wave motion on laptop screen using ubuntu 10.04


I installed 8.04 ubuntu on my Dell Inspiron 9400 laptop. I upgraded it to 10.04. My screen now has a terrible wave on it when I scroll up or down. What can I do to correct this problem? Thank you

Terrible wave.

Open up terminal and post the output of -

lspci -a

Does Ubuntu ask you to install any non free drivers?

Hello, all I get is:

-v Be verbose
-n Show numeric ID's
-nn Show both textual and numeric ID's (names & numbers)
-b Bus-centric view (PCI addresses and IRQ's instead of those seen by the CPU)
-x Show hex-dump of the standard portion of config space
-xxx Show hex-dump of the whole config space (dangerous; root only)
-xxxx Show hex-dump of the 4096-byte extended config space (root only)
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] Show only devices in selected slots
-d [<vendor>]:[<device>] Show only selected devices
-t Show bus tree
-m Produce machine-readable output
-i <file> Use specified ID database instead of /usr/share/misc/pci.ids.gz
-D Always show domain numbers
-M Enable `bus mapping' mode (dangerous; root only)
-P <dir> Use specified directory instead of /proc/bus/pci
-H <mode> Use direct hardware access (<mode> = 1 or 2)
-F <file> Read configuration data from given file
-G Enable PCI access debugging
