[SOLVED] Segmentation fault in Xorg

Hello,
I just installed Arch on Dell XPS laptop and after executing `startx` computer hangs.

These logs may be helpful:

andrew$ lspci | grep VGA:

How can I fix it?

what's the output of

lshw -c video

and have you looked at your journal?

[ 3406.809] Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=/dev/mapper/vg0-root rw cryptdevice=/dev/sda2:luks:allow-discards quiet

Did you install the Intel microcode?

seth · 2017-10-06 07:47:17

common issue on 4.13: add "intel_iommu=off" to the kernel parameters.
Otherwise please post a complete Xorg log.

Default has been changed back to off for 4.13.5 https://git.archlinux.org/svntogit/pack … 3bcf1beba9

\o/\o/\o/

@andrzej1_1, 4.13.5 is so far only in testing. In case you intend to rather use that instead of just switching the parameter, ensure to use *all* testing repos - or you'll just face other weird problems.

After installing intel-ucode and adding intel_iommu=off, Xorg runs correctly

Thank you for help.
