Is this the case for the Linux Legacy Catalyst Driver 13.1 ( AMD Catalyst™ Driver for AMD Radeon™ HD 4000, HD 3000 and HD 2000 Series ) as well ?
I've just installed it on Ubuntu 12.04 LTS (with a few patches so that the kernel module will compile against kernel 3.6) and when using OpenCL no GPU device can be be found (but a CPU device can be found).
If it is the case that the OpenCL drivers were removed how do you know? I can't find release notes for this particular driver and libOpenCL.so is shipped with this driver.
