[SOLVED] "No screens found" since kernel 3.17, Intel HD 4400

nils_z · 2014-11-06 13:49:42

Hi,

my X server doesn't start anymore after updating to kernel 3.17.
Error: (EE) No devices detected.

If I downgrade the kernel back to 3.16 with

pacman -U /var/cache/pacman/pkg/linux-3.16.4-1-x86_64.pkg.tar.xz

everything works fine. When upgrading to linux-3.17 again, I can't start X anymore. All other packages are up to date.
I use a Lenovo T440s with Intel HD 4400 graphics, xf86-video-intel is installed.

I looked at the logs and googled a lot but couldn't find a solution so I hope anyone else can help me.

I start X via startx. Some logs and files which could be useful for resolving the problem:

~/.xinitrc:

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

numlockx &
setxkbmap -option terminate:ctrl_alt_bksp de

exec dbus-launch --exit-with-session i3

Do you have an /etc/X11/xorg.conf or any other config files? If so, what's in them? Have you tried without xorg.conf to see what happens?

nils_z · 2014-11-07 09:55:11

I don't have a /etc/X11/xorg.conf. I created an empty one with Xorg :0 -configure, but this didn't change anything, so I removed it again. In /etc/X11/xorg.conf.d/ I only had a file for my trackpoint, but removing it didn't have any effect on the problem, too. There was a message that X is also reading config files from /usr/share/X11/xorg.conf.d/, but temporarily removing this folder also didn't help.

After the X server closes with errors, xinit says:

xinit: giving up
xinit: unable to connect to X server: Connection refused

Is there any command to check if the GPU is blocked by something?

Could this be related to the intel microcode updates? In 3.17-2 intel's processor microcode isn't updated automatically anymore and you have to modify some bootloader config.

Have you done this?
https://wiki.archlinux.org/index.php/Mi … de_Updates

nils_z · 2014-11-08 12:21:48

Thank you for the hint. I have read about the changes to the microcode update system and hadn't applied them yet because according to the check on the wiki page there is no microcode update available for my cpu.
I could solve my problem now, it was not related to the microcode update, but this led me to the real cause.

I have a setup with full disk encryption with cryptsetup, so I have a separate boot partition containing the initramfs image. When updating the kernel, my system placed the new initramfs image in the folder /boot, not in the boot partition where it belongs. The microcode file was also placed wrong, this led me to the problem when I was looking for it. So I had installed the new 3.17 kernel and was booting with the old 3.16 initramfs image, this screwed my system up.

Moving the new files initramfs-linux-fallback.img, initramfs-linux.img, intel-ucode.img and vmlinuz-linux from the /boot folder to the boot partition solved it.
Seems like I configured something wrong when installing arch. The installation and cryptsetup manuals were a little bit confusing concerning this boot partition, I think my boot partition should be mounted to /boot and the current content of this folder is not needed (renaming the files had no effect). I'll see how I can fix that.

Thank you very much for your help!

In case anyone has the same problem, this is what I did to correct my wrong boot partition/folder layout as described in my last post:

Only do this if you are really sure that you have the same incorrect /boot folder and boot partition layout I had. Doing this on a correctly configured system will make it unbootable!

Backup everything in folder /boot
Delete everything in folder /boot (I only had an empty EFI folder, vmlinuz-linux and the files created by mkinitcpio there)
Make sure that system boots normal. If not, restore backup. Don't perform the next step!
Add boot partition to fstab, so that it is mounted to /boot

My fstab entry:

UUID=XXXX-XXXX	/boot	vfat	defaults	0	2

Determine UUID of boot partition with

lsblk -o name,uuid,mountpoint

Now mkinitcpio creates its files in the right place, so future kernel or microcode updates should work without problems.
