X seems to work without any > issues in v5.1. 5.2 also has support for Panfrost (Mali-Midgard GPUs) but I'm not sure if it already can support X11 yet and your X11 log mentions libglamoregl in the segfault stack trace. Apart from it bisect that Greg suggested you could also just try blacklisting either panfrost or vpu kernel modules /etc/udev/somewhere . This would prevent them from loading Hope that helps Heiko _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
