How do I correctly set up refresh rate?

[kamenk]

Hi guys, I solved my previous problem and installed the Nvidia drivers, now I'm back to bother you. ;-p

I just switched to a higher resolution and noticed (or think I noticed) a drop in the refresh rate. This made me look in /var/log/XFree86.0.log (this is Slackware 9.0 with the lates Nvidia drivers). At the bottom of the post is what I found. It seems I have not corectly configured my refresh rate in /etc/X11/XF86Config. Now, what should the right values be? Do you guys need more info to answer that question - I can post my entire config and/or log file.

I have an additional question. When I switch back from 1280x1024 to 1152x864 I get a screen that is bigger that the display and can be scrolled with the mouse. This is extremely annoying, I want my screen to fit the monitor, why is it happening? And of course, how do I fix it?

XFree86 4.3.0 (is that your version?) has a compiled-in list of VESA modes (resolution + refresh rate) that it tries. If you don't specify any modelines, it chooses the one from that list that the monitor and driver both support (the monitor support is determined from the HorizSync and VertRefresh ranges in your Monitor section), with the highest refresh rate.

If you need to use a higher refresh rate, check that your HorizSync and VertRefresh lines match up with your monitor's specs.

Also consider getting rid of any mode lines you have in there, since three of them are wrong, and there's a precompiled list of available ones anyway.

If you want to force something, use the XFree86 4.3.0 gtf program to generate a modeline.

hello,
you should get the modelines for you moniter and put them in in /etc/X11/XF86Config

[kamenk]

I used gtf and put the result in my XF86Config, then referenced the string in "". Now X won't start, saying "no screen was found". I deleted the offending entries and so I am now able to post here.

Can somebody please give me an example of such a modeline which works?

Btw, is the performance of GNOME 2.2 supposed to suck so much? Somehow I don't like it. Moving and resizing windows is a pain, and if i move the rxvt window too fast it starts displaying all the positions in between (sorry, English is not my native language). Also, when I move XMMS around the screen it moves slowly and CPU usage jumps to 100%. Not sure if this is related to the graphic driver, though.

I have a Riva TNT2 Ultra with 32 MB RAM; RAM is 256 MB SD; CPU - PIII Coppermine @ 600 MHz. Maybe it's not the driver's fault and just my old hardware? Maybe I'm better off with Blackbox?
