Detect What Processes are Using the GPU on Linux
 
I have been bitcoin mining on my laptop just for fun and I have been using a miner called cgminer. When I start up cgminer it tells me that my GPU couldn't be enabled and it is likely because some other process is using the GPU. The exact message is below.

Code:
[2011-11-14 17:01:53] Failed to init GPU thread 1, disabling device 0
[2011-11-14 17:01:53] Restarting the GPU from the menu is unlikely to fix this.
[2011-11-14 17:01:53] Try stopping other applications using the GPU like afterburner.
[2011-11-14 17:01:53] Then restart cgminer.
Press enter to continue:
I looked through my running processes and I don't think any of them are using the GPU but I would like to be sure. I can't figure out how to figure out what processes are accessing the GPU.

I asked this on the bitcointalk.org form but no one replied so I figured since it really has noting to do with bitcoin specifically I could get some good answers here.

Before going too far with this, how many graphic cards do you have installed on your system? Are you using the graphic card for your primary display, that you want to use for mining bitcoins? If so, that may be your issue - Try using your motherboards integrated graphics card, if it has one. Also, what GPU make and model do you have?

Cheers,

Josh

I have only one GPU but I am not running a desktop. I am running it from the command line.

lspci -v give me this (and more)

I hope that is enough information.
Thanks for your help.
