The frame-buffer scaling is specific to Etoys. It traditionally uses its own OS-independent frame-buffer, rather than GTK/Cairo as the other activities do.
Ideally someone would patch Qemu to allow a 1200x900 resolution. In theory that would simply require adding a 1200x900x16 mode to the VESA mode list. Having that resolution would go a long way already, but adding scaling (even if by a fixed factor of 0.5) would make it an even better emulation environment. - Bert - On Nov 12, 2007, at 1:32 , Michael Vorburger wrote: > > and etoys uses framebuffer scaling to emulate the XO's native > 1200x900 resolution. > > Hallo Bert, > > How does this work, and Is it specific to the etoys Activity or > would there be a way to configure this in a qemu image for X and > Sugar all activities?
