After 4 hours of LLVMpipe lagginess, I couldn't take it anymore, soooo I started looking for a solution.
Startpage (Google proxy search engine) didn't help much -- found zillions of posts complaining about it, but that was about it.
Funny thing was, some (respected names) in these forums said, they couldn't see any difference in performance, between nVidia drivers and Nouveau. How could that be?!?!?
Then, it dawned on me. My debug script was reporting VMware, Inc. to be the OpenGL vendor. Hello
After pondering this for a while, I started thinking about "/etc/modprobe.d" et al. Seems like I
blacklisted Nouveau years ago. That couldn't be it, right? Otherwise, why is it working, albeit horrible slow, laggy, and consuming 100% CPU usage most of the time?
Sure enough! Even though I (myself) hadn't blacklisted Nouveau (or it had gone to null) there was a file in "/etc/modprobe.d" called "
nvidia-installer-disable-nouveau.conf".
I renamed that file, with a different extension, and restarted Saucy. Bingo!
Updated report...
Code:
Current Date/Time: Sun May 26 16:34:55 MST 2013
Distro Release: Ubuntu Saucy Salamander (development branch)
Kernel Release: Linux 3.10.0-031000rc2-generic
Gnome Release: GNOME Shell 3.9.1
Unity Release: unity 7.0.0
OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NV4B
OpenGL version string: 2.1 Mesa 9.2.0
w00t! No more LLVMpipe -- no more lagginess!
This box is flying now! I ran GTKPerf a few times, and the results/performance are indistinguishable from nVidia-304, now.
Makes me wonder how many 1000's of others are suffering from this Nouveau blacklist/VMware "problem".
