View Full Version : [ubuntu] Cannot detect my laptop monitor after reopening the lid

August 10th, 2011, 02:33 PM
If my laptop is connected to an external monitor and I close the lid, the dual screen is simply transferred onto one screen in my external monitor. However, when I reopen the lid, the whole screen is still on my external monitor, and it never comes back again. My laptop monitor is black.
If I go to NVidia X Server Settings, it says:

Unable to load X Server Display Configuration page:

Failed to read a display device name on screen 0 (on GPU-0)
while parsing metamode:

': 360x200 @360x200 +0+0'

It seems to me that NVidia cannot recognize my laptop monitor.
The simplest solution is to reboot, but is there any other way to do it?

PS: I'm running on Ubuntu 10.04
