Hello.

I just upgraded some libraries, restarted Debian stable (Jessie)'s
kdm.service, but it got stuck in black console with no X. "startx" fails
to launch it. :( How do I relaunch KDM without rebooting my old desktop
computer?

Thank you in advance. :)

startx >/tmp/X.log 2>&1
and you can then read the output of startx to see if there are any clues
as to what is going wrong. A black X tells nothing about why.

Note that you might want to try rebooting.

I meant without rebooting the computer. I know a reboot will fix it.

Why don't you want to fix it?

Anyway, make sure you log out of X ( that nothing X is running. Then try
the startx above and look into the logs to see what is problematic.
Note you want to make sure that you go into runlevel 3 (or whatever
Debian calls it without X)
Then use startx.

You're not rebooting the computer. Just execute

startx >/tmp/X.log 2>&1

and after it failed have a look into /tmp/X.log to get an idea what's
wrong.

I use a Unix based operating system, which means I get laid almost as often
as I have to reboot my computer.
