I used to get these random freezes where mouse movements are still possible, but everything else seems to freeze. Haven’t got any recently and it occured very rarely.
However, if I switch to another tty, using ctr + alt + f key and then switch back to the original tty, it seems to fix itself. It might not be related, but worth trying it out.
I think it has to do with the way the Haskell packages are disturbed. So if you installed the pandoc from
extra
repository, and there was an update for any of the Haskell packages that pandoc depended on, then pandoc will have to be updated again. Meaning, instead of pandoc forcing Haskell updates, it is the other way around.If you only use pandoc and don’t normally program in Haskell, check out pandoc-bin. This way you will only get updates for pandoc itself and its dependencies won’t force an update.
