Screen Res. with Etch Installation


Hello,

Not exactly a newbie, but I'm not that experienced with Linux (a demi-newbie?)
I had Sarge running on my old desktop pc and everything was fine but now I've installed Etch I cannot get my screen res above 640x480.
With Sarge, all I had to do was add the resolutions into the XFree86Config file and reboot.
On etch, the config file is different. I've made the changes to what I think it should be, but no joy.

The relevant parts of the xorg.conf is shown below. I've read that my monitor, a FPD1500, does not transmit its configuration correctly so you need to explicitly set it up.
If anyone has any ideas, then please let me know.

Thanks & Regards
Glenn

I think it should be
Modes "1024x768/60Hz"
to correspond to your modeline.
You may also want "fglrx" instead of "ati" if you have it.

I would just change it to this..

Code:
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies Inc 3D Rage LT Pro AGP-133"
Monitor "FPD1500"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600"  "640x480"
EndSubSection

or if you really need to use that modeline..


Code:
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies Inc 3D Rage LT Pro AGP-133"
Monitor "FPD1500"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768/60Hz" "800x600"  "640x480"
EndSubSection

The solutions given might be correct. If not, check /var/log/Xorg.0.log to see why a certain resolution is selected or not.

Secondly, you don't have to reboot! That is a waste of time if you are testing.

Either press crtl-alt-bksp, or open a tty window with ctrl-f1. Log in as root, and say:

/etc/init.d/kdm stop

and then:

/etc/init.d/kdm start


If you use gnome, substitute gdm for kdm.

Don't use the official ATI fglrx driver! Stick to the out-of-box open source driver. Ati's official drivers only support newer cards (radeon 9200 and above).
