I thought some x11 specifics were dropped over a year ago from umlibs/DDK, which is in meta-ti and not specific to Arago... But in general I agree that this can be reconfigured with unaccelerated x11 for anyone adventurous enough :) > > On Tue, May 06, 2025 at 07:57:48AM -0700, Sebastian via lists.yoctoproject.org wrote: > >> I've tested meta-ti for kirkstone the xserver starts up correctly into an X > >> session. > >> > >> With meta-ti for scarthgap it fails.
