Has anyone else encountered issues with the more recent 4.12 kernels on intel hardware? I've been getting some very weird behaviour over the last couple of weeks or so when coming back out of dpms powersaving mode: the framebuffer getting scrambled, rapidly panning right to left and flickering, all requiring a reboot to fix.

I've dropped back to 4.9 and so far haven't seen the issue reoccur, but it's still early days and I'm keeping an eye on it. I may also try updating xf86-video-intel to the latest git and see if that helps.

Might be a shot in the dark, but try DRI3 and/or the modesetting xorg driver (Now part of xorg-server) instead of DRI2 and xf86-video-intel.
Try something like this in /etc/X11/xorg.conf.d/intel-dri3.conf and then restart xorg.
Code:
Section "Device"
   Identifier  "FOO"
   Driver      "modesetting"
   Option      "DRI" "3"
EndSection
Feel free to change the Identifier to w/e you want.

Thanks orbea, but I don't want to switch to the modesetting driver unless I have to because it doesn't have the tear-free feature that the intel driver does, which would mean that I'd have to also start running a compositor(compton) and that brings it's own issues.

I noticed that there are some intel dri fixes coming with 4.12.10 due later this week so I'll have to wait and see if they help the situation any.

You don't have to permanently switch to test it out and see if the issue persists or not, it could help a lot in determining where the issue is or not. Though intel users might want to use modesetting by default now, it seems the intel devs support it a lot better than xf86-video-intel. Previously I seen people complain about issues that only existed with DRI2 + the intel ddx in #intel-gfx @ freenode, it took a lot of whining for the devs to care enough to fix it.

Well, after a little testing the modesetting ddx also suffers this issue, so it's looking more like a kernel regression at this point.

Is it also with both DRI3 and DRI2? You should also check dmesg for anything relevant. You could try to git bisect the kernel if you're up for that. Asking in #intel-gfx would be a good place to get help too, especially if you have some error messages or the results of a bisect.

Edit: You might be able to reproduce the issue easier with one of these xset commands.

DRI2/3 makes no odds.

For now, I think I'll take the pragmatic approach and just disable dpms in xorg.conf. Bisecting on this slow laptop would be a tortuously long process.

Well, I've tried a good 20 or so dpms off/resume cycles with 4.12.10 and so far have been unable to recreate the problem I've been having with the previous 4.12.y series kernels, so, might be premature, but looking promising.

Here's to hoping I don't have to post a "spoke too soon" later today.

Tried 4.13.0

Still seeing the occasion glitch when coming out of screen blanking, even in runlevel 3 with no Xserver running. Found this in my dmesg triggered by restoring the screen after a blank on the VC in runlevel 3:
Code:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Doesn't happen with the 4.9 branch at all.
