Created attachment 121027 [details] output of the lspci -vvv to differentiate from the bug #91393 I'm creating a new one. It because I have different symptoms and end solutions offered there do not help. Here is a video to demonstrate the problem https://www.youtube.com/watch?v=DZIR4qnfOH8 With the stock ubuntu 15.10 kernel version 4.2 this problem persists and there's no way to get rid of it. With the current drm-intel-nightly kernel: $ uname -a Linux chrome 4.4.0-994-generic #201601112101 SMP Tue Jan 12 02:02:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux the problem occurs only after a new boot. Then I need (almost blindly) login into my system and start 'xset dpms force off' command once or several times and then the flickering is gone even after I resume from the sleep. $ sudo lshw -c video *-display description: VGA compatible controller product: Broadwell-U Integrated Graphics vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 08 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:43 memory:e0000000-e0ffffff memory:d0000000-dfffffff ioport:1800(size=64)

We seem to have neglected this bug completely. Apologies. Is this still an issue with latest kernels?
oh, you mean that the bug could simply disappear with a newer kernel version, huh? So, what newer kernel version do you mean exactly?

I've tested with teh 4.9 kernel and it seems like the problem is fixed with it
