Since about kernel version 4.15 - 4.16 something my IVY bridge machine has failed to display anything on the display with X and gnome running. everything is running X0rg says modesetting is not working.
The logs would say modeset failed. After a few attempts this modeset work work and I could get output on the display. But I had to use a worked arounding. I managed to work around this by enabling FB_EMULATION or whateve the i915 code that creates a framebuffer until kernel version 4.17.5. Since this version, nothing can get modesetting to work on this machine.
