Was this intended? This will force indirect rendering. > + <p>If the problem is reproducible with indirect rendering, then there is > + likely a problem with the GL library itself. Actually, more likely with the OpenGL/GLX implementation in the X server, i.e. in paractice, most likely in the Mesa code shared between the X server and the DRI 3D drivers. > + <p>On the other hand, if the problem goes away when indirect rendering is > + used, then one of the following is at fault:</p> > + <ul> > + <li>the hardware-neutral parts of DRI</li> Apparently, when it says 'hardware-neutral parts of DRI', it really means 'X server parts of the DRI' (which aren't necessarily hardware-neutral)? > + <p>To rule out problems with the hardware-neutral parts of DRI, remove > the > + <code class="package">xlibmesa-dri</code> package if it is installed, and > + disable the <code class="other">Load "dri"</code> line in your <code > + class="filespec">/etc/X11/XF86Config-4</code> file. Only the latter is really required for this, the (non-)presence of the former doesn't matter if the DRI is disabled in the X server. -- Earthling Michel DÃnzer | Debian (powerpc), X and DRI developer Libre software enthusiast | http://svcs.affero.net/rm.php?r=daenzer
