Good news, I’ve finally managed to make HDMI output in my ODROID-XU3 Lite development board with the Ubuntu image, after some more tweaking. so ODROID XU3 Lite Ubuntu review is coming in the next few days. But first, I’ll explain the few steps I went through, in case other experience a similar issue.
I downloaded, extracted, and flashed the latest Ubuntu image to a micro SD card with dd to give another try at running Ubuntu on my board, but not luck, I still got that black screen, albeit the system boots properly, as I got the command line using the serial console.
During my Android review of ODROID-XU3 Lite, I noticed the system would always revert back to 720p60 video output, and HDMI output settings can be selected in in /media/boot/boot/ini with the following content:

I actually tried a few settings in my previous attempt by unsuccessfully. However, now I knew that 1080p does not work in Android with my TV, so I focused on the 720p settings.
Trying 720p-edid, lead to a black screen, but enabling 720p-noedid worked around the issue, and I could finally see LXDE desktop environment on my TV. That means my TV (Panasonic TH-L39EM6T) and ODROID-XU3 Lite board have issues communicating EDID information, and it’s most probably a driver issue that needs to be fixed, but at least, if you encounter a black screen with your board, it’s worth spending some time trying all options in boot.ini.

Great!!!. Finally Odroid Xu3 Lite works in Ubuntu with little tweak HDMI settings.
Good news! I need more reviews from you not from any complicated OS developers.
I also want another Ubuntu review about the ODROID-C1 low cost model.
Look forward to the full review of this board. Exynos 5422 board and kit for under $100!
Looking forward to full review now! =)
[…] testing ODROID-XU3 Lite with Android 4.4, and finding a workaround to some HDMI issues, I could finally try out Ubuntu, or rather Lubuntu with LXDE instead of Unity, in Hardkernel low […]
