Thanks Yoyo! I assume this will be part of final release? I don't want to mess up possible bug finding on this alpha release.
I'm also finding bugs in other places, and maybe this would solve them.
Such as System Settings>Startup and Shutdown>Service manager where if I try unticking/stopping one of the running services I get segmentation fault/crash (e.g. untick Bluedevil 'stop') or message 'unable to stop Bluedevil.
P.S. edited, just did the command and I will have to wait on this as it says there is a needed 531.58MB of packages to install. I'm sure some of them will fix some of my problems but I've already downloaded a bit too much this past month - my isp will have a fit.
