Description Pete Zaitcev 2016-07-25 16:53:37 UTC
Description of problem:

After a certain amount of time, the screen starts to flicker and the
laptop becomes unusable.

Version-Release number of selected component (if applicable):

kernel-4.6.3-300.fc24.x86_64

How reproducible:

100% but amount of time to trigger appears random

Steps to Reproduce:
1. Boot, log in to GNOME
2. wait
3. observe mad flicker (stand by for video)

Actual results:

Flicker, system completely unusable, except ssh

Expected results:

Working as in F23

Additional info:

Last working kernel: kernel-4.4.6-301.fc23.x86_64

This problem manifested when using upstream kernels on F23 userland.
Used kernel 4.7.0-rc5.

Workaround is to remain on Fedora 23 kernel (the userland is already
upgraded).

Video of the flicker

Note that moving the pointer keeps flicker from happening. But if the
pointer is stopped, after 1 second flicker comes back.

Still a problem with

kernel-4.6.7-300.fc24.x86_64
xorg-x11-drv-intel-2.99.917-24.20160712.fc24.x86_64

Comment 4 Afonso Bordado 2016-08-24 21:54:19 UTC
I have similar hardware (Asus UX303LN) and have encountered the same issue, a temporary fix that worked for me is to disable the panel self refresh feature.

To do this I added i915.enable_psr=0 to the kernel parameters

Comment 5 Pete Zaitcev 2016-09-05 17:07:58 UTC
See also bug #1354129 and bug #1355851. This might be another instance
of PSR being enabled by default, since the upstream kernel commit
9b58e352b463f2f096d699d47b1c4c57879b617f.

Comment 6 Pete Zaitcev 2016-10-14 16:43:05 UTC
Fixed in kernel-4.7.5-200.fc24.

Comment 7 Pete Zaitcev 2016-10-14 16:44:22 UTC
Ouch, it might be the grubby finally took i915.enable_psr=0, so maybe
not fixed. But whatever.
