On occasion, pressing Ctrl+Alt+F1 does not reveal the tty input. Instead there is a single non-flashing horizontal cursor on a black screen. This isn't an issue, until debugging is required (for example, when I get strange errors about the lock screen failing, a separate issue). I have never seen this problem before on my other Tumbleweed installation, so I am wondering why it would show itself here on my Asus UX31LA, and how should I investigate it?

Does it remain black indefinitely, or does a login prompt eventually appear? Are ttys 2-5 also black screens except for cursor when this happens on tty1?

I don't have patience. When I want a vtty, which is very very very often, I want it with zero delay: #!/bin/sh cd /etc/systemd/system/getty.target.wants cp -a ../../../../usr/lib/systemd/system/getty@.service ../../../../usr/lib/systemd/system/getty@tty1.service sed -i 's/TTYVTDisallocate=yes/TTYVTDisallocate=no/' ../../../../usr/lib/systemd/system/getty@tty1.service ln -sf ../../../../usr/lib/systemd/system/getty@tty1.service ./getty@tty1.service systemctl start getty@tty1.service ln -sf ../../../../usr/lib/systemd/system/getty@.service ./getty@tty2.service systemctl start getty@tty2.service ln -sf ../../../../usr/lib/systemd/system/getty@.service ./getty@tty3.service systemctl start getty@tty3.service ln -sf ../../../../usr/lib/systemd/system/getty@.service ./getty@tty4.service systemctl start getty@tty4.service ln -sf ../../../../usr/lib/systemd/system/getty@.service ./getty@tty5.service systemctl start getty@tty5.service ln -sf ../../../../usr/lib/systemd/system/getty@.service ./getty@tty6.service systemctl start getty@tty6.service -- "The wise are known for their understanding, and pleasant words are persuasive."

It stays black indefinitely. I have waited for half a day before restarting just to see if it reappears.

It's all of them, except for F7, which is the desktop.

Same here. On booting up, everything seems normal, then after some time, I check back and nothing appears. It only occurs on my Asus UX31LA. My desktop never shows this issue.

What does `systemctl status getty@tty1` say?

Is it i915? If so, this might be the bug 966179. More data points are appreciated, especially whether you're using GDM with Wayland or not. Takashi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Yes, it is running the i915 kernel module. I am using the stock Tumbleweed setup, so SDDM and X. I can provide any other information you think that would be helpful. Thanks for the link to the bug report. Hopefully the next kernel patch will resolve this issue.
