Title:
Lenovo T16 unable to wake up from sleep, screen blinking
Status in linux package in Ubuntu:
Confirmed
Bug description:
Lenovo T16 Gen1 (2022), Intel Core i7-1270P (12 gen) integrated graphics.
Running Ubuntu 22.04 LTS.
Unable to wake up from sleep - the screen backlight is on, but the
screen is solid black. After a while it starts randomly flashing with
a login screen for about ~300ms and also each time I type a character.
Also the "reboot" command hangs.
Tried with both "Suspend-to-Idle" and "Linux S3" suspend settings in
BIOS - same issue.
Not sure if relevant, but journal log contains these lines:
