Public bug reported:
Hi,
the display of my Lenovo laptop normally wakes up after suspend mode
(lifting the lid).
Since a software (kernel) update a few weeks ago, the screen stays
black.
It is very anoying, as I have to reboot after each suspend.
Ubuntu release: Ubuntu 24.04.2 LTS
Laptop: Lenovo ThinkPad T14s Gen 2a
System: AMD Ryzen™ 7 PRO 5850U with Radeon™ Graphics × 16
Debug information should be added automatically.
Best regards
