Need Help On Desktop / Labtop Monitor Issues

[livinthailandos]

Hope someone out there can help me on this as I really haven't gotten an answer for this though. Should be something not to hard to figure out. Heres the deal

I have a Sony Vaio Labtop VGN-CR32 running Ubuntu 8.10, my screen is slight cracked so unable to use labtop fully, I went a bought a Acer X22S Desktop Monitor, I have hooked the monitor plug to labtop so that I can still use my labtop just not the screen, Sometimes I load in Gnome Desktop and the Screen will go Blank or black then come back then I'm unable to view my desktop for a sec or so, I wanted to use KDE also but the screen goes blank the comes back but its very fast ( see black screen see desktop non stop back and forth ) and i'm unable get anything done. any ideas on how to set this straight.

Hey, I'm sure you got this ironed out, since your post is two weeks old. But in case not, try this:

gksudo gedit /etc/X11/xorg.conf

Look for the section that says:

Section “Device”

Identifier “Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller”

Driver “i810″

BusID “PCI:0:2:0″

EndSection

Insert the code:

Option “MonitorLayout” “CRT,LFP”

Option “Clone” “true”

Option “DevicePresence” “true"

just above the "EndSection" line

Save the file and exit.

Press “Ctrl + Alt + Backspace” to restart Xorg.conf

That should do it.

Dear johnnynmonic

I would like to say that your advice helped but it didn't it did just the opposite, I now no longer can get any display at all. Some error can up and if when i try to use startx it won't start. I am using a knoppix cd to try to take the advice you gave me out so hopefully that will fix my problem. at least before I could log in to gnome now I just get a black screen with my log in name just using commands and I'm unable to edit x11/xorg.conf

Doh! So sorry. You can edit the xorg.conf with no x in nano (a command line text editor):

sudo nano /etc/X11/xorg.conf

and delete the change I suggested. So really truly sorry. I retire as xorg.conf troubleshooter on any machines but my own. Seriously, I feel really bad. I was sure that would work.

If you boot from Knoppix could you post the output of the command xrandr* when the external monitor is connected and switched on.

*type man xrandr from a terminal to see what it does first if you aren't sure, but don't worry it is perfectly safe:

DESCRIPTION
   Xrandr is used to set the size, orientation and/or reflection of the
   outputs for a screen. It can also set the screen size.

   If  invoked  without any option, it will dump the state of the outputs,
   showing the existing modes for each of them, with a '+' after the  pre-
   ferred mode and a '*' after the current mode.
