Hi all,
changeing from a 19" CRT (1024 x 768 @85hz) to a 17" TFT/LCD which I want to run at 1280 x 1024 except the screen res won't change. I can select the new res but the display does not change (it does show the keep new or use old prompt over the the original 1024 x 768)
When looking in the config it still shows my old monitor.
Any help appreciated.
Rod

This is a point where it is not as simple and straightforward as you would like.
You could reconfigure xserver (sudo dpkg-reconfigure -phigh xserver-xorg ) but that makes you install the driver again and that's overkill.
this should do it if you're in gnome. Change accordingly if you use KDE
sudo gedit /etc/X11/xorg.conf
Study the file and you will see a section like this
in the beginning of the line. This is for a 17 inch LCD
The +0+0 is there only if you have a 0 added in the beginning I think, so you should adjust accordingly
//edit//
I only have settings for 24 bit color depth
there may be settings for 1 (yes!), 8, 15 and 16 bits as well

Now that's interesting, I used "gksu gedit /etc/ X11/xorg.conf & when I edited out resolutions below 800 x 600 a while back and it worked in Gnome.
Re-installing the vidio driver is simple so I might try that. Do I need to remove it and reinstall or just install over the top of the current driver?
