Description xpressrazor 2013-08-08 13:11:07 UTC 
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?

Thanks !!

Is this still an issue with a newer kernel?

xpressrazor@gmail.com, Ubuntu 13.10 reached EOL on July 17, 2014. For more on this, please see https://wiki.ubuntu.com/Releases.

If this is reproducible with a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
