As the subject line says when I installed 1.18.2 from koji my Lenovo T450 freezes frequently that lasts aboout 20-30 seconds and starts again. Total freeze of mouse/keyboard/screen. I have Intel HD graphics. I am using the KDE plasma desktop. The Xorg.0.log file shows: [ 1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some input events have been lost. [ 11[ 1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some input events have been lost.

I kept testing this. It is much more stable with 1.18.1-3 but it did happen once when I pushed the cursor off the screen. But it happens very rarely with this version of xorg. I am using libinput-1.2.1-3 the version libinput-1.2.1-4 introduced some Thinkpad T450 fixes but this does not change anything. This could also be a KDE issue that is somehow triggered more with 1.18.2. If this is not happening on GNOME one should let Rex Dieter know as well. On KDE I am using rendering backend OpenGL 3.1 and glx interface.
Setting interface to EGL avoids the problem with 1.18.1. I will try with 1.18.2. My old setting was EGL but yesterday I changed the interface to glx.
Final analysis: xorg-x11-server-1.18.1-3, EGL interface, libinput-1.2.1-3 or -4 NO PROBLEMS xorg-x11-server-1.18.1-3, glx interface, libinput-1.2.1-3 or -4 OCCASIONAL FREEZE xorg-x11-server-1.18.2-1, either EGL or glx interface, FREQUENT FREEZE
This bug seems related although different messages but same symptom. https://bugs.freedesktop.org/show_bug.cgi?id=94515
This problem still persists with xorg-x11-server-11.8.2-2 as well. It happens with intel graphics only because it is working fine on my nvidia machines. The other observations is that many people who reported this seem to be using KDE plasma. It would be intersting to find out if it happens under gnome as well.
I experienced similar frequent hangs of maybe 15-20sec with a Lenovo ThinkPad X1 Carbon. Downgrading to xorg-x11-server-Xorg-1.18.1-3.fc23.x86_64 did the trick, it seems.
The report https://bugs.archlinux.org/task/48549 tested a patch that seems to work. I used the patch to rebuild the Fedora 23 xorg-x11-xserver-1.81.2 rpm and indeed the problem ius gone. I will attach the patch as well.
Created attachment 1138041 [details] Patch for freeze issues
thanks - hopefully we can have a SCRATCH-BUILD and get that offending packages out of "updates-testing" ASAP and only when it's confirmed as fixed a new updates-testing build all day long use "dnf --exclude=xorg\*" to not get your system ruined as regular updates-testing user is annoying
I heard speculation this patch could also address bug #1317145 I'll see if I can find some time to confirm that soon.
Without the proposed patch, my problems were fixed by https://bugs.freedesktop.org/show_bug.cgi?id=94685, we need a new xorg-x11-drv-intel build.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. 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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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. Thank you for reporting this bug and we are sorry it could not be fixed.
