Reolution

Ok I am having troubles changing my resolutions, I have read some guides on this, I just dont know what I am doing wrong? below is my xf86config.

Section "Monitor"
HorizSync 31-48
Identifier "Monitor[0]"
ModelName "1280x1024@60HZ"
Option "DPMS"
Modeline "1280x1024" 65 1024 1048 1184 1344 768 771 777 806 -hsync -vsync

Modeline "1280x1024" 108 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync

Modeline "1280x768" 108 1280 1328 1440 1688 768 771 777 806 +hsync -vsync

VendorName "--> VESA"
VertRefresh 50-60
UseModes "Modes[0]"
EndSection

Section "Modes"
Identifier "Modes[0]"
Modeline "1280x1024" 62.35 1024 1056 1184 1312 768 772 776 792 -HSync -VSync
EndSection
Section "Screen"
DefaultDepth 16
SubSection "Display"
Depth 15
Modes "1280x1024"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 32
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 8
Modes "1024x768"
EndSubSection
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
EndSection

I'm wanting it to run at 1280x1024, I know my monitor and all can handle it, cause that is what I run in windows. I dont know what resolution it is running at now, but i would guess 1024x768. Not sure if it matters but i am running SUSE, KDE

Thanks
any problems?

You say xf86config? The file you want to check it /etc/X11/XF86Config-4. You should have a section which looks like this:

Code:

Section "Screen"
    Identifier  "Screen 1"
    Device      "** SiS (generic)                      [sis]"
    Monitor     "My Monitor"
    DefaultDepth 24

    Subsection "Display"
        Depth       8
        Modes       "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes       "1024x768" "800x600" "640x480" "320x240"
        ViewPort    0 0
    EndSubsection
EndSection

What it means is this:

Code:

Section "Screen"
    Identifier  "Screen 1"
    Device      "** SiS (generic)                      [sis]"
    Monitor     "My Monitor"
    DefaultDepth 24

Screen sets up the screen for X. The Identifier is arbitrary, and the Device and Monitor are the identifiers for the graphics card and monitor defined elsewhere in the config file. The DefaultDepth is obviously the Default Depth, in this case 24bits.

Code:

    Subsection "Display"
        Depth       24
        Modes       "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection

These sections specify which resolutions are available with each depth. The first one is the default, so you will want sections like this:

Code:

    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection

Then X should start in 1280x1024 by default. If you want to check, then take a screenshot with KSnapshot, open it in the GIMP, or another picture editor, and put the cursor to the lower right and read off the co-ordinates. There's probably an easier way to tell, but I can't think of one right now.
Hope this helps

My xf86config looks alot different? I didnt have XF86Config-4 all I have is XF86Config, XF86Config.saxsave, and XF86Config.YaST2save. They are all exactly the same. Should I just change mine to look like yours? Below is what my entire video section looks like...

Section "Modes"
Identifier "Modes[0]"
Modeline "1280x1024" 62.35 1024 1056 1184 1312 768 772 776 792 -HSync -VSync
EndSection

Section "Device"
BoardName "GeForce4 Ti 4200"
BusID "1:0:0"
Driver "nvidia"
Identifier "Device[0]"
VendorName "NVidia"
EndSection

Section "Screen"
DefaultDepth 16
SubSection "Display"
Depth 15
Modes "1280x1024"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 32
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 8
Modes "1024x768"
EndSubSection
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
EndSection

Right, here's your problem:

Code:

Section "Screen"
DefaultDepth 16
SubSection "Display"
Depth 15
Modes "1280x1024"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768"
EndSubSection

Your default depth is 16bpp. The 1280x1024 mode is only specified for a depth of 15bpp. If your graphics card can handle it, I would recommend a depth of 24bpp, which you will get by changing DefaultDepth to 24. Regardless of this, if you want the resolution changed for all video modes, make that section look like this:

Code:

SubSection "Display"
Depth 15
Modes "1280x1024" "1024x768"
EndSubSection
SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768"
EndSubSection
SubSection "Display"
Depth 32
Modes "1280x1024" "1024x768"
EndSubSection
SubSection "Display"
Depth 8
Modes "1280x1024" "1024x768"
EndSubSection

So that each SubSection contains the extra resolution. That should fix things.

Why do you try to configure it manually? Use sax2

garf12 · 03-12-2004, 05:51 AM

When I try doing it with sax2 i get "The selected resolutiong doesnt fit into the sync-ranges of the monitor. Please prove if the currently selected monitor. Please prove if the currently selected monitor model is correct or select a lower resolution than: 1280x1024"

I also tried what guygriffiths said, but I am still getting 1024x768
