Ok, so here is what I did :
xrandr --newmode "1280x1024" 109.00 1280 1368 1496 1712 1024 1027 1034 1063
-hsync +vsync
wich returns :
xrandr: Failed to get size of gamma for output default
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)
Serial number of failed request: 19
Current serial number in output stream: 19
And when I do
xrandr --addmode VGA1 "1280x1024"
I get this :
xrandr: Failed to get size of gamma for output default
xrandr: cannot find output "VGA1"
