Opensuse Leap 15.4 Wayland Session Login Loop

linuxero · May 13, 2023, 8:32am

Hello friends

I quite like OpenSuse, it’s quite nice that it doesn’t cause viruses except for minor problems. But I have a problem, I think something went wrong after I disable KDE Wallet in the settings because it keeps popping up. Or, more likely, it happened when I connected it to the home path via YAST partitioning to automatically mount the partition with Windows 10 installed.

The problem appeared when the laptop restarted and was basically a login loop. Every login attempt seemed to be successful, but it would eventually redirect me back to the login screen. Fortunately, I was able to overcome the problem for X11 session and with snapshot rollback I can now log in without any problem. However, I still have a login loop for Wayland.

Hello, welcome to the openSUSE (yes, it is written this way) forum.

Sorry, but I do not quite understand this. KWallet is a feature of the desktop and thus works at the users level if a user is logged in.

Mounting file systems at boot is something done on the system level and way before a user is logged in and thus long before KWallet may be activated (or not).

Also I do not quite understand what you mean with “connected to the home path”.

It is always better to not only tell some story, but to show the system evidences that prove your story. Thus in the case you want to tell us something about a file system to be mounted at boot, please show:

cat /etc/fstab

to allow all of us to see what you mean.

When I login, at startup KDE was asking me Windows’ partition password to be mounted. Then I investigated on this and applied some advices. Like below;

Then something went wrong and I undo changes so my fstab is normal at the moment, repaired X11 session login loop but Wayland.

*Sorry if my English is not enough to clarify my case

hcvv · May 13, 2023, 10:20am

Ok, thus the first thing is that because you removed the entry in /etc/fstab, we still have no idea what it looked like.

Second is about that “Windows’ partion password”. Do you mean the Windows file system (what type is it? VFAT, NTFS, …?) is protected by a password?

Or maybe you were asked for the root password?

I am afraid we need the exact message you got.

And you still did not answer what you mean with “connected to the home path”.

linuxero · May 13, 2023, 10:28am

Windows partition is NTFS not crypted but just login password.

And you still did not answer what you mean with “connected to the home path”.

An advice was that to set windows partition mounting option into /home for auto mount and never ask root password again. After this config or KDE Wallet disabling had broken my session login as I said. At least, I think so.

hcvv · May 13, 2023, 10:34am

I d not know where you found the “advice” to mount the Windows file system at /home, but it is a very bad one. You have already a /home that is populated with the home directories of your user(s). When you mount something over it, that will all become invisible and I doubt very much that is what you want.
It will make login of the user even impossible IMHO.

I still do not understand about that password, but as you removed the dangerous entry in /etc/fstab, we may probably forget that.

linuxero · May 13, 2023, 10:36am

hehe

now how can I repair wayland login loop? snapshots also could not fix.

hcvv · May 13, 2023, 10:43am

I hope others will join here. I have no Wayland experience at all (just using X11 for ~30 years and it satisfies me).

Also I have no idea what you may have damaged with your strange action. I hope sincerely not much, but you never know what happened when trying to login and the software could not even find your home directory.

For the moment, just be glad you can work with X11.

And BTW, I doubt very much that KWallet disabling has anything to do with this.

deano_ferrari · May 14, 2023, 3:35am

My suggestion to start with is to create a new user in the KDE Plasma X11 session, then logout, and try to start a Plasma Wayland session, logging in as the new user. Does that work?

If not review the following KDE troubleshooting guide.

deano_ferrari · May 14, 2023, 3:57am

Also, examine the journal output following an attempt to start a Plasma Wayland session…

sudo journalctl -b | egrep "kwin|plsma" > out.txt

You can upload lengthy text using the susepaste command (you may need to install it first) using something like

susepaste -t "Debug _output" -e 87600 -f out.txt

then share the link that it generates here so that others can review.

For more info, refer ‘man susepaste’.

Yeap, created a “test” user and logged in Wayland session successfully. It worked, so the issue looks related to my user.

susepaste did not give upload link, just stuck on terminal. then I searched the out.txt and uploaded by hand.

This is on X11

And this is on Wayland

deano_ferrari · May 14, 2023, 7:31am

Yes, a likely issue with a user configuration file. I can only speculate that it may down to ~/.config/kwinrc (but there is no direct evidence for that yet).

Unfortunately, the log you shared is incomplete, and both contain mostly overlapping output anyway. So, nothing definitive learned from these.

You could try the debugging step I linked to earlier, and upload the resulting ~/startplasma-wayland.log to susepaste for review. (The commands are run from a terminal eg VT4 as the user account under investigation.)

I have no idea coz just pasted what it given to me directly.

deano_ferrari · May 14, 2023, 7:33pm

I’m not sure what causes KWin to crash there, but perhaps try removing (or renaming) ~/.config/kwinrc for the user concerned, and then attempt to login as that user form your display manager login screen. Any different?

linuxero · May 14, 2023, 9:50pm

tried several times but did not help.

deano_ferrari · May 14, 2023, 11:46pm

Hard to say what you did previously that caused this issue, but the pragmatic option may just to be backup the existing user’s ~/.config/ directory and default configs will be regenerated as required. Application-specific configs can also be copied back if needed for any customised settings. I can’t really offer any further advice around this, and clearly the Wayland session works as expected with the new user account.

linuxero · May 15, 2023, 4:31am

any option to copy new user’s config for wayland to my daily user account. that can help?

deano_ferrari · May 15, 2023, 9:10am

You could use something like the following…

sudo cp -R /home/USER1/ /home/USER2/ && sudo chown -R USER2:users /home/USER2/

linuxero · May 15, 2023, 9:13am

is this also okay for my x11 session? looks complete home folder changing.

deano_ferrari · May 15, 2023, 9:17am

Yes, you can do it from an X11 session, or do it at runlevel 3 (multi-user mode) from a VT.
