[pkg-fso-maint] Bug#523911: xserver-xorg-input-tslib: please document that Device may not be specified with hal

[Timo Juhani Lindfors]

Package: xserver-xorg-input-tslib
Version: 0.0.5-8
Severity: wishlist

[ Cc added to pkg-fso-maint at lists.alioth.debian.org since their
install.sh configures tslib with Device option and thus does not work
with new Xorg that has hal as a dependency. ]

If I specify 
        Option      "Device" "/dev/input/event1"
and I run hal I get very odd behavior (pointer moves but I can click
only once). Please consider documenting this in tslib(4). Details
follow:

Steps to reproduce:
0) make sure hald is running
1) cat > /etc/X11/xorg.conf <<EOF

2) sudo Xorg
3) export DISPLAY=:0
4) icewm
5) xev
6) touch the screen briefly

Expected results:
6) xev sees ButtonPress, MotionNotify and ButtonRelease events

Actual results:
6) xev sees only ButtonPress and MotionNotify events:

EnterNotify event, serial 30, synthetic NO, window 0x400001,
    root 0x41, subw 0x0, time 5355011, (124,124), root:(128,148),

    state 0x100, is_hint 0, same_screen YES

MotionNotify event, serial 30, synthetic NO, window 0x400001,
    root 0x41, subw 0x0, time 5355055, (124,124), root:(128,148),
    state 0x100, is_hint 0, same_screen YES

MotionNotify event, serial 30, synthetic NO, window 0x400001,
    root 0x41, subw 0x0, time 5355111, (124,124), root:(128,148),
    state 0x100, is_hint 0, same_screen YES

More info:
1) If screen is touched again xev only sees MotionNotify events.
2) If I /etc/init.d/hal stop and restart X then xev works fine.
3) This bug is not related to version 0.0.5-8 specifically since it also
occurs with older versions.
4) I am using openmoko neo freerunner and Milko Krachounov on
#openmoko-debian managed to reproduce this bug with openmoko neo1973.

5) I don't hit the bug if I comment out the

        Option      "Device" "/dev/input/event1"

line completely.
