<br>
with the fresh x-server patch i just sent out, the EGL + DRI3 problems<br>
under KDE are gone, at least as tested on an old Intel Ironlake and<br>
GeForce Tesla.<br>
<br>
I still see some more problems beyond those, which may or may not be<br>
related to the new DRI3.1/3.2 stuff. On KDE-5 the KDE panel<br>
occasionally freezes/becomes unresponsive, while the remaining desktop<br>
continues to work. This seems to be something recent and only on<br>
modesetting-ddx.<br>
<br>
On intel-ddx + Ironlake i get modesetting failure at server startup,<br>
but only under DRI3, and not with modesetting-ddx. The kernel drm-next<br>
kernel seems to complain about unsupported tiling formats for the fb.<br>
On NVidia Pascal i also saw modesetting failure, but not on older<br>
Tesla gpu's.<br>
This needs more testing.<br>
