Good old times. It's this time of the year again: the touchscreen is
broken yet another time.

The culprit is xserver-xorg-input-evdev: with 1:2.3.2-5 (unstable)
the clicks go somewhere, downgrading to 1:2.3.2-4 (testing) helps.

The difference I've found so far is:

1) in testing:

$ cat /lib/udev/rules.d/65-xorg-evdev.rules
ACTION!="add|change", GOTO="xorg_evdev_end"

# By default, we use the -evdev driver for every mouse, keyboard, touchscreen
# or touchpad; later rules can then change the driver for specific input
# devices.
KERNEL!="event*", GOTO="xorg_evdev_end"
ENV{ID_INPUT}=="", GOTO="xorg_evdev_end"
ENV{ID_INPUT_MOUSE}=="?*", ENV{x11_driver}="evdev"
ENV{ID_INPUT_KEY}=="?*", ENV{x11_driver}="evdev"
ENV{ID_INPUT_TOUCHSCREEN}=="?*", ENV{x11_driver}="evdev"
ENV{ID_INPUT_TOUCHPAD}=="?*", ENV{x11_driver}="evdev"

LABEL="xorg_evdev_end"

2) in unstable this file is removed, and there's a new one:

$ cat /lib/udev/rules.d/05-evdev.conf
# Catchall classes for input devices
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection


Now, does anyone know how to get this to work with tslib?
Or maybe it's not these files but some other changes in
xserver-xorg-input-evdev ...
