Comment 23 for bug 240916

Thank you Cefn, excellent work around.

I have just installed 9.10 having previously used Gutsy, Hardy, Intrepid and Jaunty and having to replace my trusty iiyama vision master pro 512 with a Sony Multiscan 520GS and swapping out my Belkin Omniview E-series KVM for the Avocent Switchview 100 KVM; which has sound. Kept the FX5200 graphics card. Somewhere along the line I lost control of the monitor refresh rate.

I found the tech specs for my Sony Multiscan 520GS i.e. max resolution of 1600 x 1200 @75Hz etc.

gtf to generate the modeline

and edited xorg.conf in a terminal (sudo nano /etc/X11/xorg.conf):

Section "Monitor"
        Identifier "Sony CPD-520GS"
        HorizSync 30-96
        VertRefresh 48-160
        Modeline "1600x1200_75.00" 205.99 1600 1720 1896 2192 1200 1201 1204$
EndSection

Section "Screen"
        Identifier "Default Screen"
        Device "Default Device"
        Monitor "Sony CPD-520GS"
        DefaultDepth 24
        SubSection "Display"
                Depth 24
                Modes "1600x1200_75.00"
        EndSubSection
EndSection

Section "Module"
        Load "glx"
EndSection

Section "Device"
        Identifier "Default Device"
        Driver "nvidia"
        Option "NoLogo" "True"
EndSection

NOW at last I have control!

It shouldn't be like this.

The only minor wrinkle is that I can't get the max resolution.

The best I can do is 1400 x 1050 @ 70Hz but at least it's workable i.e. the I have control and the screen doesn't wobble any more.

Failure to get the max res may be down to the KVM switch but having spent hours this morning I'm not about to put the monitor directly onto the pc to test this - I might do it later.

NB. 1400 x 1050 @ 75Hz doesn't work and 1400 x 1050 @ 85Hz doesn't work, none of the 4:3 aspect ratio 1600 x 1200's work i.e. very strange distorted and dulled or absent image which luckily reverts back to the previous setting after a short while to give me the chance of another attempt.

Thank you.
