Red Hat Bugzilla – Bug 1541030
Current xorg-x11-drv-intel driver in EL is outdated and does not support Intel Kabylake GT2 GPU from Intel Core i7-7700HQ
Last modified: 2018-04-10 07:54:07 EDT
Created attachment 1389544 [details] SRPM file Intel Kabylake GT2 GPU from Intel Core i7-7700HQ CPU isn't supported by current X.Org X11 Intel video driver in EL7 ("xorg-x11-drv-intel-2.99.917-26.20160929.el7.x86_64.rpm"): "(EE) No devices detected". This GPU works ok with "modesetting" driver, but modesetting isn't a complete replacement for the intel driver: "modesetting isn't a complete replacement for the intel driver. 2D performance, virtualisation, colour management and other vendor-specific features aren't supported with xorg-x11-drv-modesetting" https://bugzilla.redhat.com/show_bug.cgi?id=1445583#c14 I already backported xorg-x11-drv-intel package from Fedora 28 ("xorg-x11-drv-intel-2.99.917-32.20171025.fc28.x86_64.rpm"): https://koji.fedoraproject.org/koji/buildinfo?buildID=996252 Here is my COPR repo with packages for EL7 ("xorg-x11-drv-intel-2.99.917-34.20171025.el7.x86_64.rpm"): https://copr.fedorainfracloud.org/coprs/scx/xorg-x11-drv-intel/ My RPM SPEC: http://wklej.org/hash/6a3bc069cd2/txt/ Installation Instructions: cd '/etc/yum.repos.d/' curl 'https://copr.fedorainfracloud.org/coprs/scx/xorg-x11-drv-intel/repo/epel-7/scx-xorg-x11-drv-intel-epel-7.repo' > 'scx-xorg-x11-drv-intel-epel-7.repo' yum install 'xorg-x11-drv-intel' TL;DR Please upgrade X.Org X11 Intel driver in EL 7.5 from 20160929 to at least 20171025. Thanks in advance.

I'd be fine with updating this. The intel driver's change rate has dropped significantly, making me more willing to trust an arbitrary snapshot.
It seems that dropping the "0001-sna-Let-modestting-glamor-handle-gen9.patch" solves the problem. However, due lack of time, I can't say too much about the long-term stability of this solution. The 20171025 driver was already tested in Fedora >= 27 since October 2017. Please remember that even after 2.99.917-27, intel driver is still disabled by default, because the xserver now defaults to the modesetting driver for all recent GPUs. SPEC file from "xorg-x11-drv-intel-2.99.917-31.20160929.el7.src.rpm": http://wklej.org/hash/441ad00949e/txt/ Summary: I backported changes from "xorg-x11-drv-intel-2.99.917-34.20171025.el7.src.rpm" to the 20160929 driver and it seems to work, but I can't say too much about the long-term stability of this solution.
