xdm and gpm conflict
Package: xbase and gpm
Version: 3.1.2 and 1.00
Revision: 2 and 1
Today, when I restarted my machine, I found that xdm won't behave
meaningfully with gpm running.
My initial problem (before reboot) was that control-R killed xdm
(instead of getting me another login prompt). Furthermore, when I
started xdm manually, it exited immediately. So, I rebooted to see if
that would clean things up...
When I rebooted, xdm generated a black screen alternating with some
noisey horizontal white lines in the middle half of the screen --
cycle time was on the order of one second. I didn't like this so I
hit a variety of keys to attempt to regain control (mostly stuff like
control-alt-f1, control-alt-f2, and control-r). After a half-dozen
cycles or so, it terminated with a general protection fault:

Poking around a bit, I remembered that I'd installed gpm. Looking at
the manual page for gpm (and xdm), I noticed mention of a potential
conflict on the gpm page -- something about how gpm would conflict
with X if a single-open mouse were being used. So, I de-installed
gpm. I think I tried xdm again at that point and had it not work --
so maybe there are some other pieces to this puzzle. Anyways, I
rebooted a second time and xdm came up ok.
Probably later on I'll try playing with xdm some more to see if I can
discover further aspects to this problem.
