Re: xorg crashes with xinerama + crashes with compsite and OpenGL
This has bitten me as well, in fact this is what I came to post about.
I'm running the newest xorg and nvidia driver in Ports as of today (7.3 and 173.14.09) on FreeBSD 7.0 i386 with two displays in TwinView. My configuration file has not changed, and everything worked perfectly with a previous release.
I was pulling my hair out trying to get GL apps working, so now I'm just running with Composite disabled and with Metacity instead of compiz. It wouldn't be so bad if the GL apps themselves just crashed, but it takes down my entire x server.
Edit: I installed ports-mgmt/portdowngrade, rolled back to 169.12 from April, and all is well.
