Question How can I set my screen to 800x600 after I modified frequencies ?


I found a way to change my monitor frequencies ( I posted a thread before ) , Linux frequencies were 69.1KHZ , 108HZ but You can't find 61HZ in display option and sax2 , So I edited xorg.conf and make it 37.9KZ , 61HZ Windows standard , But after I changed Linux freq to Windows standard ( 37.9KHZ , 61HZ ) The screen changed to 400x300 or something , It was very small but it got no black borders <--- thats what i wanted , and great low frequencies too , But how do I change 400x300 to 800x600 and keep low frequencies at the same time ? Will xorg does that ? And if it does , How to ?

*I'm using SuSE Linux 10.0 , I have sax2 , xorgconfig , But I don't really use xorgconfig , I hate it >:\ I use sax2 ! :P

*After I changed it to 37.9KHZ and 61HZ , Possible highest resolution will be 400x300...

Thanks for helping !

Hmm, this should be possible to set directly.
The only guess I have is to set DDC off in the xorg.conf

In the 'screen' section of your xorg.conf there should be several 'display' subsections. Find the one with the appropriate bit depth and change the frequencies in 'mode' here's the section of my xorg.conf so you can see what you're looking for.

Section "Screen"
Identifier "Screen 1"
Device "VESA Framebuffer"
Monitor "My Monitor"
DefaultDepth 24
SubSection "Display"
Depth 8
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 32
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

DDC is a tecnology with which the monitor gives the OS a list of capabilities and the
OS configures the Xserver according to this (OK, it's a gross explanation, but I'm at work now, LOL).

There's a lot more of settings that can be done, specially tyhe option MonitorLayour accepts lots of parameters (try "NONE,CRT"). I'm no expert, just have a little experience with weird settings, thus I can't ell you much more.

I used xrandr and got this :

SZ: Pixels Physical Refresh
0 1024 x 768 ( 321mm x 241mm ) 78 68 58
*1 800 x 600 ( 321mm x 241mm ) *108 98 88 78 68 58
2 768 x 576 ( 321mm x 241mm ) 108 98 88 78 68 58
3 640 x 480 ( 321mm x 241mm ) 128 118 108 98 88 78 68
4 832 x 624 ( 321mm x 241mm ) 75
5 640 x 512 ( 321mm x 241mm ) 60
6 720 x 400 ( 321mm x 241mm ) 85
7 640 x 400 ( 321mm x 241mm ) 85
8 576 x 432 ( 321mm x 241mm ) 75
9 640 x 350 ( 321mm x 241mm ) 85
10 512 x 384 ( 321mm x 241mm ) 85 75 70 60 87
11 416 x 312 ( 321mm x 241mm ) 75
12 400 x 300 ( 321mm x 241mm ) 85 75 72 60 56
13 320 x 240 ( 321mm x 241mm ) 85 75 73 60
14 320 x 200 ( 321mm x 241mm ) 85
15 320 x 175 ( 321mm x 241mm ) 85
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

After I changed refresh to 61HZ , It applied option 12 for me , And it stucked at 400x300 , no higher res, no lower res ( I can change refresh rate back and get bigger res , But that's not the prob , The prob is , option 1 has no 61 refresh , And I really want to use 61 because it got no black borders , And It's good to my eyes

Is that related to refresh rates ?
