New information regarding OpenGL application hangs and core dumps. Procedure - boot with kernel.i915 - do not load i915kms at loader - startx as normal user OR xdm via /etc/ttys, no difference Tested applications thus far: chrome, openarena, compton. When I use SNA acceleration, I can get OpenGL applications to work without core dumping. Sometimes fullscreen applications cause black areas to emerge over regions of other windows, which go away after resizing windows or doing something that triggers a redraw (damage event, probably). However, when I use UXA acceleration instead of SNA acceleration (by removing my intel specific configuration OR setting UXA directly in conf), openarena and compton both crash with core dump. Also, they blank the screen, and to get display back I have to vt switch back and forth. In short, the default UXA acceleration is broken for me in kernel.i915. I must use SNA acceleration, which works most of the time, except when it glitches so that damaged regions do not get redrawn. My config for SNA: # cat <<EOF >/usr/local/etc/X11/xorg.conf.d/10-intel.conf > Section "Device" > Identifier "Intel IGP" > Driver "intel" > Option "AccelMethod" "SNA" > Option "TearFree" "true" > EndSection I will produce a Test Scenario for this later, but for now I will just report my findings.
