Comment 17 for bug 1177433

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 For some reason, the proprietary AMD GPU drivers in Synaptic are outdated or something, and they don't recognise my GPU properly, but installing the latest Catalyst from AMD's website, solves it.
