Hi,

There are few things that would need work:

• evdi will only work on a system which uses drivers compatible with DRM
• evdi has dependencies on drm_kms_helper and drm modules, and needs symbols from them, hence the errors you see
  

  evdi: Unknown symbol drm_framebuffer_cleanup (err 0)
  evdi: Unknown symbol drm_kms_helper_poll_fini (err 0)
  evdi: Unknown symbol drm_open (err 0)
  evdi: Unknown symbol drm_mode_vrefresh (err 0)
  evdi: Unknown symbol drm_fb_helper_single_add_all_connectors (err 0)
  evdi: Unknown symbol drm_fb_helper_init (err 0)

• finally, as you already saw in the release note, the helper application currently only works on Intel platform. Providing ARM support is not impossible, but the driver is targeted at desktop Linux environments, which are Intel based and we're not looking at extending support to ARM at this time. That said, things may change if someone proves that evdi is ready to go and the only component that's left to do is DisplayLink Manager. Feel free to raise an Idea for this through our support page - that would help us see how much demand there is for this.

Hope this helps,
Michal

If someone feels like experimenting, this is probably a good starting point...
