Lubuntu 13.10 Black Screen

Hey Folks,

I've been searching around for a couple of days and can't seem to find a solution to this issue. Fresh install of Lubuntu 13.10 and nvidia 331.49 drivers (these were not fun to get on the system). I just downloaded the game so I'm not using steam. When I start up PA from the command line I get the following:

Code:

INFO Failed to load vertex shader file: particle_quad_velocity.vs
INFO Failed to load vertex shader particle_quad_velocity.vs for technique velocity

A window opens but the screen is black and nothing appears to be happening. The last thing displayed on the command line is "INFO Got Expose event" until I close the window. There is nothing in ~/.local... crash log for the game. I checked and that file is in a PA sub folder. Graphics card is a nvidia GTS450 with 1GB VRAM.

Any thoughts?

Thanks,

Most likely CoherentUI_Host can't find libudev.

I linked /lib/x86_64-linux-gnu/libudev.so.1.3.5 to /usr/lib/libudev.so.0 to ../PA/host/libudev.so.0

Isn't the /PA/host directory where it is supposed to be linked?

Yes. Is it still not working?

I just have it on Lubuntu 13.10 with low-end Nvidia GT 430 and work fine.

Also to be sure can you run game and then check if Coherent processes here, e.g "ps aux | grep Coherent".

I tried the linking before posting and have tried a couple of different nvidia driver versions with the same result. I started PA and ran "ps aux | grep Coherent" and it is running.

There should be 7-8 Coherent processes, correct?

There is only one and is seems to persist after I close the window.

It's mean that's actually problem with Coherent startup.

Are there any packages I should get or some workaround?

Not sure why but I deleted PA and reinstalled and it seemed to work. Strange?

To be fair have no idea, might be it's extracted with errors?

I'm thinking it was the extract process that got messed up. Seems to be working well now. I'm surprised how well a crappy celeron and a $50 video card can run the game.

You might try to use __GL_THREADED_OPTIMIZATIONS=1. Sometimes it's can improve performance a lot (and sometimes make it even worse).
