I have a Lenovo Thinkpad L460 with Intel graphics. Output of
lspci | grep VGA
is
00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 07)
I have installed xf86-video-intel. The output of
xrandr
is
Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767
eDP1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 309mm x 174mm

HDMI2 disconnected (normal left inverted right x axis y axis)

If I turn the VGA output, which is listed as "DP2", off, and then back on, e.g., via
xrandr --output DP2 --mode 1920x1080
X freezes and I can't do anything, not even escape to another tty, so I have to manually power off my computer. The same thing if I start with VGA disconnected, and then connect it. The same thing happens with DP output and HDMI output.
My Xorg.0.log can be found here: http://pastebin.com/fHW34BrK. Nothing else was written to it after I executed the above command to turn on VGA; the VGA display will work for a second, and then X will freeze, but no error message will be reported to the log file. I have tried the various fixes listed here: https://wiki.archlinux.org/index.php/intel_graphics, under "X freeze/crash with intel driver" and "Skylake Support", and none of them work.
EDIT: A new piece of information: I went to BIOS and went to the "Display" section and set it so that my laptop uses VGA output on boot, rather than my laptop screen. Now, everything works fine if my monitor is connected at boot time. However, if my monitor is not connected at boot time, but connected later, then I have the same problem: switching it on freezes the computer.

Hello,
I'm getting the exact same issue on an HP EliteBook G3 850.
Same crappy GC :
00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 07)
I've tried the same steps as you, with no more luck.
Which information shall I provide to help finding out where this issue come from ?
uname -r
4.5.4-1-ARCH
Thanks.

Hi,
first of all: I am in the same boat. I also have a Thinkpad L460 and the Intel graphics under Linux is total crap. I am also getting freezes and lockups with external monitors (especially with the Lenovo Ultra Dock).
There is one thing I have noticed though: With Kernel 4.6 everything has become a bit better. So give it a try (4.6. is in testing right now).
@lighthearted: Just a hint for you: Update your L460 BIOS. It has newer Skylake microcode so you don't need the "initrd=\intel_ucode" thing any more

Hi,
Thanks direx, I confirm that the kernel 4.6.0-1-ARCH fix that issue.

Updating BIOS/UEFI firmware is mostly a good idea, removing the intel_ucode part is not .
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

I've had this issue when using a kernel <4.6
At the moment, using "linux-mainline" from AUR and booting without the "intel_pstate=no_hwp" kernel parameter ( needed for kernel <4.6) solves this issue completely.
This is until kernel 4.6.1 gets passed Testing.

Caveat: booting with "linux-mainline" breaks virtualbox.
Virtualbox's dkms driver builder can't build against 4.6.0, I haven't worked out why.

I have the same issue with the kernel:
4.17.5-1-ARCH
I'm using a MSI Apache Pro GE72 6QD laptop. I have an external monitor connected to HDMI port. xrandr output:

While I'm willing to believe you to have similar symptoms it has been 2 years and a lot of the landscape has changed thus you are unlikely to have the same cause, please make your own thread about this.
