https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249357 --- Comment #28 from Jason W. Bacon <jwb@freebsd.org> --- FYI, I was able to get Xorg working on the X120e with the following contortions: 1. Manually kldload amdgpu. This was just a "Hail Mary". For some reason, this sometimes allows Xorg to start without freezing the system. Adding it to kld_list in rc.conf still causes a freeze during boot. 2. Run Xorg -configure as a shortcut for generating a driver config. 3. Extract Device section from Xorg.conf.new and replace "radeon" with "scfb". Install fragment to /etc/X11/xorg.conf.d/40-driver.conf (actual name not important). Section "Device" Identifier "Card0" Driver "scfb" BusID "PCI:0:1:0" EndSection BusID will be different for each machine. I got it using Xorg -configure, but it will also be reported by pciconf -lv. Look for class=display. Using pciconf to get the BusID will avoid the need to run Xorg successfully before forcing "scfb". Radeonkms and related modules are auto-loaded when Xorg starts, but with scfb forced in the config, Xorg does not freeze as it did with the radeon driver. -- You are receiving this mail because: You are the assignee for the bug.home | help
