comment Opencl application does not recognize GPU till user physically ( and not remote) logs in to machine
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...

comment Disk going from near empty to full in one day no obvious explanation: how to diagnose
Add to that the Strange Ubuntu practice of automounting a drive at /media/hari/FreeAgent GoFlex Drive1 and calling the nautlius menu and the drive name without the 1 suffix. So I was all confused since I had a /media/FreeAgent GoFlex Drive and a ubuntu created /media/hari/FreeAgent GoFlex Drive1 which was called "FreeAgent GoFlex Drive". Also I always failed to read the first few lines of my du -h1 -h on /media which clearly said where 114GB was "missing"

comment Disk going from near empty to full in one day no obvious explanation: how to diagnose
I think I am close to resolving this. I had created a permanent mount point in media for my external disk "FreeAgent GoFlex Drive" . I also had a crontab entry that was intended to backup to that external disk. At some point the external disk mount point changed to "FreeAgent GoFlex Drive1" and rsync created a mirror of my data on confusingly called /media/FreeAgent GoFlex Drive. I always failed to read the du output correctly It clearly said "du: cannot read directory ‘./hari/FreeAgent GoFlex Drive’: Permission denied".

comment Disk going from near empty to full in one day no obvious explanation: how to diagnose
Thanks for your answer. When I go to /media I see a very strange behavior when I run "df -d1 -h " I get output: . 24K ./hari 4.0K ./cnstnewest 114G . So it seems that there are 114G of files in media without any external disks mounted. lsof +L1 gives very few files : all owned by chrome and gnome terminal.

comment Disk going from near empty to full in one day no obvious explanation: how to diagnose
The additional files are not due to an expansion of /var /tmp /home . Some other part of my filesystem is building up and taking up space. I am scared some indexer is working extra hard and storing its data somewhere in a manner that is hidden from du ( /home remains constant at 91GB ..but disk space df went from 13GB free to 1GB free again)

I unmounted and removed all mount commands from /etc/fstab etc and then re-booted --the space does not return. I will change the mount points to /media. I now have 6.8GB free..hope this stays the same tommorrow. The previous few days the space remaining "disappeared" overnight.

comment Gnome3 Terminal restores previous window size on focus loss
The answer does not specify this so I thought I would clarify. For some reason setting a Custom starting width and height in the Default profile suddenly gives the resulting terminal an ability to remember its dragged final size--having it as blank causes it to snap back

comment Why do pages not load in any browser after updating Ubuntu 12.04?
I have the same problem and strangely in Chome clicking CTRL-SHift_Delete makes the page chrome://settings/clearBowserData show up and continuously display the "loading" message like every other page with chrome..
