Summary: Workaround for lack of 8bpp (8-bit, 256 color) support on 24bpp displays Product: Wine Version: 0.9.30. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-x11driver AssignedTo: wine-bugs@winehq.org ReportedBy: cshore@wightman.ca
8bpp color (256 color mode) is not available if the X display is set to 24bpp color. This can be worked around using RealVNC 4 (vnc4server, xvnc4viewer) for sure and possibly TightVNC or RealVNC 3. With vnc4 if you use the parameter -cc 3 (e.g. vnc4server :2 -cc 3 -geometry 640x480 -localhost, then issue the command xvnc4viewer :2) you can have a virtual 8bpp display (in the example a 640x480 window with the virtual screen would appear). This is known as PseudoColor mode in the vnc documentation.
