I have resolved this situation. Belows are the step. It's just all things that I did. To tell the truth, I don't know which step is necessary or unnecessary and what is right or wrong. However, I hope my experiences can help other users.
0. My laptop is Lenovo T61 with nvidia Quadro NVS 140 M 0. I updated from hardy to intrepid using "update-manager -d" 0. I encountered the error message that xorg server can't parse config file. 0. I restarted with default configuration and did some instructions that I found on the Internet, but they aren't work well. 1. Boot with Xorg server default configuration first. 2. Remove all things that are related with nvidia in the Synaptic. 3. Reboot again 4. Install nvidia-things except nvidia-xconfig package. nvidia-glx-177 nvidia-*-modaliases nvidia-kernel nvidia-kernel-common nvidia-177-kernel-source nvidia-settings 5. Reboot again 6. Run sudo nvidia-xconfig.( It works well even though I didn't installed nvidia-xconfig package. I'm getting insane? :-) ) 7. Restart X server. It works well now with nvidia driver 177. -- Failed to load module "nvidia" https://bugs.launchpad.net/bugs/273801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
