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.

potential fixes.
