Status in linux-hwe-6.8 package in Ubuntu: New 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. System Information: Description: Ubuntu 22.04.4 LTS x86_64 Release: 22.04 GNOME Version: 42.9 CPU: 12th Gen Intel i7-1255U (12) @ 4.700GHz GPU: Intel Device 46a8 Host: ThinkPad X1 Carbon Gen 10 (21CB009UGE) Kernel Version: 6.8.0-40-generic Additional Notes: The problem does not occur with the previous kernel version (6.5.0-45).
