From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Tuxedo OS (Ubuntu-based) with KDE/Wayland - waking from Sleep freezes the computer. Help? (lemm.ee)

Hi all!

I recently installed Tuxedo OS with KDE and Wayland. I'm fairly new to Linux and, so far, the distro is great. With one caveat.

As far as power options go, everything works fine EXCEPT for Sleep. I can put the PC to sleep, but when I wake it up, I land on the login screen wallpaper with the login/password fields barely visible, as if frozen around the second frame of a fade-in animation.

Nothing works. The mouse cursor doesn't move, the keyboard doesn't do anything. The only way out of this state is to hold the power button until the PC shuts down and then turn it back on again.

I did some digging, but couldn't find a solution. Some threads mentioned modifying something in systemd, but those were from years ago, so I didn't want to risk that.

One fairly recent thread had a proposed solution of adding "mem_sleep_default=deep" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

That didn't work for me, though.

I'd love to fix this, but I'm out of ideas. Any help welcome!

EDIT

Forgot it might be a driver issue, people were complaining about Nvidia gear!

I currently don't have a dedicated GPU. I only have Ryzen 7 7800X3D running on MSI B650 Gaming Plus WIFI ATX AM5 MoBo.

There's no Windows, I nuked the drive before installing Tuxedo OS.

In the sense of windows boots and changes values of the bios that aren't saved between boots. Similar to how fan curves can be changed or GPUs overclocked.

I did some more digging and in System Settings → Screen Locking found an option called "Lock after waking from sleep". Since the OS was freezing on the lock screen, I disabled that to see what happens.

The OS freezes completely just before the shutdown to sleep - I can see ALL devices get booted out - network, BT, audio, mouse, keyboard - everything gets disconnected and then freeze happens.

I have updated the BIOS to the latest version and since then the freeze happens BEFORE the OS goes to sleep. As in: I click the Sleep button, everything freezes, that's it, the screens never turn off.

So it doesn't seem like it's something that's happening in BIOS during wake-up/reboot, right?

Does the system also freeze on lock screen without the sleep? superkey(winkey)+L

I'm no expert on TuxedoOS you might need to contact their support https://www.tuxedocomputers.com/en/Help-Support.tuxedo I also found this while digging. https://www.reddit.com/r/tuxedocomputers/comments/17ai79z/how_to_enable_hibernation_in_tuxedo_os_encrypted/

No, lock screen works fine.

Cheers for the links, I'll look into that!
