knoppix resolution and refresh rate problem
hello,
iv installed knoppix to my hard drive, and recently it was all working fine, until i reboot and the resolution was at 1024x768 (which it was before) but the refresh rate is 85 even though it seems more like 60. i can't change the resolution to anything else, in the display configuration tool there is only 1 drop down option which is 1024 x 768 and refresh rate there is only one option whish is 85 (but the screen refresh rate is more like 60) in windows its 1152x864 running at refresh rate 75 nvidia geforce fx 5200 iv tried cheat sheets vsync=70 hsync=70 screen=1024x768 (also tried 1152x864 doesnt work) depth=24 (however the avaialble depths to me in windows are 16 or 32 now even at 1024x768 it wont go to 75 refresh (it hurts my eyes at 60) is there any xfreeF86 tools i can use to diagnose and fix this ? or to correct it ? on linux boot up (its knoppix harddrive version) it detects NVidia GeForce FX5200 and displays 1024x768 800x600 640x480 when i booted up as screen=800x600 it said NVidia GeForce FX5200 800x600 640x480 is there anythign else i can try, is there anything i can do with the xfree config files in the etc/x11/ directory theres about 4/5 different files some with a -4 at the end i dont no what that means |
You can manually change it. Edit either you xorg.conf or xfree86.conf. Depending on which X window system knoppix uses (i don't remember). The file is very easy to read it's divided into sections. Scroll down till you see the part of vertical and horizton refresh rates. Also xorgconfig or xfree86config.
There is the section you need: Code:
# USER MANUAL FOR THE CORRECT NUMBERS. The section for resolutions is a bit farther down. |
Nope I can't see anything like that. iv checked all files
i have xf86config xf86config-4 xf86config-in xf86config.in xftconfig is there anyway i can have linux rebuild my xf86config files, i.e. erase them then recreate them ?? and im running kde btw edited: icant even edit any of the above files, it wont let me safe, ive tried as root as well, just says files cannot be written to check permission etc. |
hmm. That's strange. Your x config file should be in /etc/X11.

you can do this changws in file /etc/X11/XF86Config-4
