(Another) Flickering Screen

Jijou · 2018-02-05 19:37:15

Hi everyone, I've had this flickering problem on my screen since my fresh Arch install, 2 months ago.

Description
When not moving the mouse for about 2 seconds, the screen darkens a bit, enough to be disturbing, to me.
When I mouve the mouse the brightness gets back to initial.

If the mouse cursor happens to be blicking (e.g. when on a search bar, or editing this very post), the flickering pattern follows the cursor's one : it flickers at each cursor appearance/disappearance.

Hardware
The computer is a HP EliteBook 820 (1st Gen)
Processor is Intel I5 4300U with Intel Graphics 4400

lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

What I tried to do

set both enable_rc6=0 and enable_psr=0 in the /etc/modprobe.d/i915.conf And in the kernel boot parameter options
removing "xf86-video-intel" and the .conf file in /etc/X11/xorg.conf.d/ (By the way How can I know that Xorg uses the modesetting driver? since the i915 ERRORS are still displayed by dmesg)

A clue?
When I play a video under VLC, The flickering doesn't happen, would it be possible to use the same "disabling power saving" option as VLC?

Thank you very much for having a look at my problem.

It will be in your Xorg log as long as you don't 'grep' away everything that's relevant. Although in this case, even the grepped output showed that the x11 intel driver was not in use, so presumably modesetting was loaded.

As for i915, that is the kernel driver, it has nothing at all to do with X11 xf86-video-intel driver.

Same symptoms here https://bugs.archlinux.org/task/57354 please note reporting upstream bugs especially kernel bugs on the arch bug tracker will just result in the bugs assignment with no further action being taken.

Thank you for your answers.

I now know you are right, a # less /var/log/Xorg.0.log command let's me see indeed that Xorg loads the "modesetting" module after failing for the "intel" one.

But then I was able to solve a tearing issue using the intel configuration file (by adding Option "TearFree" "true"). So how does it come that my /etc/X11/xorg.conf.d/20-intel.conf is taken into account when the corresponding intel module is not?

Also, do you think that my intel module loading problem comes directly from the kernel problem (revealed by the 2 drm error message)? I see hope in trying to solve this module loading problem first (I probably shouldn't).

I am a bit scared to go further in that direction. For the time being It would be too much of Do It Myself. (I begin to accept the idea though)

Thanks again

Names of xorg.conf files are meaninless except for defining parsing order. You could just as well name that file 20-chewbaca.conf and it would still be parsed. Now most of the content that you'd find in examples for 20-intel.conf might only be relevant when the xf86-video-intel driver was in use, but the file would still be parsed.

There's an intel module loading problem? Which one? You mean in the Xorg log? That's not a problem - that's expected if you have uninstalled the xf86-video-intel package.

Even when I reinstalled the xf86-video-intel package, Xorg failed to load the intel module.

Is that the latest Xorg.log? The dated kernel version and the missing intel X driver makes me wonder.

Please post the output of `lspci | grep 3D`.

Yes it is.

And that may be weird because:

#uname - r

4.14.15-1-ARCH

When #cat /var/log/Xorg.0.log | grep "Current Operating"

How can Xorg not be aware of (or not using?) the new kernel version. It has to use it right? Because the old one is changed/not here anymore. Maybe no Xorg modification has been made since the 4.14.8-1-ARCH one? What do you think?

I get no result for that. what are you thinking about?

Again, Thanks for you answers. Feel good to be helped

Just confirming that this wasn't a hybrid graphics system.

Currently logs are not generally under /var/log, you should find them under ~/.local/share/xorg/
