2022-11-19 08:09:39 Oliver description Since kernel update to 5.15.0-53-lowlatency, I get no output at all anymore on the monitor. The monitor says 'No Signal'. Also when trying to change to a console with CTRL-ALT-F1 no output. When booting to the still installed previous version 5.15.0-52-lowlatency, all works as expected, and equally so when booting to a self compiled kernel 5.15.73-rt52. System is Xubuntu 22.04 LTS. The following debug output is from -52: $ uname -a Linux Hafendirektion 5.15.0-52-lowlatency #58-Ubuntu SMP PREEMPT Thu Oct 13 12:37:18 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux Since kernel update to 5.15.0-53-lowlatency, I get no output at all anymore on the monitor.
