Subject: gdm: Suppresses X logging with "Too much output"

Package: gdm
Version: 2.6.0.4-1
Severity: grave
Justification: Discards error output rather than logging as requested

When an X session has been running for a while, I get the message
"...Too much output, ignoring rest..." and then all logging to my
~/.xsession-errors stops.

I googled for this message, and the only relevant hit I got
<http://cvs.gnome.org/viewcvs/gdm2/daemon/slave.c?rev=1.276> suggests
that GDM is responsible for this message.

<http://cvs.gnome.org/viewcvs/gdm2/daemon/gdm.h?rev=1.176> defines
MAX_XSESSION_ERROR_BYTES to be 80*2500 -- I guess that's supposed to
be 2500 lines at full width. (My current .xsession-errors which just
got this message is actually 4422 lines, for comparison, but about
half of those are empty, because many programs seem to include a
spurious newline with each message.)

This limitation seems a bit ill-conceived. I can imagine that it might
be useful to limit the output produced by a runaway process in rapid
succession, but it should still be possible to get log messages from a
process which runs for as long as the computer is up; eventually, if
there are no crashes or power failures, it will produce enough log
messages to exceed whatever limit you come up with.

Still, as a workaround, perhaps the Debian package could make the
limit really large.

In the meantime, feel free to tag this as "upstream" and forwarding it
to the Gnome folks.

Ultimately, the limit should probably be configurable at startup time,
with an option to disable it (perhaps by setting the limit to 0 in the
configuration), and documented.

Thanks in advance for your attention to this,
