Default Re: Asus V9400-X 64M in 1600x1200

Hi again,

It seems like I am not quite done with the setup of my V9400-X... my display show that it is running in 1600x1200@ 59Hz and the display is not as rock-stable as I have come to expect using DVI for many years now. I have found the following link: http://suif.stanford.edu/~csapuntz/rv280-linux-dvi.html - actually about an ATI GPU, but this could be a similar issue. I would like to try to use reduced blanking timings, but the nvidia driver ignores my setup in xorg.conf. This is an extract from Xorg.0.log generated by "startx -- -logverbose 6":

(II) NVIDIA(0): Reduced Blanking enabled to bring Pixel Clock in range.


So the nvidia driver clearly know about "reduced blanking" - but I would like to try to reduce it further. How do I do that ?

And what is the difference between the two reported max pixel clocks:

(--) NVIDIA(0): HP LP2065 (DFP-0): 135.0 MHz maximum pixel clock

and

(--) NVIDIA(0): EDID maximum pixel clock : 170.0 MHz

The 135MHz limit is the limit normally reported in Xorg.0.log (without -logverbose).

Thanks in advance


PS: I have tried to use the driver on SuSE 10.1 (installing via YaST2 using the nVidia instructions on top of a fully updated 10.1). While my SuSE 9.2 has been solid as a rock for the past year, the SuSE 10.1 has crashed several times within a few hours. Common to these crashes is that the mouse cursor disappear from the screen. Are there any known stability issues for the nvidia driver on SuSE 10.1 ?
