[Lubuntu-qa] Video Problems - Saucy

Fri Jul 12 13:39:44 UTC 2013

Yesterday I tested on my Core2Duo, a video on youtube on full screen, and
as I told you guys before, my cooler use to accelerate a bit. I usually
don't hear it's noise, and when I play something with flash CPU use
increses...

Well, on my latest test, my CPU usage came to 107%, as my processor is dual
core, that means 100% of a thread and 7% of the second one... And all that
only on the *plugin-containe* process...

You might want to check how much CPU% that process require on your machine
Ali, an *sudo top* might be better for this task!

PS: 68 C - 70 C is still acceptable. Most BIOS have auto-shutdown at about
85 to 92 degrees celsius...
