Description of problem: The package xorg-x11-drv-intel is heavily outdated, according to the RPM version it is based on a git snapshot almost a year old. I currently experience crashes when using Libreoffice with SNA enabled, which most likely have been fixed upstream a while ago. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.99.917-28.20160929.fc26.x86_64 Although on newer hardware modesetting+glamor is a viable alternative to asic specific 2d drivers, this approach does not work well on older hardware (<= gen5). On my Core-i5-640M powered Elitebook, glamor is noticable slower than SNA - especially when using "heavy" applications such as libreoffice or eclipse.
Worse, even Fedora-27 ships with the same outdated intel package from 20160929 - almost one and a half year old when fedora 27 will be released.
Please read : https://bugzilla.redhat.com/show_bug.cgi?id=1413251 Since F26 xorg-x11-server defaults to use modeset driver instead of intel.
1. As mentioned in the initial report, modeset is using opengl for 2d accaleration (glamor) - which does not work that well for older intel chipsets (gen4, gen5). 2. Furthermore, gen2 (i845) and the still quite common gen3 (i915, i945) are still using xorg-x11-drv-intel, because glamor requires pixel shaders which gen2 does not support at all and gen3 not in a glsl compliant way.
Hm, Intel's 2017Q2 driver stack released on July 18 still seems to come with xf86-video-intel version 2.99.917. That is, the same version that is already packaged in Fedora. See https://01.org/linuxgraphics/downloads/2017q2-intel-graphics-stack-recipe

I have one Ironlake (gen5), I'm trying understand why after 2 or 3 days or one week of work and using suspend 2 or 3 times per day , my laptop have huge slowdowns [1] some processes use more that 100% of CPU and gets very hot, my latest tests says that modeset works better but not for sure ..., so I may try this update on F26 , thanks for yours explanations .

I built the same xorg-x11-drv-intel-2.99.917-31.20171025 src.rpm for F26 [1] and after 4 months I can say that it works much better, I almost forget the problems with graphics , So please update xorg-x11-drv-intel from 2.99.917-28.20160929.fc26 to xorg-x11-drv-intel-2.99.917-31.20171025.fc26 Thanks.

This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
