[Bug 89640] Re: kde changes screen refresh rate of nvidia card

[Jeffry Johnston]

I'm having the same problem, although my screen is in interlace mode.
According to nvidia-settings it is in 1024x768, 43Hz interlaced mode (or
it might have been 42Hz).  According to xrandr, 1024x768, 57Hz:

 SZ:    Pixels          Physical       Refresh
*0   1024 x 768    ( 346mm x 260mm )   50   53   54   55   56  *57  
 1    800 x 600    ( 270mm x 203mm )   51   62   63   64   65   66   67  
 2    640 x 480    ( 216mm x 162mm )   52   73   74   75   76  
 3    960 x 600    ( 325mm x 203mm )   58  
 4    896 x 672    ( 303mm x 227mm )   59  
(...etc..)

I am using the nvidia driver, gdm, kde, and kubuntu 7.04.  kernel:
2.6.20-14-generic, x86_64

Unfortunately, I cannot test the nv driver as it does not support my
GeForce 7800 GT.

One thing I should mention is that I have my system set up in a
multiseat configuration.  When it wasn't, I was able to use nvidia-
settings to change the refresh to 85Hz, which lasted until reboot.  But
now, because I'm running two Xgl sessions on top, I cannot use nvidia-
settings (that's why I can't check whether it was 42 or 43 Hz.)

Here is my ~/.kde/share/config/displayconfigrc file.  Notice that it has the correct refresh value listed:
[General]
targetgamma=2.0

[Screen0]
dpmsEnabled=off
dpmsSeconds=2700
height=768
reflectX=0
reflectY=0
refresh=85
rotate=0
width=1024
