How to resolve KDE Connect App losing connection with Linux after screen is locked on Huawei Phones

Posted on November 22, 2018 by Ahmed Tawfik

I tested on my P10 Plus, but this can work on other Huawei phones as well I believe. I have EMUI 8 with Android 8 and my OS is Ubuntu 18.10 with GSConnect

  • Go to Ignore Battery Optimization -> Change from Allowed to All Apps -> Navigate to KDE Connect and choose Allow
  • Go to Apps -> KDE Connect -> Open by default -> Battery -> Change Launch to Manage manually -> Select all options
  • Restart your phone and open the KDE Connect App

Enjoy!

Best way to exclude a folder from your search using the “find” command

Posted on November 22, 2018 by Ahmed Tawfik

I found it to be the fastest and most effective way to use the find command and exclude specific folders. That is using the “prune” option:

find /FOLDER_TO_SEARCH_INSIDE -path /FOLDER_TO_EXCLUDE -prune -o -name 'NAME_OR_PATTERN_TO_SEARCH_FOR' -print

That’s it, Enjoy!
