Radeon 7800: Resolution wont go higher then 1024x768

[JesterDev]

As the topic says, I can't get any higher then that. Normally I can get 1600x1200 so I know my card supports it. I searched the forums but found no answers. Running the kernal that comes with fedora.

It's probably the /etc/X11/XF86Config monitor setup. When I installed FC1 the X setup gave me an unprobed monitor with sync and refresh values that max out at 1024x768. Here is what I changed mine to:

Section "Monitor"
Identifier "Monitor0"
VendorName "Dell"
ModelName "Dell"
HorizSync 30.0 - 85.0
VertRefresh 50.0 - 130.0
Option "dpms"
EndSection

Please note...playing with these can be dangerous! :twisted:

Hope that helps,

here is mine (/etc/X11/XF86Config(-4)):

VertRefresh 60 - 85
Option "DPMS"


check your screens technical details for information about sync values.
