There are *some* issues with intel gpu's and recent kernels. I can't use multiple monitors in most of the cases as the i915 module misinterpret possible resolutions, for example. https://bbs.archlinux.org/viewtopic.php?id=246230 https://bugzilla.redhat.com/show_bug.cgi?id=1570392 https://intel-gfx-ci.01.org/cibuglog/open_bugs.html I'm stuck on aur/linux-lts49 on my Zotac CI547 in the meanwhile as everything works there. But better than nothing - or 1024x768 ;)
