I have F12 running as guest in Virtualbox. The F12 install had been working well for some time.
I am now having an issue with the following characteristics:
1. Upon bootup when I come to the gdm greeter list it does not have a user list, only the option for "Other"
2. If I do log on, and then attempt to reboot the system through the System->Shutdown menu, I often get only the options to Hibernate or Cancel. This seems to happen randomly and other times I get the normal options to Hibernate, Reboot, Shutdown, or Cancel.
3. Also, randomly, I am unable to mount a USB drive, receiving a lack of permissions error.
4. Also, randomly, if I issue the 'shutdown now' command as root, the system locks up and must be reset.
Issues 2-4 always happen (or don't happen) together. Either I have all of the problems 2-4 or it acts normally. Issue #1 always occurs.
I have found that if I disable networking, through Network Manager applet, and reboot, everything works fine (obviously with no networking) including getting the expected Greeter user list. If I have networking enabled, the networking itself seem to work fine, but I get issues 1-4 as above.
Any help would be appreciated. If any particular log/command output would be helpful, please indicate and I will submit it.
