Title:
Video playback performance drops substantially after suspend/wake
cycle (Lenovo X201 i5 w/ Intel GMA HD)
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Binary package hint: xserver-xorg-video-intel
Note: I'm not 100% sure that this issue is with the driver, but it's
my best guess and I figured it would include the most relevant
diagnostic info.
I'm using Ubuntu 10.10 32-bit on a Lenovo X201 (i5, Intel GMA HD
graphics). When I first boot, video playback for Flash and HTML5
videos in Chrome and Firefox is smooth. But if I suspend then wake up,
it drops noticeably. A few examples:
- HTML5 videos play smoothly after a reboot. Once I suspend/wake, they're
choppy at best. Regular-sized videos seem to play fine regardless of size.
- Flash videos play smoothly (albeit with the usual Flash bugginess) after a
reboot. Once I suspend/wake, they're *really* choppy on Chrome, and bring
Firefox to its knees (it freezes for seconds at a time).
Playing videos in Movie Player doesn't seem to be affected by this,
but I'm not sure if this is just a result of it being so much more
efficient than the browsers that the performance drop isn't visible.
Likewise, I'm not sure if there's a qualitative difference between the
full-screen and regular-sized videos in Chrome and Firefox, or if the
added load of scaling the videos is making the performance hit
noticeable.
I've tried both 64-bit and 32-bit 10.10, and both seem to suffer from
exactly the same problem. I don't recall this being an issue in 10.04
--I only used it for a month or so before 10.10 was released, but I
think I would have noticed this regardless.
