I am using debian. I recently have purged X11 and xcfe4 and reinstalled them both but whenever I lauch Xorg --configure I get this:

(++) Using config file: "/root/xorg.conf.new" (==) Using system config directory "/usr/share/X11/xorg.conf.d" modprobe: FATAL: Module fbcon not found in directory /lib/modules/$kernel intel: waited 2020 ms for i915.ko driver to load Number of created screens does not match number of detected devices. Configuration failed. (EE) Server terminated with error (2). Closing log file.

Maybe the issue is with the content of xorg.conf.new? A snippet of the file:

Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection

  • First thing to do is also to upgrade your kernel, as the newer X drivers may need newer kernel modules. If you have a custom kernel, you may need to enable some modules. Commented Oct 31, 2018 at 10:16
  • I already have the latest kernel. Commented Oct 31, 2018 at 15:14

Just by random, I ran into this problem just this hour with exact same output.

I myself disabled modeset with kernel command line "[...] nomodeset i915.modeset=0"

As https://askubuntu.com/a/137482 and even more https://askubuntu.com/a/193417 suggest, modeset is recommended.

When I reenabled modeset, driver was running fine.

P. S.: Today you typically don't configure the monitors with xorg.conf but use randr extension (so "xrandr" or "arandr" commands or your display managers configuration tool). See https://wiki.archlinux.org/index.php/Xorg#Monitor_settings and https://wiki.archlinux.org/index.php/Multihead

    I never disabled modeset, as a matter of fact I don't have i915.modeset=0 in /etc/default/grub. I also tried to add i915 and intel_agp drivers in /etc/initramfs-tools/modules but it didn't work either. Commented Oct 31, 2018 at 15:37
