When the system is idle, neither disk or memory will be stressed at all. It will probably have ticks set to only occur when necessary to save power, so will mostly just be sitting there. You could try running a video game of some sort instead of firefox or thunderbird. Both of those are large programs with lots of disk and memory usage. A video game should be mostly memory, and video, of course. If it also has a problem, then it is probably not due to the app, but due to another issue. Can you boot into an older kernel? Maybe it's a kernel issue, and a different kernel won't have the problem. Nothing shows up in the logs? Yesterday, when the problem occurred, were there any suspicious entries in the journal. You can look back by running journalctl, and finding the time when the issue started yesterday. I usually use -r option so that the latest entries are at the top of the output. I think there are also disk diagnostics you can run with smartctl. It has a man page. It will show if lots of bad sectors are present. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
