$ uname -v FreeBSD 12.0-BETA1 r339438 GENERIC $ which xauth /usr/local/bin/xauth $ Radeon HD 7570M, HP EliteBook 8570p. Following the switch to STABLE I could no longer use a desktop environment. For example: service sddm onestart – results in endless repetition of two lines, comparable to those shown at <https://forum.voidlinux.org/t/solved-sddm-crashes/4471>; and <http://www.pclinuxos.com/forum/index.php/topic,141031.msg1204729.html#msg1204729>; except FreeBSD has the different path to xauth so IIRC what's seen is: … /usr/local/bin/xauth: (stdin):1: bad "remove" command line /usr/local/bin/xauth: (stdin):2: bad "add" command line /usr/local/bin/xauth: (stdin):1: bad "remove" command line /usr/local/bin/xauth: (stdin):2: bad "add" command line … kldunload radeonkms – results in a kernel panic. So I edited my rc.conf, $ less /etc/rc.conf # kld_list="/boot/modules/radeonkms.ko" # sddm_enable="YES" … – changed the startup routine to include CSM (not UEFI alone) and created a driver-vesa.conf as shown at <https://forums.freebsd.org/threads/startx-no-screen-failure.65210/#post-382315>. Now I can at least use VESA.
