This probably isn't a help, but just in case...<br>
<br>
Also check the xorg conf file and syslog for which driver it's using (it often autodetects nowadays, and picks from among applicable installed drivers).<br>
<br>
In addition to which driver it's picking up, also check for whether it was able to load any device firmware blob or secondary (closed source) shared library.<br>
<br>
(Incidentally, I've actually noticed better 2D behavior overall from the open-source driver for my old Radeon laptop, except for video scaling.)<br>
<br>
Also maybe restart the xorg server or reboot. I don't know give that advice, and I don't know the xorg internals, but occasionally (esp. with closed driver) I have noticed performance behavior that seems like the server might be bogged down with cached pixmaps or similar. I've seen this with Firefox.<br>
