For me, with (sysvinit) BLFS-7.7 I had no issues, and sna is the default - that system was compiled against 3.19.0 but was running 4.0.3. It looks as if --enable-uxa was used when I configured it. On the new build, I've now rebuilt the intel driver with --enable-uxa but I had to add a conf file to force it to use uxa instead of sna, otherwise it still segfaulted. ken@jtm1 ~ $cat /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection I got that from Arch - normally I put conf files in /usr/share/xorg.conf.d with X in /usr, but I thought I would try /etc/X11/xorg.conf.d. No idea what changed - any pointers to Chris's post(s) ? At the moment, the intel driver is now working, but SNA (Sandybridge's New Acceleration) segfaults - and I had been using SNA for ages because this i3 _is_ a SandyBridge. ĸen -- Nanny Ogg usually went to bed early.
