Hi all,

I'm having a strange problem with my xserver/graphicscard/monitor that I hope someone here will be able to help me with... probably it's just some little tweak somewhere that I have overlooked...

To make a long story short, the problem is that I can get my xserver to start only in the highest (1600x1200) or lowest (640x480) mode... nothing in between.
The specifications of monitor and graphics card in my XF86Config-4 read like this:

(...)
Section "Monitor"
#DisplaySize 320 240 # mm
Identifier "CPQMonitor"
VendorName "CPQ"
ModelName "COMPAQ V700"
HorizSync 30-85
VertRefresh 50-160
EndSection

Section "Device"
Identifier "S3VideoCard"
Driver "savage"
VendorName "S3 Inc."
BoardName "VT8375 [ProSavage8 KM266/KL266]"
BusID "PCI:01:00:0"
EndSection
(...)

Now, when I do NOT specify any "Modes" in section "Screen", the xserver starts up correctly, but with the highest possible mode. The log then reads like this:

(...)

As this is not what I want, I proceed to specify "Modes":

(...)
Section "Screen"
Identifier "Default Screen"
Device "S3VideoCard"
Monitor "CPQMonitor"
DefaultDepth 16
(...)
SubSection "Display"
Depth 16
Modes "1280x960" "1024x768" "800x600" "640x480"
EndSubSection
(...)
EndSection
(...)

Normally, I would expect the xserver to start up in 1280x960 now, but what happens instead is that as soon as I enter "startx" the screen turns black and goes to "sleep". I have to Alt-Strg-Fx into another console then and kill the x-process.

The funny thing is that when I remove the "HorizSync (...)" line in the monitor section, the xserver falls back to the default "HorizSync 28-33" and fires up the "640x480" mode in 16-bit color.

And, yes, both the horizontal sync and the vertical refresh rates are correct, i.e. they conform to the specifications.

After countless hours trying to figure out the solution I'm clueless now.
Anybody? Pretty please?

TIA,

Interestingly, after many "trials and errors", I found that I can achieve 800x600 by adding the following lines:

HorizSync 50 # instead of HorizSync 30-85
(...)
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection

Please note that the following modifications did NOT work:

HorizSync 30-40
HorizSync 60
HorizSync 30-50

I had also tried to add various modelines for 800x600, even the default ones that I found in the xserver-log, without success.

I am dumbfounded!!!

H Freq/ V Freq: 30-85 / 50-160

works for me...
