Well I'm not 100% sure but as it states quite clearly on the intellinuxgraphics site's release notes from a week or two back that shatter is still going to be the solution here, I'm inferring that it'll ultimately work with UXA... if that's wrong, sorry for the FUD or at lease for the U bit :p Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mandriva Linux Contributor [http://www.mandriva.com/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/] ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Sure about that?

I suspect this may be the case considering the info on intellinuxgraphics.org site which specifically mentions shatter for the first time. Shatter looks neat (first time I hear about it), but is there perhaps a more immediate workaround? It used to work, just a week ago. Tamas Hmm, the abstract for the Linux Plumbers Conference paper to be presented in September claims Shatter is an EXA extension and IntelLinuxGraphics 2.8 dropped EXA support. Doesn't sound like it'll help the 945 guys after all! :-) Mike McDonald ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
