Revision as of 18:14, 29 June 2006

Some functions of the X.org server, such as 3D acceleration for newer cards, are under constant developments. To test the latest features, you need to build the X server and related software directly from the developers' CVS and GIT repositories. Since several projects and dozens of sub-projects are involved, this is a complicated task.

The following script automates fetching, compilation and installation of the following:

By default all compilation happens in ~/3d-pit and everything is installed into ~/3d-pit/install. The built DRM kernel module is installed to /lib/modules/.... No other paths are touched (but run as a non-root user, just in case).

To save time not all X libraries are built, so you'll need the usual X development environment packages installed (see above links).

Currently only the ATI radeon X.org drivers and r300 DRI driver are fetched and compiled. If you need different drivers, search for "radeon" and "r300" and modify as needed.

# Creating a script which sets env vars

export PATH="$DEST/bin:$PATH" 
export LD_LIBRARY_PATH=$DEST/lib
export LIBGL_DRIVERS_PATH=$DEST/lib/dri
EOF

echo "Run '. $DEST/bin/xsetenv' to point env vars to this installation."

Running

Just run the above. If prompted for a CVS password, press Enter. There are two sudo invocations for which you may need to provide a password.

Prepare a config file called (say) /etc/X11/xorg.dri-test.conf with DRI enabled.

Then, exit your current X server (e.g., via # init 3) and run something like: $ . ~/3d-pit/install/bin/xsetenv; X -config xorg.dri-test.conf :0 >& xout.log & ( export DISPLAY=:0; sleep 3; kwin& xterm& )

If all goes well, you'll get a minimal X session with just an xterm open. Some things to do now:

  • $ xdriinfo
  • $ LIBGL_DEBUG=verbose glxinfo 2>&1 | less
  • $ glxgears
  • $ sudo less ~3d-pit/install/var/log/Xorg.0.log
  • $ ppracer (and report on the associated bug including the relevant # lspci -v lines)
  • $ googleearth (Linux version here)

To keep up with the latest CVS and GIT versions, just run the script again. You don't need to (and shouldn't) delete ~/3d-pit beforehand.
