No desktop effects after routine update

[Frank616]

Just installed the latest updates on a Dell M6600 with nVidia Quadro 3000M video card and nVidia 346.96 driver. I had issues with the driver manager quitting early when trying to choose the nVidia driver, and leaving me with 640 x 480. Finally rebooted and redid the driver manager, and now seem to have the right driver installed, but I get the attached messages, and no desktop effects.

Any suggestions?

Thanks.

Check the compositor setting in System Settings (I can't recall exactly where it is stashed in KDE 4 - probably in the Advanced tab in your screenshot) - I will bet that it is set to xrender. You should be able to set it back to opengl version 3 (or 2).

Claydoh:

Yep! That got it!

So, how did this come about? I've never touched that setting, and it worked before. Has something major changed in the backend?

Thanks.

Frank.

No, Plasma detected that it could not use opengl when you were having driver issues, and set it to xrender so you could at least get to a usable desktop. it probably didn't notice that all was well after you got things fixed.

Yes, check there first... it likes to revert back to xrender for fun I guess.
