maverick unknown screen and external monitor not detected

[Nicolas Maleve]

Binary package hint: xorg

Trying to connect my laptop computer to an external monitor. The screen is simply duplicated and I can't change this via Monitor Preferences.

When opening the System -> Preferences -> Monitor, the monitor of my laptop is unknown, 'Same image' is greyed out, refresh rate is zero, and I only have the choice for one resolution.

With xrandr the attached monitor is not detected:

xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768 0.0*

When booting with editing grub: i915.modeset=0, the Monitor Preferences gives more resolutions, but no image appears on attached monitor.

I am seeing the same problem on my Sony Vaio PCG-TR2 laptop with external VGA monitor. The screen is duplicated at the laptop resolution (1280 x 768) and so only fills the top part of my external LCD display, which has a resolution of 1280x1024. Only one monitor, "Unknown", appears in monitor preferences and I can not change the resolution, as only 1280x768 is available. Hitting detect monitors doesn't help.

The same setup worked fine some time ago when I was running Ubuntu 9.10. I am now running Ubuntu 10.10

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version. Thanks in advance and sorry for the late response.
