[Bug 382437] Re: Page slowly refreshes when set in Portrait

I note that you've got an nv5x card (Geforce 8 or above).  The 2d
acceleration on these cards only works when a compositing manager is
running (this has to do with VRAM tiling requirements).

If you're not running a compositing manager (not Compiz, which requires
3d, but Metacity's compositing manager, KWin's "XRender backend"
compositing manager, or xcompmgr), then this is expected behaviour for
the moment.  Without acceleration, rotation will be done entirely in
software, which, as you've found, is terribly slow, and Xv (the X Video
extension) won't work at all.
