ubuntuSince a lot of people seem to be struggling with this issue (getting good performance out of Intel Mobile Graphics chips on Ubunty Jaunty), I’ll give a quick heads-up on my findings again. I’m on an 945GM chip myself, so although this issue probably effects the whole range of chips using the xorg-intel driver, keep in mind that results may vary.

Last time I explained how I installed the xserver-xorg-video-intel driver from the X.org SWAT Launchpad PPA. This resulted in a performance increase and a fix for the swap-hogging problem. Behold, I was wrong about that last bit. Mock me behind the cut. Continue reading »

ubuntuA couple of weeks ago, I reported about a fix for Intel driver performance regression in Ubuntu 9.04 (Jaunty Jackalope). The fix solved the overal responsiveness of the interface (especially for composite-enabled desktops), but introduced a new problem which wasn’t visible at first: a memory leak slowly filling up swap space.

Over the course of 2 or 3 hours, my UXA-enabled driver would start to fill swap space with unrecoverable junk blocks. The only solution was to restart X before it grinded to a halt. This was not optimal, but I preferred restarting X over the clunky EXA method.

I’ve experimented with a new solution – read more behind the cut. Continue reading »

ubuntuAfter upgrading from Intrepid (8.10) to Jaunty (9.04) I noticed a noticeable performance hit, in 2d and 3d applications on my Ubuntu system, running a (rather crappy) Intel 945GM mobile graphics chip. After poking around on the Ubuntu forums I found this thread. The problem seems to be the switch between EXA and UXA in the new intel driver.

More tech talk and a solution behind the cut.
