Kernel 614, Nvidia 570.133, gnome
2nd. monitor attatched via HDMI
automatic screen blank after 5min
“Wakeup” leads to the error, that the applications on the hdmi screen are not positioned correctly anymore (upper half of the monitor is not usable at all) and re-positioning is only possible after “switch off” and “switch on” of the hdmi monitor. Build-in laptop monitor works as it should.
Solution:
- switch to kernel 612 (will test with 613 probably)
