Bug#290916: gdm always stops working altogether after a few days

2005-05-23 Thread Ludovic Drolez 

Hi !

I confirm that sometimes we hit the same bug. It's really annoying since it 
happens randomly. Moreover since more and more people are using terminal servers 
like us, when gdm does not want to reply to XDMCP queries that's not one user 
which cannot work but dozen or even hundreds of users ! (Hopefully, in that case 
application servers are load balanced).


I also know that this bug was also present in woody.

Also, we got it without mounting something on the LTSP, or with a simple Xnest.

Cheers,

Bug#290916: gdm always stops working altogether after a few days (no response to xdmcp)

2005-02-05 Thread Steve Langasek 
severity 290916 grave
thanks

Thomas,

Please make sure that when you adjust bug severities, there's a clear
rationale visible in the bug log (rationales embedded in messages to control
require digging to get at from the webpage, and are not sent to the
maintainer).

 I use gdm and I have never seen this bug.  If it happens so rarely even
 to the submitter then I don't think that the package is unusable.

Do you use XDMCP?  I imagine that XDMCP is not the *most* common use case
these days, but I think it's still important enough that if XDMCP is really
this broken in GDM, it should be fixed (or at least prominently documented)
before release.

The submitter did not report this problem to be rare, he reported that
it's happened 8 times in a single month -- this is unbearably frequent in
many terminal server environments.  I would like to see comments from an
XDMCP user that this bug is not reproducible, or else a comment from Ryan
that he doesn't believe XDMCP should be RC, before this bug is downgraded
again.

Please keep in mind that the purpose of a BSP is to *improve the quality of
Debian*, not merely to hide bugs from view so that we can release.  It would
have been nice if you had made an effort to fix this bug instead of just
downgrading it.

Bug#290916: gdm always stops working altogether after a few days (no response to xdmcp)

2005-01-17 Thread Vaclav Smilauer 
Package: gdm
Version: 2.6.0.4-1
Severity: grave
Justification: renders package unusable


GDM manages a few dozens of thin clients. After a variable time (few days), it 
stops working - clients start X server without getting any 
login screen. Gdm must be restarted (or even -KILLed) (shooting down any X 
sessions already running), then everything works again. 
This happened about 8 times in the last month. Problem is not specific to a 
single client, after THE MOMENT XDMCP works nowhere. Limits 
set in gdm.conf (MaxSessions=1024,DisplaysPerHost=4) can be never exceeded. I 
read about DNS-related problemswith XDMCP, but that does not 
seem to be the problem here; the DNS server is rather reliable.

X server logs from thin clients show nothing interesting.

Relevant portion of gdm debug log (obviously 12:52:40 problem happened, 14:35 
killed and started again) is below.

Help is very needed and greatly appreciated, I will be glad to send any 
additional information.

Regards, Vaclav Smilauer
