I ran the following script in the shell:
while true; do cat /proc/meminfo | grep MemFree:; sleep 5; done
and this is what I saw before I got disconnected from the shell:
MemFree: 148208 kB
MemFree: 148304 kB
MemFree: 146660 kB
Connection to nps-server-24 closed by remote host.

I also mointored the output of dmesg | grep -i drm
The last output I was able to save on disk is this:
