I tried using the program
glinfo of the
glxinfo package. A new window appeared, but only the window-manager decoration parts; the actual content was blank. The mouse and keyboard no longer responded. A few seconds later the screen filled with a repeating wavy grey pattern. I've found no relevant information in any log files. The console-only program
glxinfo from the same package works fine.
Of course I will avoid using that program in the future, but no matter how buggy an app it shouldn't cause the X server to hang. If this is a bug in X11 or OpenGL I'll file a bug report, but if it's a problem with my configuration I'd like to fix it.
I'm using Mageia 3, with the following relevant packages:
- x11-driver-video-nv-2.1.20-3 (the NVidia driver)
- mesa-9.1.3-1.1 (OpenGL)
