Yeah i tried killing the pid.  doesn't work. 

So I get to restart and re-write my /etc/network/interfaces file everytime.

Is there any way to get my USB stick to write that file?  sudo sync doesn't write it to the usb stick.

Yup thats all it takes Smiley But the only way to get rid of that 99% most of the time is a coldreboot

Yeah I had one machine that GPU 1 and 3 reported SICK so I was able to just raise those clocks a little.

You could do a screen -r and you will see cgminer running.. usually you will see the gpu that has no hashes submitted or speed. It will look dead or be dead. Maybe even sick.

Is there a way to tell which GPU hung?  I looked through DMESG and couldn't tell which one it was.

I would rather just change the settings on 1 GPU then change all 5.

When your at Xorg 99% that means a GPU Hung.. If you downclock and undervolt it will take a bit of work to find the sweet spot.

I should add that all my miners have run rock solid for 2 months straight before I saw this Xorg problem and it only started after I downclocked my 5870's to 800/150/.959

I am putting them up to 825/300/1.000 and will see if that fixes the problem.

It must be it since that is the only change I made besides switching them all to 220V which would make no difference.

I have a couple of machines that will mine for a day or so then the cgminer screen will lock up.

I ssh into the machine and cgminer was killed and Xorg is using 99% of the cpu.

I have seen this happen on multiple machines.

All running 11.04 Ubuntu from USB stick.  Cgminer.

Anyone had a similar problem and found a solution?
