I would get a similar issue with video monitors that automatically scan each input for a signal. When the PC goes to sleep, or blanks the screen, the monitor would scan through the inputs looking for a signal. Sometimes they'd stop scanning after a few iterations, waiting on some random input. Trying to see a boot screen was impossible, as you'd have this race between trying to find a signal, and the monitor putting itself to sleep if there was nothing, and the PC's graphic card behaving oddly if it didn't detect it was being monitored. I had to turn off scanning in the monitor. Unfortunately, some monitors didn't have that option. -- uname -rsvp Linux 3.10.0-1160.81.1.el7.x86_64 #1 SMP Fri Dec 16 17:29:43 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
