Q: Raspi / TW Fixed Headless Resolution

Hi, I installed Tumbleweed on Raspberry Pi 3 and so far was unable to setup fixed headless resolution. Using x0vncserver (time to time I also connect real monitor). With Debian Buster this worked fine (/boot/config.txt) hdmi_edid_file=1 hdmi_edid_filename:0=edid-1920x1080.bin "edid-1920x1080.bin" located on /boot partition. On Tumbleweed I had to add this in order to get signal on monitor: hdmi_force_hotplug=1 config_hdmi_boost=4 Instead of "/boot/config.txt" Tumbleweed uses “/boot/efi/extraconfig.txt” Copied "edid-1920x1080.bin” into both “/boot” and “/boot/efi”. Unfortunately, it doesn’t work. Also tried: hdmi_force_hotplug=1 hdmi_group=2 hdmi_mode=82 No success either. Anyone know how to to fix this? Thanks in advance. Andrei
