Comment 5 for bug 430865

"But messing up the display when building (or more precisely, when triggering the module build) seems kind of weird..."
it happens after the build fail, the X server does this mess when there is no nvidia module and it is written nvidia in xorg.conf

This problem is occurring everytime there is a new rt kernel update.
dkms tries to build module, it fails, because nvidia driver is not made for this kernel as it is older
