BuggyBY - You may have stumbled across these in your quest - so my apologies if they are redundant :).
On the Mint Forums:

This might be helpful from Linux questions:

And an benchmark article for your graphics set:

Which brings me to ask, what do you get when you run:

Code: Select all

glxinfo | grep renderer
and

Code: Select all

$ sudo lshw -c video
?

Re the LinuxQuestions link, despite the claim that "it is now in Multiverse for Ubuntu and a straight apt-get install on Linux Mint" I was unable to find the cedarview packages. In any case, my Atom N570 CPU seems to be Pineview rather than Cedarview (going by the table on https://en.wikipedia.org/wiki/Intel_Atom), so those drivers might well not work.

I just stumbled across this article from the Vega Strike Development Blog, detailing some of the difficulties in running a 3D space sim on Atom N5xx-based netbook hardware. My own netbook uses an Atom N570, and while VS is of course quite a different animal from Oolite, I can definitely detect some parallels to my Oolite woes. Especially noteworthy is the section on RAM:
This little thingy I borrowed from my sister has an astonishing 2G of RAM on it. It’s the maximum the chip can handle, for those that don’t know, so you don’t get a bigger Atom. VS can run with 1G and some swap, so 2G was plenty. Still, I could feel the poor thingy ask for mercy. Atoms, small as they are, are 64-bit. That makes VS use some more RAM than it would on 32-bit, and on a 2G system with no video RAM whatsoever, it was pushing it.

I think the worst thing is that APUs (and other onboard GPUs too) have to share system RAM with the CPU - they have no dedicated RAM, and that’s a big disadvantage for OpenGL. OpenGL has to keep a copy of all textures in case they have to be swapped out of VRAM, and APUs, which have no RAM but do have reserved RAM are no exception. So all textures use up memory twice - once in system RAM, and once in video RAM. On a 2G system, you feel it. A 1G system would be swapping and stuttering constantly (I’ve tried), and if you don’t decrease texture resolution, even crash.

Which brings me to N5xx APU’s limit of 256MB texture space. This is plenty, but since intel doesn’t support DXT compression (they market it as DXT de-compression, which means the driver expands the texture when loading it into RAM, a big lie that retains none of the benefits of DXT), those 256MB run out quickly.

Full-size planet textures, for instance, use up 160MB on their own. Add a few stations and ships, and texture swapping is pervasive. In fact, I’ve had it crash on me when textures were at full resolution - especially when looking at earth, which has the biggest, bestest and meanest texture set - because if an object’s textures don’t fit in that limit, the driver will kill VS.
Looks like my best hope for stability at this point involves getting rid of Povray Planets. A pity.

That's probably it. I have 2Gb system + 512 Mb video, and on 64-bit that just leaves enough memory to run Oolite+Povray+Griff's. If you have to run video from the system RAM, then you'll have to be extremely careful which graphical OXPs you install.

I don't know if it's practical, and it'd certainly be a big hassle to reinstall everything, but if you switch to the 32-bit version of your Linux distro it might help. It won't be as efficient on the hardware as the 64-bit version would be, but it will use less RAM.

I was told the same on the Linux Mint forums the other day. For now, I've added an extra swap file (as I noticed the swap partition filling up quickly, even with just a few web browser tabs running) and will see if that increases stability once Povray is out of the equation. Fortunately the whole system is fairly virginal in terms of applied customization and installed applications, so switching to a new 32-bit install won't be as big a hassle as it would on my desktop.

Does Oolite/OpenGL have problems dealing with texture memory being swapped to hard disk? I was hoping that the SSD I'm using would at least significantly reduce the dramatic slowdown when accessing swap instead of RAM, but does it really make a difference?

A dumb pilot's thought: do you have all eight Povray sets installed? Would it make any difference if you only had one set at a time installed?

At the moment I have all eight packs installed. Does it make a difference? I thought textures were loaded on a per-system basis, as it would make little sense to unnecessarily cache planet textures for a place that would take several galactic jumps to reach.

Heh... as I said, merely a dumb pilot's thought (a tired one, at that).

Yes. It needs to read that, extremely quickly, thousands of times a second. No matter how fast your disk is, it's not fast enough. (A swap file might be useful to shove the rest of your OS in while you're playing Oolite, but that's only going to get you another 100Mb if that, and probably cause significant slowness any time your OS does need to do anything)

Makes me glad I didn't get an Atom last year when I got a new machine - which I almost went with - I sure am glad things worked out as they did.

How does removing POVray planets work for you BuggyBY?

I didn't notice any difference, the game still crashed with segfault or OpenGL errors in the console. Then I looked at the 3D acceleration options offered by DRIConf and found that I could specify settings on a per-application basis. I enabled the debug option of "flushing GPU caches with each draw call" for Oolite and started the game.

I still got the occasional artifact on screen (a particularly long sequence of them ended up looking rather pretty, with interesting effects on the HUD text), but the game was a whole lot more stable. Whereas the game session had barely lasted three minutes of flying through the Atorat system previously, I was now able to kill my bounty target there, dock at the main station, save and jump through five more systems to Xeraqu (docking and saving at each before the next jump) where the game crashed yet again. So it looks like the GPU cache definitely affects stability, despite not being the sole cause of these problems.

I wonder at what exact point my game had become this unstable. I don't remember such frequent crashes from the first few weeks of playing.

Console output this time:

BuggyBY,

i noticed your graphics driver is the i915.
I've seen many reports of problems with the 3.8.x kernel and that driver, what kernel version are you running ?

(if you're not sure, run uname -a from commandline to get the kernel version).

P.S.
I haven't checked all links in this thread, just ignore if this was already mentioned.

uname -a told me I'm running 3.5.0-27-generic #46-Ubuntu SMP, so issues only affecting 3.8.x kernels ought to be unrelated (unless they were inherited from 3.5 and earlier, of course)

Nope those problems i mentioned only appeared in 3.8.x kernels , the 3.7.x and earlier were fine.

edit : the 3.8.11 and 3.9.x kernels don't seem to have these problems anymore.
