[Solved]Black Screen when I switch to tty1-6

i_love_r34 · 2016-03-20 04:26:32

Hi again!

My problem is when I switch to tty (crtl+alt+f1-f6) I get a black screen with blinking cursor instead of login screen, but I not have problem when I switch again to X.
I recently update the kernel and my graphic driver but I have the problem since I installed Arch.
I check the state of getty in systemctl but says all is fine:

    getty@tty3.service - Getty on tty3
   Loaded: loaded (/usr/lib/systemd/system/getty@.service; enabled; vendor preset: enabled)
   Active: active (running) since Sat 2016-03-19 20:20:05 PDT; 44min ago
     Docs: man:agetty(8)
           man:systemd-getty-generator(8)
           http://0pointer.de/blog/projects/serial-console.html
 Main PID: 1540 (agetty)
   CGroup: /system.slice/system-getty.slice/getty@tty3.service
           └─1540 /sbin/agetty --noclear tty3 linux

Mar 19 20:20:05 illuminati.eye systemd[1]: Started Getty on tty3.

And says the same in all status reports.

Dmesg and journalctl not have any error information about getty.

Any solution?

Thanks!

Details of your system may help to discover a solution.

 lspci -vnn | grep VGA

Brand and model of your computer.

The command give me this:
00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake Integrated Graphics [8086:191b] (rev 06) (prog-if 00 [VGA controller])

Also:

ps -au | grep [a]getty

By the informations you provided I found this for your MSI 14" GS40 Phantom
Try to disable nvidia

Currently I have the disabled the nvidia card of my computer by nouveau and nv in blacklist. I only use the Intel graphic card.

Additional Information:
When I switch to tty 1-6 the sound stops but when I switch to X the sound return to normality; in some cases, when I switch to tty and return to X, the applications show graphics errors (Like firefox shows error colors of the page or the applications shows bad colors of the interface)

Does any of those provide any useful info?

# journalctl -b _COMM=agetty

# journalctl -b _PID=pid

(replace pid with the actual PID of one of the agetty instances — the second column in the ps output).

One more think, try to stop the login manager and start the machine into non graphical state. From there issue startx and try what will happen when switching TTY.

Journalctl says:

[monesvol@illuminati ~]$ journalctl -b _COMM=agetty
-- No entries --

and:

[monesvol@illuminati ~]$ ps aux | grep agetty

Amazing, the ttys start with normality and serveral graphics errors fixed.
