[gentoo-user] xdm doesn't restart on killed X

[Doki Pen]

I've recently switched from gdm to xdm in an effort to reduce my distro
size. The only problem I've run into is that when I kill my X session,
xdm doesn't restart automatically. I have to switch to a vtty and type
exec sudo /etc/init.d/xdm restart. I've read the man pages and googled
but can't come up with a solution. Does anyone know if there is a way
to fix this issue?

When X exists, is xdm still running or has it died too?

You can tell when restarting xdm if it gives errors about xdm not running when
the "stop" phase of "restart"" is run

xdm is not running after I kill my xsession. It is running after I log
in. I tested using ps -Af | grep -i xdm.

[Alan McKinnon]

Ok, so I reckon the init script dies because xdm dies when X exists.

is there anything relevant in your messages log file, Xorg.0.log, ~/.xsession-
errors and similar logs?

[doki...@doki-pen.org]

From /var/log/Xorg.0.log.old:

Backtrace:
0: /usr/bin/X(xorg_backtrace+0x38) [0x812a180]

Fatal server error:
Caught signal 11. Server aborting

Nothing useful in .xession-errors

[Alan McKinnon]

That's a segfault so there's a serious bug. It's likely in X itself.

Did you recently upgrade X and at the same time rebuild all it's app and all
drivers - without exception?

[doki...@doki-pen.org]

This has happened since I have switched to xdm. I've run revdep-rebuild
and lafilefixer since my last X upgrade. Is there any other way to
check for broken libs?

[Alan McKinnon]

Checking for broken libs is not going to fix a segfault.....

Downgrade xdm methinks

So what should I do? upgrade X? upgrade xdm?
