Can Ozone work with drm platform on Linux?

[Minggang Wang]

Hi there,

I tried to run chromium with --ozone-platform=drm  flag, but got error log below:

[1384378:1384378:1020/175729.553209:INFO:content_main_runner_impl.cc(973)] Chrome is running in full browser mode.

[1384378:1384378:1020/175730.619004:WARNING:drm_device_handle.cc(88)] Failed to authenticate /dev/dri/card0 within 1000 ms

I built the latest master branch with ozone_platform_drm=true, so can Ozone work with drm platform now? Your help is appreciated!

Thanks for Rob's replay, I past it below. Here I want to clarify my case that I want to enable the ozone+drm on Ubuntu of Intel based desktop/laptop, which is i5/i7 and use the integrated GPU. Is it possible to do that? I read https://source.chromium.org/chromium/chromium/src/+/master:docs/ozone_overview.md, but didn't find how to config the drm for Linux, thanks in advance!

Every Chromebook uses ozone/drm so yes, ozone/drm works on the linux OS in Chrome books.
To run ozone/drm Chrome on Linux, you need to correctly setup permissions for drm and evdev devices so that chrome can take full ownership of the console.

See:

https://source.chromium.org/chromium/chromium/src/+/master:docs/linux/ozone_drm.md?q=nouveau%20filepath:md$&ss=chromium

But if you have an Intel GPU, you don't need to use nouveau.
