I have an Asus eeepc 1101ha netbook.
I installed recently Ubuntu 12.04 LTS.
The netbook has the Poulsbo graphics chip. I am using the PSB-GFX driver, having followed these instructions
The netbook generally works well.
The problem: When I connect an external monitor, it is not detected.
The "displays" window shows only the internal monitor.
xrandr as well.
disper as well.
I have no /etc/X11/xorg.conf file.
Native resolution of the internal monitor is 1366x768.
Native resolution of the external monitor is 1024x768.
user@netbook ~ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation System Controller Hub (SCH Poulsbo) Graphics Controller (rev 07)
I tried to logout and login again having the external monitor connected, in order to see what happens. No difference.
I tried to reboot having the external monitor connected. The netbook starts in 1024x768 resolution (leaving a black stripe on the right of its internal screen!!) and duplicating the display and showing it correctly in the external monitor. (If I try to suspend, I lose the external after waking up, but this is another issue.)
So, the problem is in the driver, right? I actually don't have a driver choice for this netbook. Is there anything I can do?
Thanks in advance!
