Re: [LookForHelp]A10S/ARM Weston-launch failed‏

[Manuel Bachmann]

Hi Andy,

It looks like Weston is trying to use its DRM backend (which is the
default) to initialize the GPU, but is not finding the device or driver.
You can verify this by doing "$ ls /dev/dri/". If the folder is empty, or
does not exist, it means you do not have a DRM driver for your GPU.

If your GPU has framebuffer support, you can try this as root :
$ weston --backend=fbdev-backend.so

More generally, ARM boards support is tricky, because their GPUs have
specific and sometimes closed drivers. Raspberry PI is a notable exception
(for the support).

Regards.
