Hi all, I’m new here. Hope this is the right place to troubleshoot.
So I was customizing my new install of Manjaro last week, and I noticed my gufw settings had not persisted after a reboot. So I flipped the switch back to on and rebooted to check if the firewall would automatically start like its supposed to. However, I was met with a blank screen and the only thing I could do was to log in via tty to troubleshoot. After bumbling around for far too long (the shell literally told me -bash: /dev/null: Permission denied
, yet I still spent much time looking elsewhere), I discovered that /dev/null’s permissions were set incorrectly to crw-rw-r- -, keeping the window environment from starting. Setting the permissions to crw-rw-rw- allowed me to start the window environment with startx
, although it hangs for a random amount of time before starting Cinnamon, which is rather irksome. Furthermore, shutting the computer resets the permissions, requiring me to run sudo chmod o+w /dev/null
every time I start the computer.
I have been stumbling through this week manually setting the permissions every time I boot the computer, but I’d prefer to have a system that works the way its supposed to and actually boots quickly. Does anyone have any idea what went wrong here? My kernel is Linux 5.15.32-1, if it’s any use. Gufw did indeed turn itself off again, but I believe it has nothing to do with the issue as removing it does not solve the issue.
For what it’s worth:

Please let me know if I can provide any additional information that would help solve the problem, or if I didn’t explain well enough. Thanks!
