I think gmail is the problem. After starting firefox, before going to
gmail, the powertop output is not weird.
Top causes for wakeups:
31.4% (131.4) <interrupt> : i8042
14.5% ( 60.5) <interrupt> : nvidia
13.3% ( 55.6) mlterm : schedule_timeout (process_timeout)
8.1% ( 34.0) Xorg : schedule_timeout (process_timeout)
7.7% ( 32.0) S06cpuspeed : queue_delayed_work_on (delayed_work_timer_fn
7.1% ( 29.5) <interrupt> : extra timer interrupt
After going to may gmail account, where I read this email list, look what I see:
28.2% (183.0) firefox-bin : schedule_timeout (process_timeout)
15.6% (101.7) <interrupt> : i8042
9.3% ( 60.7) <interrupt> : nvidia
9.2% ( 59.7) mlterm : schedule_timeout (process_timeout)
7.6% ( 49.7) S06cpuspeed : queue_delayed_work_on (delayed_work_timer_fn
6.7% ( 43.7) Xorg : schedule_timeout (process_timeout)
6.2% ( 40.0) <interrupt> : ipw3945
5.2% ( 33.7) <interrupt> : extra timer interrupt
4.5% ( 29.0) Xorg : do_setitimer (it_real_fn)
The mlterm checks, well, I can't explain them. I use mlterm because
it is the only unicode-ready terminal program that I can find that
allows me to set scalable images on the background from the command
line. Since gnome-terminal removed the pixmap option from the cli, I
don't use it. If anybody has a suggestion there, I'd switch. Eterm
does not support unicode.
