I wanted to use byobu without the tmux backend so I installed byobu after adding screen to the USE flags. However, byobu does not run. byobu-screen does run properly. Reproducible: Always Steps to Reproduce: 1. Install app-misc/byobu-5.133 with USE="screen" 2. Attempt to run byobu Actual Results: /usr/bin/byobu: line 242: exec: tmux: not found Expected Results: byobu should run using screen as the backend. zakalwe ~ # emerge -vp byobu These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] app-misc/byobu-5.133::gentoo USE="screen" PYTHON_SINGLE_TARGET="python3_9 -python3_8" 0 KiB Total: 1 package (1 reinstall), Size of downloads: 0 KiB zakalwe ~ # cat /etc/byobu/backend # BYOBU_BACKEND can currently be "screen" or "tmux" # Override this on a per-user basis by editing "$BYOBU_CONFIG_DIR/backend" # or by launching either "byobu-screen" or "byobu-tmux" instead of "byobu". BYOBU_BACKEND="screen"
After installing twm and xterm, this problem does not occur - seems to be limited to console installations only, perhaps?
