Bug#616644: xdm: strange behaviour after logging out: not reading kbd or mouse
Package: xdm
Version: 1:1.1.10-3
Severity: important
Using xdm as session manager, after logging out from windowmanager (e16) session user has again xdm login screen. Strangely any input typed on kbd only gets echoed onscreen after moving the mouse. This "echo delay" includes the enter key as well as the VT switch keys (C+A+F[1-6]{1}).
Also a password containing some unusual chars (such as #@" and the like) is not recognised correctly then, so cannot login.
Alternatively (about every other time) the kbd input is echoed immediately (as normal) and recognised well, but the mouse is as dead as a doornail, and is not resurrected on entering windowmanager session. Strangely though a mouse tap seems to be noticed -- and reacted to -- only after having typed a key on the kbd. Pointer movement is nil, however.
This strange behaviour can be "re-set" to normal by switching to a VT and then back to VT7.
Note: This only happens after coming back to login screen after logging out from windowmanager session. On first login there's no problem at all (apart from the spaces echoed by the password field, s. bug #575486).
Not sure if this comes from xdm proper or some associated xlib.
Just noticed: same behaviour is also shown by xdm 1:1.1.8-5.
As noted before, my kernel is a custom kernel out of debian linux-source-2.6.30 which I have been using since its compilation without any of these X-related problems. Findings with std debian 2.6.32-5-686 #1 SMP Wed Jan 12 04:01:41 UTC 2011 i686 GNU/Linux are exactly the same.
Hardware: dell inspiron 1300 (laptop) with synaptics touchpad.
Brgds, e.
