Complete X.org log

Freedroid RPG svn version as of today partly supports Full HD resolution (some menus are distorted, but basically it works) and it does so with about 58 to 59 fps with Intel Sandybridge on ThinkPad T520.

But when I leave full screen mode by pressing F2 or leaving the game it often happens, that X.org crashes with:

I will try to grab the necessary debug packages in order to get a more meaningful backtrace in a moment.

I now have

Any hints on how to make this backtrace better? Thanks.

Comment 2 Chris Wilson 2011-07-01 14:05:12 UTC

That explains why it is so slow for you... You appear to be using indirect rendering. Check your system configuration to find out why.

$ LIBGL_DEBUG=verbose glxinfo

should give a few clues as to what is wrong.

The crash looks like one of the races that in theory has been fixed with later Xservers/uxa/sna/etc. If you can reproduce it with freedroidrpg using direct rendering, only freedroidrpg itself will crash and is so much easier to debug. ;-)

Comment 3 Martin Steigerwald 2011-07-01 14:35:18 UTC

According to glxinfo I do use direct rendering. Beside that 58-60fps on Full HD resolution 1920x1080 is faster than anything I have seen with FreeDroidRPG so far. With 0.14.1 and 1400x1050 and mesa 7.10, but also 7.11 devel I only had about 28-30 fps.

*puzzled*

Comment 4 Chris Wilson 2011-07-01 23:35:39 UTC

It's always possible that the application itself is requesting an indirect context (through glXCreateContext) or that its environment includes LIBGL_ALWAYS_INDIRECT=1. Both do seem unlikely...

Maybe running freedroidrpg under gdb and putting a breakpoint on glXCreateContext might reveal a bit more.

How do I do this? I come this far:

martin@merkaba:~/Spielen/FreeDroidRPG/freedroid-svn/src> gdb ./freedroidRPG

(gdb) break glXCreateContext
Function "glXCreateContext" not defined.
Make breakpoint pending on future shared library load? (y or [n])

Without breakpoint X.org crashes after FreeDroidRPG has been quit (when I test the quit case of this bug) and there then is no obviously stack when typing "bt full".

Comment 6 Martin Steigerwald 2011-07-04 13:03:38 UTC

Well the breakpoint works, but only once it seems:

(gdb) break glXCreateContext
Function "glXCreateContext" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (glXCreateContext) pending.
(gdb) run
Starting program: /home/martin/Spielen/FreeDroidRPG/freedroid-svn/src/freedroidRPG
[Thread debugging using libthread_db enabled]

Hello, this is FreedroidRPG, version 0.14.1+svn.
This seems to be a development version, so we'll exit on floating point exceptions.[New Thread 0x7fffe9117700 (LWP 24695)]

Video system type: x11.
Using screen resolution 1920 x 1080.

Testing if color depth 32 bits is available... YES.
Breakpoint 1, glXCreateContext (dpy=0xa52f40, vis=0xaa8db0, shareList=0x0, allowDirect=1) at glxcmds.c:311
311     glxcmds.c: Datei oder Verzeichnis nicht gefunden.
        in glxcmds.c


Then on quitting X.org crashes without any further stop at that function.

Comment 7 Eric Anholt 2013-11-22 23:24:28 UTC

Are you still having this problem?  freedroid for me switches in and out of fullscreen fine, but it's correctly running direct rendered for me.

Comment 8 Martin Steigerwald 2013-11-23 10:52:38 UTC

Eric, I have no idea, I didn´t play it for a long time. I do not want to take time to try out at the moment. I suggest we just close it, as you tested it. I can reopen it, should it still be an issue.
