Bug 1381014

Hi,

Thank you for filing a bug for this. So downgrading xorg-x11-server* and xorg-x11-drv* to the non updates-testing version fixes this ?

Or did you also downgrade any other packages ? There is nothing in the update which would explain this, although wait, maybe this nouveau commit:

https://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=1da8a937be19e41c51a3d516bd98cee988bca44b

Can you try downloading the 1.0.13 .src.rpm file from here:

http://koji.fedoraproject.org/koji/buildinfo?buildID=805646

And then do a "rpmbuild --rebuild ....src.rpm" on your system in a working state (so with the 1.18.4 rpms) and then upgrade to the build 1.0.13 rpm:

sudo rpm -Uvh ......x86_64.rpm

Restart X and see if that introduces the problem ? If we can pin the problem to being triggered by xorg-x11-drv-nouveau going from 1.0.12 to 1.0.13 without changing the rest of the xserver, then the commit I linked above is likely the culprit.

Regards,

Hans

Yes, it does.

I also downgraded the unpushed nss update, but I don't think it can be related.

I did that and unfortunately the problem didn't appear - videos are smooth as they should be.

Hmm, can you try installing the 1.19 packages and then use the modesetting driver? After the update do:

rpm -e xorg-x11-drivers xorg-x11-drv-nouveau

To remove nouveau (the xorg-x11-drivers pkg is a meta pkg requiring it) and then log into X again.
"xrandr --listproviders" should show "modesetting" at the end of its output now.

Talking about xrandr --listproviders, can you provide xrandr --listproviders output please ?

The issue is not reproduced when using the modesetting driver.

Hi,

Ok, so you do not have hybrid gfx in your laptop, good, and this does seem to be xf86-video-nouveau related.

xf86-video-nouveau has pretty good upstream maintenance, can you please file a bug here:

https://bugs.freedesktop.org/enter_bug.cgi?product=xorg

And pick Driver/nouveau as component ?

Important things to mention are:

1) This bug
2) That xf86-video-nouveau-1.0.13 does not show this problem with xserver-1.18.4, but does show it with xserver-1.19-rc1
3) That using the modesetting driver with xserver-1.19-rc1 makes the problem go away.

Thank you.

Regards,

Hans

Thank you very much for your help. I reported the problem upstream:

https://bugs.freedesktop.org/show_bug.cgi?id=98030

Fixed in 1.19 RC2.
