I've installed Ubuntu 12.04 on my laptop with integrated Intel graphics (Intel i5 460M CPU). The screen resolution is set to 1024x768 and can only be changed to 800x600, while my screen is 1366x768.
I have secondary NVIDIA graphics and Optimus installed and working. There's also a 1920x1080 display connected via HDMI which I'd like to configure for extended desktop (it's mirrored now). Disconnecting the external display doesn't solve the problem.
I've tried generating new xorg.conf with
Xorg -configure but it failed with a following message:
Number of created screens does not match number of detected devices
It still had dropped a file called
xorg.conf.new in my home directory. I've copied it to
/etc/X11, but it didn't help.
Ubuntu 12.10 did run in 1366x768 with mirrored displays, but it switched to 1024x768 instantly after login.

Jockey doesn't detect any drivers that could be used, but it did on clean 12.04 install. After the first update there are no drivers available.
Do you guys have any idea how to get it working as it should?
