dmesg
I'll have to recompile that kernel, but here are already the dmesg results with
4.15.12 with drm.debug=0x1e for now.
I actually didn't need to use ssh because even if Xorg looks frozen,
ctrl-alt-f2 works (it just takes some time to take effect. Apparently moving
the mouse helps)
<span class="quote">> You mentioned vga before, is that correct? Don't you mean DP?</span >
Well, it's really a VGA plug that I have on this laptop, even if in xrandr it
happens to be called DP-2.
<span class="quote">> do this worked with a previous version of mesa?</span >
As far as I can remember, I have never been able to get a stable Xorg workspace
without disabling acceleration, before adding intel_iommu=igfx_off.</pre>
