Rotation was originally done to satisfy customers doing signage who didn't care about high performance.
Here's a response from the engineer who worked on this:
I'm not on the list, I'll let you respond. Yes, it is expected behavior. Anything other than normal, side by side, non-rotated Outputs will result in a shadow framebuffer being used, and all rendering optimizations disabled. Even on the non-rotated Output, as dual-monitor DTU's look like a single framebuffer to Xnewt.

Hello, I'm currently playing with the Xrandr rotation features in SRS 5.2 and have run into a performance issue. Here's my configuration: Sun Ray 2FS DVI1 = 1680x1050 LCD DVI2 = 1680x1050 LCD What I'm trying to do is rotate the LCD on DVI2 to the left and keep DVI1 normal. I issue: /opt/SUNWut/bin/xrandr --output DVI2 --rotate left ..and the monitor rotates. Only issue is that performance on both monitors is SLOW (choppy, etc). Rotating DVI2 back to normal results in good performance. Anyone have an idea what is going on? Is this something that should be working the way I expect? -Jon _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
