I guess that following change in drivers/gpu/drm/i915/intel_panel.c, line 1748 on top of kernel 4.6.x (check https://lists.freedesktop.org/archives/intel-gfx/2016-February/087151.html) - if (dev_priv->vbt.has_mipi) { + if (connector->base.connector_type == DRM_MODE_CONNECTOR_DSI) { should solve your issue. FYI this is not part of 4.6.x kernel but part of 4.7 or our drm-intel-nightly. So either you upgrade to a more recent kernel or apply that change (In reply to yann from comment #1) > I guess that following change in drivers/gpu/drm/i915/intel_panel.c, line > 1748 on top of kernel 4.6.x (check > https://lists.freedesktop.org/archives/intel-gfx/2016-February/087151.html) > - if (dev_priv->vbt.has_mipi) { > + if (connector->base.connector_type == DRM_MODE_CONNECTOR_DSI) { > > should solve your issue. I don't think that should make a difference. More likely a dupe of bug 96571. *** This bug has been marked as a duplicate of bug 96571 *** |
