JohnRH's questions

Have spent a lot of time on this one one but can't find an answer here.

Ubuntu 14.10 clean install. AMD A10-7700K APU with Radeon(TM) R7 Graphics x4.

1) Started with the xserver open-source wrapper and all seemed ok.

2) Installed BOINC but 'No useable GPUs found' in Event Log.

3) Reinstalled BOINC with boinc-amd-opencl but same result, except that it installed AMD graphics fglrx-updates.

4) Downloaded & installed latest Calalyst from AMD and that didn't work at all, wouldn't boot past the mauve screen!

5) Reverted back to setup above. But still no OpenCL for BOINC.

6) In case this was only a 'BOINC' glitch, I went to their website. Found some old stuff about KAVERI support, which didn't solve it.

7) Another program with this problem, darktable, also can't find OpenCL.

A snag is that there doesn't seem to a utility in Ubuntu that tells me clearly whether OpenCL is functional or not.

So conclusion? Ubuntu 14.10 + fglrx 14.201 + AMD A10-7700K = no OpenCL.

True? Hopefully someone out there knows the answer.

Have just done a hardware upgrade with existing Ubuntu 14.04, including an AMD APU A10-7700K. But I found that the 3 offerings in Additional Drivers didn't work properly so I couldn't start the Control Centre, and couldn’t get OpenCL. So I installed the Catalyst 14.4 package from AMD (which wasn't too hard!), but now I get a black border on my screen. My monitor is a Samsung 22" LED S22D300. Otherwise all seems OK. I found some instructions at wiki.cchtml.com but didn't work. Playing with the settings in Control Centre didn't work either. Anyone else have this problem? How to fix it?

Have been running BOINC with a GeForce GTS450 GPU for some time under earlier Ubuntu versions and and has always run OpenCL flawlessly. I've just done an online upgrade to 14.04 and now BOINC log tells me "...needs OpenCL but GPU doesn't support it". Same result with darktable. Driver version is 304.117. Anyone know the reason why this should suddenly happen, or how it can be fixed? Just to be clear, the upgrade is all I've done, I haven't changed anything else.
