I just followed this How to get byobu to launch tmux instead of screen? and updated byobu on my Ubuntu 11.04 64bit notebook.

When I was using the old version from Ubuntu repos, there always was this colorful status line. With the new version, I no longer see it. I selected tmux as the backend, but the result looks like a bare-bone screen.

Furthermore, F9 shows only 4 options:

  • Help
  • Toggle status notifications
  • Change escape sequence
  • Byobu currently does not launch at login (toggle on)

BTW, here is what I have in my $HOME/.byobu:

zperry@nb1:~/.byobu$ ls -l

Any hints as to how I can recover the colourful status line, and these missing options?

I became curious about this zero-sized file status.disable, so I mv-ed it to no.status.disable and got back the colourful status line. Nevertheless, I still don't see a way to recover these missing F9 options, such as setting background/foreground colors. – Zack Perry May 28 '12 at 17:35
The byobu-quiet --undo did remove the status.disable file, but tmus chipped in and generated some warnings: tmux: unknown option -- X usage: tmux [-28lquvV] [-c shell-command] [-f file] [-L socket-name] [-S socket-path] [command [flags]] – Zack Perry May 29 '12 at 16:46

In you case, you have explicitly disabled your status line, as you can tell by the flag file status.disable. You can either remove this file or run byobu-quiet --undo.

It looks like you figured this out and answered your own question in the comment. As to your new question in your comment, we have disabled a few of the infrequently used and hard to maintain menu options, which includes the background/foreground color setting.

To set the foreground/background colors, you have two options now:

  • Press ctrl-shift-F5 to set it to a random 256-color combination
  • Or manually edit $HOME/.byobu/color.tmux

The byobu-quiet --undo did remove the status.disable file, but at the same time I got: tmux: unknown option -- X usage: tmux [-28lquvV] [-c shell-command] [-f file] [-L socket-name] [-S socket-path] [command [flags]] – Zack Perry May 29 '12 at 16:48
Furthermore, I noticed two new issues: with Ubuntu 11.04, neither byobu-tmux nor byobu-screen has the Ubuntu (distribution name) properly displayed on the status bar. With 11.10, byobu-tmux doesn't show anything, almost like what you would get after running byobu-silent! – Zack Perry May 29 '12 at 16:53
Forgot to mention: I first tested byobu's behaviour on Ubuntu 11.10 over a ssh connection. When I went to the machine's console, after a few trials, I got the status bar with byobu-tmux. But once I went back to ssh access, again everything disappeared. byobu-screen however worked fine either direcly or over a ssh connection. I would be happy to provide screen shots if there is a way to attach such pictures. – Zack Perry May 29 '12 at 17:04

I had the same issue, and the problem was solved by removing the screen hardstatus and caption (comment out those lines in ~/.screenrc). Byobu will then put its own hardstatus in their place.
