Bug#626549: xserver-xorg-input-evdev: middle mouse button emulation doesn't anymore by default
severity 626549 important
I had this problem to. Bought a new laptop last sunday, installed
squeeze. Did a full upgrade to testing earlier this week, and middle
button emulation stopped.
I suggest adding a debconf prompt during upgrade, and creating a config
file snippet in /etc/X11/xorg.conf.d, with the appropriate option
enabled. I might even go so far as to suggest that new installs have
this prompt too.
If (upgrading & $old_version < $version_with_changed_default) ||
(new_install); then .. fi
Having this break during an upgrade is very bad, imho.
a bug which has a major effect on the usability of a package,
without rendering it completely unusable to everyone.
