I did sudo apt-get remove nvidia-glx-legacy Then I installed restricted manager and I used it to enable NVIDIA propr driver. I rebooted. I got empty screen so I shut down kdm via /etc/init.d/kdm stop. Then I tried to "startx" and I got "API mismatch: NVIDIA kernel module version 1.0.7184, and X module version is 1.0.9631", so I looked into /lib/linux-restricted-modules and I found ".nvidia_new_installed" file. I removed that file and tried startx again. X Window started with correct acceleration!
Then I logged into my user account and while the display was 1920x1440 the refresh rate was very poor. Kubuntu configuration revealed I run at 56 Hz and the only other option was 50 Hz. After some experimentation I found that after switching to 50 Hz the monitor appears flicker-free. Somehow, although KDE KControl says that it runs at 50Hz it actually runs at 75 Hz. Thank you for your help. I still believe that this is an error because a novice would hardly be able to resolve this. -- 2.6.20-16-generic cannot modprobe nvidia-glx https://bugs.launchpad.net/bugs/119471 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
