Hello dear Khadas Team,
I am a proud new owner of a Edge2. Unfortunately running it with the latest Ubuntu software it does not support display resolution of 5120 x 1440 on Philips 45B1U6900CH monitor with a HDMI cabel.
The maximum display resolution that is working on Ubuntu is 3840x2160px
On the Android 13 image 5120 x 1440 works perfectly so I think it is a image-SW issue.
I’ve tried troubleshooting and manually adding the intended display resolution, as explained here: xrandr - How do I set a custom resolution? - Ask Ubuntu but it failes with “ BadMatch (invalid parameter attributes)” – console output see below.
I’m running edge2-ubuntu-22.04-gnome-linux-5.10-fenix-1.6.2-240110 from January 10th and installed all available updates.
Any help on this issue would be highly appreciated
