1. Make a backup of the file XF86Config. Open up a root terminal and type
Code:
cd /etc/X11/
cp XF86Config-4 XF86Config.backup
If you want to do this part with a GUI you can open up the root terminal and type "nautilus".
2. Open up text editor and look for the lines that begin with
and
It will be under section "monitor".
3. Change the "HorizSync" line to
and the "VertRefresh" line to
4. Scroll down to near the bottom of the file you will see a section called "Screen" it should look something like this
Code:
Section "Screen"
Identifier "Screen 1"
Device "Radeon 9600xt"
Monitor "My Monitor"
DefaultDepth 24
Subsection "Display"
Depth 8
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1400x1050" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
It won't look exactly like that since this is for my system and I suspect that you will have values in the 8 and 16 bit depth sections (unlike me where I only have filled in the 24 bit section). What you want to do is add "1280x1024" as the first resolution in each of the modes. Example:
Code:
Section "Screen"
Identifier "Screen 1"
Device "Radeon 9600xt"
Monitor "My Monitor"
DefaultDepth 24
Subsection "Display"
Depth 8
Modes [color=deeppink]"1280x1024"[/color] "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes [color=deeppink]"1280x1024"[/color] "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes [color=deeppink]"1280x1024[/color]" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
5. Save and edit. When you reboot you should boot into the new resolution.
