    Crashing usually means a hardware failure. The system log files should have errors and/or warnings showing any issues. Check those using whatever method you like. There is probably a log viewer in...

    Here's a working, simple, setup (I used copy/paste, so no chance of mistake):

    [SOLVED] Re: man page for starting terminal

    Check the process table. That's the table maintained by the OS of all running processes.
    You can do that anyway you like. I'm old and have an alias - psg - which stands for ps-grep.

  6. Re: Is it true that SSDs fail withot warning ? How to know the health of my SSD ?

    I've had SSDs fail slowly, giving lots of feedback and I've had one fail after about 2 yrs of use, no warning at all. Both were "value" SSD brands - i.e. cheap.

    [lubuntu] Re: Does Ubuntu still support CPAN.

    cpan has moved to cpanm. If cpan.org is even still up, that's a surprise. The perl community moved to cpanm about 8 yrs ago.

    Also, if you are loading modules from cpanm (or formerly cpan), then...

  10. [SOLVED] Re: External Drive Encryption Using KDE Part Manager In LXQT

    That depends on what "recent" means. If it is 12 yrs ago, then I suppose that could be true. Around here, very few people run any system older than 16.04.

  11. [ubuntu] Re: Can't boot; hard drive reporting full, but it isn't

    Please test a restore, since it is almost 100% certain that critical metadata about the files will be lost going to a non-Linux file system like that. I hope the restore actually works, but doubt it...
  12. [ubuntu] Re: Can't boot; hard drive reporting full, but it isn't

    For large files,

    sudo find / -type f -size +1G # files larger than 1GB

    I had to do this earlier today after seeing a backup with...

    yes, you can ssh in, then use any of the thousands of CLI tools.
