Midnight commander does not percept mouse clicks

After the last update on our HPC I noticed that Midnight commander run in SSH Bash session (Konsole from KDE) cannot interpret mouse clicks correctly and produces texts like 9:12M9;12m9:12M9:12m. After consultation with Claude two ways of fix have been found.

Disable mouse completely

mc --nomouse

and set the alias

alias mc='mc --nomouse'

in ~/.bashrc.

Get mouse working again

There were different suggestions, the working one is provided below. One dumps the terminal info

infocmp xterm-256color > ~/terminfo

The following text should be removed from ~/terminfo if present:

XM=\E[?1006;1000%?%p1%{1}%=%th%el%;,
kmous=\E[M,

In my case, the first line has been absent, but the second one was the source of issues. The modified file then is moved into its own folder:

mkdir -p ~/.terminfo
tic -o ~/.terminfo ~/terminfo

and the following lines are added to ~/.bashrc:

export TERMINFO=~/.terminfo
export TERM=xterm-256color

Now Midnight commander can be run with the proper interaction with mouse in the terminal.
