Problem launching Eschalon

I had been playing Eschalon on my Dell PC with Ubuntu 8.04, but when I upgraded to 8.10, it stopped launching.

Here is the error I am getting.

Code:

chris@chris-desktop:~/eschalon_book_1$ ./eschalon_book_1
Setting sound driver: Default
eschalon_book_1: ../common/dri_bufmgr_fake.c:576: dri_bufmgr_fake_contended_lock_take: Assertion `((&bufmgr_fake->on_hardware)->next == (&bufmgr_fake->on_hardware))' failed.
Aborted

Any guesses? I checked to make sure libstdc++5 was installed, and I tried deleting and re-installing the program, along with deleting the saved game file.

We haven't updated here in the studio yet. I'll upgrade this weekend and let you know what I find.

Update: We do in fact have one machine here that already has 8.10 on it- Book I loads fine on it. Double check your drivers (sound and video) to ensure you have updated version for 8.10. Perhaps do a search on your distro's support forums and see who else is having problems.

If I hear of anyone else having this problem, I'll post the info here.

Just a quick note. I tried installing eschalon on a HP dv6000 notebook with Ubuntu 8.10, and I got the same error message.

I will look into the driver issue.

thanks

I'm by no means an expert, but "dri_bufmgr_fake.c" sounds like it's in Mesa to me. Try making sure you've got the most up-to-date Mesa package for your distribution. However, given that DRI is involved, it might also be worth checking for an updated kernel, just in case it's some knock-on effect of the in-kernel graphics drivers.

This is a little beyond me. It looks like Mesa is installed, but I'm not sure that I'm using it.

Looking at some unrelated posts on the Ubuntu forums, I determined this about my config.

Does this mean I am using the native glx driver instead of mesa? For some stupid reason, the Intrepid has taken away the xorg.conf file (or, at least, made it useless), so I don't know what X is using.

Here is the information I can gleam on the sound.

It's a little beyond me, too, I'm afraid - I just googled that assertion, and tracked it down to a line in the Mesa source code. I'm not nearly familiar enough with that to determine why it might happen, but just thought that it was worth mentioning.

Even if you're using DRI, it's probable that you'll be using some parts of the Mesa library - I think most DRI 3D drivers are based on Mesa, and just implement a subset of the OpenGL functionality using direct hardware access.

Anyway, I don't want to speculate too much about things I'm not familiar with. My usual policy, however, in cases like this is just to try to update everything vaguely related to the most recent stable version - that includes kernel modules related to graphics rendering and DRI, as well as Mesa drivers and X-Windows in general.

Blindly updating things is never a very satisfactory solution, but sometimes I find it's quicker than trying to figure out exactly what the fault is.

I don't think there's a driver loaded which is supporting your card. That UNCLAIMED means that lshw couldn't find such a driver, and I'd expect it to list the drive on the "configuration" line as in the case of my office PC:

Code:

  *-display

       clock: 33MHz
       capabilities: pm msi pciexpress vga_controller bus_master cap_list
       configuration: driver=nvidia latency=0 module=nvidia

Note that last line, where it lists the "nvidia" driver.

With a teensy bit of guesswork, it looks like it might be the i915 driver you want. Try running the following as root:

modprobe i915

Then restart X-Windows and see if life's any happier. If you still don't get any joy, try attaching the output of this command to see if it's got anything handy in it:

glxinfo | head -30

Not at all - it's highly unfortunate, and something of a failing of the Linux community, that you have to know so much to figure out what's wrong. The community is, in general, very helpful, but it's fractured into so many different separately-managed projects and distributions that it's quite hard to know where to go to get the help you need.

It's a real shame, because I'm really quite fond of Linux. I've mucked around in the bowels of its networking stack too much to say that I think I really like it, but it sucks a lot less than a lot of other operating systems.

Oh no, I LOVE linux. I hate troubleshooting Microsoft products. Step 1- replace so-and-so dll, Step 2- wipe drive and re-install OS. Step 3- blame Hardware manufacturer.

Back to the issue.

The modprobe command didn't seem to help. I ran a utility called xdpyinfo, which seems to give me output similar to the old xorg.conf file.

