External monitor not showing video and mouse pointer messed up

[Herby Pepper]

Pointer looks and work fine on laptop but when I connect external monitor it appears there as a shaking, square shape. Videos are not showing either.

my laptop hp 2133:
Graphic card: VIA Technologies, Inc. CN896/VN896/P4M900, Chrome 9 HC.
System: Lubuntu 12.04

I think it is graphic problem but can't find drivers for my card and system. I do have xserver-xorg-video-openchrome and disper installed.
I did not have that problem with Lubuntu 11.10.

Any ideas? thanks

I was able to get a nice pointer:


Since now Lubuntu/Ubuntu does not have xorg.conf file I generated it (1) and then modify it to look like the one from Debian website (2) (http://wiki.debian.org/InstallingDebianOn/HP/HP2133 )


1) generate xorg.conf:


press Ctrl+Alt+F1 (to switch to text terminal)


Login


sudo service lightdm stop (to stop desktop environment)


sudo xorg -configure (to configure xorg.conf, it will put the file in your home direction)


sudo cp home/username/xorg.conf.new /etc/X11/xorg.conf (in username put your user name) (to copy created file to the location that system will recognise and use it)


sudo service lightdm start (to start desktop environment)




2) modify xorg.conf:


go to http://wiki.debian.org/InstallingDebianOn/HP/HP2133 in section Resources Attachments there is xorg.conf file contents, select and copy it. (Ctrl+C copy selected)


Open terminal


sudo leafpad /etc/X11/xorg.conf (to open xorg.conf for modification)


Ctrl+A (to select all)


Delate (to delele selected)


Ctrl+V (to past copied earlier file)


Save and close file.


Restart computer.
