[Bug 657976] Re: [Intel GMA 945/950] Unity Interface Is Extremely Slow (Ubuntu Netbook 10.10)

 

Hi everyone - I'm one of the devs that have spent extensive time chasing
this slowness issue. I assure you I can relate to your disappointment
over a sluggish system. It's buggering me a lot as well.

The problem is that on some systems Unity runs perfectly fast (for
instance on my Eee 1001, intel 945GME, Atom N270, which is definitely
*not* a high end netbook by today's standards - on the contrary :-)),
while on other systems (also with much higher specs) it runs very
slowly. This makes it pretty tricky to debug if you don't have the right
hardware as you can imagine.

So; any thoughts, tinkering, playing around, or hardcore profiling you
guys do are most appreciated! While I can see that there is a lot of
general slowness - it would be most valuable to hear if *anything* runs
fast? That could make it easier to narrow down the problem.

While you're at it, you might also want to try an run Unity with the
environment variable CLUTTER_VBLANK=none set. This has reportedly fixed
the issue for some. To test it out simply run 'CLUTTER_VBLANK=none
mutter --replace' from a terminal. If it works for you, you can make it
permanent by executing 'sudo echo "CLUTTER_VBLANK=none" >>
/etc/X11/Xsession.d/10unity-quirks'.

Thanks for all the input so far!
