i'm using this on jaunty https://bugs.launchpad.net/~xorg-edgers/+archive/ppa and i shouldn't have kms enabled (didn't touch anything)

problem:
adobe flash performances are just awful, they decreased dramatically since i upgraded to this fresh git stuff, i.e. youtube is almost^W unusable (3ghz p4 cpu), everything else seems fine (didn't try any games or other stuff), with ubuntu jaunty's stock drivers everything (about flash) was better, even if it still sucked a bit though..

i didn't find a way to contact devs/packagers so i report my bug here :)


cheers

(sorry for bugmenot but i couldn't remember my account and i was in a hurry)

Adobe's flash does not use hw acceleration on the open source drivers.

That's total crap. I can watch 1080p videos on mplayer with the X11 non-accelerated renderer. Flash on Linux is so much crap, it even lags with 480p videos. You don't need any kind of acceleration for this. But Flash is crap and can't even do that right.

Crap, crap, crap. Oh, did I mention how crap Flash on Linux is?

[bugmenot]

Adobe's flash does not use hw acceleration on the open source drivers.

still the facts are that with stock jaunty drivers it consumed lots of cpu time but at least worked, now it's unusable, too much slow and choppy..

i did include a lot of random informations because i don't develop and i don't know how and if this could be useful..

[agd5f]

did you also change the version of flash you are using?

[bugmenot]

i'd say, no..

i have 10.0.32.18

Can you post the output of:
$ dmesg | grep drm
I suspect you have a KMS kernel without KMS support on mesa/ati.

[nanonyme]

Wait a minute.... Jaunty? 8.10? You didn't happen to be running the proprietary driver at that time? Since open drivers don't support GLSL (yet) which Adobe Flash uses for acceleration whereas proprietary drivers do.

edit: i'd add that in my lappy i have an intel 1.6ghz and intel gma(something), and flash (yes, adobe) works smoothly..

no proprietary drivers, i was running the 9.04-ati-stock-open-driver like, two days ago..

Never mind, must've read something wrong, got the wrong year. ;)

Looks like you have kernel oops there. Also profiling with sysprofile where the CPU time is going would give idea what might be wrong. (You will need to install debug symbols for mesa,xserver,firefox and ddx to get nice back trace)

i know all the cfs-bfs interactivity etc. story but i had this kernel also before using the xorg-git ppa, and flash didn't sucked _that_ much..


edit: from all the answers seems like you get flawless flash experience on your ati cards.. i guess i'm the only one that's having problems

[nanonyme]

Well, depends what you call flawless... I get working Flash with Flash taking 100% of a single core in my CPU. The system is still usable since it's a multicore one but it's still not remotely close to acceptable.
