I have a problem with Forticlient software on Ubuntu 22.04. Every time I manage to connect my VPN, entire system freezes - no keyboard actions work and the screen just freezes. However, the system seems to be running, because there appear another entries in various logs. I have also tried it out in non-GUI mode and everything worked as it should. That makes me think that once VPN tunnel is established, something hangs GNOME. I cannot find any reasonable cause in syslog and dmesg, it just freezes. No matter if I take open Forticlient or the official packet from Fortinet, the effect is always the same.
Any ideas appreciated.
