Subject: ldm doesn't store default session

Date: Wed, 21 Jan 2009 12:19:58 +0100

Package: ldm
Version: 2:2.0.6-4
Severity: important


ldm doesn't remember between reboot the default session that I have 
chosen. When I reboot, I login, correct password and all, black screen 
and it comes back to the ldm prompt.

Selecting the session works, but I have to do it everytime I use ldm.

Where is this info about default session taken ? (with gdm it remembers
fine...)

Thanks.

this was fixed upstream in 2.0.21, and fixed in the debian experimental upload
2:2.0.21-1.

unfortunately, it would likely be difficult to backport those changes to the
version in lenny, especially this late in the freeze.

i'm not sure i understand you here, you mean that you cannot login after
rebooting the thin client? or it merely doesn't default to the previously
selected session?

it uses the defaults for /etc/alternatives/x-session-manager, which is a
systemwide default.

to configure per-user, you'd need to create a ~/.xsession
for each user that sets the session.

I am running ltsp in mixed environnement (not lenny) so I was able to add 
the experimental branch and 

   apt-get -uVf install ldm=2:2.0.28-1

But, things are worse. (Tried out a bunch of options) after typing my password
and entering, it shuts down X. Here is what I have in /var/log/ldm

Both. It doesn't remember the previously selected session, and loops back to 
ldm when correct password is entered.

$ update-alternatives --config x-session-manager

There are 4 alternatives which provide `x-session-manager'.

  Selection    Alternative
-----------------------------------------------
          1    /usr/bin/startkde
*+        2    /usr/bin/startlxde
          3    /usr/bin/openbox-session
          4    /usr/bin/gnome-session

I have an ~/.xsession with ion3 in it. I just realized it 
didn't have the +x in it's attributes, I've added and with test
on next reboot.

Nope, not better.

that sounds like a separate issue that maybe warrants it's own bug report. i've
definitely experienced similar problems, but not recently. please try it with
ltsp-client and ltsp-client-core from experimental as well. if you still have
problems with it, please report a separate bug.

looks like your default is set to startlxde...

well, all ldm does is call the server's /etc/X11/Xsession with "default" as an
argument. i think /etc/X11/Xsession first checks for ~/.xsession, failing that,
tries x-session-manager, failing that, tries x-window-manager, and failing
that, i think it tries an x-terminal-emulator. but if you've gotten that far,
you're already well past what ldm does...

the version of ldm in experimental uses the user's ~/.dmrc to determine which
session to try, which should be the same as what GDM uses.

if you select the "Default" session from GDM, i think it should use
~/.xsession if present.

live well,
  vagrant

p.s. please reply only to the bug report, and not to me directly. thanks!

The .xession, .dmrc are all in place, I still don't understand where it
is bugging, or even where I can find some debugging information. Nowhere
in the logs (client or server) do I find any usefull information. 

I even tried to add "set -x" to the scripts in /usr/lib/ldm/scripts 
but nothing came out of that. 

Any clues on how to proceed ? (I'm back on Version: 2:2.0.6-4 because
the upgrade of ltsp-client-core made things worse (no X - probably needs
to upgrade all packages...)

Version: 2:2.0.38-1

the version of ldm in unstable does preserve the selected session
between logins. if there are other outstanding issues, please report
them in separate bug reports.
