I've hit this problem via installing PCBSD 9.1 RC2 albeit amd64 not
i386. I couldn't even get VESA mode to work. Similar platform: Dell 15R
SE 7520 with i7-3612QM including integrated Intel HD 4000 (GT2) and
XAA acceleration was awful in that it produced approximately 5 second
lag on some events like:
bring new window to front
repainting a part of window previously obscured by another window
expanding drop-down menus (e.g. <SELECT> tags)
With some effort I do have a good, working desktop environment now.
I've updated to:
Mesa 8.0.4 (libGL, dri, libGLU, libGLw)
This allowed me to use SNA acceleration which works lovely.
I did need to modify the above for FreeBSD though. I can supply patches
if anyone is interested?
I'm writing this here in case it helps anyone and also to alert the port
maintainers in case they want to bump the versions.
It does seem like the versions I'm using are way ahead of what's even
being tested for Xorg 7.7 and there's the sticky issues about jumping up
the Mesa 8.x.x and WITH_NEW_XORG flag. Maybe I didn't need to upgrade so
far. I could try downgrading if that's of any use to anyone?
Let me know if I can be of any use!
