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.

First, update your computer's BIOS/firmware. If that doesn't fix it, then try Arch, or Fedora beta. If the problem exists there too, then it's a kernel issue in general, and it might get fixed in the future. OR, if the computer BIOS is buggy, Linus has been clear that they won't do workarounds for buggy firmwares. In which case, you'd need a new computer that's actually compatible with Linux.

Most of the computers out there have buggy firmwares that go around for Windows, but Linus has been adamant that he wouldn't do workarounds because they bloat the kernel.

Well, I updated the BIOS - no change so far. I guess I'm stuck without Sleep. :/

You are not alone. There are many laptops that don't work with sleep on Linux. I used to have one of them, a Dell 3150. I simply disabled sleep in bios, and be done with it. I now buy laptops that I know they work 100% with Linux. It's impossible for Linux to support every hardware in the world, when these are specifically are made for Windows.

I have it too now with KDE. Seems like something new

I'm curious, did you dig around the BIOS/UEFI to see if there are any ACPI power states that can be disabled?

I had a very similar issue and turning off S3 worked around it. Of course, that meant higher power usage during sleep but it was a compromise over buying new hardware.
