Just got a old Dell Vostro 3350 notebook, Fedora 33 is running on it in no time. (It is a default Workstation setup, with only Google Chrome browser installed.)
I am new to using Fedora Workstation on a notebook, my previous experience is manly on a desktop machine.
I notice my first issue: My Notebook Screen do not goto Locking mode after idle even for 30 minutes.
In Gnome Settings-> Power, I have:
Dim Screen When Inactive: On (But my screen did not Dim)
Blank Screen: 5 minutes (But my screen did not Blank)
Automatic Suspend: When on battery <On Battery Power On w/ Delay 20 minutes> (But my notebook did not Suspend)
How to reproduce:
Put notebook in battery power.
Do not close Lip
Reboot into Graphical Target.
Logon
Leave it idle for 30 minutes
(I got same result after doing a dnf update and reboot)
Look for BIOS update. It might also be related to GPU driver. inxi -MGxxxz will output useful info.
Browsers can inhibit those settings and Chrome (by default) snoops around even if you didn’t start it up, try chromium or ungoogled chromium-browser-privacy instead.
I am sorry that I have reformat my machine and reinstall Fedora 33 workstation from ISO already.
After this re-installation, the system now correctly blank the notebook screen.
Before my reformat, I failed to preserve a working snapshot of the problematic instance. Thus I cannot continue to try find out what actually happened to that instance.
Thank you very much to everyone that gave me ideas and helps.
