  1. I am having the same problem and dmesg output with my Ubuntu rock64 I am also getting errors in Xorg.log as described in What is the connection ?
  2. I have the same problem with a rock64 running the latest Ubuntu XFCE
  3. This is using mpv-gbm, I havent installed the GLES stuff yet.
  4. Hi, and first of all thanks to everyone who's contributed here! By following the procedure in NicoD's excellent video I was able to get 4k video playback working on my rock64 -- truly amazing! However I have occasional segfaults in mpv, which make it unsuitable for regular use. I'd be quite happy to help debug these problems. Also a few questions which may or may not be relevant here: The board, and my monitor, should be able to do 4k@60Hz but I never get more than 4k@30Hz. Any clues why? I have two sound options, one is audio over HDMI which works fine, the other produces no sound. I can also get audio on a USB sound dongle, but never on the onboard 3.5mm jack. Why might that be? If I set the audio sink to HDMI, it reverts to the non-working option after a restart... Guess that's about it for now, thanks again!
  5. Yep, overscan is a pain. I have tried two TVs and both overscan on 720p resolution. Going through the TV settings in both cases reveals options to make the overscan worse, but none to correct it. However they both work perfectly when driven with their native resolution. For one, that is 1080i, which displays beautifully. For the other, which I actually want to use with the OPi PC, it is 1360x768. Odd resolution for a TV but there are quite a few older sets like that around. And if you drive it at that resolution, whether HDMI or VGA, there is no overscan. But will the OPi do that? Well the OpenELEC ROM includes a script.bin to set the resolution to 4k (= 3840x2160 @ 30hz) which translates to mode 28 in the FEX. So there are other modes possible than those listed in h3disp -- I'd very much like to know what they are! You can view the missing bits of the display from another device using x11vnc. This has another advantage -- sometimes something will go wrong when playing a video, and even after exiting mpv a corrupt image will be left covering part or all of the screen, making it hard to use. However the vnc viewer shows the screen as it should be, so you can start mpv again and close it properly, which gets rid of the corruption. Computers that always work right are boring! --Jal
