TTY freeze on lid close

The problem starts when the Lid on the laptop is closed, what happens is that the screen fails to update and logs do not even get written. It is like some kind of hard crash that doesn't kernel panic.

I have no login display manager and boot straight to a virtual tty and work from here / run startx.

The output of

/etc/systemd/logind.conf

is:

As far as I can tell I have no udev rule and acpid will not fire off handle.sh when the lid is shut (as far as I can tell).

As a side note `systemctl suspend` sleeps the machine fine and it also wakes up no problem with keyboard input.

Re: TTY freeze on lid close

SysReq? SSH in?

Not a Sysadmin issue, moving to NC...

Re: TTY freeze on lid close

Sorry for the wrong sub-forum.

SysReq does not respond, neither does SSH.

The machine pretty much stops responding altogether (no keyboard, sound loops if was playing at the time, display freezes tty and x, no mouse, no usb).
For example, if I was running

watch -n 1 date

the date would stop incrementing after the lid is closed and then opened.

Re: TTY freeze on lid close

Have you tried playing with other kernels? LTS, for example?

Re: TTY freeze on lid close

So I have just tried `Mainline` and had no luck, but just switched to LTS and found out that the issue isn't present. However with LTS my graphic drivers do not work and I am unable to start x.

I have a theory as the machine that I am using is Intel Skylake and I believe that LTS does not support that IIRC.

Re: TTY freeze on lid close

Actually, just read the wiki and added

i915.preliminary_hw_support=1

to my kernel parameters and the problem has seems to have gone away, not sure how to proceed with fixing this on 4.4?

Re: TTY freeze on lid close

I have managed to get this working on the 4.4 Kernel by adding `intel_pstate=no_hwp` to my kernel options.
