I am using Ubuntu 18.04 (WSL) on Windows 10. I can use the scrollbar with mouse or touchpad before starting a screen session. But, once I start a screen, I lose the scrollbar (gray out).
What I did:
Increase the buffer size from property 50 -> 900 (no effect)
screen -h 50 or 1000(no effect)
tmux seems to have the same problem.
Interestingly, when I ssh into a remote server (SUSE Linux Enterprise Server 11),
screen actually works fine in the same Ubuntu 18.04 WSL shell.
So, I feel there must be a way to get this working in WSL.
WSL Screen version 4.06.02 GNU bash, version 4.4.19(1)-release
SUSE Screen version 4.00.02 GNU bash, version 3.2.57(2)-release
WSL is using more recent versions of bash and screen.
.screenrc files are near empty and contain no configuration related to buffer size or scrollbar.
I know that
Ctrl + A, ESC to enter the copy mode and then scroll up/down with the keyboard (cf. https://stackoverflow.com/a/8760452/566035). But this does not give me a scrollbar and mouse/touchpad do not work in this mode.
