[ATI] Resolution Problems

Okay, so my monitor's native resolution is 1440x900 (19" 16:10) but for some reason xorg will only display at 1400x1050 (4:3) which makes my eyes very sad, and I was hoping someone here could help me get it to the right resolution.

xorg conf: http://pastebin.com/m717e1aa9

Oh and I have a radeon 3870.

Re: [ATI] Resolution Problems

It does so because your xorg.conf says your monitor can do it.
In the "Section "Monitor"" try to comment modes your monitor doesn't support or that you don't want to use, I would delete or comment every resolution except the native one (if you are using a tft which I guess you do).
Or you could give autodetection a try,

Re: [ATI] Resolution Problems

Under Section "Monitor", add Option "PreferredMode" "1440x900".

Section "Monitor"
     ...
     Option "PreferredMode" "1440x900"
EndSection

The problem is my monitor's native resolution isn't in there, and I don't know exactly how to make a new one. I have tried tweaking the 1400x1050 resolution but it doesn't work (probably doin it wrong.) I have heard also from a friend that it might be the VESA driver which I'd like to replace anyway but I can't seem to get the ATI driver loaded.

Under Section "Monitor", add Option "PreferredMode" "1440x900".

Section "Monitor"
     ...
     Option "PreferredMode" "1440x900"
EndSection

Thanks for the suggestion, but doesn't work when the proper mode isn't in there anyways.

Re: [ATI] Resolution Problems

Then try the following in /etc/X11/xorg.conf
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes "1440x900"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes "1440x900"
        EndSubSection
EndSection

Gawd, I _hate_ these new-fangled widescreens - give me 1280x1024 (or even better 1600x1200) any day!!
