Wayland session failing to start - Current
 
The problem, I can not start a Wayland session on one system. The symptoms; the monitor show only a cursor in the top left corner on a black background. The keyboard is unresponsive. Ctrl + Alt + backspace does nothing.

I have re-installed these files :

Code:
ls -l /var/lib/pkgtools/packages | grep wayland
-rw-r--r-- 1 root root    6634 Feb 17 06:56 kwayland-5.79.0-x86_64-1

-rw-r--r-- 1 root root    814 Feb 16 17:50 xisxwayland-1-x86_64-3
-rw-r--r-- 1 root root    1098 Feb 16 17:51 xorg-server-xwayland-1.20.10-x86_64-5
The problem persists. Wayland sessions will start on my other three systems, all systems are fully up to date. The updates all come from the same server, a Pi3 with DH attached.

I can kill the hung session by connecting to the system via ssh, displaying the active wayland files, and killing the active ones.

Here is the output from the wayland session log.

There is a QT session management error. Any ideas how I fix this?

This system is the last one I have running on an MBR BIOS system. My other systems are on GPT and UEFI. Not sure if that is relevant or not.

Let me guess...

The graphics card is NVIDIA?

I have friends who say that they experienced lockups with Nouveau, and the proprietary blob is usable only for the really modern cards.

Also, the Wayland needs at least a support for OpenGL 2.1, if you have only OpenGL 1.4 looks like that it will not work.

Yes, I have an Nvidia card on the both working and failing systems. The failing system:

and one of my working systems,

Did you noticed the differences on third line?

Looks like you have some issues with the proprietary blob installation on the failing box.

This could be true, however, it works perfectly running X11, either KDE or XFCE. So, if its the driver Nvidia blob, how to get a handle on the problem?

I suspect this is just another problem with Wayland. Its buggy at best, and is still very much a work in progress.

Here are a few of the things that fail in Wayland.

If I'm running chromium, opening up the bookmarks, with the mouse pointer, and navigate to one of the items like Slackware, and try to navigate into the sub menu, it will not work with the mouse pointer, the highlight shoots up the main list. I can use the sub-menus IF I use the arrow keys.

Geeqie seg-faults in Wayland, works perfectly in X11.

If I try to log out of Wayland, after closing all applications I started, every background app for KDE blows up, I wind up with about 20 failure messages on the screen asking if I wan to report a bug to KDE.

I'm interested to here from other slackers on their experience with Wayland.

From my memory, Nvidia binary drivers weren't working properly on Wayland. It seems they have some patches that are pending or recently added that will hopefully improve Wayland support on Nvidia hardware using the binary driver.

I'm not sure if the issue is tied to drivers or just some issues with Wayland itself, but issues like these are why it is not yet the primary display server in Slackware (and probably any distro).
