[ppa:oibaf/graphics-drivers] Held broken packages (libgbm1) from ppa:oibaf/graphics-drivers

[hectorsales]

 Dear Maintainer,

I have upgrade from ubuntu 14.04.1 to 14.04.2 (LTS Enablement Stacks) whith:

$ sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

After, i try enable ppa:oibaf/graphics-drivers ( bleeding-edge X.Org/Mesa) and i have a issue with the file: " libgbm1":

$ sudo apt-get install libgbm1 -s

I also have installed Ubuntu 14.04.2 in virtualbox - fresh install- to see if there was any error on making the upgrade( LTS Enablement Stacks) on the host machine ... but I have the same error in the virtualized machine (fresh install ubuntu 14.04.2) after enable ppa:oibaf/graphics-drivers ....

i think there're another thread similar (xorg-edgers):

Hi, my packages are not compatible with LTS enablement stack. There is also not much point in mixing them, just use LTSES or oibaf ones.
