I recently got the same problem as in this question: Keep running out of disk space => xorg-session.log
The solution presented there is no real solution, so I investigated the problem further. The topic is also closed, so I needed to create a new topic.
Situation is this: If VLC shows a video, and the computer goes to sleep, after waking up it can’t refresh the video. Instead it floods this error:
vdpau_chroma filter error: video mixer features failure: An invalid handle value was provided.
vdpau_chroma filter error: video mixer attributes failure: An invalid handle value was provided.
This is repeated rapidly, resulting in millions (!) of log lines in minutes in xorg-session.log. So the solution presented in the mentioned question, to open VLC in a console, does kind of work, because the errors don’t go to the log file but remain in the console.
Apparently it would be better to address the error itself, but here I’m out of my bounds. Would it be possible to reset the graphics card after waking up from sleep? Or telling the log file a maximum size? Or telling VLC to stop spamming the same error over and over and over?
And where to report this bug? At KDE? Or Nvidia? Or VLC?
Thanks in advance.
