run xinit and switch console with Ctrl+fn+alt+F2, then switch back with alt+F1, you will see the message below. And seems the xinit is not running.

Ctrl-alt-F7 sometimes looks fine. But this issue also happens sometimes.
Comment 3 Chris Wilson 2015-03-06 08:00:39 UTC 
Could you please attach the full Xorg.0.log?

Comment 5 Chris Wilson 2015-03-06 08:52:19 UTC 
On this system, X is on VT 7. So the test sequence should be chvt 2; chvt 7:

"run xinit and switch console with Ctrl+fn+alt+F2, then switch back with alt+F7"
Comment 6 Ding Heng 2015-03-06 09:27:21 UTC 
I made a mistake that I didn't know the right way to back to X. Close.
