[lubuntu-devel] "TTY" goes to black screen, then doesn't come out of it?

[Fritz Hudnut]

Folks:

Running Lu 20.04 install to cold metal . . . overall system seems fine, had
an issue with the "cups" crash, that seems to have been handled.

But, I've discovered that ubuntu doesn't seem to be providing a TTY log in
any more?  I ran a google on it, but nothing looked current, thought I saw
something on Lu users about it awhile back . . . I've got a few distros
installed, wanted to get into a TTY in U-Mate, but there I think screen
goes black but no log in cursor appears, seems like it's not "F1" anymore,
but "F3"?? possibly in U-MATE I was able to get back out of the blackness
with "F6" or F7???  But in any case it appears that in
ubuntu/U-MATE/Lubuntu installs and also Manjaro, that pressing the usual
keys gets to blackness, and in some cases not back out??? have to shut down
and cold boot.

Possibly this is some kind of "security" thing, but it is "traditional" in
linux to be able to get to single user shell, and out via key stroke.
Seems like if the devs want "no TTY log in" then it shouldn't respond to
the key strokes to go to black at all . . . and then not seemingly being
able to get back out once the screen has gone black.

Looked like some of the google threads going back to 12.04 & 14.04 were
also discussing this problem, that was then resolved in updates . . . an
idle question is why is this recurring?  Some times, like in pure Debian
they want updates/upgrades run in the TTY to prevent damage to the
filesystem or GUI stuff . . . that happened in my recent upgrade to U-MATE
20.04 with no TTY access, upgrade on GUI terminal couldn't seemingly
resolve issues with nvidia drivers and . . . then reboot took me to a shell
. . . i.e., no GUI was available.  Wound up having to run a fresh install
from usb flash drive to get it done, rather than running it via TTY, etc.

Playing with Lu this morning, keystrokes took me to black, no log in
cursor, etc.
