External monitor not detected (Asus eeepc netbook, Ubuntu 12.04)
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.
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!
Many laptops and netbooks do not activate the external VGA port. Usually there is a hot key combination defined in the BIOS that activates the port.
I have a HP netbook, and to use the external port, I have to hit a Fn key plus F4 key. Have a look at the documentation for the hardware to see if you have such a combination.
For Asus eeepc 1101ha, the key combination is Fn+F8. But sadly, it does not do anything in Ubuntu 12.04. I just tried. )-:
You probably need to get the external monitor detected. Here are a couple of links that may give you some help.
Try the command 'xrandr' in a konsole. See if you get something like 'VGA1 disconnected' If you do, then it is a case of getting the monitor detected. On modern xorg systems there are config files for the monitors. Its been a while since I ran Ubuntu, so I can not tell you the names of the files. Hopefully the above links will get your external monitor going.
