I'll post here too my issue.
It's a foolish thing, but I don't know how to handle it since I don't know how to work in text mode... Huh
So, please don't laugh!...
Upgraded to KDE 4.10, typed in terminal init 6 to reboot.
After reboot it went in text mode
What should I type there??? Huh
The same thing in my 32 bit install after upgrading to (testing) kernel 3.4.
I tried root->password
Is shows a large list ended with
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
I need a hand, please...
