I've installed the Catalyst driver (fglrx-14.501.1003) using the Recommended mode and custom build mode in the generic Linux 32/64-bit installer on Ubuntu 14.04.1. The fglrx driver loads at boot, but clinfo only reports the CPU as present. Any suggestions?

Solved! Go to Solution.
Perhaps it is because this is a headless system, but the solution was to uninstall the "fglrx" package and install just the "Non-X Support" Ubuntu 64-bit fglrx-core DEB package from the Catalyst driver download page: http://support.amd.com/en-us/download/desktop?os=Ubuntu+x86+64
Note: This could mean that either my custom build from the generic Linux 32/64-bit installer was bad or that a headless system simply should not have the "fglrx" ( Video Driver For Graphics Accelerators ) package installed. I will leave that determination up to AMD as there is sufficient information in this thread to reconstitute my environment and test the problem. Cheers.
FYI this system is headless. Does the Catalyst driver still have issues with headless systems? Lightdm is running and X is on display 0.
I am not sure whether this can help, but I also came across this case yesterday when I tried to install SDK 3.0 with Omega driver. I can only find CPU at first. No matter how I reinstall the SDK or the driver again and again.
I finally find that this is because I didn't uninstall the previous driver completely (which means, I though I have uninstalled because I already used some commands to do that, but actually I should use apt-get purge command to remove them because I install them with apt-get install). After that, I reinstall the driver, then SDK. Everything is OK.
My Ubuntu is 14.10. FYI.
Can you list which packages you purged? I've purged fglrx, fglrx-core, fglrx-amdcccle, and fglrx-dev.
Catalyst driver still does have issues with headless systems till 14.9. I haven't got the chance to test 14.12 yet. Have you tried the purge then reinstall method @acekiller mentioned below?
My complaint in the other thread was limited to get APP SDK's driver to work on CPUs. I don't think you technically need APP SDK for GPUs to work.
Hmmm. I did reply to the email, but I don't see my response here :-(
I have pretty much the same setup with you. Ubuntu 14.04, omega catalyst, SDK 2.9-1. My card is a bit different, curacao R9 270. I can see both CPU and GPU in clinfo. What is your SDK?
We also have the same logs. The only difference in line 16 of your dmesg: fglrx enable the IOMMUv2 support, which i don't have and is not critical.
Plz email me your strace to diff it with mine, i cannot go through it over the web :-(
I see 2 possible obvious issues:
1) Reinstall catalyst then SDK. Careful when removing old catalyst drivers, you don't want to end up with no video (you may have to un-blacklist radeon open source driver).
2) Your SDK doesn't support your card.
If those don't fix it, we might need to delve deeper :-(
1. I've purged the fglrx-* packages using "apt-get purge" and re-installed from a clean slate.
2. I'm using V 3.0 of the SDK. This is a Kaveri APU and should be well supported by the SDK.
