Both GPUs are used by default. If you attach your /etc/X11/xorg.conf and /var/log/gpu-manager.log we can see what's going on.

In any case I wouldn't expect to find any options in the AMD panel to switch between the two GPUs. That's only available on Intel+AMD systems.

[Alberto Milone (albertomilone)]

both GPUs are enabled as I said. I think this is by design.

[Alberto Milone (albertomilone)]

apparently there should also be an option to switch between cards on AMD+AMD systems.

[hugotian (hugo-tian)]

Can't duplicate.

Are you sure you turn on the PX mode in the system BIOS?

[Yang Kun (YK) (dayangkuncn)]

@yung shen, could you please help to check if there is a "PX mode" in the system BIOS and if it's turned on ?

thanks
-YK

[Yung Shen (kaxing)]

@hugo-tain and @dayangkuncn

I did not see the "PX mode" in BIOS settings, but I supposed it's the same option to "Switchable Graphics", which is being enabled but still not able to switch graphic cards.

BIOS version: 68CPE Ver. F.21

[Chih-Hsyuan Ho (chih)]

@Yung, if the "Switchable Graphics" is enabled in BIOS, the PX mode that AMD referred to should already be there. And according to AMD team, switchable graphics in AMD Richland should just work.

Can you help provide more info by going through the following commands:

aticonfig --lsa

Is the xorg.conf existent? If not, can you run the following command to create one?

sudo amdconfig --initial --force --adapter=all

Afterwards, please reboot the system and retest this issue. Thank you.

[hugotian (hugo-tian)]

Hi Chih-Hsyuan, you also can try to give the log file to us.

[Chih-Hsyuan Ho (chih)]

@Hugo, all the affected units happened to be called back by ODM at this moment and we will try to collect the logs as requested once we have them back. Thanks.

in the attachment lp1315285.tar.gz
there is
aticonfig-lsa.log (suggested by the comment #12)
gpu-manager.log (suggested by the comment #5)
lspci-nn.log
xorg.conf (suggested by the comment #5)

Has the same issue:

Please refer to the attachment lp1315285_201403-14879.tar.gz for more details.

[Chih-Hsyuan Ho (chih)]

According to AMD engineering, the A+A platforms based on Mullings and Beema chipsets do NOT support switchable graphics. It is made clear that in their GUI configuration tool (AMDCCCLE), no such option exists for such platforms.

[Chih-Hsyuan Ho (chih)]

And in other AMD A+A platforms such as [AMD Richland + Mars], which this issue was originally reported against, switchable graphics works with the latter Catalyst driver (14.502, earlier drivers may also work but not verified) after disabling gpumanager so that the X configuration is not further overwritten by it.

[Alberto Milone (albertomilone)]

@Chih-Hsyuan Ho: can we get a working xorg.conf from those platforms, please? This way I can make sure that gpu-manager does the right thing, if that is the problem

[Chih-Hsyuan Ho (chih)]

The working xorg.conf is attached for your reference.
