Error when running server (ABS_X info) #184

Open nicodelpiano opened 7 years ago

nicodelpiano commented 7 years ago

Hello!

When I initialize the server, this is what I get in some cases:

Initializing framebuffer device /dev/fb0...
xres=800, yres=480, xresv=800, yresv=1920, xoffs=0, yoffs=0, bpp=32
Initializing keyboard device /dev/input/event0 ...
Initializing touch device /dev/input/event1 ...
cannot get ABS_X info, Invalid argument

Do you know what could be causing this? Thanks in advance.

Is this x11vnc or a custom server? Is this message from LibVNCServer?

I was given the task to investigate that error, and I realized it's a message from the example given here: https://github.com/kanaka/libvncserver/blob/master/examples/android/jni/fbvncserver.c#L153

Now I can see I'm having an issue with the touch file descriptor. I'll dig this a bit more to see what's causing that to fail.

NB that https://github.com/LibVNC/libvncserver/blob/master/examples/androidvncserver.c needs to run as root. Closing for now, feel free to re-open if there's a persisting issue.
