I have just upgraded my desktop from fedora 25 to the recently released fedora 26. However following login which appears successful there is just a blank screen with a cursor in the middle that does not respond to the mouse.

I can boot with runlevel 3 into the terminal and my files are there. But I cannot boot normally into the Gnome desktop. Can anyone help with this? What information can I provide which might help to solve the problem?

open terminal, run lspci and lsmod. post the output of the commands, to your question, by editing the question. If you run nvidia, you may need to reinstall the driver. I run the proprietary 384.59 with dkms enabled, to take care of kernel updates.

try this, to see if you get a low resolution graphic desktop. When you start up, at the grub menu, before the countdown ends, press e on your keyboard. find the word quiet on the linux command line, and put nomodeset=0 in front of quiet then press Ctrl-X to boot. the grub change is temporary, but should give you a gui to use. then see if video drivers for the motherboard are available on the website.

Many thanks for taking the time to respond to this, much appreciated. Your suggestion of nomodeset=0 worked to give a low resolution display. The motherboard (Asus Z170-P ATX LG1151) has an integrated Intel hd graphics card. Where would you recommend looking for a driver? I guess this does not come with Fedora? Also I am wondering why this has been working in Fedora 24 and 25, but not 26.

perhaps the motherboard website would have a driver, or intel's website. showed the i916 driver being what f26 detected. offhand do you remember what f25 detected? it may be a bug in the f26 intel drivers. Do you have any F25 kernels on your grub menu, to boot into, and verify the diver file name and type of driver?

The problem is now solved, but I'm not sure exactly what I did to solve it. Many thanks to steveebey73742 for all the suggestions.

  • Check that intel driver that comes with Fedora is installed
  • Check if you can boot into previous Fedora kernel version
  • Boot with kernel option nomodeset=0 to get a low resolution graphical display
  • Do sudo dnf upgrade
