I'm using xorg 7.2(ubuntu gutsy), and because with the bundled driver my notebook's vga-output does not work, I use to build the intel driver from git.
From commit 34c82ad7ce on, my X does not start any more:
/usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/drivers/i810_drv.so: undefined symbol: i830_fixup_devices
i830_fixup_devices() is new function in i830_quirks.c, which trys to workaround any known device quirks. Did you have a clean build after git pulling?
btw, this 2d video bug should not go dri-devel list.
I think I cleaned the build a few times.
However, with some of the new versions, the problem does not happen any more. Thank you. :)
