Hi All
Recently I _upgraded_ both Laptop & PC from Mint 21.3 to Mint 22 after
several runs with a 'live' version; all appeared to be OK. Laptop was
first, not a problem. Few days later did the PC, all checked out OK:
but when my wife spent several hours writing to friends then playing
Mahjong she complained the screen kept going blank for a second then
coming back as if nothing had happened.
I've tried other programs and the same thing happens. but only on the
PC. My guess is something to do with the screen driver (?) but don't
know what to look at/for.
During upgrade several progs were backdated(?) some removed and others
upgraded. Did not take notes on these comments as they were only on
screen for a short while. It was a major upgrade, not a lot in the docs
gave any idea to the cause of the problem (to me).
This is only since the upgrade, no other changes to anything else.
Screen is a Dell 24", PC is NUC10 i7. How can I find out what's changed
to cause the problem.
