RHBZ 1650634 is of no help to me,X fails to start on certain systems with an Nvidia card See RHBZ 1650634.
e.g.
Does not fix it for meIf I run this command:
yum downgrade xorg-x11-drv-nouveau xorg-x11-server-Xorg xorg-x11-drv-qxl.x86_64 xorg-x11-drv-vesa xorg-x11-drv-dummy xorg-x11-drv-v4l xorg-x11-drv-ati xorg-x11-drv-vmware xorg-x11-drv-fbdev xorg-x11-drv-intel.x86_64
and reboot X starts back up again as expected.
Another solution:
I would rather not do that. I don't want to do this manually every time I update..Bug resolved by rebuilding xorg-x11-server-1.20.3-1.fc29 [1] for 7.6.
Other solutions.. ???
Why was 7.6 even released with such a big bug and no proper workaround?
