My laptop seems very finicky with linux and enjoys periodically freezing. Some distributions are more stable than others and I’d like to keep testing other distributions without reinstalling/ downloading/transferring all my apps and steam games constantly.
What I would like to achieve is to have my small handful of flatpak apps and flatpak steam games on a separate partition to quickly access while I test and troubleshoot issues.
Is that possible to do with flatpaks?
To this day I have no idea how to even get journalctl errors from exactly before that crash.
Like all this
journalctl -r -b 1and all that doesnt seem to show the right ones.On my debian machine something like
journalctl -b 1 -kshows stuff. There’s also lots of debug files in /var/log/ like boot.log debug, kern.log, messages, syslog.But it somehow needs to be able to store the log on your disk. If the system craps out completely, it won’t get written to disk. The magic SysRequest keys might help if it only freezes. I learned “Raising elephants is so utterly boring.” You might wanna goggle that and learn how to do it.
Other than that, I mostly look at all logs (no ‘-b1’ and search for the place where it rebooted. Sometimes you find other related stuff while scrolling. But my own (old) thinkpad doesn’t ever crash.
I think there are other crash-dump tools available. It believe there’s something called ‘kdump-tools’ available on Debian. YMMV.
