When I connect from a PC with openSUSE Leap 42.2 (sddm as displaymanager) to a server with SLES 12 SP2 some applications hang during start there. These are eog, evince and libreoffice. For eog and evince I found the workaround that I installed gdm and activated this displaymanager. But this is no workaround for libreoffice. After starting only the splash screen occurs and the application is hanging. I could start libreoffoffice when I connected from a PC with Leap 42.1 to the server with SLES 12 SP2. I also tested the following scenarios:
ssh connection from PC with Leap 42.1 via PC with Leap 42.2 to
Server with SLES 12 SP2 -> loffice started successfully
ssh connection from PC with Leap 42.2 via PC with Leap 42.1 to Server with SLES 12 SP2 -> loffice was hanging after start
Although other display managers <may> work,
The general recommendation is to use the Display Manager “lightdm” to support remote connections.
Also, you need to install the xorg x-server.
The easiest way to install everything you need is to use the Remote Administration module in YaST to install VNC. After that, you don’t have to use VNC, you can run any other kind of remote graphical console like X over SSH if you wish.
Thank you for your hint. The package xorg-x11-server was installed yet. After installing and activating lightdm and rebooting I tried it once more. The applications eog and evince worked but not loffice. It was hanging again.
