Public bug reported:
Description: When I put my laptop into suspend and attempt to wake it,
the screen remains black. This issue does not occur when rebooting or
booting from a shutdown state. Additionally, the keyboard does not
respond as expected; for example, pressing Alt + F2/F3 or trying to
switch to an external screen using Super/Meta + P has no effect.
However, I can perform a soft reboot using Ctrl + Alt + PrntScr +
REISUB.
This issue occurs both with and without Wayland disabled. I attempted
the following modifications in the GRUB configuration without success:
GRUB_CMD_LINUX="nouveau.modeset=0"
GRUB_CMDLINE_LINUX="nouveau.blacklist=1"
The issue was temporarily resolved by booting into the previous kernel
version listed in Advanced Options for Ubuntu (6.5.0-45).
Steps to Reproduce:
Put the laptop into suspend mode.
Attempt to wake the laptop from suspend.
Expected Behavior: The screen should wake up normally, and the keyboard
should be fully functional.
Actual Behavior: The screen remains black, and the keyboard does not
respond as expected.
