The Problem

How should I configure Xorg for an intel integrated graphics card under Fedora 25?

My motherboard and i7-6700K are supposed to support a dual monitor setup, but Xorg (or is it Wayland?) fails to detect the hardware on a level where this is possible. It seems to be using a VESA driver.

There are some smaller issues such as the system locking up when I change video modes (Xorg -> terminal). I assume these will be corrected by fixing the driver problem(s). There are some forum posts about adjusting BIOS settings or setting i915.enable_rc6=0 - I will worry about this later.

System Information

$ cat /etc/fedora-release

Fedora release 25 (Twenty Five)

$ uname -a

Linux shogun 4.8.15-300.fc25.x86_64 #1 SMP Thu Dec 15 23:10:23 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

$ lspci -v|grep 'VGA\|modules'

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) (prog-if 00 [VG controller])
Kernel modules: i915
[...]

Xorg.0.log:

Additional Thoughts

I did have a GeForce card and the NVidia drivers were installed. It has been removed and the drivers uninstalled. The "nouveau" driver is still blacklisted for modprobe.

The kernel version is new enough that i915.preliminary_hw_support=1 boot flag should not be necessary. The i915 driver is loaded during the initial boot.

There is no support for F25 in the 01.org package repo: https://download.01.org/gfx/repos/rep...

Someone said that I should not even use the Xorg intel driver. I have created Xorg configurations to force the usage of the intel or modesetting drivers. Neither allows Xorg to start. Apart from this configuration file, the only autoloaded configuration files I can find are for input devices like keyboards and mice.

As you can see from the Xorg log, I do not have these device files:

/dev/dri/card0
/dev/fb0

What drivers am I supposed to use, and what is the recommended configuration?

Hi from your log I see that you put "nomodeset" in the grub boot line... so your workstation load without other graphics than Vesa... Try removing it, generate grub config with grub2-mkconfig -o /boot/grub2/grub.cfg (or /boot/efi/EFI/fedora/grub.cfg if UEFI). You can also try at boot to simply delete the nomodeset parameter just to see what happens (press E at grub window)

Comments

This answered the question that was asked. /dev/dri/card0 and /dev/fb0 are created after removing nomodeset from the grub boot line. Xorg now crashes while trying to initialize graphics acceleration, so I bought another NVIDIA card. Thanks for your answer anyway!
