Hello All,
Would it be possible to run weston on a displaylink device?
I compiled a 3.4-rc5 kernel with:
x301:/usr/src/linux-3.4-rc5# grep DRM.*=y .config
CONFIG_DRM=y
CONFIG_DRM_USB=y
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_UDL=y
And get a text console on a Samsung Syncmaster 2243qw, connected to an
Openrd-client with Debian Sid/experimental.
Executing 'weston 2>weston.error' on that console gives a frozen screen
without clearing it (so all previous types text is there).
'weston.error' contains:
no drm device found
failed to create compositor
As far as I understand, a displaylink device would be the only possible
way to get weston running on an arm device, as arm gpu's are hardly
supported with opensourcesoftware, correct?
