Comment 21 for bug 365885

I did it that way, however Brandon just added yesterday the nvidia driver 190 to his repo (leaked pre-beta version) so it may conflict with some libraries, in special libxine-vdpau since he is compiling for vdpau testing purposes, so i would better use synaptic or aptitude to install the 185 drivers and libraries manually instead of Hardware Drivers manager.

However might give it a try with the drivers manager, if you find any problems with package versions use a package manager to correct them.
