Tried 2 more methods: 1) Set console resolution in Yast -> Bootloader. 2) nano /etc/X11/xorg.conf.d/screen0.conf Section "Screen" Identifier "Screen0" Device "Card0" SubSection "Display" Modes "1600x1200" EndSubSection EndSection All same, issue not fixed.

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
