Resolution stuck at 1280×1024 on 2006 iMac
When I first booted into Ubuntu the resolution was correctly set at the native 1920×1200 (iMac 24″ Late 2006, GeForce 7600 GT). Now, however, the resolution is stuck at 1280×1024 and nothing higher than that appears in preferences. What I have tried:
- install the Nvidia driver.
- apt-get upgrade
- Set the resolution in Terminal. (“Size 1920×1200 not found in available modes”)
