xgl. I'm running Ubuntu Dapper on an
AMD64 machine with an ATI card but hopefully this guide will be helpful
to others as well.
Start out by grabbing David Reveman's tarball from http://freedesktop.org/~davidr/xgl-svn_100.tar.bz2 .
You will also need most of the x11 development packages. The ones I have installed on my machine are
libx11-6 libx11-dev libxau-dev libxau6 libxcomposite-dev libxcomposite1 libxcursor-dev libxcursor1 libxdamage-dev libxdamage1 libxdmcp-dev libxdmcp6 libxext-dev libxext6 libxfixes-dev libxfixes3 libxfont-dev libxfont1 libxft-dev libxft2 libxi-dev libxi6 libxinerama-dev libxinerama1 libxkbfile-dev libxkbfile1 libxklavier10 libxmu-dev libxmu-headers libxmu6 libxmuu-dev libxmuu1 libxp6 libxpm-dev libxpm4 libxrandr-dev libxrandr2 libxrender-dev libxrender1 libxres1 libxss1 libxt-dev libxt6 libxtrap-dev libxtrap6 libxtst-dev libxtst6 libxv-dev libxv1 libxvmc1 libxxf86dga1 libxxf86misc1 libxxf86vm1 x11proto-bigreqs-dev x11proto-composite-dev x11proto-core-dev x11proto-damage-dev x11proto-fixes-dev x11proto-fonts-dev x11proto-input-dev x11proto-kb-dev x11proto-randr-dev x11proto-record-dev x11proto-render-dev x11proto-resource-dev x11proto-scrnsaver-dev x11proto-trap-dev x11proto-video-dev x11proto-xcmisc-dev x11proto-xext-dev x11proto-xinerama-dev
Now unpack the tarball and do
cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/xorg login cvs -z3 -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/xorg co app/glxcomp cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/cairo login cvs -z3 -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/cairo co glitz cd glitz ./autogen.sh --prefix=/opt/fdo make sudo make install
cd ../app/glxcomp ./autogen.sh --prefix=/opt/fdo make sudo make install export PKG_CONFIG_PATH=/opt/fdo/lib/pkgconfig
cd ../../Xserver-6.6.1 ./configure --enable-xglserver --enable-glx --enable-xkb --disable-kdriveserver make sudo make install
Now run Xgl and Metacity with
Xgl :1 -fullscreen -ac -accel xv:pbuffer -accel glx:pbuffer & DISPLAY=:1 metacity &
I've been told that those of you with nvidia cards should use
Xgl :1 -fullscreen -ac -accel xv -accel glx &
instead.
As explained by Hanno Böck, glxcompmgr needs the mesa libGL rather than the ATI version. Therefore, create some directory where your linker will not look, such as /opt/mesalibs and do
cd /opt/mesalibs cp /usr/lib/fglrx/libGL.so.1.2.xlibmesa libGL.so.1.2 ln -s libGL.so.1 libGL.so ln -s libGL.so.1 libGL.so.1.2
The preceding steps assume that you installed the ATI drivers through
the Ubuntu package xorg-driver-fglrx. If you just downloaded the
drivers from the ATI web site, your Mesa libGL will probably not be
named libGL.so.1.2.xlibmesa and could have been overwritten by the ATI
installation. In that case, you'll need to extract the drivers from
the package libgl1-mesa.
Now open a terminal in your Xgl window:
LD_LIBRARY_PATH=/opt/mesalibs DISPLAY=:1 gnome-terminal &
From this terminal, type
/opt/fdo/bin/glxcompmgr shadow wobble &
and glxcompmgr will hopefully start. If it bails out with an error message like "GLX_MESA_render_texture is missing", it did not find your mesa libGL and is still using the ATI version.
Happy Xgl'ing!
