See NOTES for what +wayland is or maybe will be some day. + +Wayland requires the eagle EGL stack available from + + git://people.freedesktop.org/~krh/eagle + +and currently assumes that eagle is checked out in a sibling +directory, for example: + + ~krh/src/wayland and + ~krh/src/eagle + +Eagle should work with a recent DRI driver from mesa, but I have mesa +repo with an eagle branch here: + + git://people.freedesktop.org/~krh/mesa + +which provides and experimental DRI CopyBuffer extension, that lets +wayland use the DRI driver and the hardware for implementing buffer +swaps. Eagle needs to be compiled against the dri_interface.h from +this branch to be able to use the CopyBuffer extension. + +To run wayland you currently need intel hardware, a kernel with gem +and kernel modesetting, and it is necessary to set a couple of +environment variables. First, set LD_LIBRARY_PATH: + + export LD_LIBRARY_PATH=$PWD:$PWD/../eagle + +Yes, this sucks, but libtool sucks more. Then to let eagle pick up +the custom dri driver, set + + export EAGLE_DRIVER_PATH=$PWD/../mesa/lib + +and finally set up the path to the evdev device to use as a pointer +device: + + export WAYLAND_POINTER=/dev/by-id/whatever-it's-called-event-mouse + +If you haven't already, load the i915 driver with modesetting: + + modprobe i915 modeset=1 + +You may need to unload it first, if it's loaded already. Also, on +Fedora, there may be a bogus /etc/modprobe.d/i915modeset preventing +the modeset paramater from reaching the module. Nuke it. + +At this point you should be able to launch wayland and a couple of +clients. Try something like: + + ./wayland & + ./background <some png/jpg image smaller than 1024x768> & + ./flower & + ./flower & + ./flower & + ./window & + ./pointer & + +Maybe some day there'll be a script that does all this. Some day... + +And after all this work it may still not work or even oops your +kernel. It's very much work in progress, so be prepared. + +cheers, +Kristian |
