https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220043 --- Comment #3 from Ed Maste <emaste@freebsd.org> --- In my case the system came up at 640x480, with either black or arbitrary pixels in the right portion of the screen. The resolution needs to be explicitly set in the bootloader config, via the following in /config.txt in the FAT bootloader partition: # Force HDMI config hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt=800 480 60 6 0 0 0 These settings magically make their way through to the EFI framebuffer; the loader and vt successfully operate in 800x480 mode. Note that config.txt is parsed by the convoluted set of R-Pi bootloaders, before anything related to FreeBSD (or Raspbian) is executed. -- You are receiving this mail because: You are the assignee for the bug.help
