4.3 Permanently adding undetected resolutions
Once a suitable resolution is found using xrandr, the mode can be permanently added by creating an entry in /etc/X11/xorg.conf.d/:
/etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor" Identifier "VGA1" Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync Option "PreferredMode" "1280x1024_60.00" EndSection Section "Screen" Identifier "Screen0" Monitor "VGA1" DefaultDepth 24 SubSection "Display" Modes "1280x1024_60.00" EndSubSection EndSection Section "Device" Identifier "Device0" Driver "intel" EndSection
Replace intel with the right driver, e.g. nvidia. When the X server is restarted, you should be able to set the new resolution.
If this does not work for you, try removing the Screen and Device sections and just leaving the Monitor section. [3]
