Video playng glitchy

[GogoAkira]

Playing netflix in chromium works flawless in GNOME.

Mate, i3, bspwm, all have the same problem in chrome netflx plays glitchy, there's lines across the screen.
i3 I installed with netinstall, just i3 and xorg, and it already had xorg intel drivers and core.

As far as I can tell kernel is using same drivers = i915 for all examples.
cpu is a Xeon E3-1200 v2/3rd Gen

I also have a GNOME laptop using a similar cpu and same 915 drivers, and I can't find a dirrence.

Only think I know is that gnome uses wayland and the rest use X .

How can I find what is causing this difference, and solve the flickering on MATE and i3 with X.

Enable the TearFree option for the Intel DDX driver: https://wiki.archlinux.org/index.php/In ... cs#Tearing

I prefer to just keep the xorg.conf in etc/x11 I find that with moving it to /etc/X11/xorg.conf.d/20-intel.conf does not work for me. This is with an sgfxi intel install not repo intstalled. T430 & X220
Using the same code.

xorg.conf

Code: Select all

 Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"

  Option "TearFree" "true"
EndSection

If you already have /etc/X11/xorg.conf then I think the fragment files are ignored. This would include the fragments shipped with packages so that may not be ideal.

an sgfxi intel install

An sgfxi Intel install of what, exactly? Debian provides the recommended modesetting driver with the X server and the Intel DDX driver is available in the repositories so relying on a few thousand buggy lines of bash to install the driver seems a bit silly.

Sgfxi will just install the Debian intel driver if you don't have it---but I don't know if it also configures the system to use it instead of modesetting with that config file.

Maybe using uxa acceleration for that vintage GPU instead of the default sna would help:

Code: Select all

  Option      "AccelMethod" "uxa"
