Unity Desktop Environment nonreponsive with GeForce 7300 LE and driver 270.41.19
The problem is the system freezes when I attempt to run the Unity DE. Mouse clicks have no effect, and the conky system monitor does not seem to update. Other desktop environments not requiring 3D work OK.
1. I installed the nVidia driver using NVIDIA-Linux-x86_64-270.41.19.run. Installing the nvidia-current driver the normal "Ubuntu" way, using synaptic and jocky-gtk ("Additional drivers" gui program) gives similar results, but with an earlier driver version (270.41.06).
2. Installing driver "nvidia-173" (173.14.30) using synaptic and jockey-gtk also gives a nonresponsive system.
3. Installing 173.14.30 from NVIDIA-Linux-x86_64-173.14.30-pkg2.run gives a system that can run Unity, albeit very, very slowly. Too slowly to be useful, IMHO. The test program "glxgears" runs very slowly and jerkily. With the 270.41.19 driver, glxgears seems to run fine (frame rate ~1970 FPS), except conky reports cpu 0 at 52% and cpu1 at 100%.
4. Some sources say the problem is with Compiz. I can see that Compiz is running in my frozen conky process monitor with driver 270.41.19. I'm not sure how to kill it and still run Unity.
5. I ran the script nvidia-bug-report.sh after running startx -- -logverbose 6.
6. The script that is used test if the system can run Unity gives a false positive result:
