Krusader is slow when starting or changing tabs

In my case, I think I found out the cause, it may relate to bluetooth.

When problem occurs, I disconnect wireless keyboard and mouse and use buitin laptop keyboard/touchpad (or disconnect and reconnect keyboard and mouse via bluetooth) Kursader runs normal again.

Here is my (amateur) method, and you could try it (or you could find better way).

In my case when problem occurs, even if I reopen krusader it does not go away, so I can reopen it with strace (I’m not familiar with this program though).

  • install strace
  • run:
     strace krusader
    And make a video records what the output is.

Because, when problem occurs, krusader is hanged for a moment, and strace shows what krusader tries to do at that moment.

And in my case, it likely tries to read bluetooth device.
