This is an interesting problem, I don't think anyone has tried that configuration before, and it exposes a limitation I wasn't previously aware of :-) > [ 1601.771] winAllocateFBShadowDDNL - Could not set cooperative level: > 88760245 > [ 1601.771] winFinishScreenInitFB - Could not allocate framebuffer > [ 1601.771] winScreenInit - winFinishScreenInit () failed > [ 1601.771] Fatal server error: InitOutput - Couldn't add screen 1 Error 88760245 is DDERR_EXCLUSIVEMODEALREADYSET At the moment, XWin always puts exclusive full-screen windows on monitor 0, so -fullscreen is only practically useful with a single X screen window, and this isn't going to work the way you want to. I think it could be made to work that way, but from a brief investigation it would require using a later version of the DirectX API than it's currently written to in order to put full-screen windows other than on monitor 0. For the moment, I think I shall add a fix so it doesn't crash when given this combination of options, and document this limitation to -fullscreen. As a workaround, I'd suggest you use -nodecoration instead of -fullscreen, which should be almost as good. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
