Acer E5-574, Intel HD 520, occasionally screen flickering

dominik232 · 2016-11-12 20:29:10

Hi.
I bought myself new laptop few days ago. I am experiencing random screen flashing. It gets black for like 0.1s. It happens when I'm doing something and it happens when I'm not either.
I've done research and here's what i found:

http://acer.custhelp.com/app/answers/de … 572-series
It says that BIOS update can resolve. I have newest version. By the way on Windows everything's fine so rather not hardware/BIOS issue.

According to ArchWiki pages
https://wiki.archlinux.org/index.php/Acer_Aspire_E5-573 (this is similar model)
https://wiki.archlinux.org/index.php/intel_graphics
I solved issues with suspend when on battery. I tried to mess with kernel parameters: i915.enable_psr=0 i915.enable_rc6=0

I tried to use both linux and linux-lts kernels, so versions 4.8.7 and 4.4.31. The same on both of them.
I tried with xf86-video-intel and without (using modesetting driver). Both the same. By the way the problem was also when I loaded Gnome with Wayland so I don't think it's xorg related issue.

By the way I extended my RAM to 16GB (2x8GB) from original 4GB (1x4GB). I readed something that this can be related, but I'm not so much into hardware to explain why (maybe the main memory is shared with GPU idk).
Laptop is usable with this issue, but it's a bit annoying. I'd be very gratefull for any help. I don't like Windows and I'd love to just remove the NTFS partition.

Are you seeing something like what is described here[1]? Spoiler: the problem is not completely fixed yet, but kernel 4.8.6 should have made it much better.

I'm not completetly sure if it's the same bug. These symptoms seems to by the same, but

* I don't have this kernel message
* I'm using another graphics adapter
* It happens randomly - doesn't matter if I'm typing this message or just running web browser with metronome for one hour.

I just tried Ubuntu 16.04 live from usb and the problem is the same there.

Also found some messages that might be related

Messages "interrupt storm" shows when screen blinks.
Just to clarify - I don't have any external screen now. I use sometimes screen connected through VGA, but this works just fine.

One more thing - I'm on kernel 4.8.7

If you don't see the same messages then it's most probably a different problem.

Just a couple comments, you say you are using a different graphics adapter but nowhere do you make mention of it or actually show anything related a different graphics adapter, the bug is about the iGPU that comes with skylake cpus, which is what you have. You should provide the full dmesg output, posting only snippets will not let people see what happens before and after and might omit other useful messages that might point to the cause of the problem.

Sory for shortcuts.
Ok, so my hardware is Acer Aspire E5-574. It has only integrated Intel HD 520. Glxinfo says it's Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2) (0x1916)

Is that without any external monitors connected? This "[drm:drm_edid_block_valid [drm]] *ERROR* EDID checksum is invalid, remainder is 140" does not look promising.

dominik232 · 2016-11-12 23:03:21

I'll Just paste from my previous answer
Just to clarify - I don't have any external screen now. I use sometimes screen connected through VGA, but this works just fine.

dominik232 · 2016-11-12 23:05:25

Maybe the problem is with the i915 module. I tried to blacklist it and force xorg using vesa, but it loads anyway. I'll try when I'll have more time.

Also there is more (it's the same dmesg, but just the latest lines)

The module is likely part of your initramfs.
What is DP-1? An actual external connector? Is there anything connected to it (loose cable) or "particles" (from the shipping stuff)?

The DP-1 is my analog external connector (VGA/D-SUB). There is nothing connected to it when those logs happens. When I connect external monitor, it works perfectly. Connected through HDMI also works flawless. And yes - when I work with some screen connected, those flickers happens only on my internal laptop screen - never on external one. And yes again - those flickers happens also without any external screen connected.

Now I work with additional HDMI monitor and xrandr outputs this

Isn't 60.05Hz mode anything to worry about?

You could try some other modes to see whether this happens there as well, but "irregular" frequencies are not uncommon.
The interesting part is however the interrupt storm on an unconnected output - if not a kernel bug, something is causing that (but I'd say they should stop when connecting a VGA output?)

These messages don't show always. I think kernel parameters i915.enable_psr=0 i915.enable_rc6=0 stops them and also flickering is less frequent (but still happens).
This is my dmesg after whole day of work

i915.enable_dc=0 i915.enable_fb=0

Does this "change" the problem (your system might freeze on condition)?
i915.reset=false i915.enable_hangcheck=false

dominik232 · 2016-11-15 16:44:13

I tried add first two (along with previous two I already had). Problem persists. Also in dmesg there is

This message isn't always there. It's random thing.
I think there's something worse than flickering. When I boot system and load desktop (Gnome or KDE) it works nice from the beginning. After 4-5 hours graphics performance is a lot worse. Seen by desktop animations, web browser scrolling, as well as glxgears - it achieves ~400FPS (instead of ~6000FPS). Didn't check if xorg restart fixes it yet.
I already used some Intel cards with Linux and I never seen such terrible support.
I tried to install Intel DRM Nightly from AUR, but it won't boot. (can't mount root fs, keyboard isn't working etc).

dominik232 · 2016-11-16 21:38:12

Ok, I did some tests and things are more clear for me now.
I solved with installing latest linux-drm-intel-nightly and now I have such message

[    3.947456] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=501 end=502) time 508 us, min 1073, max 1079, scanline start 1064, end 1099

It's more common and I found that this bug isn't solved yet. I cannot do anything with flickering, but with kernel parameters i915.enable_psr=0 and i915.enable_rc6=0 it's pretty usable, so I'll just wait for fixes. Today I used Arch whole day and apart from screen blinks it was totally stable.

Thing with losing performance is more clear for me too. FPS decrease isn't because of time of usage, but suspend. Somebody any idea with this? I already has to do some hooks before/after suspend to make it work when on battery power. Maybe I can do something to prevent graphics performance become terrible?
