I can't find the exact thread, but another user was able to avoid this problem by mounting /tmp to RAM.
To do this:
-Open a terminal and run "sudo pluma /etc/fstab" (replace pluma with gedit if you're using Cinnamon)
-In the document that opens, add a new line that reads:
- Code: Select all
none /tmp tmpfs defaults 0 0
-Save and close the document
To make sure you did it right, run "sudo mount -a". If no errors pop up, it should be ok.
/tmp will exist whether you add it to fstab or not. It's your temp file directory, and it should always
When the OS has difficulty using your /tmp directory, that error will occur. There are different causes, so the above may or may not help.
I don't think the home folder or bottom panel are related to this issue. I would think the bottom panel problem pertains to its config file not being read, or perhaps having MATE's cache folder not writeable. Another problem that could have multiple causes; I'm afraid you'll get no concise answer from me
