Public bug reported:
Hello There,
I'm using ubuntu desktop for about 12 years Using the LTS released.
and using External monitor (Acer G195HOV) vga port connected to my laptop
hp2540p.
It's working good within ubuntu desktop 16.04 LTS,
and "working for a while" after upgrade to ubuntu 20.04 LTS.
After the kernel updated to version 5.10 the external monitor stop working....
Blank screen.
FYI:
Currently I'm using ubuntu 20.04 with kernel 5.15.
