penumbra.bin - Permission denied!?

[Ozzie]

Well, like on the screenshot, I can see the map on the desk only more or less, sometimes not at all.
Also, the back wall with the porthole is sometimes not visible at all, sometimes only in parts.
The same goes for the lamp and probably many other things (the flashlight looks also weird).
I might try with an older driver, but the one that is in the Ubuntu repository made some other problems with video playback...well, I try.

Edit: I installed two previous driver versions, and they didn't help the problem. Then I installed the version from the Ubuntu repository. With it Penumbra won't even start, so this isn't the way to go as it seems.
It doesn't matter if I use OSS or ALSA, the sound stutters anyway. Maybe it also did under the Windows version, but I can't remember.

As I see it only a patch can fix this problem. Why isn't this patch available for Linux!?
