I made a 2nd wayland build: OK, there is definitely a problem with $DISPLAY, if I use a different one (for example DISPLAY=:1.0), I get "failed to create compositor". If I want to use DISPLAY=:0.0, the error-message is "failed to initialize display" ending with a Segmentation fault. Having a look into dmesg: [ 61.979227] lt-compositor[1702]: segfault at 30 ip 0804db9e sp bf8d2bd0 error 4 in lt-compositor[8048000+a000] That's saying not much to me. How can I dig deeper into the problem? Use and create packages with debug symbols I guess? For mesa I know there is --debug. Enable debug-build for cairo-gl and wayland? Any suggestions for Linux kernel-config parameters to better debug Wayland? - Sedat - $ echo $DISPLAY :0.0 $ cd $HOME/src/wayland/wayland/compositor $ LC_ALL=C ; LIBGL_DRIVERS_PATH=/opt/wayland/lib/dri DISPLAY=:1.0 ./compositor -b ../../backgrounds/dscn1843.jpg failed to create compositor $ LC_ALL=C ; LIBGL_DRIVERS_PATH=/opt/wayland/lib/dri DISPLAY=:0.0 ./compositor -b ../../backgrounds/dscn1843.jpg failed to initialize display Segmentation fault $ dmesg | tail -10 [ 21.151574] Bluetooth: RFCOMM socket layer initialized [ 21.151577] Bluetooth: RFCOMM ver 1.11 [ 21.156060] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 21.156064] Bluetooth: BNEP filters: protocol multicast [ 21.350328] Bluetooth: SCO (Voice Link) ver 0.6 [ 21.350333] Bluetooth: SCO socket layer initialized [ 29.904036] wlan0: no IPv6 routers present [ 61.979227] lt-compositor[1702]: segfault at 30 ip 0804db9e sp bf8d2bd0 error 4 in lt-compositor[8048000+a000] [ 152.636425] lt-compositor[1768]: segfault at 30 ip 0804db9e sp bf9e7f30 error 4 in lt-compositor[8048000+a000] [ 197.229767] lt-compositor[1803]: segfault at 30 ip 0804db9e sp bffb9330 error 4 in lt-compositor[8048000+a000] _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
