CAVEAT: I am a linux neophyte. I've been at it for a few weeks, but I'm by no means an expert. Your mileage may vary, read everything twice, and take it with a grain of salt...

Hokay. After a little nudging from Sevarus in a conversation yesterday, I caved in, installed Envy, and allowed it to do its magic with my display drivers.

As of now, I'm running an msi neo4 platinum motherboard, athlon 64 3500+ single core cpu, 8800gtx/320 (evga acs3 version), m-audio revolution 7.1 sound card, with ubuntu 7.10 x86 (amd64 someday, but not yet. next motherboard perhaps, when I increase memory).

nvidia driver is updated to the new 169.07 variant.

my sound settings for ubuntu are all switched over from default or auto, specifically to use ALSA via the System-Preferences-Sound widget.

cedega is optimized according to Sevarus James little guide, just above (sticky). In particular, I'm set for ALSA sound, and have replaced 'hw' with 'default' in the fields.

Graphic Content Settings in the eve client... cache size is set to extreme.

At this point, you should have an extremely stable client, with minimal graphics glitching. (only thing I saw this evening was a few instances of warp graphics being slightly weird. in two different ways, but both eventually disappeared and stayed gone. utterly odd.

I have the feeling, a lot of the sound issues are being caused by the default ubuntu setup which defaults the system preferences to auto or OSS in some instances. Forcing them to ALSA, along with cedega, makes the system and cedega play nice with one another. OSS doesn't like to share resources, in particular. If a program using OSS already has the sound card in use, and you try to run EVE, eve WILL freeze, at the login screen, right before it would otherwise play its first sounds. This will be at the login screen, unless you have music disabled in the settings. With the music disabled, it will most likely freeze right after character select (untested) Not sure with the updated client, most likely after character select, though.

All this, is of course, 'fixed', if you run eve with no sound.

From another post I was reading earlier, Kubuntu users beware. Apparently the K sound system, 'aRTs', if I understand it correctly, assumes exclusive control of the sound resources, in order to play back system sounds. And, of course, when you try to run EVE whilst still set for OSS, the two fight like dogs, and you, the viewer who paid good money for this dog and pony show, are the one who loses.

Note. It is QUITE possible, that this is responsible for a lot of 'random crashing' that users are otherwise experiencing. If you have another app that tries to grab the sound card, or if the system does, while EVE is running... that could easily be enough to cause problems, especially if the rogue app actually gets access to the card.

So check your system sound settings, and see if this might be causing you an issue. In particular, if you're otherwise stable with sound disabled, and not stable with sound running, this might be part of your problems.

I've been beating my head trying to figure out why so many people are still having crash problems, after that 1.01 patch for us linuxheads... got to thinking a little bit ago, and this popped out.

Good luck, folks.

Oh, one thing, check your pixel and vertex shader versions that cedega is using to run the client. Mine defaulted to 1.4 and 1.1, respectively, for my 8800gts... when of course, it should have defaulted to 3.0/3.0... probably a safeguard for stability, but I've noticed no change in mine, since setting them to match my card. Oh and no, I didn't mispell. Apparently f e g... is filtered :/

I use ALSA in both cedega wrapper and wine.
All OSS programs perfectly interact with others (i don't have alsa-oss package installed, but it seems debian has other way to forward OSS streams thru ALSA).

But eve randomly freezes with enabled sound (can't remember if eve freezes in cedega or not). I have audigy 2...
It started to happen since last audio engine update (months before trinity afair). Not fair, i like to play with sound :P
