Title: About xserver-xorg-video-intel problems and non-free.
Package: xserver-xorg-video-intel
Version: 2:2.99.917+git20161206-1 amd64
Dear maintainers,
WHEN?
X.org with modern Intel iGPU,
video motion qualities are bad,
without firmware-misc-nonfree package.
Using firmware-misc-nonfree solves the problem,
so this is a limited, minor situation,
like one does not use non-free packages
but uses modern Intel iGPU such as Intel HD Graphics.
WHY?
If you install Debian stretch for modern Intel CPU
machine using iGPU, and without non-free,
xserver-xorg-video-intel would be installed,
then it cause the video quality problem.
WHAT SHOULD BE DONE?
Uninstalling xserver-xorg-video-intel and
installing firmware-misc-nonfree seems best.
The problem is, it depends on a non-free package.
In case someone wants to obtain better X graphics
by Intel iGPU, without using non-free packages,
please consider that xserver-xorg-video-intel packge
has an optional SNA and TearFree setting file,
something like below.
/usr/share/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
I know the package is not recommended since 2007,
so the setting above should be a option, not default
(commented out, for example.)
INFORMATION
Situation like this was told in the bug reports
#735322 in 2014, #789271 in 2015, #893446 in 2018.
#781666 said the TearFree does not work in Jessie.
In #735322 thread, they said SNA will be enabled
by default in the future.
I use Intel 7th gen Core i3-7320 and its iGPU
with MSI B250M MOTOR motherboard,
connected to my TV via AV amp by HDMI cables.
I disabled Hyper-theading and virtualizations on BIOS.
No special GRUB settings including kernel options.
Here is a summary.
A = use non-free, install firmware-linux-nonfree.
B = do not use non-free, use 20-intel.conf above.
C = do not use non-free, no 20-intel.conf above.
A: Everything is going okay.
B: Almost okay, except DMC firmware failure log at boot.
C: X video quality is bad, and DMC firmware failure log.
Suspends to RAM and resumes are no problem in all the cases.
B improves videos both in windows and fullscreen mode,
but may corrupt older Intel CPU systems, such as #781666.
By the way, I,
1. Installed Debian 9.4, got caught in C.
2. Manually fixed by 20-intel.conf, B.
3. Upgraded to Debian 9.6.
4. Found firmware-misc-nonfree when I dig DMC log.
5. Installed firmware-misc-nonfree, removed 20-intel.conf.
6. Uninstalled xserver-xorg-video-intel.
Related package versions:
I'm using Debian Stretch, 9.6, with contrib and non-free.
