Hi all. I had a really nice setup on Chimaera where I had one user for gaming and one for everything else. I had stopped using slim because I wanted to avoid having xorg running as root so instead my computer would require me to login on a virtual terminal (Ctrl+Alt+F1) and then I would run startx to start XFCE. This worked perfectly. Both users were able to run separate Xorgs on different virtual terminals and I could switch between them by Ctrl+Alt+F* at will.

After upgrading to Daedalus if I try to switch away from the first Xorg, even if I'm just switching to a plain virtual terminal and not another xorg, even if there's no other Xorg running, the first Xorg crashes and when I switch back to it (Ctrl+Alt+F1) I'm already dropped back at the console.

I found these in the xorg crash log in my user directory:

I saw in the release notes for Daedalus that there some changes around running xorg as non-root but I don't understand how they apply to me since I do not use any login manager like elogind, nor do I want to start using one if that's possible. But I do have elogind installed because it's a dependency of digiKam. I'd rather just use startx after having logged in on the console. My user is a member of the video group, I checked again. I'm not sure why I get this: "AMDGPU(0): failed to set mode: Permission denied"

Any ideas? Am I unknowingly using a login manager?

Thank you!

EDIT: I tried installing seatd and now I can switch out of my active xorg and into a VT but it will fail to start a second Xorg under a different user account. I removed it again for now since I think just solving the permission denied issue will make everything as it was before the upgrade.

What the title says. Version 1.24.0 on Chimaera. Print preview in Atril shows a progress bar quickly and then nothing, it just goes back to showing the document as is. You can fix this by installing evince. I thought I'd post in case anyone encounters this in the future.

This is driving me crazy. I am making a bash script that is given one or more files and will search with location for other locations that the same filename shows up. So I need to make this work given the whole filename. I intend to use this script as a custom Thunar action and it actually works fine for files that don't have square brackets in their name. But I have a file named:

5481[2].jpg (image).html

I want to use locate to search in what other locations it exists. Specifically

locate -b "(image).html"

will show the file, so the file is in my mlocate db. But trying to search with

locate -b "5481[2].jpg (image).html" 

returns zero results!

Even leaving the bash script aside for a while and simply opening a terminal and typing "locate" then the start of the filename and tab completing it, which escapes the filename with backslashes, still returns zero results while it works for any other file without square brackets.

What gives? What's so special about these square brackets that locate refuses to use them in a search expression? The same issue applies to all my files with square brackets in their filenames.

My only other option would be to find a way to turn a filename into a regex and then user the regex mode of locate. Is there a command that I can filter a filename through to turn it into a proper regex?

Thank you.

I'm assuming gvfs is what Thunar uses when I go to a url like sftp://user@123.123.123.123/some/path. Thunar seems able to browse sftp locations with gvfs, gvfs-backends, gvfs-common, gvfs-daemons and gvfs-libs installed but double clicking files to open with Mousepad will simply open an empty document called Untitled 1 as if I just opened the application without any arguments. Trying to open files with Mousepad from the terminal like so:

mousepad "sftp://user@123.123.123.123/some/path/filename.txt"

will give:

Invalid URI: "sftp://user@123.123.123.123/some/path/filename.txt"

I saw somewhere else on the internet that I should install gvfs-fuse as well but it didn't seem to make any difference.

Any ideas please? :-/

Hello. I already solved this issue but it took me too long so I thought I'd document the solution here if anyone else has the same problem.

Hardware: https://ubuntu.com/certified/202111-29708/20.04%20LTS
Renoir graphics with Ryzen 5 5625U.

Symptoms:

• /sys/class/backlight/acpi_video0/brightness exists and contains values and can be changed but will not change the actual brightness on the laptop panel.

• Whenever a value is written to the above file, the Display Settings pop up. Yes, the actual xfce4-display-settings program is started. I'm assuming that it detects a display change. It even pops up if you use the Fn buttons to change the brightness if you have given control of the brightness to xfce4-power-manager (which you should).

• The Fn keys will emit "dell_wmi: Invalid length of WMI event" but this is a red herring, ignore this sort of warning.

• Your laptop's panel will only go up to 70Hz or 77Hz.

I tried many of the solutions that float around the web and only a combination of two of them plus something that I found myself in synaptic worked. Specifically:

(As root)

• Enable backports and install the kernel 5.18.0-0.bpo.1-amd64 (headers and image)

• Edit /etc/default/grub and change the CMDLINE to: GRUB_CMDLINE_LINUX_DEFAULT="quiet amdgpu.backlight=0"

• Run update-grub.

• Install firmware-amd-graphics

Reboot and acpi_video0 will go away and instead you'll have amdgpu_bl0 which actually works with Fn keys and by writting values to the /sys/class/backlight/amdgpu_bl0/brightness file. You'll also have 120Hz refresh rate.

I had tried individually the three important components of the solution and they didn't seem to work.

The only other issue that I encountered with this laptop was that the external mic doesn't work with ALSA at all, and the internal mic works but has no volume control. Pulseaudio somehow makes them work, which makes me think that there is a way to make them work with ALSA too, since PA uses ALSA if I am not mistaken. I may try to solve that in the future since I dislike PAs overhead (CPU and latency).

I hope this helps someone.
