Does the screen light up at all when you power up? Or is it permanently
dead.

If it's always black, you probably have a dead screen.
If it lights up and lets you work for a bit, and then goes black,
it might be the backlight or the inverter.

I managed to fix mine...for the moment.

Trusting that the absent disk-light meant the update was paused for a
dialog, I held down the power button and forced a reboot. It came back
(so perhaps the black-out *wasn't* connected with the inverter?) with a
full-screen console and about 10 short messages that went past too fast
to read, then cleared and showed a login prompt.

I logged in and used sudo dpkg --configure -a to restart the upgrade.
This ran, but with some messages about missing configs, unresolved
dependencies etc -- I have seen these before in a normal upgrade to
15.10, so I think they are bugs rather than a breakage on my system.

Finally it finished and I rebooted normally, and it's running X again,
but if I use apt-get, there is a very long list of packages which it
*claims* are no longer needed, but at this stage I have no way to tell
if this is true or if it's a result of a few things having been messed
about in the process. In a normal version upgrade I'd expect maybe 10-20
packages no longer needed, but this list has maybe 50+. I'll leave it
until I do a regular upgrade (usually weekly) and see what happens.

Perhaps the reason for this is, that the init process switched from
upstart to systemd, this changed a lot.

[xubuntu-users] Screen blank during version upgrade

2016-02-07 Thread Peter Flynn 
I kicked off an upgrade on my laptop from 14.04 to 15.50 today and it
was all going well (half-way through the installation part) until my
screen went black (I had disabled the screensaver before I started).

The system is still running: I can log into it with ssh, and all the
expected upgrade processes are still there. In the moments after the
screen blacked out, the disk light was still flickering, so it was still
running. Now the light has gone out, almost certainly for one of those
prompts that version upgrade pop up, asking if I want to keep one of the
config files like ssh.conf or smb.conf -- and of course I can't click OK
because I can't see where the mouse is. Pressing Space also doesn't
work, presumably because the focus isn't on the dialog.

Is there a way to determine the process's exact status from a logged in
ssh job? I have appended the output of ps axu in case it helps. I can
just leave it running until I find out...

(I suspect the screen inverter, which has giving trouble, but I had that
replaced last week and it's been fine so far).
