| X Error: BadDrawable (X_PutImage) |

I installed allegro 5 from the Debian packages, and a small example program causes the following output at exit: 1 enno@debian:~/allegro$ ./tests
2 X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
3 Major opcode of failed request: 72 (X_PutImage)
4 Resource id in failed request: 0x1800002
5 Serial number of failed request: 43
6 Current serial number in output stream: 46
Since I'm running Debian inside Virtualbox, I suppose there's a chance that this is related to bad X11 graphics drivers, but surely I can't be the first person to do this? Is there a solution? Source below, for reference. When I remove the al_flip_display() call, no error occurs. 1 #include <allegro5/allegro.h>
2 int main(int argc, char **argv)
3 {
4 ALLEGRO_DISPLAY *disp = 0;
5 if (!al_init()) {
6 return -1;
7 }
8 disp = al_create_display(640,480);
9 if (!disp) {
10 return -2;
11 }
12 al_flip_display();
13 al_rest(1.0);
14 al_destroy_display(disp);
15 return 0;
16 }

All I can tell you is that that code looks fine, and it works fine on my (debian-based) non-virtualised Mint 14.2. system. At the moment I don't have a virtualbox debian image laying around to test on. -- |

I always chalked it up to driver issues, but perhaps there really is something wrong with what Allegro does that only shows up in a virtual environment. That said, this isn't the only place where such errors happen. E.g. ex_multiwin reliably causes a quit-time X error as well on my system (even if not virtualized). I don't actually know how to easily debug these issues, as these errors are somewhat asynchronous. We'd have to sync every X11 call I guess to really nail it down.
