Note that the 1.0.0 release did not have SIMD acceleration for x86_64, so you might want to try checking out a copy from svn. Or building it on a 32-bit machine. > > The bugs: > > 1.

What component are you using here? I'm assuming x0vncserver or libvnc.so as you're referring to :0. Sounds like the latter though. We rewrote a lot of that code to get randr support, but it was more or less only tested with Xvnc. I don't think anyone here has time to look at it though, but you could have a look at it yourself if you feel up for it. Relevant sections are vncHooksRandRSetConfig() in vncHooks.cc and XserverDesktop() in XserverDesktop.cc. Those are the two places where it gets the screen size. > > 2.

Something must be horribly wrong there. Is it eating a lot of CPU on the client or server when doing this? Even if it's picking a high bandwidth option (because of the misdetection) then it should only be a matter of seconds at most to redraw a screen.
