Title:
16 Bit colours / Banding on Intel HD4000
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Released
Bug description:
On my Asus Zenbook UX32V (Intel HD4000) I experience 16bit
colours/banding on the internal LCD panel. The external monitor works
fine (no banding is to be seen).
This happens on at least:
linux-image-3.5.0-19-generic
linux-image-3.5.0-18-generic
linux-image-3.5.0-17-generic
and not on
linux-image-3.5.0-10-generic
Others were not tested as I reinstalled my system.
I experience the same behaviour when using the xorg-edgers repository.
This issue might be related to
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1085166 in some
way as they started occuring at the same time (This sounds vague, and
it indeed is as I only noticed after doing some more kernel updates,
so I am not sure where this issue came up)
