Running GUI application with xfce session manager (glibc errors)

Hello, I am able to setup a Desktop environment with XFCE, however starting an application with session manager fails with glibc errors. Any pointers would be helpful. Thanks

Hey, sorry we didn’t see this earlier. I think this is the relevant portion of the output log. The app you’re booting (IVG?) isn’t booting or at least shut itself down. Not really sure why (the SLF4J error seems to have corrected itself).
