I've recently installed Ubuntu 12.04 and I love it. However I have one problem- I am unable to shutdown or reboot properly.
When I shutdown my laptop (Acer Aspire 5560) it hangs on the 5 dots and stays there.
When I reboot my laptop it does shutdown but when it boots back up it stay's on the Purple screen (no logo what so ever)
Thing's I've I'd to stop this:
sudo service network-manager stopbefore shutdown - nothing
Adding some lines the the GRUB file - nothing
- installed other Ubuntu versions - nothing
sudo shutdown -h now- nothing
and some more.
At the moment I see a black screen in front of me with the text
Asking all remaining processes to terminate [OK]
And the 5 dots with only the last one orange.
On other tries I got this thing:
modem-manager:could not get the system bus......
I first had Ubuntu dual boot Windows. And then it worked fine. However after a fresh install of Ubuntu alone I got this.
