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!

Nvidia? it freezes my system sometimes as well. I go CTRL + ALT + F6, wait for the login to show up on text mode and then CTRL + ALT + F2 to go back, it usually fixes the problem

Nvidia?

I currently have no dedicated GPU, just a Ryzen CPU.

I go CTRL + ALT + F6, wait for the login to show up

Tried that just now - doesn't work. It seems like all devices are disconnected so I can't use the keyboard to change the VT.
