<pre>I have hybrid graphics card setup (AMD 6470M / Intel HD 3000 sandy bridge). I
followed <a href="http://www.phoronix.com/scan.php?page=news_item&px=MTQyNDE">http://www.phoronix.com/scan.php?page=news_item&px=MTQyNDE</a> 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
<a href="http://people.freedesktop.org/~agd5f/radeon_ucode/">http://people.freedesktop.org/~agd5f/radeon_ucode/</a>. 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
(<a href="https://help.ubuntu.com/community/HybridGraphics">https://help.ubuntu.com/community/HybridGraphics</a>). 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 !!
