Adaptation/N9-N950/Wayland

Introduction

Some basic instructions for trying out Wayland on Nemo on N9/N950. These instructions will get simpler over time. If you need help with it, ask me (w00t) on IRC.

   [11:16:53] <w00t> ssu ar wayland http://repo.merproject.org/obs/home:/w00t:/branches:/nemo:/devel:/hw:/ti:/omap3:/n9xx-common/latest_armv7hl/
   [11:16:56] <w00t> ssu ur
   [11:16:58] <w00t> zypper ref -f wayland
   [11:17:11] <w00t> zypper up ti-omap3-sgx # don't say yes or no here yet, tell me what it says first
   [11:18:25] <Vesuri> let's see
   [11:19:36] <Vesuri> The following NEW packages are going to be installed:
   [11:19:36] <Vesuri> ti-omap3-sgx-wayland-wsegl wayland
   [11:19:37] <Vesuri> The following package is going to be upgraded:
   [11:19:38] <Vesuri> ti-omap3-sgx
   [11:19:53] <w00t> excellent
   [11:19:56] <w00t> yes, go ahead with that
   [11:20:05] <Vesuri> okay, that's done
   [11:20:18] <w00t> now reboot your device and make sure it starts the existing user session
   [11:20:43] <w00t> (it won't use wayland until we modify powervr's ini file, and ideally, we haven't broken x11 with this :))
   [11:24:09] <Vesuri> rebooted, looks good
   [11:24:17] <w00t> \o/
   [11:24:18] <w00t> ok.. sec
   [11:24:28] <w00t> open /etc/powervr.ini as root
   [11:24:40] <w00t> in '[default]' section, add: WindowSystem=/usr/lib/waylandwsegl.so
   [11:25:06] <w00t> zypper in qt5-qtwayland-wayland_egl-examples qt5-plugin-imageformat-jpeg qt5-plugin-platform-eglfs qt5-qtsvg-plugin-imageformat-svg
   [11:25:44] <w00t> systemctl stop user-session@1000.service
   [11:26:07] <w00t> cd /usr/lib/qt5/examples/qtwayland/qml-compositor/
   [11:26:27] <w00t> QT_QPA_EGLFS_DEPTH=16 WSEGL_DEBUG=5 QT_COMPOSITOR_NEGATE_INVERTED_Y=1 ./qml-compositor -platform eglfs
   [11:29:27] <Vesuri> oh yeah, can see the qml compositor screen
   [11:29:35] <w00t> \o/
   [11:29:42] <w00t> now.. you should be able to start a simple client
   [11:29:50] <w00t> let me get you minimer (i should really just package the damn thing)
   [11:29:54] <Vesuri> I have it
   [11:29:56] <w00t> oh
   [11:29:58] <w00t> excellent
   [11:30:15] <w00t> WAYLAND_DEBUG=1 QT_WAYLAND_DISABLE_WINDOWDECORATION=1 QT_QPA_EGLFS_HIDECURSOR=1 /usr/lib/qt5/bin/qmlscene -platform wayland /home/nemo/minimer/main.qml
   [11:34:33] <w00t> some fair warnings:
   [11:34:45] <w00t> performance is not going to be great, you can expect around 40fps fairly consistently
   [11:34:58] <w00t> (it's always in composited mode, there is no direct rendering at this stage, maybe ever)
   [11:35:39] <w00t> i also fully expect some crashes/etc when running things, i've even seen the odd one when interacting with qml compositor for instance.. backtraces are useful if you can get them
