Update: 1.4 with Mesa 19.1.3 and revamped VIDEO_CARDS for fast video accel by default

Recommended Posts

Hey Everyone,

I recently upgraded to a newer Thinkpad Laptop (P1) and decided this was a good time to upgrade Funtoo's graphics stack to sort of finish the work that TemptorSent had started. You'll recall that if you tested 1.4, media-libs/mesa could be quite picky with USE vars/VIDEO_CARDS settings. This should now be fixed.

One thing that bugged me when I installed Funtoo on my P1 was that video acceleration wasn't working well. So I've tried very hard to address this so that "out of the box" with minimal/no configuration, you will have good video acceleration support in Funtoo.

New documentation on this system that is now in 1.4 can be found here: https://www.funtoo.org/Make.conf/VIDEO_CARDS

In particular, see here: https://www.funtoo.org/Make.conf/VIDEO_CARDS/Mix-ins (This table is also included in the main page linked above.)

You'll also see extensive documentation on the new VIDEO_CARDS settings that are available and all map directly to a particular graphics driver now (eliminating confusion between gallium and DRI drivers that existed.)

The workstation and desktop flavors will now auto-enable Open Source Intel integrated graphics (DRI) and Radeon Gallium graphics (Gallium) -- enabling Vulkan for both. I did not enable nvidia or nouveau by default as I leave this choice of proprietary vs. open source to the user (for Intel and Radeon, the best choices are obvious so safe to enable these.)

This should be a big step towards getting everyone optimal video performance in Funtoo without significant work! Be sure to give https://www.funtoo.org/Make.conf/VIDEO_CARDS/Mix-ins and the parent page a good read. And if you use firefox, play around with the h264ify plugin to optimize YouTube video playback and see if it helps reduce your CPU usage.

Enjoy!
