Black screen for one user after upgrade from 13.2 -> 42.1 -> 42.2 (really stuck...)

Really stuck and would really appreciate some help, please

I’ve upgraded from openSUSE 13.2 to leap 42.1 and then 42.2, I’ve read at length the article here:

https://forums.opensuse.org/showthread.php/525135-Black-screen-after-a-huge-update-to-Plasma-5-10-and-libQt-5-9

And many many others. I’m using what I believe to be stock repos:


zypper lr -d

I can log in as root and the desktop is fine, I can log in as a new local user and the desktop is fine, but if I log in with my network credentials (I’m at work - home dir is auto-mounted and available as I can ssh in) then I only see the wallpaper, the mouse icon and nothing else (tried plasma 5, Gnome and Gnome Classic). If I use a VM with leap 42.2 installed and log in with my network credentials it works fine… There’s something about my account on this particular machine. I have tried deleting all .* files in $HOME but that doesn’t work either.

I have access to IceWM and was able to replicate this:

I’m not sure what else to try?

Maybe a permission problem?
Qt’s QML/QtQuick (used by SDDM and Plasma) uses OpenGL which in turn requires direct access to the graphics hardware.
And also GNOME uses OpenGL.

What does glxinfo (package Mesa-demo-x) say when run as this user?

Try adding the user to the group “video”.

I see much of the same when I successfully log in to another machine except the file contains much more output!

Are there configuration files stored outside of my home directory that relate to my login on this particular machine? I found and removed /var/tmp/kdecache-userName, is there more?

Here is a snippet from /var/log/Xorg.0.log that shows a single error:

I think this benign given as I can log in as another user on the same machine… Here’s what I try removing form my home directory:

 
rm -rf .xsession-errors-machineName2:0 .xsession-errors-machineName1:0 .Xauthority .cache .config .xsession-errors .dmrc .kde4 .xdg_menu_cache .esd_auth .gtkrc-2.0 .dbus .local

Thanks for reading this far. Still really stuck!

Apparently you missed my previous reply…

Are there configuration files stored outside of my home directory that relate to my login on this particular machine? I found and removed /var/tmp/kdecache-userName, is there more?

Config files are stored in ~/.config/. What you deleted are temporary files/caches for KDE4, Plasma5/KF5 uses ~/.cache/ instead.

Here is a snippet from /var/log/Xorg.0.log that shows a single error:

That’s no error.
You don’t have fglrx installed, so it cannot be loaded and the system uses radeon instead.

Thank you for responding, I think we were posting at the same time and I missed your response.

I looked the video group using YasT and note that gdm was the only user, the local user and the network user were not members of this group. I’ve added both users to the video group.

I’m not sure how much you need to see, please let me know if you want more output, I piped the output to a file (glxinfo > temp.txt). I’m using a separate computer and ssh’ing to the machine.

Just a thought: could there be ‘older’ widgets involved?
A trick: logout, go to the console, login with your affected username, and


mkdir SAVED_PLASMA_CONFIG
mv ~/.config/plasm* SAVED_PLASMA_CONFIG

logout, return to login screen, login and see if it works now.

Another one I ran into: remove ~/local/share/kscreen

7

Looks good, but that’s after you added your user to the group “video”.
Did you try if Plasma starts now?

8

Yes - it still didn’t work, I changed from iceWM to Plasma5 on the login screen. Just trying Knurpht’s trick right now.

Thanks you for helping.

As mentioned above, I’ve essentially tried this by removing everything in ~/. (all .* files and directories). I tried the move anyway (from my ssh console) and then tried logging back in again. Before I did this a can confirm that ~/.local/share only contains a directory called kactivitymanagerd (no kscreen dir/file), this then contains a resources directory which contains:

-rw-r–r-- 1 user group 12288 Jun 22 10:06 .nfs00000000000000e800000010 (changed to user and group to protect the innocent!)

The login still did not work.

10

Fixed! I wish I could leave explicit details for those who follow but I did a whole bunch of things (including deleting a lot of old files)… From a remote shell I watched the system using journalctl -f, this clued me in to the fact that the display manager was using kdm so I switched it over to sddm by editing /etc/sysconfig/displaymanager, the file now contains this:

# Here you can set the default Display manager (kdm/xdm/gdm/wdm/entrance/console).
# all changes in this file require a restart of the displaymanager
#
DISPLAYMANAGER="sddm"

I was suspicious of how my home directory is mounted in /etc/fstab (the setting seemed very basic) so I made some adjustments to the mount and rebooted. Just before rebooting and while logged out of the troublesome account I used lsof /usr5 (/usr5 is the mount point where our home directories reside) to see if anything was still using this filesystem, which it was (not good and perhaps the root behind the suspected permission issues?!). I did the reboot and then removed the .* files again (from a remote ssh console session). And hey presto it works…

Certainly the journalctl -f helped get me started!

Thanks for helping me guys, it’s really appreciated.

11

Confused at what you did

All mounts are listed in /etc/fstab the /home mount should point to the partition that holds your home directory. If not present the OS will create a new home which of course will be empty except for the default files. Deleting all files and directories from your home that start with a period will remove all configuration and perhaps some data for your user. Files that start with a period are considered hidden files, but that does not mean they are not used.

12

It’s a NIS setup, so our network based home directories are setup not in /home but in /usr5 which resides on a network based disk (I can log in to any machine and access my files). I do have a separate local account on the machine whose home directory is in /home and that works fine. I think the root of the problem lies in how the network directory (/usr5) was being mounted.
