colorfire crashed with SIGSEGV - all screen savers fail

[[e-mail]]

When selecting screen-savers from the System->Preferences menu, there is no problem with viewing and selecting them. However, when the screensaver timeout elapses, and the screensaver is called, the screen darkens prior to beginning the screensaver - then stops, and brightens again. No screensaver appears.

Screensavers have never worked since I installed Intrepid, but this is the first time this has caused a fault to be reported.

Hi,
Unfortunately, the automated bug reporter was not able to salvage a good report out of the crash. Furthermore, from what little info is present it does appear that this is a problem with the OpenGL implementation of the graphics drivers for your nvidia card. Unfortunately, the nvidia video drivers are closed-source pieces of software, meaning that Ubuntu developers have no access to modify it or fix bugs in it, only nvidia can.

Thanks for your understanding, and have a nice day.
