--- Comment #18 from Valter valter.giovannetti@alice.it 2012-01-16 09:22:40 PST --- Hello to everybody, again.
I stand corrected.
After further tests, after rebooting, it is sufficient only to give the command:
xrandr - output DVI-0 - mode 1920x1080R
so that the monitor is fine.
Why doesn't it execute the last command?
Does it exist another way to make the setting permanent?
And how?
