I am unable to use the battery monitor in KDE-3.2 with included kernel-2.6.1. The problem is solved by recompiling and installing kernel-2.6.2.
With the old kernel, does anything happen if you run: chmod 644 /proc/acpi/event ?
Hello Bill, I've rebooted into the 2.6.1 kernel after having booted on the 2.6.2 and the problem seems to have corrected itself. But just FYI the permissions for /proc/acpi/event is 400 (root owner)
OK, if it works for you now...
