Hi all, I continue to get freezing even after manually upgrading
from the default ubuntu 180.44 to the 185.18.14 nvidia driver .

I have:

- Jaunty 32-bit version running on a Dell Precision 4400 laptop
- Quadro FX 770M (514 MB)
- running compiz

Compiz graphical maneuvers (workspace switching, cube rotate
, etc.) work well initially. Then the screen freezes in the middle of
an effect, losing the mouse and keyboard. I'm usually able to
recover after 30 seconds, but often I'm left with remnants of
window images for a background, and some icons are missing
from the Firefox toolbar. And on more rare occasions, the X server
crashes and sends me back to the login screen.

Here are parts of the Xorg.0.log file:

. . .
(II) NVIDIA(0): Initialized GPU GART.
(II) NVIDIA(0): Initialized GPU GART.
(WW) NVIDIA(0): The NVIDIA X driver has encountered too many errors. Falling
(WW) NVIDIA(0): back to write-back cached memory.
(II) NVIDIA(0): Initialized GPU GART.
(II) NVIDIA(0): Initialized GPU GART.
. . .

I've attached the full log. But note that
the problem starts near the spot where you see
the above text.

I'm considering downgrading the nvidia driver.
Appreciate any insight.
