There were no decent, simple way to report it on launchpad, or automatic reporting, so I post it here, maybe some advanced user cares to forward it so it can be solved before release.
Using Citrix Reciver : icaclient_13.7.0.10276927_amd64.deb
and launching a session by .ica file via brower. (using Citrix portal)
Unity: works fine as always
Gnome: freezes, the crashes desktop back to login.
You should be able to file a bug against gnome-shell which we ship in 17.10 by default. However, I’d imagine this is due to it being wayland by default. Try logging out and back in, but choose the little cog on the login screen and choose “Ubuntu on xorg” to switch back to X. However if that’s the case then this is probably a citrix bug, and not one we can deal with on launchpad.
I’ve moved this to the Support & Help Requests category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using IRC, the Ubuntu Forums or AskUbuntu
