[Nvidia Quadro FX 3500] lockups - Ubuntu 14.04

[Michael Sabino]

Hi,

I am having a similar issue to the bug report here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310762 ; Lockups that can sometimes be resolved by hitting Alt+F1 and going to the console, then hitting Alt+F7 to go back to the gui. Sometimes the screen should've been updated to the logon screen after the screensaver kicks in and I move the mouse, but instead I occasionally see garbage, then have to hit Alt+F1, and Alt+F7, and it will bring me to a black screen with a mouse cursor that if I type my password in will bring me to the desktop (although sometimes that doesn't work). It apparently should be displaying the logon screen, but my actual screen never gets updated.

Hardware Configuration:
*Quadro FX 3500 on a Dell Precision 390 desktop
*DVI to HDMI cable
*Ubuntu 14.04 (Trusty)
