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.
