Comment 12 for bug 388368

Yes, EXA support has been removed as of 2.7.99.x, and specifying that in
xorg.conf has no effect.

The main reason I included "(UXA bug)" is so it would show up on my
weekly UXA bug list report I send to Intel for bug escalation purposes.

The first thing I do after starting X is normally to start a pterm and maximise it; the first sign of trouble is that the scrollbar takes ages to be replaced by normal black terminal area on maximisation. After that, Xorg is using nearly 100% CPU, text scrolling is very slow, etc. Typing this report is excruciatingly painful because it can take up to a second for each character to appear, especially when the typeahead buffer gets at all full.

Bizarrely, this is visible in a screenshot (I'm not using compiz or anything fancy like that), which I'll attach to this bug.
