I tried downloading three pdfs via google drive through firefox.
All of a sudden, my laptop - lenovo ideapad 330s heated up while the pdfs havent finished downloading at all.
I downloaded htop to see what was happening.
All I saw that was suspicious was libexec tracker-miner-fs and lib-exec-document-portal running as user - me. I didn't get any idea... finally decided to close firefox without waiting for the download to complete as they are taking such a long time for a 20 mb file. I saw that all three were partially downloaded missing a few hundred pages.
I deleted the partially downloaded file via the GUI by clicking the delete button.
The laptop was still overheated.
I looked up at top and saw that I was running a Priv cont process.
As I understand, It is used to run processes as higher Privileged? I kill the process with its PID and reboot the laptop.
I don't know If I am paranoid or something. Can someone make any sense out of this? after the reboot, the heating subsided.
I also looked at the auth.log located at ~/var/log/auth.log - its output
I cant help but notice that pam_unix is trying to access /etc/securetty which is a really badly named dir. The dir didnt exist in my local storage and thus returned an error as seen in the log.
The pdfs had an average size of 20 mb and the average number of pages were 500.
Or is it a bug with firefox? As I understand through other posts, the print in firefox isnt working well. and I used the print to pdf in firefox to download my files.
It is Ubuntu 20.04 - Focal fossa.
