[Alt] key problem when remote desktop Windows via Remmina

If you are using Xfce 4 and encounter the following problems using [Alt] key inside Microsoft Windows remote desktop session:

• [Alt] key does not work as per expected
• clicking [Alt] + mouse middle button move you away from your remote desktop session

then you should try this simple and straight forward trick before going too technical.

• Go Settings > Settings Manager > Window Manager Tweaks > Accessibility > "Key used to grab and move windows" > set it to "None"

Voila! Now it should works like charm. Otherwise... you might have to Google around and read about re-map key, etc.. Good luck!

Remmina - Unable to connect RDP Server

Have you ever encountered sudden failure to RDP to your Windows desktop using Remmina? There are two known reasons to me:

1. your RDP plugin for Reminna is missing. In Fedora, type sudo yum install remmina-plugins-rdp, or Ubuntu sudo apt-get install remmina-plugin-rdp. You may require to reboot after install in order to load the RDP plugin. Sometimes Import simply won't work.
2. your remote desktop's fingerprint has changed. It is impossible to reset the fingerprint within Remmina's interface. What you can do is fire up terminal, go to ~/.freerdp/ and delete known_hosts.

Now try again and voila! Your remote desktop is back!
