Revision history [back]

I had the same issue - though in my case I'm running a Skylake i7-6700 CPU

Logged in under normal Gnome X Server i also had the issue that in the display applet my monitor was not detected correctly (showed as unknown) and I could not change the resolution (only one resolution shown)

in a terminal running 'glxinfo | grep OpenGL' the output showed: renderer = Gallium 0.4 on llvmpipe (LLVM 3.7, 256 bits) rather than: renderer = Mesa DRI Intel(R) Skylake DT GT2

Hunting around I eventually resolved this by updating grub to include 'i915.preliminary_hw_support=1'

i.e in a terminal run:

  1. su (to escalate to root)
  2. dnf install grub-customizer
  3. Open Grub-Customizer and under 'General Settings' tab add under 'kernel parameters': i915.preliminary_hw_support=1
  4. Save and exit
  5. in terminal run: grub2-mkconfig -o /boot/grub2/grub.cfg
  6. (I had to do the above to apply the grub-customizer change to the actual grub config - not sure if this is normal or to do with the fact i'm running EFI system)
  7. reboot
  8. in terminal run: glxinfo | grep OpenGL - if you now see 'renderer = Mesa DRI Intel.....' then you should be able to login to Wayland desktop

Note: after the above my monitor was correctly detected and i could change resolution as well
