However there was nothing to file against in /var/crashes] For certain games I disable the Composite extension in my /etc/X11/xorg.conf when using a non-composited window manager like openbox, fluxbox or marco. Disabling the Composite extension prevents tearing in (some) games and sometimes is an additional performance boost. This worked flawlessly in all previous Ubuntu versions including 17.10 (artful). This stopped working with Ubuntu 18.04 (bionic). I tested with the mainline kernel 4.16 and the current 4.15 kernel in bionic-proposed and bionic. Xserver will crash with "Option "Composite" "0/False/Disable" When I comment out the specific line in the Extensions section (that means *enabling* Composite) it works again with this xorg.conf. I can also do other stuff like disabling DRI3 or AIGLX. No crashes in these cases. My xorg.conf: Section "Device" Identifier "Intel GMA45" ##just a trivial name as Identifier Driver "intel" EndSection Section "Extensions" Option "Composite" "0" EndSection It has a backtrace and caughts signal 6.
