I have a Dell XPS13 laptop and Dell WD19TB Thunderbolt dock and normally wo= rk on two dock connected screens + keyboard + mouse with the laptop screen clo= sed. If my laptop suspends in this state, and I then unplug the dock (e.g. to ta= ke the laptop away in the morning) then the screen stays blank when I try to resume. This started when Arch Linux updated the kernel from 6.3.9 (good) to 6.4.1 (bad) and I have tested it bad with every point release of 6.4 since = up to 6.4.12 and is also bad on current 6.5.3. I have generally been using the= LTS kernel (currently 6.1.53) to avoid this bug. If you wait about 60 to 70 secs then the screen does switch on. On 6.4 kern= els I had to wait about 2.5 mins, i.e. this delay has reduced on 6.5 kernels. --=20 You may reply to this email to add a comment.
