I have Toshiba 16" laptop with Kubuntu 12.04 installed in it. I am having some display issues like it goes blur while loading Plymouth and the mouse courser blinks all the time.
This is the output of xrandr -q
command:
xrandr: Failed to get size of gamma for output default Screen 0: minimum 1366 x 768, current 1366 x 768, maximum 1368 x 768 default connected 1366x768+0+0 0mm x 0mm 1366x768 0.0* 1368x768 0.0
The refresh rate is 0.0 Hz is showing in the display settings.
This is the out put of lshw -c video
