I’m experiencing strange issues with latest kernel 6.8.5-1.
I’m running stable branch KDE plasma. I was on 6.7 - I see that it has been removed, aside the RT version, so I can’t give you the exact version. I was using automatic login as user, with session Plasma(wayland), set in the login screen (SDDM) settings.
I installed latest kernel yesterday (“sucessfull”), and rebooted. The system never rebooted properly - I got a black screen, not even reaching the manjaro splash screen. After a while, I did a long press on the power button to force a shut down, then booted the computer again. I selected the latest kernel in the grub menu options, then booted. I do not remember having other further issue for this session (yesterday).
Today, I got notifications of available updates, for linux56 and linux58 in the extra repository. I installed them, and restarted. I got the black screen again, no splash screen. I used the power button again to force a shutdown, and booted anew, and got to the splash screen, where the throbber kept going for an unusual amount of time, until it ultimately got to a command line interface, that suggested to me to either enter the root password for maintenance, or press Control D to go further (sorry, I do not remember the exact words).
I entered the password, then tried to start a wayland session with startplasma-wayland. I got an error stating that qdbus was disconnected, and asking me to call qdbus, which I tried by typing qdbus in the command line, and got something that I do not remember - something ‘not defined’ (sorry, my memories are not as sharp as I’d like), asking to define the address of the session…? perhaps? At this point, I gave up, rebooted using reboot command, and selected the LTS kernel in the grub menu options that I keep installed for these occasions.
I booted without any problem. I went to the SDDM options, selected plasma(X11). I removed the kernel 5.8.5-1, and then checked and removed all orphaned packages, checked for updates.
I rebooted, installed the latest kernel again, and rebooted once more, selected the latest kernel in the grub menu options. I got the black screen again and no splash screen.
I pressed the power button, booted, and got to the splash screen, with the throbber going for unusually long again, then the command line interface. This time I pressed control D, and got into the GUI.
I tried to reboot again, and I get the black screen, no splash screen, where I need to use the power button, start again the computer, then get the normal boot sequence.
Perhaps of interest : I’ve got a version of plymouth that is newer than the version in the repositories, and I’ve seen the post about it, but I’ve got no idea if it is related.
Feel free to ask me the info you need. I don’t know what is relevant, and don’t want to clutter the post with useless information, so I opted for not providing anything.
