How to implement so called 'network transparency' when DRI is enabled? (FreeNode: #freedesktop)

GLX is an X protocol extension for sending 3D instructions to the server  so... GLX can pass data without X server...?  no, it goes through the X server it's much much slower than DRI  and can i use AIGLX?  if you have AIGLX (accelerated, indirect GLX) then your X server itself can use DRI to draw the 3D stuff, but the fact it has to go from the client to the server before it goes to the hardware kills the performance indirect means the X server does it, direct means the client does it you can only do direct rendering when the client is running on the same machine as the hardware, and has access to the kernel's drm devices in /dev/drm sorry, /dev/dri <justin_lee> so AIGLX over nework should faster than GLX over network? will that sound good.... <Robot101> AIGLX is the only way to make GLX work on the server in Xorg - if you don't have it then mesa (the glx library) will fall back to software rendering, and the client will do it all and send pixmaps to the server, which will be hella slow... at least, I think I might be wrong, the server might do software rendering if there's no AIGLX, but it'll still be slow <justin_lee> it sounds good at least the network transparency is preserved so that i can use XDMCP to connect the remote desktop <Robot101> yes, network tranparency will continue to work, it'll just be really slow (if it's doing software rendering) or pretty slow (if it's doing AIGLX) <justin_lee> and... network tranparency work under DRI2? because DRI seems not to support compositing desktop such as Compiz fusion etc... <Robot101> doesn't matter, the network transparency is done at the X level, not the DRI level I think if you use a compositor and don't have DRI, it will be unusably slow if it works at all, in fact Robot101 robtaylor Robot101 robtaylor <justin_lee> Robot101: excuse me, are you really a bot? <Robot101> what do you think? <justin_lee> well not likely, a bot should not be able to give such a excellent answer Robot101: thank you very much <Robot101> correct! :) you've passed today's turing test <justin_lee> Robot101: it's very helpful in order to give me a clear concept :) --> kov (n=kov@debian/developer/kov) 加入了 #freedesktop Robot101 robtaylor <Robot101> just got some info from a friend: in the case of GLX and there's no DRI support on the server, then the server will usually use Mesa to do software rendering <justin_lee> Robot101: well, that will be painfully slow Robot101: have a good day and thanks again :-) <Robot101> the difference between DRI and GLX will already cause you a lot of pain <justin_lee> yep, and it gets me headache
