Hi Lucky, The Dell Optiplex I was experiencing this on is only has built-in Intel GMA950 graphics so if it definitely is a graphics driver issue then it might not be something limited exclusively to Nvidia drivers.
Gabriel Alonso (Post #6) mentiones having this issue with a Dell E6400. These laptops have built-in Intel graphics but can also come fitted with an Nvidia Quadro so it'd be very interesting to see what card is fitted to his laptop and whether upgrading to the 173 driver like you did will also fix his issues? My PC seems to be behaving so far since disabling the 'Sync to Blank' although it's still early days... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/781402 Title: Ubuntu 11.04 / Unity freezing when screen is 'woken up' -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
