 Posted: Wed Mar 20, 2024 1:40 pm Post subject: Desktop freezes, how can I check what's the issue? |
 |
|
Hello,
I have a somehow recurring issue over these past days, as sometimes when I start my desktop session, the PC completelly freezes. I can see the image, but mouse nor keyboard seem to respond. I've tried switching to the other consoles without luck, I just need to push the reset button on the PC Case in order to reset the PC and start again.
I haven't been able to indentify the cause of the issue, since it doesn't happen all the time. The only common factor I've seen is that it happens between 1 and 2 minutes after I login to the desktop.
I'm using syslog-ng, but I believe the configuration its the default. Is there any way of trying to check what could be the issue? Maybe some more logging or anything that could help identify what could be the issue of these freezes.
| Code: | @version: 4.6
#
# Syslog-ng default configuration file for Gentoo Linux
# https://bugs.gentoo.org/426814
@include "scl.conf"
options {
threaded(yes);
chain_hostnames(no);
# The default action of syslog-ng is to log a STATS line
# to the file every 10 minutes. That's pretty ugly after a while.
# Change it to every 12 hours so you get a nice daily update of
# how many messages syslog-ng missed (0).
stats(freq(43200));
# The default action of syslog-ng is to log a MARK line
# to the file every 20 minutes. That's seems high for most
# people so turn it down to once an hour. Set it to zero
# if you don't want the functionality at all.
mark_freq(3600);
};
source src { system(); internal(); };
destination messages { file("/var/log/messages"); };
# By default messages are logged to tty12...
destination console_all { file("/dev/tty12"); };
# ...if you intend to use /dev/console for programs like xconsole
# you can comment out the destination line above that references /dev/tty12
# and uncomment the line below.
#destination console_all { file("/dev/console"); };
log { source(src); destination(messages); };
log { source(src); destination(console_all); };

Try Ctrl+Alt+Del to see if that will reboot the PC. If it does, your syslog output
should contain some messages near the end that may help.
If it doesn't work, the trouble with the reset button is that syslog won't get messages that are in buffers, so you probably will miss just the information you want!

That looks like a kernel panic. If so, you have a stack trace on the VT1 console, but alas it's too late to switch.
So, you boot to a console and start the graphical session manually ? And the freeze occurs only after you start the graphical session ? You can work at the console as long as you want ?
If so, take a look at https://wiki.gentoo.org/wiki/Kernel_Crash_Dumps . You set memory aside at boot time, in which you will preload a recovery kernel. If your running kernel panics, the recovery kernel will warm-boot and you will have a file /proc/vmcore that you can save for later analysis.
The analysis is done with the dev-util/crash utility. It's easy to extract the panic message and stack trace. Sometimes that's all you need. It's more work to dive in and debug the crash.
If you need more help I'll dig up my notes (on this forum) and see if I can make sense of them after all this time. |

It doesn't need to be kernel panic from the description provided - mostly because description isn't very verbose.
"Desktops" are quite nasty as they take control of the keyboard and if they crash but don't return to shell you won't be able to switch to different session/TTY/VT.
Good practice is to have SSHD service running - then you can try to login to your system from outside and if successful switch to other session and/or kill the session that crashed.
With systemd it is done through loginctl. Command help is self explanatory. For other init systems I have no idea how to do anything.
One thing to note - if you play audio and the audio continues to play it is a good sign system is recoverable.
If that audio is supposed to come from crashed desktop then it not playing is not a good indicator system crashed. It is depending on how it sounds like - very short looping audio is most likely kernel panic/crash.
As for troubleshooting - since hardware is also subject to failures it is always recommended to rule hardware issues before tinkering with the system trying to repair it. For that best to have secondary configured system. Of course it can be Windows.

On such systems where the `sys-auth/elogind` package is installed and in use, `loginctl` is available. |
