I have hybrid graphics card setup (AMD 6470M / Intel HD 3000 sandy bridge). I followed http://www.phoronix.com/scan.php?page=news_item&px=MTQyNDE and installed 3.11 kernel on ubuntu 13.10 daily. I also installed mesa 9.2 using xorg-edgers ppa. When I tried to boot using radeon.dpm=1, it had shown a message about missing driver (CAICOS), therefore I replaced all drivers in /lib/firmware/radeon with the one downloaded from http://people.freedesktop.org/~agd5f/radeon_ucode/. I ran "update-initramfs -u", after which the message had gone. This time when I tried to boot using radeon.dpm=1 and it froze. I even tried to turn ON AMD graphics card using vgaswitcheroo (https://help.ubuntu.com/community/HybridGraphics). When I logout, and tried to login it sometimes showed black screen or sometimes froze. I had seen the development page (I don't remember where), and the hybrid graphics card switching was not fully fixed. Is this still the problem?
