This post relates to a Toshiba Satellite Laptop, dual booting WinXP and Kubuntu, where a full package update to Kubuntu ver. 9 has caused some display problems rendering the linux desktop essentially unusable. I recently updated from a fully operational Kubuntu 9.04 desktop environment to 9.10 via a complete package update. Here are my current boot options.

Kubuntu is now is a mess. If I boot the 2.6.31-15 partition, the active window display has been resized to enormous proportions; for example, here is the KDE wallet login; this is what mouseover text looks like; and this is the right click dialog.

If I click on an active window, I get this, so I'm really at a loss to figure out how to even begin approaching a fix.

If I boot the 2.6.28-11 partition, in addition to the other problems, the touchpad no longer responds, so any proposed fix there must be keyboard based.

Windows still boots up fine and works as good as it ever does.

Can I roll back to 9.04?
If not, I'm looking to fix the display and revitalize the touchpad.
I know I can nuke the HD and start over, but that is not an optimal resolution.
Any help solving these problems is greatly appreciated.
