Description

I experience this bug too. When continuing to wayland session, it is still there (so not only when logging in). The flickering disappears when the cursor gets hidden or after VT switch, so probably drm related. The bug is present on all kernels in repositories, but with nightly-build 4.1.0 drm-intel kernel the flickering is gone. Components: F22 Lenovo T520 i915, Intel Corporation 2nd Generation Core Processor Integrated Graphics Marek, any chance you can bisect which commit fixes this and then maybe jwb could pull it in for release? (In reply to Ray Strode [halfline] from comment #2) > Marek, any chance you can bisect which commit fixes this and then maybe jwb > could pull it in for release? So far I got to merge commit 14aa024, which is merge of this branch: http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next-merged Some commit(s) in this merge fix the issue. Unfortunately, I won't have time to look into it at least till Monday, maybe Wednesday. Looks like this may be a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1200581 I have a laptop which exhibits this behaviour, so as I just told Ray I can bring it to the Westford office if we have trouble identifying the fix and need a machine for testing. *** Bug 1200581 has been marked as a duplicate of this bug. *** Proposed as a Freeze Exception for 22-final by Fedora user rstrode using the blocker tracking app because: flickering for a large number of users will give a bad "out of the box" experience. it's clearly not a blocker, but we've narrowed where the problem is down a series of commits. if we can isolate it to a commit or two, jwb said he's willing to add the commits to the kernel for release. Discussed at the 2015-05-14 blocker review meeting.[1] Voted as AcceptedFreezeException - this is a bad bug on affected hardware and would affect first boot after install from live image, would be good to get a sufficiently targeted fix in the next few days [1] http://meetbot.fedoraproject.org/fedora-blocker-review/2015-05-14 As a point of information, the system I have exhibiting this issue has Intel Ironlake Mobile GPU. Put up a video of the flickering here, as it happens both under GDM and under Wayland. What I noticed is that it is related to the mouse pointer as the flickering only happens on the part of the screen that is below the mouse pointer at any given time: https://plus.google.com/photos/109262178267841117787/albums/6149135938534130433/6149135938136021458 You should also have a look at https://bugzilla.redhat.com/show_bug.cgi?id=1199890 which is a duplicate imho. You can find more info there. My Lenovo ThinkPad x220 is also affected by flickering on login screen DMI: LENOVO 4287CTO/4287CTO, BIOS 8DET58WW (1.28 ) 02/14/2012 Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz (fam: 06, model: 2a, stepping: 07) VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:02.0 0300: 8086:0126 (rev 09) Two other possible duplicates: https://bugzilla.redhat.com/show_bug.cgi?id=1216970 https://bugzilla.redhat.com/show_bug.cgi?id=1214468 Created attachment 1026784 [details] patch that didn't work So based on comment 12, i tried the above patch against 4.0.3-301 It didn't resolve the problem on sgallagh's laptop that i have here. I'm not entirely certain sgallagh's laptop is showing the same issue Marek is seeing though, because for him the problem is resolved with airled's drm-next-merged branch, but on this laptop the problem needs some fix after that from the drm-intel-next branch. will do more testing but have to go right now. (looking at the patch now it makes sense it wouldn't work, since it's not actually doing anything to prevent the cursor for being disabled, i guess fedora is shipping code from a before a different flickering bug was introduced that comment 12 addresses) I used to see some flickering on my login screen in Rawhide, but after update at Saturday, it went away. Note that I did not updated kernel, I am still using 4.0.0-1.fc23. issue seems fixed by a patch on the upstream bug ( https://bugs.freedesktop.org/show_bug.cgi?id=90508 ) (In reply to Ray Strode [halfline] from comment #17) > issue seems fixed by a patch on the upstream bug ( > https://bugs.freedesktop.org/show_bug.cgi?id=90508 ) When is this expected in the repos? I just updated my Asus U64E BAL5 to the latest software and I'm still seeing a flicker in GDM and in GNOME on Wayland. It's not as bad as it was - GDM is usable now - but it's still there. Current packages are xorg-x11-drv-intel.x86_64 2.99.917-6.20150211.fc22 @System gnome-session-wayland-session.x86_64 3.16.0-1.fc22 @System xorg-x11-server-Xwayland.x86_64 1.17.1-12.fc22 @System kernel-modules.x86_64 4.0.4-300.fc22 @System I've added the patch Anders sent upstream that Ray tested to the F22 and F21 kernels. It will be in the next build. kernel-4.0.4-301.fc22 has been submitted as an update for Fedora 22. https://admin.fedoraproject.org/updates/kernel-4.0.4-301.fc22 kernel-4.0.4-201.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/kernel-4.0.4-201.fc21 Package kernel-4.0.4-301.fc22: * should fix your issue, * was pushed to the Fedora 22 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing kernel-4.0.4-301.fc22' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2015-8690/kernel-4.0.4-301.fc22 then log in and leave karma (feedback). kernel-4.0.4-301.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report. No probs, no flickering on login! Works now on my Asus U64E BAL5 - in fact, I'm now running GNOME Shell on Wayland. The patch seems to be missing in f20 version of 4.0.4 kernel? (In reply to Ozkan Sezer from comment #26) > The patch seems to be missing in f20 version of 4.0.4 kernel? Added now. Thanks for pointing this out. kernel-4.0.4-201.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report. kernel-4.0.4-101.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/kernel-4.0.4-101.fc20 |
