Hi, I've just run a software update on FC6. When I reboot and log in then the gnome window manager has been replaced by TWM. This was something of a shock although I have enough knowledge to realise what had happened. (I can't see why it happened though, other than saying there's a bug in the update). It has undermined my confidence in Fedora as a stable release somewhat. Looking at Linux answers then I found a suggestion to run: yum install gnome-session. This worked in bringing up gnome, which I was previously using. Unfortunately, the desktop is not quite as it was. I have a panel appearing which says: 'The panel encountered a problem loading OAFIID: Gnome_mixerApp Do you want to delete the applet from your config'. A similar error occurs for the Gnome_Panel_TrashApplet. Any suggestions how I can restore the desktop to what it was? Andrew, Oxford.
