xorg-server-1.4.2 + kmem + grsecurity (amd64)

[SlashBeast]

Hi, I have the same problem like this viewtopic.php?f=3&t=1149 but on never version Xorg and intel gma X3100 card.
My grsec is grsec-2.1.12-2.6.27.7-200811201849.pattch from hardened-sources (gentoo)

Code: Select all

Xorg says:
xf86MapVidMem: Could not mmap framebuffer (0xe4600000,0x80000) (Operation not permitted)


Code: Select all

In logs:
Nov 26 15:22:51 mizore [  503.031134] grsec: denied mmap write of /dev/[k]mem by /usr/bin/Xorg[X:5232] uid/euid:1000/0 gid/egid:100/100, parent /usr/bin/xinit[xinit:5231] uid/euid:1000/1000 gid/egid:100/100
