fbvnc only show 'showmsg()' from fbnvc.c

[tomnormbgu]

Hi,
I'm using alpine linux 3.20. Im using Xvnc and Qemu's vnc, in both when I open fbvnc from the TTY I get a black screen with the output of showmsg() from fbvnc.c.
when I press ctrl+space several times I get (discrete) updates to the screen, so I tried to add OUT("1") to fb_set(), and that gives me the vnc screen (but '1' is written all over it when I move the cursor or press the keyboard).
I figured that my framebuffer is updated when I write to it (like in OUT) but not when I memcpy to it (like in fb_set).

The output of fbset is:

mode "1920x1080-0"
# D: 0.000 MHz, H: 0.000 kHz, V: 0.000 Hz
geometry 1920 1080 1920 1080 32
timings 0 0 0 0 0 0 0
accel false
rgba 8/16,8/8,8/0,0/0
endmode

Do you have an idea what is the problem?

Thanks!

Are you using X11 or Wayland at the same time? Ali

[tomnormbgu]

no. one of them at a time. for now I'm only using X11 via Xvnc.
