Nvidia 8756 and refresh problem

3 Attachment(s)

since i've installed ubuntu 5.10 on my LCD screen, a SAMTRON 72v, i've got problems with refresh... i've set the VertRefresh at 56 ~ 75 Hz and horizsync at 31 ~ 81 kHz, like wrotten on monitor guide...
My screen resolution is: 1280 x 1024@75Hz, but on the guide table it is written that the optimal resolution is 1280 x 1024@60Hz
I send you my Xorg.0.log and my xorg.conf
How can i set the refresh at 60hz? In the gnome menu i've only 75hz option...
I've read this post: http://www.nvnews.net/vbulletin/show...3&postcount=18
and i've added this line to Monitor section

Code:

Modeline "1280x1024_60" 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync

But it doesn't works...
Have i to install again the drivers?
Thanks
Bye

Re: Nvidia 8756 and refresh problem

In your X conf change this

Code:

SubSection     "Display"

        Depth       24

        Modes      "1280x1024" "1024x768" "800x600" "640x480"

EndSubSection

Code:

SubSection     "Display"

        Depth       24

        Modes      "1280x1024_60" "1024x768_60" "800x600" "640x480"

EndSubSection

Re: Nvidia 8756 and refresh problem

i've done what you said, but at 60hz, the images on the screen are worst, they are more choppy than 75hz mode.
What can i do?
I continue to have the choppy problem.
Sorry for my english, but i'm italian.

Re: Nvidia 8756 and refresh problem

I know what you mean about low refresh rates. The screen flickers. Very annoying. I'm using 85Hz at the moment - the most I can do. I suggest leaving the settings at the most your screen can handle, don't go over it.

Re: Nvidia 8756 and refresh problem

ok thanks, the most is 75hz, my actual configuration

Re: Nvidia 8756 and refresh problem

You will need to look at your X log to see what is going on. It's in /var/log/. if it still gives you grief attach a nvidia bug report here.

Re: Nvidia 8756 and refresh problem

I'm unsure but you could try commented out these lines from your X conf.

Code:

Option         "UseEdidFreqs"         "FALSE"

Option         "UseEDID"              "FALSE"

Option         "ModeValidation"       "NoEdidModes"

In the begining, I have trouble with nvidia&FC5 , screen black. Then I installed the nvidia8756 driver, but it can't startx X. then I removed /etc/X11/xorg.conf, now it works, X started!

Simply put a # character at the start of the line. It turns the line into a comment and not something for the computer to process.
