I'm having the same problem, although my screen is in interlace mode. According to nvidia-settings it is in 1024x768, 43Hz interlaced mode (or it might have been 42Hz). According to xrandr, 1024x768, 57Hz:
SZ: Pixels Physical Refresh *0 1024 x 768 ( 346mm x 260mm ) 50 53 54 55 56 *57 1 800 x 600 ( 270mm x 203mm ) 51 62 63 64 65 66 67 2 640 x 480 ( 216mm x 162mm ) 52 73 74 75 76 3 960 x 600 ( 325mm x 203mm ) 58 4 896 x 672 ( 303mm x 227mm ) 59 (...etc..) I am using the nvidia driver, gdm, kde, and kubuntu 7.04. kernel: 2.6.20-14-generic, x86_64 Unfortunately, I cannot test the nv driver as it does not support my GeForce 7800 GT. One thing I should mention is that I have my system set up in a multiseat configuration. When it wasn't, I was able to use nvidia- settings to change the refresh to 85Hz, which lasted until reboot. But now, because I'm running two Xgl sessions on top, I cannot use nvidia- settings (that's why I can't check whether it was 42 or 43 Hz.) Here is my ~/.kde/share/config/displayconfigrc file. Notice that it has the correct refresh value listed: [General] targetgamma=2.0 [Screen0] dpmsEnabled=off dpmsSeconds=2700 height=768 reflectX=0 reflectY=0 refresh=85 rotate=0 width=1024 -- kde changes screen refresh rate of nvidia card https://bugs.launchpad.net/bugs/89640 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
