[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Add Summagraphics Tablet emulation for VNC users. The current PS/2 emulation
# HG changeset patch
# User kaf24@xxxxxxxxxxxxxxxxxxxx
# Node ID 58d1ef21570698669176adfe90ebb6bc4cd3c8d1
# Parent d6bab69e856fe72cbaa4008285ed529954d1c3a9
Add Summagraphics Tablet emulation for VNC users. The current PS/2 emulation
is unusable under VNC since a PS/2 mouse provides deltas while VNC only
provides absolute coordinates. Fortunately, the Summagraphics Tablet provides
absolute coordinates and works perfectly with VNC.
