OK. These suggestions may just be shots in the dark; but... You might give Xorg -configure a try, to see if it might provide you with some hints as to what it *thinks* you have. I notice in your Xorg.0.log that X barfs on AIGLX. You might just try adding the following to the Section "ServerLayout" block: Option "AIGLX" "false" and see if that overcomes the problem. Hope this helps, and apologies for top posting. --Chris On Mon, 20 Mar 2017 13:59:16 -0500 Bob Willcox <bob@immure.com> wrote > On Mon, Mar 20, 2017 at 11:20:22AM -0700, Pete Wright wrote: > > > > > > On 03/20/17 11:15, Bob Willcox wrote: > > > On Mon, Mar 20, 2017 at 11:07:15AM -0700, Pete Wright wrote: > > >> > > >> On 03/20/17 11:04, Bob Willcox wrote: > > >>> I had to reboot my system this morning (power outage over the weekend > > >>> forced it) and now X won't start, failing with these error msgs from > > >>> the Xorg.log: > >>> > > >>> [ 143.327] (EE) open /dev/dri/card0: No such file or directory > > >>> [ 143.327] (WW) Falling back to old probe method for modesetting > > >>> [ 143.327] (EE) open /dev/dri/card0: No such file or directory > > >>> [ 143.327] (WW) Falling back to old probe method for scfb > > >>> [ 143.327] scfb trace: probe start > > >>> [ 143.327] (II) scfb(1): using default device > > >>> [ 143.327] scfb trace: probe done > > >>> [ 143.327] (WW) VGA arbiter: cannot open kernel arbiter, no > > >>> multi-card support [ 143.327] (EE) Screen 0 deleted because of no > > >>> matching config section.
