RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

Comment 5 Adam Jackson 2018-02-01 17:33:58 UTC 
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.
Comment 6 Tomasz Tomasik 2018-02-01 23:40:07 UTC 
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.

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.

We have already done this in 7.5, so that's good to hear.
