Ok, so after a number of failed attempts, it finally worked, out of nowhere
Now however, I face the problem of:
"(<unknown>:32289): GVFS-RemoteVolumeMonitor-WARNING **: cannot open directory /usr/share/gvfs/remote-volume-monitors: Error opening directory '/usr/share/gvfs/remote-volume-monitors': No such file or directory
crystalspace.sndsys.renderer.software: Failed to load driver as [crystalspace.sndsys.software.driver.alsa] or [crystalspace.sndsys.software.driver.crystalspace.sndsys.software.driver.alsa].
The walktest runs, but very inadequatly, with very low framerates. Hope anyone can help!
