Also doing alt-f# and control-w and such when using vnc is getting VERY irretating, since vinegra takes control-w to mean close current connection, while I want it sent through to delete work, or do other things. xvnc4viewer doesn't grab focus properly, and won't sent alt+f# through, so my window manager still sees those. All these work fine with running it through a forwarded X connection, except the 6336 change made that unusable. VNC mode is a pain in the ass, although very efficient protocol wise. > > Of course if it is slow even locally, then there must be something wrong > > somewhere either in qemu or in sdl. > > Well I wasn't the one that saw it slow locally. > > Now does the change in 6336 make it faster on the local side for some > people? if so, then I guess there is some potential there. > > Is there some environment that can be set to tell SDL what driver to use > and how to behave? -- Len Sorensen
