How to mine in Ubuntu? How do you mine in Ubuntu 11.04? Are there any GUI miners like poclbm-gui for Ubuntu?
GUIminer can be run on linux, although the process (described in the official thread) is somewhat complicated.  To summarise that post, you will need to:


Get the source code from GitHub:

git clone https://github.com/Kiv/poclbm
Install OpenCL drivers and PyOpenCL.
Install wxPython:

sudo apt-get install python-wxtools
Run guiminer.py:

python guiminer.py


Note that (at least to use the poclbm backend) no compiling is necessary since GUIminer is written in python.  But I can still understand if you find that process a little daunting, since I don't know your level of technological familiarity with these sorts of tasks.
