I just did a fresh install of Tumbleweed to a Virtualbox machine. I am relatively new to Linux and completely new to OpenSUSE and Tumbleweed.
I then installed Kapman game from repositories. This automatically installed a number of KDE package dependencies. Although everything appears to work well, as soon as I clear Level 1 of the game, the interface freezes. The sound of the game continues as normal, but the display is frozen. I can move the mouse pointer, but clicking on any items [also outside the game, on the desktop] does not have any effect as they are either frozen or non-responsive because the machine is too busy.
So my questions are:
Is there a way to unfreeze my virtual machine without resorting to a forced reboot through virtual box? I believe there are hot key combinations that should give me control, but not sure what they are. I also think xKill is installed, but I’m not sure if there is a pre-assigned key combination for that. I can’t open a terminal once this happens because the menu and everything else is frozen.
What steps should I take to identify and hopefully resolve the freezing issue? I chose some non-standard options during my installation of Tumbleweed, and I’m not sure if that could cause a problem. My feeling is that this is probably a graphic driver issue. I believe the Virtualbox Guest Additions are installed automatically when one runs inside Virtualbox, and so I think that graphic driver must be in use.
You could switch to text mode via Hostkey+F1 and use kill or killall there to force quit kapman.
I also think xKill is installed, but I’m not sure if there is a pre-assigned key combination for that. I can’t open a terminal once this happens because the menu and everything else is frozen.
I don’t know whether there is a key combo in XFCE for xkill, but if everything is frozen, that probably won’t work any more either.
What steps should I take to identify and hopefully resolve the freezing issue?
The first step would probably be to run it in a terminal window and have a look at the output.

I somehow doubt that if you can play the first level without problems…
But: after finishing a level, a notification is shown (which normally plays a notification sound as well).
Maybe that’s what causes the freeze…
As you are not using Plasma5, you might not have any phonon backend installed. Shouldn’t cause a freeze, but who knows.
So I would suggest to install phonon4qt5-backend-gstreamer, maybe it will help…
I believe the Virtualbox Guest Additions are installed automatically when one runs inside Virtualbox, and so I think that graphic driver must be in use.
Right, the guest additions are included in openSUSE and should be installed by default.
And just for the record: I just started kapman here and don’t get any freezes. Though I had to play a few times until I was able to reach the next level…
When I try to run Kapman in the terminal, I get the following output. Not sure how to rectify this.
QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0
"Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)"
I selected the LXDE desktop, which I think uses Openbox window manager.
Other non-standard options I chose were XFS file system and the Deadline IO scheduler.
I also doubt these options are related to the Kapman freeze…
Yes, I had been playing some Kapman in another distro, so I can usually clear the first level
Just open an xterm (or whatever other terminal application you have installed) and run kapman, do not use su or sudo.
And did you check that phonon4qt5-backend-gstreamer is installed?
As I wrote, if you finish a level, a notification dialog will be displayed which also results in a notification sound by knotify. Having no Phonon backend installed might cause problems.
phonon4qt5-backend-gstreamer is showing as installed version 4.9.0-1.1.
I am able to execute Kapman from the terminal as non-root user. I get the following output as the game starts. At the end of the first level, it freezes with no further output to the terminal.
I do hear the notification sound and if I press the movement keys, I can hear Kapman moving in the next level. So it appears only the desktop display is frozen.
What next steps can I try?
Thanks!

In the meantime, I switched from Virtualbox to VMWare Player, and I am having better results under VMWare. There still seems to be some “lag” in the screen updating after clearing a level in Kapman. However it is not completely “frozen” as it was under Virtualbox.
I will follow suggestions to see if I can further improve the display performance. I’m guessing it is related to the virtual display drivers.
