Changing Drivers (nVidia)

I was wondering on how to downgrade nVidia drivers on Ubuntu because the new 180.22 drivers are giving me very high temps (70C on idle compared to ~50-60C before).

Also, are the drivers from LV2G good for Ubuntu? Thanks!

 

Downgrades are kinda messy. If you're fine with doing a little fiddling with the internals, you could edit Xorg.conf to force nVidia into its lowest power setting.

NOTE: Be VERY CAREFUL when you do this. Especially if it's your first time.

Code:

$ sudo gedit /etc/X11/xorg.conf

Then add the following line to the "Device" section:

Code:

Option         "RegistryDWords" "PowerMizerLevel=0x3"

It should end up looking something like this. Just add the line in bold somewhere, and don't change anything else.

Code:

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
    VendorName     "nVidia Corporation"
    BoardName      "GeForce 9600M GT"
    Option         "NoLogo" "True"
    Option         "TripleBuffer" "True"
    Option         "RenderAccel" "True"
    Option         "BackingStore" "False"
    Option         "DamageEvents" "True"
    Option         "DPMS" "True"
    Option         "AddARGBGLXVisuals" "True"
    Option         "ConnectedMonitor" "DFP"
    Option         "XaaNoOffscreenPixmaps"
   #Option         "RegistryDWords" "PerfLevelSrc=0x3333" #fully adaptive
    Option         "OnDemandVBlankInterrupts" "True"
    [B]Option         "RegistryDWords" "PowerMizerLevel=0x3"[/B] #low power
   #Option         "RegistryDWords" "PowerMizerLevel=0x2" #med power
   #Option         "RegistryDWords" "PowerMizerLevel=0x1" #high power
EndSection

 

Hey, thanks for the quick reply!

I have been monitoring my clocks and they have been at the lowest settings (169/100) vs. stock (475/400), so I think powermizer is doing its job.

I also had this problem in XP, the idle temps were really high whenever using any 18x.xx drivers.
