Bug Description

Binary package hint: pbbuttonsd

Dapper gives the error message "/dev/pmu does not exist" when trying to start pbbuttonsd. It seems that it does not check if the system has a PMU chip or not.

I've attached a patch that tests for the CUDA chip and exits gracefully if it is found. Maybe the test should be reversed to search for a PMU chip, but I have no such system to test the patch on.

Test for CUDA chip and exit if found to avoid the "/dev/pmu does not exist" error.

Looking at the kernel, sources I think it is safer to test for /proc/pmu.

   * debian/pbbuttonsd.init: Immediately exit if /proc/pmu does not exist, i.
     e. if the system does not have a PMU chip. This avoids error messages on
     systems with CUDA. Closes: LP#47419
