Remote desktop session frozen

by lampShadesDrifter   Last Updated July 11, 2018 22:01 PM

My host machine is using Remote Desktop Connection Manager (RDCM) on Windows10. Using RDCM to connect to several remote machines running CentOS7 (and connecting via xrdp (used https://www.itzgeek.com/how-tos/linux/centos-how-tos/install-xrdp-on-centos-7-rhel-7.html to set up)) with their default Gnome desktop GUIs. One of the sessions in RDCM appears unresponsive to any cursor clicking.

Some info on the problem:

  • The session on this problem machine appears to be frozen after several days of remaining connected and working fine (while all of the other are OK).
  • When I move the cursor over this remote GUI session, the cursor changes to look like how it should in that OS, but I cannot click on anything or interact with anything in the remote desktop in any way
  • (and I am unable to use the remote OS's hotkeys to try anything because they only register with my local Windows OS).
  • Sometimes mouse clicks will work, but when able to click, in say a text document, the key-presses seem to go unregistered.
  • However, I can still ssh into this machine via terminal, but would like to avoid a hard KILL of the session in the interest of saving data that is not saved in that session.
  • Firewalld is inactive.

Has anyone had this problem before? What can be done to fix this?

This seems to be a common issue with gnome (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=675345 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767173). What seems to help is using another terminal on local machine to ssh into the remote and restarting the gnome desktop manager via systemctl restart gdm.service. After a minute or two, going back to the frozen remote desktop session, it again appears to register mouse clicks.
