Don't you have a radeon graphics card? AFAIK, there are some problems with linux radeon drivers.

I have the same problem, with SFML 2 from Github.
Using Ubuntu 10.10 with an ATI card:
Renderer: ATI Radeon HD 4300/4500 Series
Version: 3.3.10237 Compatibility Profile Context

Error is:
Code: [Select]

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server "PX6"
      after 152 requests (151 known processed) with 0 events remaining.


Here is my stack trace:

Any ideas?

I just tested on a Mint 11 (Gnome, 64bit) with a Radeon HD 5750:
Renderer: ATI Radeon HD 5700 Series
Version: 4.1.10665 Compatibility Profile Context

Works fine here, so it's seems to be driver-related, like you mentioned in another topic. Thing is, it works on the bad driver when I use SDL 1.2. Either SDL is using a different X11 interface, or it has some kind of workaround for this bug.
So is this bug supposed to be fixed in SFML 2? I'd really hate going back to SDL...

Thanks so much, SFML 2 is awesome, and otherwise really stable for pre-release software!

SDL 1.2 doesn't use OpenGL at all. Try SDL 1.3 with the "OpenGL" renderer instead.

Thanks for the quick reply!
What I actually meant was that SDL 1.2 creates an OpenGL context if you pass it the SDL_OPENGL flag. I'm using SFML (and previously SDL) just for giving me a window with an OpenGL context on Mac and Linux. All the rendering is done using OpenGL directly, so for me the difference between SDL and SFML is just how the X11 window and the OpenGL context are handled.

Sorry for the thread necromancy, but I still see this bug in SFML 2 RC1. This time on a Ubuntu 10.10 box with a GeForce 8400GS and Nvidia drivers 260.19.06.

The strange thing is, that it crashes even if I don't use SFML at all. I have a statically linked binary with both SDL and SFML (don't ask). Only SDL code is used, and I get the crash after closing the SDL window. If I link the executable without SFML, or with SFML 1.6, everything's fine.

Can you show the stack trace?

Should've mentioned the program doesn't crash, it just calls exit(), returning 1 as exit code. This makes my automated tests fail, so to me it's as bad as a crash. Judging from the stack trace, it seems the X11 calls fail because they're happening too late in the static deinitialization phase.

I thought there was no more X11 Display used in global scope, but there's still one used for global inputs (sf::Mouse and sf::Keyboard). I wish there was a cleaner solution, but I haven't found one yet.

However it seems from your stack trace that a X11 error is triggered, don't you have a debug message in the standard output?

Yes, the debug message is the same as for the original poster (minus segfault), that's why I resurrected this thread in the first place:

Code: [Select]
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 8 requests (6 known processed) with 0 events remaining.

When I run the app so that SDL doesn't create a window, the process exits successfully without any debug messages. This means this problem is very specific to my build, but it also means I cannot use SFML in my projects, as it has to quietly coexist with other libraries. I know it's a difficult design choice, but if I had to decide it I wouldn't do things like calling X11 without the host app being able to do anything about it. Just my 2 cents, though.

Thanks!

That sounds wise, but what modifications would it involve in the API? How would you handle that in code?
