Re: System hangs at GDM login or a bit later...
Well, I've been trying a couple of kernels, 6.1.0-17/11, and with both the system freezes sometime in the way explained below. I did a RAM test which was passed successfully, but I guess I should also make a GPU RAM test, something I really don't know how to do. For the usual RAM I used MEMTEST86+ as a live ISO. Now I'm trying kernel subsubsub version 16 since a couple of days ago and the system has not frozen yet. But I'm not very optimistic. Anyway, how can I test GPU memory? Best regards.

I went back to 6.1.0-17 kernel a couple of days ago and the system didn't freeze so far. It's not enough to say the problem is solved, because it is very random, but two days without freezing is encouraging indeed.

If not, then ... maybe a hardware problem. Start with a memory checker. Then move on to disabling the GPU. Jeff
System hangs at GDM login or a bit later...
Hi, I'm having this annoying behaviour from GDM (or something related). Quite ofter, after the GDM login screen appears, the host freezes completely: every input device is unresponsive, no ssh connection from another host is possible any more, no CTRL+ALT+CANC/F1-F6 is working. But the same happens also while I'm typing the username or the password, or after the login screen disappears because the login was successful, or even a bit after the dash has appeared at the bottom of the screen. Looking at boot.log, the last line before the next boot reads "[ OK ] Started gdm.service - GNOME Display Manager". Looking at syslog instead, the lines are not always the same, but usually there is something like this: 2024-03-27T17:57:25.479168+01:00 SW-GIULIANO /usr/libexec/gdm-x- session[1831]: (II) Initializing extension RECORD 2024-03-27T17:57:25.479455+01:00 SW-GIULIANO /usr/libexec/gdm-x- session[1831]: (II) Initializing extension DPMS 2024-03-27T17:57:25.479734+01:00 SW-GIULIANO /usr/libexec/gdm-x- session[1831]: (II) Initializing ext2024-03-27T17:58:25.469753+01:00 SW-GIULIANO systemd-modules-load[394]: Inserted module 'lp' 2024-03-27T17:58:25.469853+01:00 SW-GIULIANO kernel: [ 0.00] microcode: microcode updated early to revision 0xf4, date = 2023-02-23 Please note how the third line suddenly ends with "ext", followed immediately by the first line written by the next boot sequence. The"gdm-x-session" lines above are just the last of a very long list. I can provide other logs if requested. Any hint would be veri appreciated. Best regards.
