[SOLVED]IntelHD 5500 Screen flickering

I tried:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "SNA"
EndSection

i also tried to add
i915.enable_rc6=0
and also i915.enable_psr=0
as boot parameters but none of the above helped.

now my head hurts because i spent all the time on the heavy flickering screen. it's a fresh arch install running gnome, the notebook is an acer e5-772 and i am open for suggestions. uninstalling the intel driver did not help.
i wonder is there maybe another intel driver flying around in the AUR which could help? i just removed windows and don't wanna go back so anything helpful is welcomed very much.

Re: [SOLVED]IntelHD 5500 Screen flickering

Gnome does not use Xorg by default, it uses Wayland.  Wayland does not use that configuration file.

Look around the forums for using Xorg on Gnome.

@ewaller

thanks for that suggestion. sadly, also under xorg/gnome, the screen flickers all the time, plus, the touchpad is very difficult to operate as it has the tendency to jump back to the center of the screen.

Re: [SOLVED]IntelHD 5500 Screen flickering

There have been some reports about screen flickering with intel graphics, it can be a problem with the kernel driver and not with something higher on the stack. You should check the output of dmesg for any messages with "CPU pipe A FIFO underrun", "Atomic update failure on pipe A" or something along those lines.

If you see messages like the ones I have pointed out, search for similar problems here[1] and open a new bug report. Your problem may look similar to someone else's but it might not be.

Re: [SOLVED]IntelHD 5500 Screen flickering

You can try linux 4.9.2 from testing. In the ChangeLog there is

commit 18a00ac6d7f106901356e1fa9c082730a2318ed5
Author: Paulo Zanoni <paulo.r.zanoni@intel.com>
Date:   Wed Dec 14 12:55:37 2016 -0200

    drm/i915: skip the first 4k of stolen memory on everything >= gen8
    
    commit 6ba0566cf2afcdb17bff882e3a95cbbcb22c4a83 upstream.
    
    BSpec got updated and this workaround is now listed as standard
    required programming for all subsequent projects. This is confirmed to
    fix Skylake screen flickering issues (probably caused by the fact that
    we initialized a ring in the first page of stolen, but I didn't 100%
    confirm this theory).
    
    v2: this is the patch that fixes the screen flickering, document it.

@andreyv

that looked like a nice solution. but it did not work here sad i will forever regret the day when i bought that notebook with the idea of giving intel another chance. never again! i will continue with AMD in the future.

Edit: i don't know if this is any helpful but whenever i move the mouse poiinter the flickering stops.

Re: [SOLVED]IntelHD 5500 Screen flickering

I solved the problem with the famous try+error principle.

/etc/X11/xorg.conf.d/20-intel.conf
looks like:

Section "Device"
        Identifier "Intel Graphics"
        Driver     "intel"
        Option     "AccelMethod" "uxa"
        Option     "DRI" "2"
EndSection

and as kernel i have installed linux 4.4.42-1.

that's it!

sorry for the double account i did not know it existed.

Re: [SOLVED]IntelHD 5500 Screen flickering

uxa is slow, you could try getting rid of xf86-video-intel and it's config files althougether and use Xorg's built in modesetting driver. Intel has practically abandoned the ddx driver and distro's are starting to drop it (Debian and soon also Fedora)

@ugjka

Thank you for that suggestion. I removed xf86-video-intel and renamed 20-intel.conf to 20-intel.back.
Everything still works. smile
