Comment 3 for bug 310857

While the EDID messages appear a few times in the log after startup, this isn't immediately followed by severe performance degradation (although, subjectively, this version of X seems rather "jerkier" than that in Ubuntu 8.10). It's only when X goes into a real death spiral that I see these messages appearing in rapid succession in the log.

Anecdotally, this only seems to happen after removing the laptop from my desk and going to use it elsewhere, which is accompanied by removing mains power and the Ethernet cable. I have a hard time seeing how either of those could be directly related to X, but, of the two, being on battery power seems the more likely!

I tried xf86-video-intel.git 5f347020a52b583e19d333361ea7bf2591255899 (much newer than that required a newer libdrm than is currently in jaunty), with no obvious difference. As long as I build it myself (I know the server ABI has changed), is it possible for me to roll back to the Intel driver from 8.10 without having to roll back the server and everything else too? This bug is having a serious negative effect on my ability to use my laptop, and I'd like to try to figure out when this was introduced.
