<p>Nicolbolas: added EyeFinity support status</p> <hr /> <div>== Screen Rotation ==<br /> On Catalyst 8.9 and later ATI drivers now support RandR rotation. After configuring your ati card as usual enter the following command:<br /> &lt;pre&gt;<br /> aticonfig --set-pcs-str=&quot;DDX,EnableRandr12,TRUE&quot;<br /> &lt;/pre&gt;<br /> <br /> Then restart X11. Your xrandr should work.<br /> <br /> 2010-10-27: xrandr works on my Mobility Radeon HD 5730 with Catalyst 10.9 driver without needing to run the command above. I just tried &lt;pre&gt;xrandr --orientation left&lt;/pre&gt; and the screen rotated onto its side.<br /> <br /> Note: Using this command on a Radeon Xpress 200M made Xorg unable to start with some weird error in the amdxmm module. Using this command with FALSE instead of TRUE helped afterward.<br /> Note: I also had a problem with that option with a 4850, I couldn't get Xorg to start after setting that option.<br /> <br /> Q: Is rotation hardware accelerated? How does performance compare to non-rotated?<br /> <br /> R: On 10.12 (probably sooner), rotation is fully hardware accelerated. Either video buffering or 3d rendering show no slowdonws even across rotated and non-rotated screens.<br /> <br /> == Open Source Drivers ==<br /> <br /> ATI Radeon cards 8500,9000,9200 and 9250 working with [[open source drivers]] provide OpenGL 3D graphics acceleration.<br /> <br /> == Proprietary Drivers ==<br /> <br /> Proprietary drivers can be used instead, if so desired, although it is not necessary to use these for the cards listed above.<br /> <br /> ==2D==<br /> ===X server===<br /> *XFree86 and X.org support<br /> ====Xaa====<br /> *X Acceleration Architecture<br /> ====Xv====<br /> * One Hardware or OpenGL overlay<br /> <br /> ===TV Out===<br /> *NTSC and PAL support<br /> <br /> ==TV In==<br /> *No support for the built in tuner in &quot;All-in-Wonder&quot; cards.<br /> <br /> ==3D==<br /> ===OpenGL===<br /> *Provides some OpenGL 2.0 commands <br /> BUT NOT <br /> the OpenGL 2.0 version of the shading language.<br /> <br /> The ATI driver uses a version of the shading language called<br /> the ARB extension.

It's often best to adjust screen alignement using the &quot;Position +x +y&quot; option in xorg.conf.'''<br /> <br /> '''EyeFinity support is still messy''' : As of 10.12, Five display setup on a HD5770 Eyefinity5 edition cannot be used. In any case, at least one display out show a scrambled image (with a neat cursor and correct placement).<br /> <br /> <br /> [[Category:NeedsUpdating]]</div>
