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.

I would try:

see if you can get logs of the resume process
suspend from a text VT and see if that changes the behaviour
boot into single user mode and try suspend from there
boot an older LTS or a newer test kernel and see if it has the same problem

Sorry, mate, I'm a Linux noob.

I have no clue where to find the logs for this.

No idea what a VT is.

Don't know how to boot into single user mode....

Fair enough, most of that isn't something a user should have to worry about.

VT is just Virtual Terminals. You always have one of them active, and in most distros you can switch to others by Ctrl-Alt-F1 through F12. In some distos it's just Alt-F1.

So if you press Ctrl-Alt-F2 you should be brought to a text login. For crazy historical reasons you may have to either press Ctrl-Alt-F1 or Ctrl-Alt-F7 to get back to your usual graphical session.

Arch docs for example: https://wiki.archlinux.org/title/Linux_console

OK, I tried that. Ctrl+Alt+F2 gives me a black screen.

Ctrl+Alt+F1 brings me back to my desktop.

Ctrl+Alt+F3-F6 all have a text login screen. F7+ don't do anything.

I was able to grab the journalctl logs. You can find them (and an extra bit about the computer state I was able to get) HERE.
