mrroland Posted June 6, 2018 Share Posted June 6, 2018 Hi Guys, I tested both the odroid official and armbian images for the XU4. Both run well, but I prefer the armbian image. I have attached my 800x480 hdmi display, it works, but there's a purple line at the left side of the display. ( I think it's one pixel wide) This is not the case with the odroid official image, so I guess it's a configuration issue. I took a look at the boot. ini file, but I don't see anything that rings a bell. Can somebody point me to the right direction? Link to comment Share on other sites More sharing options...
JMCC Posted June 6, 2018 Share Posted June 6, 2018 Most probably a display refresh rate issue. Try to play with xrandr to set different rates. More info here: https://wiki.archlinux.org/index.php/xrandr#Troubleshooting Link to comment Share on other sites More sharing options...
JMCC Posted June 6, 2018 Share Posted June 6, 2018 Another possibility is that you use the accelerated display driver, as the official image does (though ours is a little different). You can do it by running the script from this thread: Link to comment Share on other sites More sharing options...
mrroland Posted June 7, 2018 Author Share Posted June 7, 2018 Hi, Thanks for the reply. First solution didn't work for me. When I wanted to try the second one I discovered that the armbian image from the download section uses a 3.x kernel, so I can't run the script for the accelerated drivers. I tried to install a desktop environment to the nightly build with 4.x kernel, but I couldn't get it to work... But I think it's a kernel issue because the purple line is visible as soon as the boot sequence starts. This won't happen with the official odroid image. I guess I should stick to the official image for now and compile the kernel modules I'm missing for that version. Link to comment Share on other sites More sharing options...
