Tom's Hardware Ask Me Anything – AMD - November 6

[Dirk Broer]

All was well till last Thursday, when it appeared my Ubuntu box had spontaniously re-booted.
It would not recognize the GPUs (and that's three of them) in Boinc since, nor would it start up with launch bar or menu bar when run with fglrx drivers (either 13.4 or 13.8)
The open source drivers have no missing bars, but you can't crunch with them.

I had my earlier Lubuntu problems solved by re-installing 13.10 with a newly burned DVD, and BOINC 7.2.7 is running fine with Catalyst 13.4 on the Lubuntu box, only a bit sluggish. I even returned valid MilkyWay WUs done on the A10-5700! But what makes people at Canonical decide to use experimental (7.2.7) BOINC versions?

I just burned a new Ubuntu 13.10 disk to try and repair the installation on the Ubuntu-box and so far, so good. The Ubuntu box is happily crunching on the fglrx drivers that came with 13.10 and started using the HD 6550D and the better (2 GB) HD 6670 without even a cc_config.xml edit!
Almost like the time I installed my GTX 630 alongside the A8-3820 -under Windows- and got PhysX for the HD 6650D too.
Looks like the OS-es do not 'see' the AMD IGP of the APU, at least not as being equal to a discrete graphics card. In the case of the HD 7660D a most remarkable feat, as it outperforms a HD 6670.
