Package: xserver-xorg-video-savage
Version: 1:2.0.2.3-4
Severity: wishlist
Tags: patch

Getting DRI working with the Savage driver in this package is not
documented very well. The main problem I had was that I had not
installed libgl1-mesa-dri, which contains savage_dri.so that is
necessary for DRI acceleration. I would like to add a Suggests: on this
package to control, and I have also documented how to debug these
problems in a new README.Debian for this package. Please could you
consider adding this to the package?

I haven't made libgl1-mesa-dri a Recommends: because it is quite a large
package, and xserver-xorg-video-savage is often installed on machines
where it is not needed.

+3D acceleration using Savage drivers
+------------------------------------
+
+If 3D acceleration is working, glxinfo (in package mesa-utils) will report:
+  
+  direct rendering: Yes
+
+Also, in your X server log (/var/log/Xorg.0.log)  you will find:
+
+  (**) SAVAGE(0): DRI is enabled
+
+
+Troubleshooting 3D acceleration with Savage drivers
+---------------------------------------------------
+
+If can not find this in your X server log:
+
+   (**) SAVAGE(0): DRI is enabled
+
+You should check that your X server really is using the Savage driver, and that
+X acceleration is not disabled. You should find a device section like this in
+/etc/X11/xorg.conf:
+
+Section "Device"
+        Identifier      "S3"
+        Driver          "savage"
+EndSection
+
+If the X server log shows that DRI is disabled, but glxinfo reports that direct
+rendering is not working, you should check that libgl1-mesa-dri is installed.
+This package contains the savage_dri.so DRI module which is needed for direct
+rendering.  If this is installed, look at the output of glxinfo with debug
+information enabled. On a working system you should see something like this:
+
+$ LIBGL_DEBUG=verbose glxinfo
+
+name of display: :0.0
+libGL: XF86DRIGetClientDriverName: 2.0.2 savage (screen 0)
+libGL: OpenDriver: trying /usr/lib/dri/savage_dri.so
+drmOpenByBusid: Searching for BusID pci:0000:01:00.0

+libGL error:

+libGL error:

As explained earlier, we just need to update the global Debian-Xorg FAQ
and bring it back in one package. We have some other bug reports about
this. No need to keep this one, there's nothing specific to Savage. Thanks.
