Have you examined xorg.0.log to confirm which driver is actually running? Do you have multimedia/libva-intel-driver installed? If so, is HYBRID enabled in the configuration? I had hangs with it in the past, but it's been working for over two days now with a recent 12.0-STABLE (r342382), mesa-18.3.1 and modesetting. Also, I run with SCHED_4SD, not the default SCHED_ULE scheduler. Are you running SNA or EXA? xorg.0.log might provide some useful information. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
