SUMMARY
Trying to run KDE Neon live using current User version image (neon-user-20240307-0714) falls into a loop when logging default user and creates N sessions without reaching the actual desktop


STEPS TO REPRODUCE
1. Download user version neon-user-20240307-0714 (current)
2. Write it down to USB drive with KDE ISO Writer (in my case it is a 4GB USB drive)
3. Run KDE Neon from that USB drive

OBSERVED RESULT
After loading view is gone, black screen with pointer in the middle is displayed and after 3-4 seconds screen gets full black showing only cursor in the top left corner and after 3-4 seconds screen gets back to display the pointer in the middle and so on

EXPECTED RESULT
Default desktop is displayed

The ISO works fine for me running in VirtualBox.

I'll snapshot and make a new ISO and test that on real hardware

Comment 2 Jonathan Riddell 2024-03-14 11:55:57 UTC

The new neon-user-20240314-0716.iso image is similarly working fine for me

Hi,
Just tried with the released version today and stills happening the same. Actually I've tried in another computer and the boot never gets into the live os. Funny thing is both computers have KDE Neon installed and working fine. 
Got a video with the actual behavior here https://file.io/PMa67mAyfGkU (video exceeds weight attachments quota)
Thanks,

Been trying different versions from newer to older and found that neon-user-20240215-0716 works. Whatever version after that one is going on the issue. Tried on 4 different computers (desktop and laptop) and in every case is happening consistently. Guess something was introduced on neon-user-20240228-1346 that's causing the issue.

it might be the switch to wayland by default, e.g. on virtualbox is now needs "3D Accelation" enabled, also EFI
