I have an ASUS A55V which comes with the infamous nVidia Optimus chipset. I installed bumblebee, and tested it correctly with optirun glxspheres. The problem is that I cannot change the screen resolution, from both the nVidia Panel and the Ubuntu Display utility, which is fixed at 640x480. The strange thing is that if I attach an external monitor, it's correctly detected and I can configure it normally with a decent resolution.

Laptop screen's resolution is fixed no matter if the external monitor is plugged in or not. And a curious thing is that even if the external monitor is unplugged, it still shows at the nVidia settings...

Any hints on how to solve this?

EDIT: using xrandr seems to work to add a new resolution and set it up, but the display is limited to the center of the screen. Here's a screenshot so you know what I mean:

Thanks in advance

If the xorg file exists, remove that and reboot. (it would be better if you remove xrandr. )

sudo rm /etc/X11/xorg.conf

That was it, thanks! But it freezes on startup... :( –  m0skit0 Aug 9 '12 at 9:41

The reason is that you certainly installed NVIDIA oficial driver... This computer is using optimus nvidia technology then you have to use bumblebee linux packages http://bumblebee-project.org/

Nope, it was with bumblebee. I already fixed this, thanks for the answer anyway :) –  m0skit0 Aug 31 '12 at 14:26

Looks like setting up a 16:9 resolution from the Display panel (1360x768) after adding it with xrandr works, but not directly from xrandr...
