Hi guys.
Fresh 42.1 setup with NVidia Geforce Go 7950 GTX (Dell XPS M1710):
With default Plasma 5.4.2 I run into trouble with desktop compositing. Finally I can’t set compositing to active under OpenGL2 backend. XRender seems to work but is not an option. Too slow.
Some infos:
I installed the latest official NVidia 304.131 driver from the NVidia repo. Then I blacklisted the nouveau driver in /etc/modprobe.d and I put nomodeset string in the kernel cmdline. After restart I verified that the nouveau driver wasn’t loaded and that the NVidia driver worked properly.
In Plasma Systemsettings->Display and Monitor->Compositor-> OpenGL2.0 and GLX is selected.

**Compositing
===========
Compositing is not active**
This shows compositing is not active and I cant get it to run with OpenGL2. No idea how. No matter what I try.

So after testing around I decided to add http://download.opensuse.org/repositories/KDE:/Frameworks5/openSUSE_Leap_42.1/ repo and make a zypper dup (I know diff between up and dup) to update to Plasma 5.5.2 and Frameworks. Then I removed the NVidia repo and the G02 driver. After that I manually installed the NVIDIA-Linux-x86_64-304.131.run driver from the cmdline. The compilation and installation worked without any errors and after a restart the driver runs without any problems.
Everything seems to work but still no desktop effects because compositing is still not active, even under Plasma 5.5.2. The last thing I did was to add the X11:XOrg repo for up to date mesa stuff and I switched to Kernel 4.1.15. But that also doesn’t take any effect on activating compositing under plasmashell. I dont know where to start troubleshooting. So what you mean, is this a Plasma or NVidia issue, or what? Any help or workaround possible?
Thx, Kai
