You don't include the salient bits of the actual X log showing the failure. So I'm gonna assume it's the same thing I've seen on 2 machines now, and somebody else mentions in Specifically, to take a bit of a handy Xorg.0.log from my workstation: [ 149.338] (EE). [ 149.338] (EE) Backtrace: [...] [ 149.354] (EE) 7: /usr/local/llvm39/lib/libLLVM-3.9.so (_ZN4llvm2cl6Option11addArgumentEv+0x7c) [0x809876e8c] [ 149.361] (EE) 8: /usr/local/llvm34/lib/libLLVM-3.4.so (_ZN4llvm16PPCTargetMachine17addAnalysisPassesERNS_6legacy15PassManagerBaseE+0x262) [0x80e3901e2] [...] [ 149.375] (EE) 22: /usr/local/bin/X (_start+0x17f) [0x42507f] [ 149.376] (EE) 23: ?

The first machine only had the LLVM 3.7 that X was previously using, and the new 3.9; uninstalling 3.7 made it just pick up working. On my workstation, I've got 3.4 onward all installed for testing some stuff, so when I temporarily uninstalled 3.4 after the above, it helpfully blew up on 3.5 instead. So I wound up having to stash away and pull off everything but 3.9, starting X, then re-installing them. Something in the X server is getting too durn adventurous looking for stuff to link in. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
