Recently when I restarted my dual boot Ubuntu (windows 7 and Ubuntu 12.10), all I can see is just my desktop, no dash, no launcher or any topbars. Here is the output of usr/lib/nux/unity_support_test -p:



 libGL error: failed to load driver: swrast

 libGL error: Try again with LIBGL_DEBUG=verbose for more details.

 OpenGL vendor string:   ATI Technologies Inc.

 OpenGL renderer string: ATI Mobility Radeon HD 5000 Series

Also, when I try to start compiz manually using terminal I get following output:

          How to change which sound is reproduced for terminal bell?

          Image
          3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question ...
