I had similar problems to the ones that other people are having. For me they were related to having installed the NVidia driver using the NVidia installer. I solved them by uninstalling using the Nvidia installer and then reinstalling the ubuntu packages (nvidia-glx, linux-restricted- modules-2.6.20-14-generic) and then unloading the nvidia driver (the wrong one had been loaded somehow. And a reboot would have worked too). So overall it looks like the below on console. It must be done from outside X or the module unload will fail.
$ sudo invoke-rc.d gdm stop $ sudo bash NVIDIA-Linux-x86-1.0-9631-pkg1.run --uninstall $ sudo aptitude reinstall linux-restricted-modules-2.6.20-14-generic nvidia-glx $ sudo rmmod nvidia $ sudo invoke-rc.d gdm start I hope this helps someone. -Arthur -- MASTER: Request for new-legacy nvidia drivers (9631) https://bugs.launchpad.net/bugs/96430 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