So, it looks like Mesa is being used for OpenGL, in regards to DRI.

Just to be clear on the problem....I should probably backtrack some....When I try to open eschalon, I get a black screen in the area where the configure screen use to pop up. Sometimes, and I'm not sure when, I hear the first note of the music that plays, then it stops suddenly.

Thanks for all your help.

Update, although not much of one. I have a partition on my computer running GOS, (which I used so rarely, I forgot it was there!). Anyway, I believe GOS is built off of Ubuntu 8.04. I installed Eschalon there and it runs fine.

Not exactly a solved issue. I will still work on getting it to run in 8.10, but at least I can sit back, pour a beer, and enjoy an evening of Eschalon now!

I think that Ubuntu 8.10 switch to PulseAudio, which, from what I've read on the Ubuntu forums, has caused all kinds of problems for people.

I will explore this.

First, you'd probably be a lot happier trying to run this game with current drivers -- kernel from linus master, and libdrm, xf86-video-intel, and mesa from master. That would definitely avoid this message. The Q3 release with the updated kernel would also work. It may also be fixed in mesa master alone -- if I remember right I fixed one bug that produced this. With all of those components the game runs, but slowly (I'd love to chat with the devs about how to fix this), and I was getting about one assertion failure per map exploration due to a bug I haven't quite isolated yet.

(the other way to produce the assertion failure above was to do multithreaded OpenGL using multiple Displays from Xlib, which I don't see a correct way to handle in Mesa. I don't think this game's doing that, and I sure hope not!)

The kernel driver doesn't actually attach to the pci device due to hysterical reasons. That'll be fixed in 2.6.29.

No, X does that for you.

How do I install the correct drivers? I've been a linux desktop user for a long time, but I'm not an expert. I have kept my system up-to-date with the kubuntu 8.10 repositories, but I don't know what to do beyond that.

I also have this same problem in the demo on Ubuntu 8.10. Eschalon was able to launch in 8.04 but it crashed frequently, which is partly why I got around to upgrading to 8.10. But with this dri_bufmgr_fake_contended_lock_take assertion error it doesn't launch at all.

I'd be very happy if a workaround was found! I appreciate anholt's reply, but I don't know what to do with his suggestions.

This sort of bug is unfortunately really hard to track down without being able to reproduce it, and for that I suspect you'd need specific hardware. In any case, it definitely looks like issues with the X11 drivers, and not with the game itself at all.

Hunting around a bit more, I found this bug report which looks very similar:

http://bugs.freedesktop.org/show_bug.cgi?id=17583/

That bug mentions that it doesn't happen with a GEM kernel, so I'm assuming it's some inherent race condition or other similar type of bug in the existing code, and potentially one that they're not planning to fix any time soon, since upcoming code changes solve the problem anyway.

Unfortunately, of course, that's cold comfort for anybody who has an existing Linux distro and wants things to just work!

Unfortunately, I'm not sure what to suggest. It sounds like 2.6.28 will have GEM support, although I'm not familiar with GEM at all - it's something I spent five minutes Googling, after reading about it in the bug report. However, that version isn't even stable now, and once it is, it'll take some time for the major distributions to upgrade to using it. Also, it may be that the Xorg code might need substantial changes to support it - who can say. In any case, it's not like this new kernel is going to be a viable fix in the immediate future.

Unfortunately I can't find any other reports of this problem, so for now it looks like it's just an inherent issue with that graphics hardware on Linux. I'm sorry I can't be more helpful!

As a random aside, I wouldn't be surprised if this sort of bug starts to bite a bit more often as time goes on, since improvements in hardware become increasingly based on parallelisation. For reasons I've never quite understood, a lot of coders find it very tricky to write multi-threaded code, and yet that's going to become really important if software wants to take advantage of the speed increases in CPUs and, I suspect before long, graphics hardware (if not already). I guess it'll just take awhile for people to adjust.

In the meantime, I can only say I hope they produce a resolution for this issue soon, because I haven't seen one yet. Sorry!

Thanks Getharn. I'll try Eschalon again when kernel 2.6.28 comes out.
