I have installed in my Zenbook the new version of Fedora 26 with Cinnamon desktop. After a clean installation, login screen go to software render mode.

My system is updated.

I have try to update intel drivers from official page. It seems it doesnt support Fedora 26. Changing /etc/fedora-release for 25 version, updating, rebooting, and restoring /etc/fedora-release again doesnt work.

If I modify grub entry adding init 3, and start in terminal mode, try to reconfigure X using X -configure I get this error:

X.Org X Server 1.19.3 Release Date: 2017-03-15 X Protocol Version 11, Revision 0 Build ... (more)

You do not see a driver listed in lshw so I would check there, and see if the intel driver has a problem. Check the website for the computer, to see if they have drivers.

I have tried but it seems no official support to Fedora 26. In fedora 25 worked propertly.

iGPU in i7-6500U should be working fine out of the box, without drivers from .

Try creating fresh USB flash drive with Fedora 26 Cinnamon. Make sure you verify .iso file checksum or use Fedora Media Writer in current system to download and write image to USB. After you boot from it, login and open terminal (Ctrl+Alt+T) and run




and paste their output here using

If Cinnamon will work there fine in hardware rendering mode then your installation is corrupted and fresh install will help, otherwise it might be a hardware issue.

In other computer I did the following steps:

I installed with dnf liveusb-creator.
I download manually version Fedora Cinnamon Desktop Intel 64 bits and check checksum against
Using: sha256sum Fedora-Cinnamon-Live-x86_64-26-1.5.iso Result is: 47b3a500a9d09423cf40141e006a4ab80633856266b49494300f7686a259debe Fedora-Cinnamon-Live-x86_64-26-1.5.iso so seems ok.
I create live USB using mediawriter.
a) Booting USB Live, start Fedora Live: Black screen, desktop sounds so initialize, but I cannot see the framebuffer or go into a console with Control + alt + Number.

b) Troubleshoot > Basic graphic mode: Works in software render mode
    Running command glxinfo result:
    Running command dmesg Outputs at:

So it's not a corrupted installation if fresh bootable USB also doesn't work in normal mode. You can boot Fedora 25 from USB to check if it's not just a recent regression.

Post here also dmesg output and /var/log/Xorg.0.log from your installed Fedora 26.

P.S. You can use sha256 -c checksum_file to verify checksums, just keep both files in the same directory.

After wait for an update of the kernel that not fixed the problem. Try to compile by my own the kernel 4.13 from kernel repository. Several tries with custom kernels from Fedora fedpkg, I realized that the problem was another.

It seems like in some models Zenbook, that problem said by ozeszty, fails in i915 graphic driver. I installed a clean Fedora 26 version using low graphic boot, because in normal mode the screen appear in black (but some sound at the boot indicated the S.O was loaded)

From sudo dmidecode | less I get that my model is

BIOS Information
        Vendor: American Megatrends Inc.
        Version: UX305UA.201
        Release Date: 10/12/2015

The Xorg -configure command fails to execute but log indicate that i915 is the correct drivers. But checking initial Xorg log, VGA graphic drivers is loaded, that explain the low graphic mode. To solve this, is needed to force the load at boot time.

The clue of the problem was given using the command cat /sys/module/i915/parameters/modeset, where the output is -1, I got it from this post.

So changing grub initialization in grub setting files at: /etc/default/grub, forcing original line to load i915 module, from: GRUB_CMDLINE_LINUX=" nomodeset rhgb quiet" to GRUB_CMDLINE_LINUX=" nomodeset rhgb i915.modeset=1", and updating with command grub2-mkconfig -o /boot/grub2/grub.cfg, at last, rebooting the computer fixed the problem. (I removed the quiet because I prefer to see more logs :p)

Thanks to sparacuellos for helping me to find the problem, and the people who try in the post. I hope this help if someone else have the same problem.

If you are not presented with a login screen after turning your computer on, then sign out (you may want to create a non-root user for safer usage, if this is what happens).

Once you have either signed out, or you are presented with a login screen when you power your computer on, then look at the box that has the rectangular button that says "Login".

Within the same box that contains the rectangular button that says "Login", look directly above that rectangular button that says "Login", but on the right hand side. There should be a small icon.

The little icon to the right, that is directly above the rectangular button that says "Login", is what allows you to choose your desktop.

Click the button.

You should be able to select one of three options.

If you were already aware of this, then I apologize for trying to be as descriptive as I have in this post. I just got this distribution yesterday and like it MUCH more than Windows 10. I backed it up and installed this in its place.

You may want to run dnf update (I ran it using zsh and it upgraded everything automatically after updating). My only guess is that maybe you have some hardware not fully supported yet, seeing as how you've got a really decent computer, which is why I would run the update if you already knew about the icon above the "Login" button.
