How to fix TigerVNC on Arch Linux
Raw
how_i_fixed_my_tigervnc_on_arch_linux.md

If nothing works, try systematic debugging!

Xvnc is the starting place.

The latest docs are here: https://github.com/TigerVNC/tigervnc/blob/master/unix/vncserver/HOWTO.md

Don't put a xstartup file in ~/.vnc; this is deprecated.

Don't have a Xsession file in /etc/X11; this messes things up.

Put your username in /etc/tigervnc/vncserver.users like so: :1=jonathan

Use the systemd service: sudo systemctl start vncserver@:1

Observe logs on the server (second terminal): tail -f .vnc/Z820\:1.log

Then see what is going on (third terminal): ps aux | grep vnc

Here, the display managers maybe messed things up: xinit /etc/X11/tigervnc/Xsession startxfce4 -- /usr/bin/Xvnc :1 -geometry 1920x1080 -localhost -auth /home/jonathan/.Xauthority -desktop Z820:1 (jonathan) -fp /usr/share/fonts/misc,/usr/share/fonts/75dpi,/usr/share/fonts/100dpi,/usr/share/fonts/Type1 -pn -rfbauth /home/jonathan/.vnc/passwd -rfbport 5901

I uninstalled sddm and lxdm-gtk3. Then I arrived at the above state, where now xinit calls(?) /etc/X11/tigervnc/Xsession instead of the equivalent for sddm or lxdm.

The log now hung at Loading xinit script /etc/X11/xinit/xinitrc.d/90xbrlapi. Turns out this is related to brltty.

Remove this: sudo pacman -Rs brltty orca and suddenly, everything worked...
