Hi, In an attempt to test out AIGLX, I upgraded to Mesa and xorg-server from cvs. Unfortunately, attempting to start X using the xorg-server built from cvs results in a hard lock of my computer. Mesa does not seem to be the problem, because if I downgrade back 1.0., leaving everything else the same, I have no problems. Over the course of playing with a few patches and such, I did at one point manage to get it where it doesn't hard lock the whole computer, just consumes 100% of the cpu and never finishes starting. When that happened, I was at least able to ssh in and see, but I couldn't find any incantations to kill X besides 'reboot.' It did, at least, leave a full log behind (the others get cut off). Sorry if I'm rambling a bit. I've tried just about everything I can think of, so if anyone has any suggestions, I'd appreciate it. Xorg log and conf below (I'm starting with the "Single" layout). <a href="http://s88382932.onlinehome.us/files/Xorg.0.log-aiglx">http://s88382932.onlinehome.us/files/Xorg.0.log-aiglx</a> <a href="http://s88382932.onlinehome.us/files/xorg.conf">http://s88382932.onlinehome.us/files/xorg.conf </a> Thanks, Ricky P.S. I'm using Gentoo, if that matters, with an xorg-server ebuild of my own crafting.
