External monitor

Post#1 by Andreshko » 13 Feb 2012, 21:24

Hi everybody,
I have an HP mini 2133 netbooka with a small 10" display.
I have attached an external monitor 21" to the VGA output of my netbook.
The monitor is not recognized.
The output of "xrandr" command is:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 600, maximum 1024 x 600
default connected 1024x600+0+0 0mm x 0mm
1024x600 60.0*
1024x576 60.0
1024x512 60.0
800x600 60.0 56.0
720x576 60.0
856x480 60.0
848x480 60.0
800x480 60.0
720x480 60.0
640x480 60.0

Any help is highly appreciated!

First thoughts ... boot with the monitor plugged in and look at your /var/log/Xorg.0.log file for clues. This means after booting up open a konsole and enter the following code:

Code: Select all

cat /var/log/Xorg.0.log
After that try to see if you can get a modes line for your monitor:

Code: Select all

gtf 1024x768 -v -x
This would be the information that you require to paste into your xorg.conf file but .......... It looks to me like your problem is getting the VGA to be recognized int he first place. Please give the information for:
lscpi|grep VGA

Posted after 2 hours 59 minutes 46 seconds:
Your notebook uses the chrome 9 graphics chip. Please see this thread to see if it will work for recognizing your vga.

Wear your underpants on the outside and put on a cape.
