Can't get Kwin desktop effects to work

[re-entity]

After installing 9.04 64 I installed the Nvidia driver 1.0-4050 which gave me a few problems but Kwin did work.

I decided to install 180.29 to try and fix the other problems. That didn't work but upgrading again to 180.45 did. Only now Kwin will not start.

I used Nvidia Settings to re-write my xorg.conf

Trying to enable desktop effects from System Setting > Desktop Effects > General gives the following error:

Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.

Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.

Any help appreciated.

Re: Can't get Kwin desktop effects to work

There's nothing jumping out at me that's "wrong" in the /etc/X11/xorg.conf file. Probably it is an issue with the driver installation itself. If, in a Konsole window, you run glxgears, does it work? If you open nvidia-settings, what does it say about OpenGL and GLX?

You didn't say how you installed the driver. EnvyNG is normally the most straightforward method:

sudo apt-get update && sudo apt-get install envyng-qt

Then get out of X with Ctrl-Alt-F1 and shut down the X server with

sudo /etc/init.d/kdm stop

then run EnvyNG in text mode with

sudo envyng -t

and follow the menu. Since you have a previous driver installation, first choose "Uninstall" or "Remove" the driver, then choose menu item #1 "Install the Proprietary Driver".

Immediately upon completion of the installation routine, and BEFORE you restart X, run

sudo nvidia-xconfig

to configure a new xorg.conf file.

Then run

startx

and you should see things working correctly, including GLX, desktop effects, Google Earth (when installed), or whatever.

Re: Can't get Kwin desktop effects to work

glxgears
Error: couldn't get an RGB, Double-buffered visual

glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig

I installed the 180.29 driver by downloading the drivers and installing them with dpgk after stoping kdm and dropping to Ctrl+Alt+F1. I had a few broken dependencies but managed to fix those. After rebooting I was offered the latest drivers by the update manager.

Re: Can't get Kwin desktop effects to work

i would try to reinstall the driver w/ envyng (see dibi's post above)
my guess is something had gone wrong w/ your install last time.
