After some time using xorg-6.8.2, the mouse pointer will stick to the left side of the screen - https://bugs.freedesktop.org/show_bug.cgi?id=3113 - using the PaX kernel option CONFIG_PAX_KERNEXEC - there is already a comment from a gentoo hardened user. I compiled and ran (10 times) the OpenBSD fpsig.c regression test with and without the kernel option. With CONFIG_PAX_KERNEXEC not set I got no output but with the option enabled I got: no output on the first time I ran the regression test, but then... a.out: 5700.000000 5400.000000 a.out: 5700.000000 5333.000000 a.out: 5700.000000 5470.000000 a.out: 5700.000000 5370.000000 a.out: 5700.000000 5320.000000 a.out: 5700.000000 nan a.out: 5700.000000 1725.000000 a.out: 5700.000000 285.000000 a.out: 5700.000000 5370.000000 Steps to reproduce: 1) compile the hardened kernel with CONFIG_PAX_KERNEXEC=y 2) start some GTK2 programs 3) the time the mouse will stick to the left side varies, sometimes starting firefox is enough Fix: Apply this patch - https://bugs.freedesktop.org/show_bug.cgi?id=3113#c9. I got xorg-6.8.2-r6 running with this patch and haven't had any issues in about 4h of use.

Since there's already an upstream bug, I'm closing this one until it's resolved.
