After the Greenland video, I see the 'loading' message but nothing ever loads. I'm running Integrated Graphics so that might be the problem but would be good if there's any advice on how to fix this.
Tried with resolution etc turned right down/off
Latest drivers on Ubuntu 10.04.
Let me know if there's any resolution/patch that can be tested for this.

I'm pretty sure that the Mobile 945GM has a GMA 950, which is not capable of running the game I'm afraid.

What's the reason for that?
Anything that can be done?

It does not have the needed technical specifications to run the game so there is nothing that can be done about it. It's unfortunate that a video chip released in 2005 is so limited and so much used in computers released even today. Normal budget video cards from ati/nvidia from 2003 are capable of running Penumbra.

I'm having the same problem, although my video card is currently listed with the verified video cards.

I'm running Ubuntu 10.04 with:

AMD Athlon XP 1800+
1.5 gig RAM
GeForce4 TI 4200 with nvidia driver version 96.43.17

Seems to be a driver issue, if possible try another driver.

The verified video cards list is very old, so it should not be used as a 100% accurate list, as cards that worked back then might not work any longer due to driver updates, new OS and such.

Oh well, running the Windows version under Wine seems to work, so, possible work-around there.

it looks like your drivers are not installed correctly.. As the HPL.log should list "supported" shader profiles and it is not. (hence the profile UNKNOWN errors).. For example my Nvidia 7300 card lists this

Checking Supported Profiles
Profile CG_PROFILE_VP40 is supported
Profile CG_PROFILE_FP40 is supported
Profile CG_PROFILE_ARBVP1 is supported
Profile CG_PROFILE_ARBFP1 is supported
Profile CG_PROFILE_GLSLV is supported
Profile CG_PROFILE_GLSLF is supported
Profile CG_PROFILE_GLSLC is supported
Trying to load vertex program!

Can you please provide the output of glxinfo? ass it looks most likely like the wrong libGL is being used by penumbra (ie.. MesaGL instead of the nvidia GL)
