I have a thinkpad T520, and my touchpad stopped working after upgrade. I tracked /etc/acpi/events/lenovo-touchpad to a problem with the getXuser function in /usr/share/acpi-support/power-funcs.
I changed this line: user=$(who | awk "/:$displaynum)/ { print \$1; exit }") to this (escaping the parenthesis): user=$(who | awk "/:$displaynum\)/ { print \$1; exit }") and I was able to enable my touchpad. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/804109 Title: can't enable touchpad in Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/null/+bug/804109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
