--- Comment #17 from Valter valter.giovannetti@alice.it 2012-01-16 05:39:36 PST --- Ok. I made the suggestion of Alex in this way:
1) I gave the following terminal commands: xrandr - newmode "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 + hsync-vsync xrandr - DVI-0 addmode 1920x1080R xrandr - output DVI-0 - mode 1920x1080R
The monitor works fine as well!
2) Then I wrote these commands:
sudo nano / etc / gdm / Init / Default
After the lines:
PATH = / usr / bin: $ PATH IFS = $ OLD_IFS
and then I saved.
3) After restarting the monitor does not work anymore, but if I run the commands from the terminal
xrandr - DVI-0 addmode 1920x1080R xrandr - output DVI-0 - mode 1920x1080R
Then everything works!
What's wrong?
