Screen Resolution 800x600 with black borders

JoSch1337 · 11-08-2006, 02:55 AM

Hi!

The topic title may suggest, that I'm having problems with my graphics card and that I can not set my resoltion to i.e. 1024x768 and that I'm stuck to 800x600 with a black border on my tft.

Actually it's the other way round.
I have an ASUS Laptop with integrated ATI graphics an everything is working fine. But if I change the resolution to something lower than my native 1024x768 the image is stretched across the entire screen.
How do I change my configuration, that changing the resolution does not stretch the image but produces a black border around it, so that the image is still sharp?
On windows there's a setting in the ati driver called "stretch image to panel size" on intel chips it's called "panel fitting". This can be activated and deactivated in windows. How do I do it in linux? I don't find an entry in xorg.conf.

Thanks for your help! JoSch

Well, try to use xvidtune to make a proper modeline. Maybe it will do the job.

Okay, I tried xvidtune but for some reason there's no effect if I change anything and then click apply or test. Do you know why?

Give me details about your distro, xserver, and give the config file for xserver.

JoSch1337 · 11-10-2006, 12:51 AM

Okay, I'm using Ubuntu 6.10 with latest xserver I think. Here is my config. Everything has to be default.

Code:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

On Ubuntu try to put xvidtune to /etc/sudoers and run it with root privileges.

JoSch1337 · 11-10-2006, 01:43 PM

I now got the solution!
I had to use the fglrx driver and add the Option

Code:

Option "Centermode" "On"

to my Device section. It now works the way I want it to.
