When in 12.04, if I run Ubuntu-Tweak -> Janitor tab, check all boxes click Clean, after re-start ... my Ubuntu will in
tty1 mode. So I run what is instructed in https://wiki.ubuntu.com/Kernel/LTSEnablementStack and my Pangolin back normally.
But after upgrade to 14.04, yesterday I re-install Ubuntu-Tweak (in order to give it a try) and run it as before. but after restart ... I found the problem remains!
But now I really don't know what to do? Because when using utopic, it said
"server not found". By using trusty, it said all is
"the newest version"
I also run:
sudo apt-get install ubuntu-desktop but nothings happen.
And I tried
sudo service lightdm restart but the output is:
stop: unknown instance: stop: job failed to start
Ctrl+Alt+F7 but the output is just a sparkling
_ (underscore mark)
How to make my Ubuntu back in normal GUI?
