[Raspberry Pi 4] KODI does not start

[doragasu1]

I have installed kodi-rbp4 on my RaspberryPi 4, enabled the service and started it, but it is not starting.

On boot, or each time I try manually starting the service, this error is printed 3 times on the screen:
$this->bbcode_second_pass_code('', 'ERROR: Unable to start the GUI. Exiting').

I have tried manually starting kodi in standalone mode with the following command, with the same result:
$this->bbcode_second_pass_code('', '$ WINDOWING=gbm kodi --standalone --debug')

The crash log shows among other info, the following:
$this->bbcode_second_pass_code('', '2019-09-07 18:59:16.952 T:2977251344 ERROR: CWinSystemGbm::InitWindowSystem - failed to initialize Atomic DRM

Why it is not starting? I have installed neither X nor pulseaudio, but they are not required to use it as standalone with GBM, as far as I know. Maybe there is some kind of problem with the DRM layer?

Post your /boot/config.txt

I suspect you omitted what pacman told you: https://github.com/graysky2/PKGBUILDs/b ... nstall#L10

Got another SD card, made a new alarm install from scratch, added the following to /boot/config.txt:

$this->bbcode_second_pass_code('', 'gpu_mem=320
dtoverlay=vc4-fkms-v3d
dtparam=audio=on')

And Kodi starts. But doing the same on 3yo install does not work...

Although I got it to start, after spending a lot of time on configuration and database update, I discovered with pain that as soon as I try to play a movie, oom killer kills kodi-gbm, causing it to restart.

I thing giving 320 megs of RAM to the GPU is way too much. If possible, I would like to use only 1 HDMI output and restrict it to Full HD, I suppose doing it should allow reducing the amount of RAM reserved for the GPU.

EDIT: I have lowered the reserved RAM to 160 MiB and it seems I can play Full-HD content without a problem. In fact while playing, I have almost 360 MiB RAM free, I wonder why it was crashing before.

Depends on the type of video you view; HEVC @ 1080p requires more RAM. 4k is doabled but also requires more RAM.
