[Bug 1819968] Re: Colour banding in Lenovo G50-80 laptop display (i915)

2019-12-03 Thread Ubuntu Kernel Bot 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
disco' to 'verification-done-disco'. If the problem still exists, change
the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Hi,
I keep trying all kinds of solutions found on the web to fix this but the 
banding stays on for me? Am I doing something wrong? Is there a method to 
manually specify the BPP?

upstream, I am hoping that you'll do it for the Lenovo G50 models, like
you did it e.g. for the HP Pavilion a few months ago :-)

How about sending the patch yourself? It can be fun ;)

2019-03-14 Thread Kostas Papadopoulos 
Thank you for your quick response!

This regression / bug was found out almost 2 YEARS ago:
https://bbs.archlinux.org/viewtopic.php?id=225215
and a patch was sent to upstream (see post #2), but apparently it was never 
pulled.

Regarding hex vs dec, the file in master they seem to be mixing both:
https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/drm_edid.c

The product id number for a specific panel is found in Xorg.log:
fgrep EDID /var/log/Xorg.0.log
[   751.496] (II) modeset(0): EDID vendor "SDC", prod id 18514

Anyway, I am hoping that Ubuntu, which has the biggest base of desktop
Linux users (and in particular of people who may have bought laptops
without pre-installed Windows, like Lenovo G50-80 and G50-70), would
choose to fix this regression for Ubuntu users.

** Description changed:

  Colour bandind is visible everywhere in the system. I believe it's not a
  hardware problem, since booting with 'nomodeset' works as expected and
  the previously installed Ubuntu 14.04 also worked.
  
  I tried installing kernel 4.18.0-16.17 from ppa:canonical-kernel-
  team/ppa but the problem remained.
  
  There were already similar bugs, https://bugs.launchpad.net/bugs/1749420
  , https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794387 and
  https://bugs.launchpad.net/bugs/1788308, but the fixes provided for
  those bugs did not work for my specific monitor.

[Bug 1819968] Re: Colour banding in Lenovo G50-80 laptop display (i915)

Since the introduction of kernel 4.8 I've been experiencing color 
banding on my Lenovo G50-80 notebook. I also had reports of the same 
symptoms on the G50-70 model.

I figured out that the problem had been introduced by commit 
210a021dab639694600450c14b877bf3e3240adc

The G50-80's LCD panel supports 6bpc, but is now set to 8bpc,
and the system probably falls back to 6bpc
without any dithering, which result in heavily banded gradients.

I fixed it for myself by adding an EDID quirk for that particular LCD 
panel (see the attached patch). It's unknown to me, however, if there 
are any other panels affected by the issue, so maybe a more general
solution might be desirable.
