 +==== disable glamore ====
 +
 +in case dri crashes on x startup with Sementation fault (because mesa is compiled for another kernel) you can disable it.
 +
 +first check /var/log/Xorg.0.log for something like this:
 +
 +<code>
 +[ 26.398] (II) Loading sub module "glamoregl"
 +[ 26.398] (II) LoadModule: "glamoregl"
 +[ 26.399] (II) Loading /usr/lib/xorg/modules/libglamoregl.so
 +[ 26.424] (II) Module glamoregl: vendor="X.Org Foundation"
 +[ 26.424] compiled for 1.20.4, module version = 1.0.1
 +[ 26.424] ABI class: X.Org ANSI C Emulation, version 0.4
 +[ 26.829] (EE)
 +[ 26.830] (EE) Backtrace:
 +[ 26.830] (EE)
 +[ 26.830] (EE) Segmentation fault at address 0xbc
 +[ 26.830] (EE)
 +Fatal server error:
 +[ 26.830] (EE) Caught signal 11 (Segmentation fault). Server aborting
 +[ 26.830] (EE)
 +[ 26.831] (EE) 
 +</code>
 +
 +then create a file named /etc/X11/xorg.conf.d/00-noglamore.conf with following content:
 +
 +<code>
 +Section "Device"
 + Identifier "nogpu"
 + Driver "modesetting"
 + Option "Accelmethod" "none"
 +EndSection
 +
 +Section "Module"
 + Disable "glamoregl"
 +EndSection
 +</code>
 +
 +and then restart your display-manager (e.g. service lightdm restart)
