byobu

When I try to start 'screen' or 'byobu', I get the following error message:

$ screen
No more PTYs.
Sorry, could not find a PTY.
[screen is terminating]

I seem to have enough though:

$ ls /dev/pts  
$ cat /proc/sys/kernel/pty/nr
0
$ cat /proc/sys/kernel/pty/max
4096

Some more info:

$ uname -a
Linux cube.mydedi.net 2.6.18-194.8.1.el5.028stab070.5 #1 SMP Fri Sep 17 19:10:36 MSD 2010 x86_64 x86_64 x86_64 GNU/Linux

If you need any more info please comment. This is on a low-end VPS, but it used to work just fine, until it stopped working. Everything else seems to be fine though.

That worked, but now I can't re-enable all the f-keys. I found a program byobu-config that brings… >>> More
