problem is that I miss most of my calls and chats because the current alerts are just to hard to notice.

Is there a way to make...

• the full screen flicker,

• or to bring up an obnoxious message right in the middle of the screen,

• or a full status bar blink while not focused on the messaging-calling

  app so that I will not miss the calls?

I've gone through the full dconf-editor without finding anything helpful.

There may be a good lead here: How to make Skype use notify-osd? but I don't know how to take advantage of it to change the notifications.

There's a USB key with changing lights project but it does not work with Linux. Besides, why add another hardware piece when you can just put it in the interface you are looking too?

This is not a whitelisting problem, all my apps show in the tray.

I use a USB disk to backup my Ubuntu machine and store the video files I work with. It is formated to ext4 and uses LUKS encription. When I was using 12.04 it was working flawlessly and would mount automatically in every reboot. I just had to enter the passworkd once in a window where I also told the system to remember it forever.

It no longer mounts after I upgraded to 12.10. I've tried the different UUID and the /dev/mapper in /etc/fstabbut it never gets to work at startup. I get the error that the drive failed to mount and offers me to mount it manually or skip. It may be related to a change in the way disks are mounted in 12.10, where I found that in the /media folder there's now a subfolder for my user and then the disks mount in their own subfolders within that one.

I've managed to make my current fstab setup work after boot but only after first mounting the drive via the app Disks, after I enter the password there.

If I don't go through that first I get an error message telling me that the disk does not exist. In these pastes from the terminal you can see the difference in blkid after I used the Disks workaround:

ramon@ramon-ldc-20120921:~$ sudo mount /media/ramon/Respaldo/ [sudo] password for ramon: mount: special device UUID=34241b59-8d65-4e8a-bda4-ef4ab6935eb3 does not exist ramon@ramon-ldc-20120921:~$ sudo blkid /dev/sda1: UUID="71acf30d-abe7-41f1-b678-e9d5db5fa04f" TYPE="ext4" /dev/sda5: UUID="944dde6d-6232-4b96-b347-4d3dff2994f3" TYPE="ext4" /dev/sdb1: UUID="841e796b-e384-4b83-9432-10fa0d863600" TYPE="crypto_LUKS"

Here I used the Disks app to mount the disk:

ramon@ramon-ldc-20120921:~$ sudo blkid /dev/sda1: UUID="71acf30d-abe7-41f1-b678-e9d5db5fa04f" TYPE="ext4" /dev/sda5: UUID="944dde6d-6232-4b96-b347-4d3dff2994f3" TYPE="ext4" /dev/sdb1: UUID="841e796b-e384-4b83-9432-10fa0d863600" TYPE="crypto_LUKS" /dev/mapper/luks-841e796b-e384-4b83-9432-10fa0d863600: LABEL="Respaldo" UUID="34241b59-8d65-4e8a-bda4-ef4ab6935eb3" TYPE="ext4"

This is the line I have right now in my /etc/fstab:

UUID=34241b59-8d65-4e8a-bda4-ef4ab6935eb3 /media/ramon/Respaldo ext4 defaults 0 2

I've already done some research and have not found an answer here in AskUbuntu nor elsewhere. I even tried with a couple programmers that use Ubuntu in my coworking space, but they've never faced such issues before and all we could get to do is what I've shared here.

What I want is that the disk automounts everytime I boot the computer.

Thanks to all for your help and for spending your valuable time going through this post.

Ubuntu does not switch back automatically to only monitor present when booting after disconnecting external monitor.

Here's a video showing what happens. I get to the login window and everything looks ok, then I type my password, the desktop image shows up and... everything goes blank. It does not happen when I just login as a guest.

When possible I work with my laptop connected to an external screen via the VGA port. The problem comes when I boot the computer without that secondary screen connected:

• The login screen comes out ok.
• After login the screen goes black, but I can hear the login sound.
• If I hit ctr + alt + backwards-delete and login again sometimes it is fixed, but not all.
• If I log in as a different user everything is OK. Then I log in as my user and sometimes it works.

To have a screen I have to plug a monitor. Although I have turned on the laptop display with that monitor on, if I reboot it goes blank again after login, even if I turn off the external monitor before turning off the computer.

I've managed to get my screen back with my username after going into recovery mode, but only sometimes. Failsafe would not load after second screen asking me what I wanted to do (no mouse to click nor keyboard working).

My computer is a LDLC Aurore BB1-i5 -8 -S1.

Which is the configuration file that keeps the information about the monitors using Displays under lightgdm and where is it? I guess if I could edit it I may have a chance :)

One of the things I tried following a solution in another post was removing my monitors.xml file, but it does not work and I don't know how to create a good one that I could use now.

When doing DISPLAY=:0 xrandrI get:

Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192
LVDS1 connected (normal left inverted right x axis y axis)
   1366x768       60.0 +
   1360x768       59.8     60.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)

This is the full dmesg after activating sudo xdiagnoseas Bryce sugested. (If you tell me the relevant parts I will paste them here)

When conecting the external monitor, only the external will work, although I can see using Displays that the computer thinks that both are working.

I've asked the question in Launchpad but have it keeps on expiring without any feedback. In my opinion Ubuntu should be able to detect automatically that there is no external monitor present and switch to the laptop monitor.

There's a similar question here, but it does not apply to my case External monitor set as primary even when disconnected from laptop

Update: For clarification, the problem happens only with my user and once I log in. I even get to see the screensaver for about a second, and then it goes blank. Tried Bryce's example (see his answer below), but it did not work. This is the info I get from tty1 with Display=:0 xrandr: – Ramon Suarez Jul 9 at 16:36

I have an HP Pavilion DM3-1120eb laptop with an Nvidia Geforce G105M graphic card, running a fresh Ubuntu 12.04 Precise Pangolin install. When connecting to a new Samsung S23B550 23 inch LCD monitor the HDMI will not work and the VGA connection will not allow for 1920*1080 resolution. The result is a small resolution (1024*768) that does not look good (fuzzy) and I cannot watch YouTube videos (the video box keeps on moving to the right and back) and the same flickering effect happens with droping menus and Google's suggestion box.

I've tried multiple solutions sugested in posts with no good result (including installing the drivers downloaded from the Nvidia page).

As far as I can guess, the problem is that the NVIDIA card is present but not recognized and thus the drivers do not work. Originally the drivers were installed (nvidia-current and the rest, all updated), but could not configure them with nvidia-config (says driver not present) and they did not show up with jockey-gtk. There's also been an error message about GLX not being present either. SCREENSHOT

For the HDMI the monitor says that there's no signal of MHL is not installed.

The computer is running now with no Nvidia drivers and no xorg.conf file (it gives me the best resolution). VGA will not even recognize the monitor as a 16:9.

This is the result of xrandr:
