Hi! Thank you for helping out and testing, unfortunately there is not much to do if it does not work. I don't have the time or hardware to get an older xf86-video-ati to maybe build with xserver 1.20. The reason xf86-video-ati-legacy works with drm-fbsd12.0-kmod is that the updated kmod uses newer APIs etc. At one point, xf86-video-ati was updated to make these work, and when we updated xf86-video-ati in ports to the latest version to get support for more modern hardware,we had to create xf86-video-ati-legacy for use with drm-legacy-kmod. This was always one of those stop-gap measures. > > > > To recap the various combinations. > > With X.Org 1.19.6 + drm from base + xf86-video-ati-legacy everything > worked fine. Yes, because the things that ati-legacy uses that caused it to break was changed between xserver 1.19 and 1.20. > > Now on to 1.20.8, drm from base or drm-kmod-legacy + > xf86-video-ati-legacy: I get a crash. > > Moving to drm-fbsd12.0-kmod, I completely lose HDMI output and DVI > output doesn't work properly (screen flashes continuously, unless I > reduce full resolution): I have to use VGA output (sigh). > > I also tried xf86-video-ati (non legacy): everything seems the same, > except the machine will sometimes hang. > (I have not experienced an hang *yet* with xf86-video-ati, but it's been > to short a time to conclude anything).
