I updated to Centos 6.8. Every thing is working, except Xorg does not startup. When I look at top, it seems that Xorg keeps trying but not succeeding to start. Any idea what the problem might be? Thanks Shoshana Rosenthal srosenthal at cfa.harvard.edu

In my case the problem stemmed from the fact that my machine has a MACH64 video card. The updated Xorg has a reference xf86LinearVidMem. I opened bug 1422622 at bugzilla.redhat.com. This was on 2/15/2017. So far the bug is just sitting there. My work around was to disable the main repo's in /etc/yum.repos.d and enable 6.7 in the vault repo. Did a distribution synchronization. Here are the notes from what worked: (may be line wrapping issues in what follows) Went back to the x64 version and figured out how to roll back to 6.7: mount -t nfs phxbkup2:/iso/centos6.7x64 /media/CentOS # This one failed with dependency issues yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 distribution-synchronization # Erased the problem packages yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 erase python-libipa_hbac-1.13.3-22.el6_8.4.x86_64 mesa-libxatracker-11.0.7-4.el6.x86_64 xorg-x11-drivers-7.3-13.4.el6.x86_64 mesa-libxatracker-11.0.7-4.el6.x86_64 yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 erase xcb-util xcb-util-renderutil # Now it worked yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 distribution-synchronization # put pack the drivers yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 install xorg-x11-drivers yum --disablerepo=\* --enablerepo=c6-media --releasever=6.7 install python-libipa_hbac mesa-libxatracker mesa-libxatracker # These not available on the media and not reinstalled. python-libipa_hbac mesa-libxatracker mesa-libxatracker # Now it worked.

If so, my first thought would be to tell it init 3, to multiuser mode without X running, and then run startx, and see if it gives you any useful messages. /var/log/Xorg.x.log is extremely difficult to find useful information, unless in the last few lines you find an EE message. mark
Thanks for responding. I really don't know why I have the problem my computer is a Dell computer with the standard parts. I am not sure that your fix will work for me. I am using the computer remotely and am still looking for a solution.
