Yes, this bug is still there with Trusty Tahr (I'm on Ubuntu 14.04.1
right now). I can confirm that "sudo /etc/init.d/boinc-client restart"
works, and GPU is recognised after that. However, while GPU is
recognised, now the problem is, "App version needs OpenCL, but GPU
doesn't support it". I installed the boinc-amd-opencl package (and its
fglrx proprietary drivers) through Synaptic, but it's not working. I'm
using BOINC 7.2.42 and my CPU (which works fine) is an AMD Fusion
Trinity A10-4600M, and my GPU is AMD Radeon HD 7660G+7670M.

Of course, ultimately, this isn't the fault of Linux/FOSS developers;
the real problem here is crappy GPU drivers; all this would work so much
better if AMD fully open sourced their GPU drivers. Anyway, when
installing the official AMD Catalyst drivers from AMD's website, the GPU
works fine in BOINC. For some reason, the proprietary AMD GPU drivers in
Synaptic are outdated or something, and they don't recognise my GPU
properly, but installing the latest Catalyst from AMD's website, solves
