Hi Nord,
Thank you for taking the time to open this bug report.
I have altered the package that this ticket is targeted toward, which
should fix the issue you hit while trying to ruin the "apport-collect
2077860" command that @paulw2u mentioned.
Can you please try running the command again to collect the data, and I
will go over it when it has been uploaded.

Title:
Black screen upon waking from suspend; keyboard mostly unresponsive;
issue resolved by using previous kernel version.
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
