Tried that before, is not working unfortunatelly ...

Code:
sudo fglrxinfo

gives me this

Code:
display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 5800 Series
OpenGL version string: 4.2.12217 Compatibility Profile Context 12.104

so I assume a
Code:
export DISPLAY=:0.0
is required? Or do I need
Code:
export DISPLAY=:0
?

Neither ist working ...

Here is everything in one piece:
Code:
xxx@Eibe:/opt/poclbm$ export DISPLAY=:0
xxx@Eibe:/opt/poclbm$ sudo python poclbm.py

WARNING: no adl3 module found (github.com/mjmvisser/adl3), temperature control is disabled


OpenCL devices:

[0] Cypress
[1] Intel(R) Core(TM)2 Duo CPU     E6750  @ 2.66GHz

No devices specified, using all GPU devices


At least one server is required

xxx@Eibe:/opt/poclbm$

That's the important error message, you didn't provide any mining pool server address.

A possible workarround for people that have hardware error with the driver 13.4 and can't downgrade the driver ... :

The BFI_INT optimisation look like to be problematic on that driver version, more informations :

https://bitcointalk.org/index.php?topic=221041.new#new

EDIT : i think it should be a good idea to define or not BFI_INT depending on the version of the driver also and not just only the plateform name (aka Jupiter for my 5770)

Hello fellow miners.

I use poclbm without any major problems, but every now and then I will get an error message:
Code:
Verification failed, check hardware! (<hwID>, <32bit hex value>)

The general advice is to check one's hardware and I concur, but I want to look at it from a different angle.

My question is on the mathematical side. What exactly is tested to perform this verification?
I haven't seen it described anywhere.

The miner check the result of the opencl kernel by doing the double sha calculation with the nonce just found by the kernel.

Makes sense.
Thank you.
