Re: Frequent freezing around login screens

Max suggested checking with journalctl which may help, but I am thinking that if the computer is freezing, then nothing can get written to the logs anyway, so searching logs may not help.
For example:
# journalctl --priority=err --no-pager

To be clear, I tried to suggest *no* filter (besides time window) to see last logged action. journalctl output contains dmesg messages and shows them in context. "--priority=err" is just better than "| grep -i error". This filter is still too strict for obscure issues.

I hope that last logged *actions* may shed some light.

I think, the journalctl command above should have other options, but I can not guess what you are trying to achieve.

Before logging in, try to connect to the machine using ssh, preferably other ethernet, but you may try at least to do it from a smartphone and run

     sudo journalctl --follow

There is a little chance to see some messages that can not reach the disk.

If you can, I suggest installing Debian 12 KDE and see if all works or not.  KDE does not use LightDM and instead uses SDDM

KDE and LightDM are independent component. I am writing from KDE session started namely from LightDM. I just do not like SDDM. So if you wish, you are free to install SDDM without full KDE or any other display manager. I am in doubts if it will help. Instead you may try to install xinit, login from VT and execute startx.

RAM test might be a better option. E.g. download memtest86+ .efi file from its upstream site.

P.S.
George, there is no threading "In-Reply-To" and "References" headers in your message.
