hotkey-setup: statusexplanation |
|
This only seems to show up on the X60*. Eg. on a R52 that has been up for a day, it's only used 20 seconds:
$ uptime ; ps aux | awk '/[t]hinkpad-keys/{print$11,$10}'
15:27:11 up 1 day, 6:20, 4 users, load average: 0.03, 0.07, 0.08
/usr/sbin/thinkpad-keys 0:20
sabdfl reported this to me and his X60 is SMP (Core Duo).
It may also, to a lesser extent, be visible on an R40e, jriddell has mentioned.
Chris: can you:
apt-get install tpb
(this will conflict with 'hotkey-setup' so you'll temporaily have to remove the 'ubuntu-desktop' meta package).
Can you check if the CPU usage on that is any different. (It should be 25% of the amount since 'tpb' polls at 5Hz by default and 'thinkpad-keys', currently at 20Hz.
I've thought of so ways to get the current 80 /dev/nvram queries per second down to ~11 and not loose much of the responsiveness/latency. |

I don't see anything showing this was actually tested on 2.6.22. Can someone confirm this is the correct target? |
