Now I can't get any of the external displays to come on.
xrandr output before plugging in the TB3 dock:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
XWAYLAND0 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
310mm x 170mm
1920x1080 59.96*+
After I plug it in the laptop's display turns off and after some time one of
the external monitors wakes up (as if it gets a signal) but nothing shows and
goes back to sleep. Then all screens remain off. I turned off/on the monitors
and the signal briefly came on one of them but went back to black and then the
laptop's display came back on. Now the xrandr output is
Screen 0: minimum 320 x 200, current 2944 x 1080, maximum 8192 x 8192
XWAYLAND0 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
310mm x 170mm
1920x1080 59.96*+
XWAYLAND2 connected 1024x768+1920+0 (normal left inverted right x axis y axis)
480mm x 270mm
1024x768 59.92*+
I'm attaching the dmesg output for that whole process.
