Hi,

Since few days I have some weird problems with latest ktown plasma. After the 1st of April update from KDE 5_18.02 to 03, I've lost window decorations, meaning I'm missing button bar and the stuff that comes with it. I'm unable to alt-tab or maximize windows and most of keyboard shorcuts don't work. Under Konsole settings I have a message that tells me that there is no compositor available and it doesn't matter if I use xrender, opengl 2 or 3 - result is the same. On the other side, glxgears and glxinfo are showing correct output whether with or without primus/optirun. Moreover, konsole works fine under xfce, as it used to before. Xorg.log seems ok.
I created a new user for testing purpose and all symptoms mentioned above are identical.
Xfce or enlightenment are working ok with compositing enabled.
I tried to reinstall plasma with slackpkg and with rsynced packages but in wain. Also made a reinstall of bumblebee, mesa, xorg but nothing seems to help. As I'm completely clueless - any advice is more than welcome.
Regards

KWin is not running? Output should tell you why it's not running, if you start kwin from konsole.
There should be something to read in /var/log/ also.

As a side-note, I've read some gossip about how KWin developer refused to accept hardware that nvidia was willing to provide for him.
If that were true, I guess it should be no surprise the thing's neither tested on nvidia chips, nor quality assured.

Maybe some packages are missing from slackware(64)-current ? Or the from the last updates of KDE 5_18.03 ?

I checked bunch of logs but kwin didn't show up or anything related. But it was kwin related... Somehow libinput didn't upgrade properly and slackpg didn'n pick it up. Upgradepkg solved it.
Thnx.
