I have faced this problem many times, where /var/log/syslog grew to a very large size, which made my elementary os black screen because the filesystem was full, I have found a solution to this problem, but I have not found what is the cause.

can anyone help me explain why var/log/syslog can have a very large size?

this is the log.

    can you add your syslog in your question? – LinkPhoenix Dec 10 '19 at 0:55
  • @LinkPhoenix can't enter the GUI, in my case the size of /var/log/syslog is up to 90 GB. This problem occurs several times after sleep (lock-mode) within a few hours. – Hasan Suryaman Dec 10 '19 at 1:12

    @HasaneSurvayama some answer is to delete the log and reboot but it is not a solution. Maybe you can do cat /var/log/syslog in recover mode and give use the output for analyse your syslog – LinkPhoenix Dec 10 '19 at 1:22
  • @LinkPhoenix I will that on do the same problem later, because I am sure I will face the same problem, because this time I have already deleted my /var/log/syslog, but is it possible to read a large file (cat)? or is there another way? – – Hasan Suryaman Dec 10 '19 at 3:09

    tail n50 /var/log/syslog will show only the last 50 lines of the file. If you want another number of lines, just change the number. If you wish the output to be not on the screen but in some file you can use tail n50 /var/log/syslog > filename instead. Replace filename with the name of the file you want to create, you can choose any name.extension you want, I recommend the extension to be txt. Without sharing this information, no one can guess what is filling your syslog file with so much information. – Bo rislav Dec 10 '19 at 11:04

i dont know what is producing the gigabytes of error in syslog is a similar question.

I have posted details on a bug here. It is related to VLC (and perhaps other video players). The bug was not solved. But as a way to stop the output, closing VLC apparently works. As per messages in the bug thread, and my own experience, avoiding having a playing video while switching users, and perhaps workspaces, should prevent the issue from appearing. Starting VLC at the command line is an alternative workaround, since all output would go to stdout.

  • Yes, I do that, I'm sure it's an easy way to avoid problems. but somehow the error like this does not happen again, is there an update on the Nvidia driver or other updates I also don't know. but if the problem occurs I usually do truncate on var/log/syslog – Hasan Suryaman May 12 '20 at 22:47
