Here is Xorg.0.log in case it is useful [ 6.292] X.Org X Server 1.19.2 Release Date: 2017-03-02 [ 6.292] X Protocol Version 11, Revision 0 [ 6.292] Build Operating System: Linux 4.9.41-v7+ armv7l Raspbian [ 6.292] Current Operating System: Linux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 G...

This is more of a bug report than a troubleshoot request, but because the whole pi locks up I don't really know where to file it. Basically using xrandr to switch modes followed by mpv to play a file nearly always loks up the pi. My steps to reproduce (probably not all necessary) Install 2017-11-29-...

Thanks! That's exactly what I was looking for.

Thanks.

What I would like is the amount of free memor...

Is there a better way of obtaining GPU memory usage than using `vcdbg reloc`? Since that requires that you flush the cache first, it's not reliable. The vcgencmd mem_reloc_stats and mem_oom commands are useful, but it would be nice to get the usage before we run out. I notice there is a mem_test com...
