I can easily switch back and forth, so if you want me to do some test, just ask. In fact, I'd be interested in making this work, but I need some guidance; I can use gdb & Co, but I know almost nothing of X internals. > The reason xf86-video-ati-legacy works with drm-fbsd12.0-kmod is that > the updated kmod uses newer APIs etc. You mean the reason *it doesn't* work? > 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.

And, more relevantly, on my HD4250 drm-12-kmod only works partially. And, even with those limiations, X often hangs. Strange, because I also have a HD4200 which used to work prefectly with non-legacy; I had to switch to legacy when I moved to HD4250. They should be almost the same card, just with different clocks. >> 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). > > Is this with drm-kmod or drm-legacy-kmod? drm-kmod. With this module, I'm able to start the X server, but only VGA output works (even before X is started) and X hangs. I guess the first step would be to fix drm-kmod... bye & Thanks av.
