This does not seem to solve the problem. So far only the autologin user has the effect of exposing the gpu to remote shell opencl processes...although I suspect that there is something weird in the opencl code that detects the available devices. I dont see too much of a run time difference whether or not the opencl code "sees" the GPU, so I suspect it just pretends to not "see" it but runs just as fast.

Hi I tried your approach, however I ran into a slight snag. The $DISPLAY environment variable in my case is blank and the first command fails to extract the auth-file.

comment Enter SSH passphrase once
So to clarify: With this "fix" you will only not have to type in the passphrase in that terminal again. The moment you open a new terminal - you will have to give the passphrase again.

comment Disk going from near empty to full in one day no obvious explanation: how to diagnose
Thanks Steve. I observed exactly what you described. Reboots were not freeing up any space. In some cases a tune2fs - m0 on the drive freed up some space. In the end I systematically went from directory to directory as you recommended and a combination of du -sc * | sort n and "du -d1 -h " helped me diagnose a directory in /media whose name corresponded to my external disk name "Freegent GoFlex Drive" which I mistook for my external disk. It had 144 GB of my "free" space because rsync created it due to a crontab job that ran everynight at 3.00 am. I also missed seeing it in my df runs

I too thought about this a bit and did learn from the sort approach that Steve Dee answer below as with Rmanos comment above. If only I could split the bounty or accept multiple answers. People like you are rare...
