[Bug 987949] Re: Ubuntu 12.04 - Severe Graphics Regression on Hybrid System with Integrated Intel HD300 graphics and NVIdia OPTIMUS

[Sircu Ion]

I have the same issue with an Acer 4830g laptop. It is using hybrid
graphics as well with an nvidia card. When i was trying to install
Bumblebee, one of the steps i did was to purge the installed nvidia
drivers. After that Ubuntu shifted to Unity 3d.

After however building the latest nvidia driver from source and
installing and enabling it in bumblebee i am back to Unity 2d and it
doesn't change even if i specifically select it at logon.

Is there a workaround to force Ubuntu to use the integrated graphics
until using the bumblebee "optirun"?

Title:
  Ubuntu 12.04 - Severe Graphics Regression on Hybrid System with
  Integrated Intel HD300 graphics and NVIdia OPTIMUS

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  I just did a full Install of Ubuntu 12.04 daily-live. Unity defaults
  to Unity-2d, with many issues therein (tearing, etc.)

  It is the first time I fully install 12.04, but I have been regularly
  trying daily-builts from live-usb-stick... Never had issues, if
  anything everything seamed snappier and faster than 11.10.

  I have a hybrid system, and to date I have always been using by
  default the grapbhic drivers for my integrated  i7 graphics card. I
  now see it defaults to the Nouveau drivers, that must be the cause of
  the regression.

  TEMPORARY FIX: Removing packages "nvidia-current" and "nvidia-
  settings" and restarting your system should do the job. Hope this gets
  fixed soon...
