After updating from 13.04 to 13.10 many of 3D unity stuff has stopped working,

I am suing Samsung Series 3 (NP350V5X) Laptop which has Switchable Intel and AMD Radeon HD 7670M GFX.

  1. xserver-xorg-video-ati does works but NO 3D support and graphics are very low. [I am currently using this]
  2. fglrx & fglrx-updates shows blank screen after Login.
  3. Intel Graphic Install doesn't work either (dependency error)

Output of $ sudo lshw -c video

Similarly $ /usr/lib/nux/unity_support_test -p

Shows no 3D support.

Can anyone please guide how to make things working again.

Update: Issue fixed now, after updating to latest Ubuntu Binary for ATI. (https://help.ubuntu.com/community/BinaryDriverHowto/ATI)

Output of $ /usr/lib/nux/unity_support_test -p is,

I have the same issue. Using lshw

  *-display:0

I tried using mesa 10.0 with no impact.

After installing the proprietary fglrx driver you have to generate a fresh xorg.conf BEFORE REBOOTING! you have to run:

$sudo aticonfig --initial

If you already installed the drivers and rebooted getting a blank screen after login, press CTRL+ALT+F1, login, run the command from that console and reboot.

I recommend you read the full ubuntu help wiki on the subject:

BinaryDriverHowto/ATI

Hope that helps!
