Comment 544 for bug 550625

the patch provided in #492 doesn't work on my Dell n5110 laptop. I am using 64bit ubuntu 11.10.

$uname -a

The 'echo 1 | sudo tee /sys/module/psmouse/parameters/alps_dump_packets' command returns:
<code>
tee: /sys/module/psmouse/parameters/alps_dump_packets: No such file or directory

</code>

dmesg (see attachment) shows the following error:
<code>
psmouse.c: Failed to enable mouse on isa0060/serio1
</code>
