https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278212 --- Comment #4 from Tomasz "CeDeROM" CEDRO <tomek@cedro.info> --- I have tried to create a Fallback xorg.conf just to have a usable machine to work on when amdgpu bugs pops out. I use UEFI boot so SCFB can be used. Some problems that I have encountered so far looking for a solution with ma= nual xorg.conf: 1. SCFB does not support multiple display outputs. I have two monitors setup required for work. Secondary monitor is rotated. 2. Having two monitors active requires kldload amdgpu. Both are cloned by default. I could use scfb on top of that but also Screen1 is removed as VGA arbiter does not support multi-card setup. 3. Because I failed at SCFB maybe AMDGPU can be still used with reduced functionality (i.e. acceleration disabled). But then it turns out when Acce= l is off the secondary screen rotation is impossible :D :D So far I have set DRI= to 2 and will see what happens. On next crash I will disable/change other feat= ures lised in man amdgpu. If anyone knows how to create a fallback configuration based only on SCFB t= hat would work with multiple screens and one of them rotated that would be real= ly nice so folks can still work on Xorg even no acceleration :-) By the way I have tried Wayland / Wayfire just to make sure the same problem occurs. I managed to start Firefox and crash did not happen. But I did not = work a lot on that setup its kinda clunky :-P --=20 You are receiving this mail because: You are the assignee for the bug.=
