.xsession-errors is still causing problems.

Xserver - X Window System display server. Perhaps the audit level has been mis-set. Should be level 1. Can't figure out if it is set, or where it is set.

Interesting file to look at is /var/log/Xorg.0.log. Using config file /etc/Xaa/xorg.conf.

Maybe I should be looking at kde.

Huge .xsession-errors. Here is one suggestion.

Had the same problem with 11GB .xsession-errors. Fixed it with a solution I found to disable the recent history too.

rm .xsession-errors
touch .xsession-errors
sudo chattr -i .xsession-errors

Simply delete the file. Create an empty file. Set the immutable attribute. Which makes the file protected against writing and deleting. Nothing can be logged.

Note that until you logout the file space deleted is not unallocated because the file is being held open.

I did it. If I break X when I reboot, then I don't know what I will do.

38: rm -f .xsession-errors
39: touch  .xsession-errors
40: lsattr .xsession-errors
-------------e-- .xsession-errors
41: sudo chattr -i .xsession-errors
[sudo] password for steve: 
42: lsattr .xsession-errors
-------------e-- .xsession-errors
43: sudo chattr +i .xsession-errors
44: lsattr .xsession-errors
----i--------e-- .xsession-errors
45: rm .xsession-errors
rm: remove write-protected regular empty file '.xsession-errors'? n
    

I rebooted, and I think it worked.

6: lsof -nP | grep 'deleted'
7: df

The following is from the man page of chattr.

A file with the 'i' attribute cannot be modified: it cannot be deleted or renamed, no link can be created to this file and no data can be written to the file. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this attribute.
