Ubuntu 18.04.3 LTS, Video Card Mali G52 Not detected

Unread post by superpowter77 » Sat Sep 14, 2019 2:04 pm

My Screen Resolution was set automatically to 1920x1080. However, 0 Hz refresh rate is shown.
I tried using xrandr to manually set my refresh rate to 60Hz without success. Then I realized my video card configuration was non-existent. Can anybody point me in the right direction how to solve this?. I am new here. Just got my Odroid-N2 board today.

I tried building the Qt5 source code manually as well

inxi -Fxz output

Seems like a defective HDMI port on the Odroid-N2 maybe?, How awesome!. Just tried new different HDMI cables, brand new expensive ones and still getting initial same issue. Tested different TV's, Sony 4K TV's, disabled their High speed 4K hdmi feature for each port, still getting same annoying issues. When I turn it on, sometimes I get random 16 color mode at a crazy 1024x600 resolution. I will tried different distros to see if this is a Ubuntu Mate related issue or it's a bad Odroid-N2 board. I have several devices at home as nvidia shield tv, Rpi 4b, minix android tv box, PS4 pro, Amazon fire tv 4k and I have never seen any device producing artifacts or not being detected by my Sony Android TV's 2016 and 2017 models.More Issues: When I switch between HDMI ports and come back to HDMI port used by Odroid-N2, Ubuntu Mate desktop has been resized(different resolution), looks blurry and shows artifacts on screen. This last issue happens all the time. If I reboot, same thing, Sometimes 1080p resolution works, sometimes it doesn't.

Latest CoreELEC performance was solid as rock. Loaded up successfully every time, when I switch to between HDMI ports, video resolution looks right how it's suppose to be, no flicking/artifacts on my screen anymore, lowered/broken resolution,etc. So far, I have tried 4 different Ubuntu Images, both Mate and minimal, they all suffer from them same video issues. Looks like my Odroid-N2 board is not defective after all, knock on wood. I don't mind getting my hands dirty, tinkering and even compiling code and building libraries, but I do expect to see a minimum set of working things right out of the box like video signal being properly recognized by Distros at booting time. Worst come to worst, at least I have a fully functional an expensive HTPC device. CoreElec Video reproduction quality was simply stunning. Thank you anyway. See ya.

Tried Armbian Stretch as well and since it uses latest Hardkernel kernel, it behaves in the exact same buggy way. The only Distro that properly detects my monitors at 1920x1080 at 60Hz is CoreELEC. Since nobody here seems to be able to try to help my case,I will wait until South Korean holidays end to hear directly from Hardkernel developers about my issue and to know whether I need to RMA this back to them or not!

Getting 0Hz displayed as a frequency is not an issue. You can force a resolution via boot.ini and bypass autodetection.

I just did it, still does Not work, after applying changes and reboot, still shows "0 hertz" under refresh rate.
Edited "boot.ini" from /media/boot/ directory and changed it to false, was set to true by default:

setenv display_autodetect "false"

and since default mode is already set for 1080p and 60Hz, I thought nothing else should be changed.

setenv hdmimode "1080p60hz"

Note: My Sony android 4k TV's are 100% compatible with 1080p at 60 Hertz modes.
CoreELEC detects them correctly at: 1920x1080@59.94Hz

Please advise. Thank you.

Where do you see 0Hz? Under display settings in Mate, or under Kodi?
I think it's just a cosmetic issue. Do you see other problems with the display apart from this?

Mate, of course I had some display issues with it. Miraculously, after running a full system update/upgrade switching between hdmi ports in my Sony TV, no longer resizes and produce a flickering effect that could only be fixed by rebooting as long as right HDMI port was chosen prior to that. Even those annoying booting display issues when HDMI port use by odroid-N2 was not selected, has been apparently fixed. Knock on wood. Still waiting to have HW acceleration for the Mali G52 GPU for a desktop version anytime soon.
