Title:
12.04 black screen with blinking cursor
Problem still exists in 13.10 64-bit
lightdm version 1.8.4.0ubuntu1
Only restart of LightDM (sudo service lightdm restart) from a terminal
(with Alt-F1) resolves the problem, but it also kills the running
session.
Because this is such a long standing and basic bug (mind you: one only

I am also affected by this issue
Running 12.04 full updated.
Same scenario as above
Logged in as account 1 - autologin enabled
Switch to Account 2
- sometimes make it, sometimes get the black screen
Only resolution is CTRL+ALT+DEL (complete restart) or CTRL + ALT+F7 to
go back to Account 1.

only way to resolve is to reload the fglrx module and restart GDM3

I've had the same problem for months on 12.04. I was considering an
upgrade to address it. I'm disappointed to hear that this is still an
issue in 13.10, and agree with A.W. Thomas that importance should be
higher.

I'm still having this problem in 13.10.
Importance ought to be higher considering that a rather basic feature is broken
workarounds require restart/terminal fixes, no?

I have this problem only after installing a clean Ubuntu 12.04.2. The
new hardware stack (*-lts-quantal) is installed by default.
Here is a typical case to reproduce:
1) Only user A is logged in
2) Switch to user B via indicator (using HUD) - Success
3) Switch back to user A via indicator (using

Title:
12.04 black screen with blinking cursor when switching
We have the same problem here with 12.04. Usually my wife is affected
when she wakes the PC up (from Sleep) after I was using it, and attempts
to Start New Session, but ends up with a black screen and the cursor
blinking in the top left corner. The problem has persisted through
several updates. We
This bug also affects me and my family all the time. Usually happens
when my kids or wife try to switch users after I am logged in. When it
happens, I can always hit alt+f7 to get back to my logged in shell but
unless I actually log out, nobody else can use the computer. I am using
12.04.1 LTS
No problem. After it happened this last time, I booted using a boot cd
to copy the file, so the last entries you see will have happened right
before I had to manually shut it down. Here it is. Logins changed to
preserve anonymity.

Note that sometimes when I log in to an account that is already in use,
it attempts to log in and then fails, indicating that the account is no
longer logged in. However, you can then login as per normal, just that
everything you had open is no longer open. Annoying, but it doesn't
hang. This
Additionally, when this happens sometimes my computer is unresponsive.
None of the ctrl-alt-F* keys do anything, nor does ctrl-alt-del or for
that matter any other key combination I try. The cursor still flashes
though, so the computer itself did not freeze.

I also note that something similar used to happen in Hardy, though I
can't recall whether the cursor would flash or not. Note that this
doesn't happen every time either, usually only maybe after a few days to
a couple weeks. But like one of the other people people here have said,
the user will be

Pressing ctrl+alt+del when this happens reboots the system. Not sure why
someone would want to do that though, it is much easier to hit
ctrl+alt+f7 and will ensure nothing is corrupted or lost for the current
user.

How many users do you have logged in? It would help to have steps on
changes, logout actions ... like does it happen only after you logged
out from some accounts? Or does it happen with 2 accounts and changing
between those?
