disable underscan by default

[selberbauer]

Hi, i got an ATI Graphic card connected to a Monitor over a HDMI <-> DVI Cable

Because of the intelligent ATI driver i get after every boot a small picture with a large border around.

The solution is to type in "xrandr --output DVI-0 --set underscan off" this solves the problem but it sucks to type it every time in the console after reboot

Now i want to disable underscan by default.
How do i do this?

1.) should i write a script and add this script to runlevel default via rc-update?
(if yes how do i do this?)

2.) Put the xrandr command in a xorg config
(In which xorg config?)

Best Regards

I've been meaning to look into this for my own setup.

This is where it was changed. You could try patching the kernel driver and see if that restores the original functionality.

(copied already in a file but then?)

If you use KDE, you can put the xrandr call in /usr/share/config/kdm/Xsetup.

Must be something equivalent for other environments.

Now that I'm actually at home and remember that I wanted to look into this (I've spaced it off for a while now), I've found some good news.

This should be reverted sometime soon-ish upstream.
