How to identify process that's sending error messages to terminal?
- by kjo
The following error message occasionally appears in my terminal:
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
...which is pretty annoying.
I have searched online for solutions to this error, without success.
Is there any way to at least identify the process responsible for sending these error messages to my terminal?
EDIT: Let me clarify that, as far as I can tell, these error messages appear "out of the blue". In fact, they appear asynchronously with respect to my interactions with the terminal (more often than not see them for the first time when I return to a terminal window that has been unattended for some time). I'm sure there's a definite, deterministic cause for these messages, but it is not one that I can readily identify. In short, I have not noticed any pattern or regularity to their occurrence. In particular, in my case their occurrence has nothing to do with running mplayer, or any other video playback program. (Please my earlier post about it here.) For one thing, the machine in question is a work machine, and I rarely watch any videos with it. In the very few instances in which I've watched a video on this machine I've used VLC, not mplayer, and these errors never appeared in these rare occasions that I used VLC.
