nVidia has made them officially “stable”.

They fix quite a fair amount of problems:

1. -With Powermizer active, the speed of the video card wouldn’t get adjusted when playing a video with VDPAU, resulting in poor playback quality in some cases.
   

2. -No need for disabling Composite in X configuration file xorg.conf to prevent tearing
   

MythTV, MythPlugins and MPlayer must be updated as they now depend on nvidia-libvdpau-185 which superseed nvidia-libvdpau-180.

How to upgrade:

Start synaptic

Click on “Reload”

Click on “Mark All Upgrades”

This will prompt you that nvidia-glx-180 and nvidia-libvdpau-180 will be uninstalled. That’s okay.

Do not click Apply yet.

Mark to install nvidia-glx-185

Apply.

If you don’t care about rebooting your machine:

-> reboot your machine.

If you do:

sudo /etc/init.d/gdm stop

sudo rmmod nvidia

sudo modprobe nvidia

sudo /etc/init.d/gdm start
