This is a known bug and there is bug lodged here. https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/363478/ I have appended the details below to the bug report.
Since the UbuntuStudio is unstable on my notebook then I shall use the non-realtime kernel for the timebeing, and shall consider using the next release of UbuntuStudio. A shame because I am really impressed with the visual layout of Studio. Gnome looks very nice on it. Is there a easy way to have the same UbuntuStudio layout/theme on Ubuntu? Can I download the theme from somewhere? Best regards, s. <quote who="Simon L"> > Morning All, > > I have reinstalled completely from scratch.
