I have posted my experience with updating from 9.04 to 9.10. The
resulting UI is just about unusable.
I am using the NVidia Version 96 driver.
I also observed that the icons changed in appearance (for example the
wireless icon or the help icon are 'washed' out).
I discovered that System->Preferences->Startup Applications had a large
number of applications checked. I have removed 'Blue Tooth, and
Evaluation Alarm' and unchecked most of the rest except Network Manager,
PolicyKit Authentication, Print Queue Applet, Update Notifier, and
Volume Control.The GNOME Settings Daemon and GNOME Settings Daemon
Helper seemed to have helped as _now the icons are drawn properly and
the UI is behaving better._
My initial observations
1. Click on icon does not cancel and mouse drags the icon image around.
2. Highlighting while typing - if you move mouse while typing the text
in some nearby area is highlighted.
3. Scrollbar is 'sticky' and scrolls the page while mouse is move in the
4. Click on close or links takes many tries.
Seems like my messages to the forum 'Installation & Upgrades' are
ignored. My last posting informs the group that I will be going back to
Good luck with your quest
