Description Arjan van de Ven 2006-09-03 04:18:54 EDT
Description of problem: GPM wakes up every 2 seconds to poll the console, even when in runlevel 5. This is causing spurious wakeups which cause less powersaving than possible. gpm does the polling since in X mode gpm has to be inactive, so it is waiting for X to go away / the user to switch to text mode. It polls for this every 2 seconds. I question the usefulness of gpm (in default install!) in runlevel 5, but if it has to stay, the attached patch slightly modifies gpm such that the wakeup will happen at exactly the second tick (where it will coincide with other similar wakups in other programs such as hal) and not cause a wakeup-from-powermanagement-sleep all on it's own.

Created attachment 135455 [details] patch to round the 2 second sleep up to a full wallclock second boundary
Comment 2 Arjan van de Ven 2006-10-09 11:06:10 EDT
ping? any ideas why gpm is even started in runlevel 5?
Comment 3 Petr Rockai 2006-10-09 15:24:10 EDT
Sorry, no, no idea, if it was for me, i'd just scrap it as it is :). I can apply the patch, although it is probably still somewhat suboptimal to have gpm running at all. If there are no objections i'll drop it from runlevel 5.
