Unity display corrupted on login or switch user

[tap]

I have a new install of 15.04. I am using lightdm with a unity desktop (default). I have two users on my system. Often when I log in or switch user unity or lightdm (I don't know enough to understand which one) will freeze on a corrupted display. The launcher icons and the launcher will be overwritten with some pseudo-random pattern. the bar across the top of the display will also be corrupted. Sometimes the display has both my desktop and the unity-login greeter mixed. I usually can't type or do alt-f2 for several seconds. At some point (usually several seconds later) the display will appear to "reset," sometimes once, sometimes several times and eventually will settle on an uncorrupted, usable screen. If I switch user 10 times this will happen on 8 of them.

Corrupted graphics suggest this is an X server problem.

tap, could you please run the following command from a terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1497621

Please ensure you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

tap, as per http://www.dell.com/support/home/us/en/19/product-support/product/precision-t7400/drivers an update to your computer's buggy and outdated BIOS is available (A11). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Chris,

Here is what I have done (prior to receiving your most recent email) ... I
tried upgrading the nvidia drivers but could not because I had a very old
card. I purchased a newer one (GeForce GTX 660), installed it, rebooted,
upgraded the nvidia drivers to 346.96, rebooted and found the problem to be
gone. Is there anything else you would like me to run at this point that
might be helpful?

-Todd
