[Bug 310857] Re: [i965] intel driver seems to get stuck in an EDID-fetching loop

[Colin Watson]

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.
