This is a part of the massive dump of problems I'm encountering with my Lenovo Y460 and Ubuntu.
Problem: ATI PowerXpress doesn't really work.
- Doesn't work as I have to use the open source driver with hacks.
- Turned off ATI card at boot
- Details on how I accomplished that: http://ubuntuforums.org/showthread.php?p=10955831#post10955831
- Installing the ATI drivers results in a failure of the intel drivers to work with Ubuntu Class (all animations have to turned off).
Anyway to fix this problem to allow switchable graphics to work?
The problem above has been fixed by FGLRX (Catalyst 11.6) is it compatible with kernel 2.6.39?
However, there's another issue. If I connect my secondary monitor (VGA 17'') while using the Intel driver, I would not be able to use that screen as there's flickering and tearing, making the screen blurry and usable.
Here's the fglrxinfo:
$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile GEM 20100330 DEVELOPMENT
OpenGL version string: 1.4 (2.1 Mesa 7.10.2)
Any fixes for that?
Potential related bug report on launchpad: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/750259 However I can't confirm because the video showing that is much more dramatic than what I have, mine are tiny flickering that won't be captured by video cameras as I've tried, but enough to make it blurry for humans.
