9:20 a.m.
This started after an update Friday. Get the login screen, system
accepts password, progress bar shows for about 1/3 of the way, then
get the dialog box about ksmserver crashing. I've done both "report
crash" and "create backtrace" both of which cycle me back to the login
screen.
I pull packages from here:
deb http://mirror.xcer.cz/trinity-sb trusty deps-r14 main-r14
Stuff I don't understand from the logs:

Shouldn't go changing things mid-troubleshoot, I know, but if I do a
"dpkg-reconfigure lightdm" and select tdm-trinity, I can't even get to
the login screen. Something is broken in TDE, but what? ksmserver?

I understand correctly that the creation of backtrace is not successful? You
can switch to the text console and use gdb from the command line?

Password accepted
1/3 progress bar, then "bomb" dialog
Click backtrace
Enter password
Text shows on window in dialog but before I can do anything (like read
it), the screen goes back then it cycles back to the login
So, if we assume it make a backtrace where would I find it? If its
not there, I'm happy to send output of both gdb and lsblk if you will
kindly send me a command line example.
THANK YOU!

A new fglrx dropped yesterday (ATI video card) and I was hoping that

If I wanted to remove TDE and re-install, what would be the best way
of doing that? I don't see a new LTS release of Ubuntu, else I'd just
go for that. I like the LTS releases because I'm not interested in
losing a day or 5 of productivity with an upgrade. Fortunately, this
initially happened late on Friday and I was not at work on Monday, so
I've only actually been out of service for 1 day, but I see no hope of
recovery today. At some point, I'd rather just re-install ... but ...

Hi Peter, I do not think it is that easy to catch this with gdb.
You are starting a new session, so ksmserver is started. It crashes and so tdm brings you
out and start anew.
I think you need to create a small monitoring script that monitors for ksmserver
instances, then if so grab the pid
and attach gdb to it. You need to run this script from CLI before logging into TDE.
Hopefully the script will be fast
enough to interrupt ksmserver before it crashes, then you can step through it, although it
may be a long process
before you get to the point where it crashes.
IMO, the update of last friday broke something in your installation or in your current
configuration.
1) have you tried creating a new user and logging into TDE as that user? Same crash?
2) if you run aptitude, do you see any broken dependency or errors?
3) did you update from one ubuntu version to another one or just updated
"within" the same version?
Cheers
Michele

New user doesn't work, either, but behavior is slightly different - no
progress bar, no bomb dialog, just accept password, black screen, then
back to user.
I always use apt-get update/apt-get dist-upgrade and accept whatever
is there. I have Slavek's repos for TDE.
This started as a Kubuntu install (new system, thought I'd give KDE4
another chance - silly me) but I ran screaming back to TDE.
For me, starting over with a new install (of something I know would
run TDE) is less painful than writing a gdb script! Fortunately, I've
got a Macbook, so I can still work, but I really need to get back to
where I was earlier Friday.
I checked - there is no "undo" button. :-D
