Can you grab the support logs? I wonder if you can be seeing this.

Cheers,

I can't do that because I need the one I have -> kernel 4.4.0-040400rc6-generic

otherwise the wifi won't work. I had to upgrade it from 4.3 (I think it was 4.3)

any other ideas?

I wasn't telling you to downgrade your kernel or even install a kernel,

This is the command I gave:

apt-get build-dep linux-image-3.19.0-59-generic # <-- (fix for your kernel version)

"build-dep" is to install the build-dependencies for whatever kernel you had installed.

But I see you got it working

Take a look at your kernel messages (dmesg). Perhaps you are also seeing

Code:

[10478.409066] [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x40000bf, supported mask 0x7400003f
