Are you talking about a monitor that is able to change its beam scanning, or are you talking about rotating a normal monitor, so that the beam scans from top-to-bottom? In the first case, almost any graphics card should be able to set up a 768x1024 mode for a standard monitor. However, the second case requires a graphics chip that knows how to scan its frame buffer differently. I know of very few chips with that ability, and a software simulation will always be unsatisfactory. The application is to mount a Plasma screen on its side. Which means the software simulation. We have tested on Windows and the i810 driver costs about 20% extra on a 2.4GHz P4 CPU to run portrait and play a movie. So it is possible to do reasonable cost. However using the ShadowBF under X the performance is, as you say, unsatisfactory. We have not found a portrait mode plasma screens yet, but that seems like the solution we need to look for, we do not want to use Windows.

If the only thing to be shown rotated is a movie, you could consider using rotation in the movie player. However, I am not sure how efficient this is, so this needs testing. -- Rafa Rzepecki ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
