tty2 - tty6 not working.

After switching to tty2 to tty6 by pressing 'ctrl + alt + F2 - F6', only one underline cursor appearing (no blinking) on the blank screen, the normal login prompter doesn't show up. It seems that the tty gets stuck. This situation usually occurs after the system has a long run and can be fixed by rebooting. I don't know if this is a kernel related problem, my ubuntu16.04 has the same problem as well, but Debian 8 with kernel 3.16 works fine.

Does anyone have a clue?

Re: tty2 - tty6 not working.

What is your hardware?

What does the systemd journal record when you have these problems?

You probably want to look at:

journalctl -u getty@tty2.service # or so

The journal seems fine:

Jan 16 00:08:07 tri-linux systemd[1]: Started Getty on tty3.

The journal of other ttys almost the same except the information of failed login.

My hardware is Thinkpad X201, the arch is fresh installed and updated.

Today the problem appears again, tty2 ~ tty6 all get stuck and has the same contents on the screen:

Arch Linux 4.4.39-1-lts (tty6)

linux login: ls (I was mis-typed before)
Password:

The most wired thing is that all the ttys display the same contents which has (tty6).

Re: tty2 - tty6 not working.

well, I can input my username and password blindly (the screen keeps unchanged, but the journal told me that I was successfully logged in). Maybe this is a video related problem.

Re: tty2 - tty6 not working.

Are you able to type in your user name and password and run commands blindly?

I have this issue, too (ThinkPad X230) - and whenever I'm stuck in there, I can log in and reboot the machine blindly.

Oooh, I have one of those — for the record, OpenBSD-current switches TTYs just fine on that hardware

Have you tried a different (non-LTS) kernel?

You could also try an early KMS start for the i915 driver:

Re: tty2 - tty6 not working.

Well, I gave a whole system upgrade (pacman -Syu) yesterday, and many packages got updated, including lts kernel (now is 4.4.42), xorg-server, gcc, etc. Until now, the problem hasn't appear yet, I don't know if it is fixed... The mainly related packages which may fix this problem are kernel and xorg-server, but I am not sure about it.

Yes, I can reboot my computer via blindly typing reboot command in one of the six ttys. The tty screen seems not be refreshed when this problem occurs.

Haven't try non-lts kernel yet, the recently update seems fixed this problem and I need some time to confirm it.
