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).

Still a problem with kernel-4.6.7-300.fc24.x86_64 xorg-x11-drv-intel-2.99.917-24.20160712.fc24.x86_64
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
See also bug #1354129 and bug #1355851. This might be another instance of PSR being enabled by default, since the upstream kernel commit 9b58e352b463f2f096d699d47b1c4c57879b617f.
Fixed in kernel-4.7.5-200.fc24.
Ouch, it might be the grubby finally took i915.enable_psr=0, so maybe not fixed. But whatever.
