Monitor refresh rate

Valkyrie_of_valhalla · 02-24-2007, 01:21 PM

The default nvidia driver install program edits the xorg.conf so that it can only reach 60Hz. I edited it manually, and it works fine for root, it shows 60 and 70Hz in KDE's control center, but as a regular user, I get only about 6 values between 50 and 60Hz...
I don't get it. Why don't I have the same values for both users? What am I doing wrong?
Thanks for reading. Any info/suggestion is welcomed.

PS here is [part of] xorg.conf:

Tried adding a new user too... still no luck...
And with the user, at 1024x768 and 60Hz, I get these weird vertical lines on the screen, but only with this frequency... The lines aren't very obvious... It's like when you run a Dos app with a modern windoze (eg borland pascal/c). With root, same resolution, 70Hz, it looks ok...

I'm really out of ideas... I need at least a hint where to start. Any ideas?

Try lowering the default depth from 24 to 16. That might make any difference but I'd give it a shot

hmm, thanks, I'll try that too.
An interesting thing is that if I use the nvidia config utility, it seems to modify the refresh rate (my eyes hurt less, the only way I can tell), but in the settings in the control center on KDE, and also in the settings pannel on xfce, it still displays the old frequency...
