Linux Support

[Na-Fiann]

Hi,

it's starting with me with no sound. Which is weird, because in the beta I had no problems.
I just tried the beta again, and it's the same there.

I've checked the logs and it's saying it can only find the oss device, even though openal soft is installed and pulseaudio too (I'm running ubuntu karmic, with the latest sound drivers)

running padsp /opt/Osmos/Osmos works of course, but I'd rather see it use pulseaudio directly (which is my openal default).

Hi Na-Fiann,

Welcome to the world of audio under Linux. Unfortunately there are many OSS drivers which stink and don't allow you to have two apps open at once playing sound. So if you e.g. close your webrowser, then launch Osmos, you'll probably be okay.

But I'm surprised your machine doesn't have multiple OpenAL-supporting devices. Osmos will try to open OSS, but if it finds it unopenable because of the above driver bug, it should fall back to another device.

Can you please paste the contents of your Osmos log, which at startup lists all OpenAL-supporting devices on your machine?

Thanks,
Dave

@ mimox: Sadly the Linux world is struggling when it comes to audio. Do have any other options sound device options other than OSS and PulseAudio?

[Na-Fiann]

Yeah I know, ossv3 sucks, ossv4 still doesn't have many drivers and isn't widely accepted.
However, I expected openal to find my pulseaudio, and try that instead. (because I set openal default as my driver in the config file)
here's the log of one attempt (the rest are similar)

hmmm, well according to that log file, OSS is the only OpenAL-supported device being reported by the OpenAL API.

So you do have PulseAudio installed? I'm afraid I'm no Linux audio expert, and therefore not really able to give advice on how to correctly install and configure devices for OpenAL support...

Not a permanent solution, but until you can sort out the PulseAudio/OpenAL woes, can you verify that any other apps that might be doing audio playback with OSS are closed, so that the OSS device can open properly?

Are you using any experiemental/non-standard kernal/sounddriver/etc modules?

Hey guys, just like to comment that I'm really grateful for you porting Osmos to Linux, it's one less thing to boot into windows for I did however buy it on steam, but when i'm temporarily not a skint student i'll be sure to get it. In hindsight I should have got it direct from you anyway, I prefer giving more money direct to indie developers.

Thanks for the game and thanks for the Linux version!

Wow. Thanks for this, what a great game! And for linux! I'm using gentoo, with nouveau and oss and the game works out of the box! (well, not box but download).

I really hope you get plenty of support and make more linux games

I have also freezes sometimes.
"game just froze... no notifications etc, no idea what caused it. I could alt-tab out of the game and kill it on the terminal"

Isnt there another "log" level?
i could reproduce the crash and paste the log here...

whatever...here the..."small"-logfile

<-- End of the log when the game crashed... not very helpful

and THX!!! for the non-wine linux port...

Just bought it, thanks for making a real GNU/Linux port =D

Unfortunately, I'm having some trouble. It seems to start up correctly, see my Osmos.log and Config, but it just runs syrup slow; takes several minutes to get to the Newton quote. I ran windowed and made it as small as possible, that was slightly helpful, but so laggy I gave up on actually playing.

I'm running Arch Linux 64-bit, with an integrated Radeon HD4200. Games like Supertuxkart run fine. My hardware and configuration is described here. Anyone else have a fix, or know how I should debug this?

[Meal Worms]

Thanks for the kind words folks!

@dna: Looks like the game is crash during sound loading. Can you please verify that your sound drivers are up-to-date? Also, can you try specifying a different choice of sound device, by opening the Osmos config file and changing the 'soundDevice' parameter to a different device index, as reported in the Osmos log?

@kiwibird: Osmos makes heavy use of framebuffer blending, which ATI cards have been known to support poorly in their drivers. Can you please verify your drivers are up-to-date? Are you using open-source drivers or the official Catalyst drivers from ATI?

Thanks,
Dave
