@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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1315285 Title: [AMD Richland + Mars] Unable to switch graphics Status in “fglrx-installer” package in Ubuntu: Triaged Bug description: Unable to switch in between APU and Discrete GPU.
