Moving windows is always be somewhat slow (by design) without a compositing manager. > Even just scrolling through a text file in a terminal window looks very > slow. > > Is there any known issues with the Radeon HD 3200 under opensolaris Xorg > or is > there anything I can do to fix this ? > What display driver should be used for this graphics chip set? radeon OR radeonhd should both work (yes, there are two different drivers for the same hardware).

Unfortunately, nobody has ported a current DRM for the Radeon chips yet so the situation is unlikely to improve in the near future. You're using radeon now, it's worth trying the other driver first. There are some options that should improve 2D performance, like setting "AccelMethod" to "EXA" (see radeon(7) and radeonhd(7)). -Albert _______________________________________________ xwin-discuss mailing list [email protected] List info: http://mail.opensolaris.org/mailman/listinfo/xwin-discuss Unsubscribe: http://mail.opensolaris.org/mailman/options/xwin-discuss
