I had originally asked something related to this on another post but this is more specific. I apologize if this is considered cross posting.

I am running fedora 23, a brand new install, with Plasma version 5.5.5 . Been attempting to get the desktop cube working.

There are 4 virtual desktops, in one row.

As was suggested by someone on the forum, I checked /usr/lib64/qt5/plugins/kwin/effects/configs to see if kwin_cube_config.so was there and it was! However, in my "system settings" dialog, under "desktop effects", I do not see "desktop cube" as an option.

Under "virtual desktops", I do see under "animation" "Desktop cube animation".

I also just noticed that in the "virtual desktops" setting, even though "Animation" is set to "desktop cube animation", under "shortcuts" there is no "ctrl+F11" shortcut. Therefore, i simply conclude that Desktop cube animation is simply not enabled.

Has anyone gotten the desktop cube to work in fedora?

Thank You
Tom

Just posted the requested data to http://paste.kde.org as tcipollone KDE Kwin data.

Thank You

Could you please provide a link for it? Otherwise I won't find it.

in the archives.

What did you do to that output?

Anyway,
> Compositing is active Compositing Type: XRender

run "kcmshell5 kwincompositing" and change the type to OpenGL - since that might fail, post the output of "glxinfo" as well.

Yes, you were correct, changing the compositing type to Opengl did not work. I rebooted.

I just posted the output of glxinfo to https://paste.kde.org/all under the title of "tcipollone glxinfo output"

BTW, you had asked what I had done to the output of qdbus org.kde.KWin /KWin supportInformation. All that I did was "echo $(qdbus org.kde.KWin /KWin supportInformation) > file.txt". I did not know how to get the formatting any better.

Thank You

Virtual machine or software renderer because you forgot to install the GL driver for your hardware?
("lspci" in case you don't knwo what your hardware is

Yes, I am running the default nouveau driver. I have a gtx960 graphics card.

Code: Select all

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)

On this install i did not load the Nvidia driver because it is usually such a pain. You, know, having to compile the driver against the kernel and all. Usually something goes wrong.

Are you saying that desktop cube and other advanced graphics will not work unless I install the Nvidia driver? or, are you saying that there is an OpenGL driver that I need to update for my hardware? Please clarify.

Thank You for your help.

Tom

you're *not* running nouveau, likely because it's still blacklisted (kernel module) or because the nouveau-dri module (from mesa) isn't installed or xf86-video-nouveau (the xorg driver) isn't installed.

I believe you. What would be your first and second recommendation?

And thank you again for all of your help.

You mentioned above that I am not running nouveau.

The result of command sudo lspca -k:

You'll require MESA 11.2 & Linux 4.6 for Maxwell support - or the nvidia blob.
If you want to avoid the latter by all means, you'll have to run KWin (and better any GL client) on the intel chip.
