Initial roundtrip failed!: NoCompositerListening

[Jiří Kozlovský]

Hi,

I've successfully installed (and tried out) yofi from sources, but after some additional packages installation (on Ubuntu 21.04) and reboot I get this error, being unable to run yofi at all :/

RUST_BACKTRACE=full yofi --verbose
# note that the /tmp/yofi.log exists, but is empty

Resulting output of the command above is:

thread 'main' panicked at 'Initial roundtrip failed!: NoCompositorListening', src/main.rs:111:14

It might be related, but I've installed tlp for power management and acpi-call-dkms.

Hmm, after some investigation, it looks like I'm unable to run Wayland session anymore. For some reason, I cannot see the option of Ubuntu (wayland) at the login screen.

Also, when inspecting running processes, there is no XWayland as usual. so that might be that cause.

I think the above error message is the result of running inside a X11, so #23 is probably related to this issue.
