I followed these ( http://blog.mypapit.net/2011/05/howto-mining-bitcoin-in-ubuntu-using-opencl-py.html ) directions without any error and now the launch bar for unity is no longer displayed. Can someone help?

unity --reset results in the following error

unity-panel-service: no process found
Backend     : gconf

use unity --reset –  Uri Herrera Jul 4 '11 at 1:00
    
Did you make any changes to your graphics drivers when updating your system? Is there any interesting errors related to DRI or GLX in /var/log/Xorg.0.log? Does the X server start up properly when you aren't running the OpenCL program? –  James Henstridge Jul 4 '11 at 6:03
    
I haven't made any changes to the graphics drivers. Unsure how to check for errors, although I searched the log file and it came up empty. How can I check to see if X server starts up properly? –  Jeb Jul 4 '11 at 9:00

The output from your unity --reset run indicates that your X server isn't advertising the GLX extension (one of the extensions exposing the OpenGL API). My hypothesis is that the OpenCL application is blocking access to the GPU for the X server. If that is the case, I would expect to see some note about that in the X server log file. –  James Henstridge Jul 4 '11 at 9:41
    
Well I was messing around more with it and thought I'd reinstall all the xserver files from synaptics which was a bad idea. So instead of trying to fix the computer from not booting I just reinstalled 10.10 and upgraded. Thanks for the help! –  Jeb Jul 5 '11 at 7:30

compiz --replace will probably fix that.
