Title:
  no desktop effects on a radeon 3100 graphics card in saucy

Status in “linux” package in Ubuntu:
  New

Bug description:
  On raring, my radeon 3100 was working pretty well. desktop cube switch was working, for example. Blur effect slowed the desktop down. When I upgraded to saucy on sept. 25 I soon noticed that the desktop was very fast. I could even enable blur effect and it didn't do any harm. After the update on Sept. 30. all the graphics performance was gone. Most desktop effects are disabled. Compositing type is set to XRender, Qt graphics sytem is set to Native. When I try to set Compositing Type to OpenGL and Qt graphics sytem to Raster, I get the message, that 6 desktop effect could not be enabled. Detail window says this is because they require OpenGL. I have no idea where to start digging, so any help is appreciated.
  regards,Hans-Peter
  BTW: I'm not using the fglrx driver. I guess they quit support for the 3100 a year ago, or maybe two (or they messed something up)
