Begin with booting into Recovery mode
Then run the "Fix X option" there - this may do it
Do you use the Restricted driver? That is have you installed a driver?
If not use Hardware Drivers from the menu to install it
If you still have problems some editing may help
You have not told us which Mint you use - please always include version and edition
I'll assume you have the main edition and Elyssa or newer
Code: Select all
gksu gedit /etc/X11/xorg.conf
Begin with copying (mark all > Copy > paste in an empty file)
There is not much in that file but there should be a line
Driver "nvidia"
if you use the restricted driver or
Driver"nv"
if you use the open source driver
If not edit or add the line in
Section "Device"
In Section "Screen" add
SubSection "Display"
Depth 24
Virtual 1280 1024
EndSubSection
Remove the Depth 24 already present
Instead of 1280 1024 use the resolution you want if this was not it
Save your edit and reboot
Hopefully you have the resolution you want now
If not tell us which Mint you use - include version and edition and post lspci (l is a lower case L)
There is more we can do, but IO hope we don't have to use that
You asked how to restart X - Ctr+Alt+Backspace
