Comment 2 for bug 653714

I re-installed 10.04 on a different disk, and found that a fresh install used the nouveau driver as well and that it too exhibited the screen garbage problem. However, with 10.04, selecting "hardware drivers" offers the Nvidia accelerated graphics driver (version 96), which, once activated, works correctly with no garbage.

So, the following driver works OK:

johnn@johnn-laptop:~$ lsmod | grep -i nv
nvidia 4701243 32
agpgart 31724 2 nvidia,intel_agp
johnn@johnn-laptop:~$
johnn@johnn-laptop:~$ dpkg --get-selections | grep -i nvidia
nvidia-173-modaliases install
nvidia-96 install
nvidia-96-modaliases install
nvidia-common install
nvidia-current-modaliases install
nvidia-settings install

Description: NVIDIA binary Xorg driver, kernel module and VDPAU library
 The binary driver provide optimized hardware acceleration of OpenGL
 applications via a direct-rendering X Server. AGP, PCIe, SLI, TV-out
 and flat panel displays are also supported.
 .
 This package also includes the source for building the kernel module
 required by the Xorg driver.
 .
 GPUs ranging from GeForce series 2 (except for GeForce2 GTS/GeForce2 Pro,
 GeForce2 Ti and GeForce2 Ultra) to Geforce series 7 are supported.
 .
 See /usr/share/doc/nvidia-96/README.txt.gz for a complete list
 of supported GPUs and PCIIDs

And the following drivers DO NOT work correctly on this hardware:

johnn@johnn-laptop:~$ dpkg --get-selections | grep -i nouv

Description: X.Org X server -- Nouveau display driver (experimental)
 This driver for the X.Org X server (see xserver-xorg for a further description)
 provides support for NVIDIA Riva, TNT, GeForce, and Quadro cards.
 .
 Although the nouveau project aims to provide full 3D support it is not yet
 complete, and these packages do not include any 3D support.
 Users requiring 3D support should use the non-free "nvidia" driver.
 .
 This package is built from the FreeDesktop.org xf86-video-nouveau driver.
