I use an Acer Aspire One with Xubuntu (12.04). Last night I installed a few updates, only the security ones because it was late. It finished OK with a message about needing to restart for the changes to be effective.
Today I have 3 issues:
The first is that network manager is misbehaving. The network icon is 2 little arrows.
Hovering over it gives the help text:
Clicking on it says:
NetworkManager is not running... and a right click shows a limited menu (3 lines) with only one option not greyed out:
If I check with service network-manager start, it says start:
Job is already running: network-manager. I tried to stop then, restart. The networking icon hasn't changed, but the messages are different: Hovering over it is still the same (
networking disabled) but with left click it says
No network devices are available (in grey) and I can click on
VPN connections. While on right click it gives the same menu as previously, but now the greyed out
Enable networking has a tick in front of it.
I searched online, and the closest I found was this. Although I am not running Mate.
The second problem is that when I click on the Shutdown icon I get an error window:
Unable to perform shutdown Shutdown command failed
And I can only click on Quit or hit enter, which brings me to a login screen. Attempts to shutdown from there fail too. I can however shutdown by typing
sudo shutdown -P 0 in a Terminal.
Finally, the USB ports do not work, in as much as I cannot mount anything inserted. The memory slot does not work either. As I only noticed this last issue after posting my original question I will go and search online some more to see if I can revert to the pre-upgrade situation without going online nor using a USB port.
