Dear Guiverc, thank you. As I told Brickwizard, I only intend to use the machine with Open Office, text messages, wordpad (if available) and with a media player. I will also use a printer with it.
The actual apps used makes a big difference, which is what I said.
I don't know Open Office & what it uses, as I've not had it installed for some time, and thus cannot explore what its requirements are. LibreOffice suggested by others would be my choice anyway; but it's a different app.
text messages - I know of no such app. Most GNU/Linux distribution come with text editors, eg. Lubuntu when it used the LXDE desktop came with
leafpad
, as both LXDE & leafpad use GTK2 libraries/toolkits thus share resources. When Lubuntu switched to using the newer LXQt desktop providing the
leafpad
text editor would have been very inefficient on users (and Lubuntu aims to be
light) thus it was replaced with
featherpad
which is actually a more powerful editor, but because it shares resources with the LXQt desktop is
lighter than leafpad would have been.
You mention wordpad, as I'm using Ubuntu currently I tried a search for it (
apt-cache search wordpad
) and it had no results, likewise if I searched for snaps of that name. I don't know it thus can't comment on it, or its requirements. If you used as as generic term for a
text editor, sorry I missed that, but it sounds specific.
Media Player; most systems come with a media player; eg. Lubuntu comes with
vlc
. If you can use the media player the system comes with - it'll be chosen for a reason usually which for many includes efficiency & sharing resources with the rest of the system (
alas not all do this, some are created for new equipment & choose according to their developer wanted tastes/features rather than efficiency of operation; look at the aims of the project for clues)
If you're just starting out your journey with a POSIX or GNU/Linux system, or not tech savvy and just an end-user, sorry my suggestion will likely make no sense.
Qt5 I mention is also used in windows apps, mac OS apps & Android phone apps. It's the
norm for Android apps on the phone for example... ie. what I'm taking about applies to all systems - but most end-users don't want to know this detail; and thus Microsoft & windows app people just add a "6GB RAM required" (
a number instead) to the box rather than mention this technical detail. If you explore the details you can make that
number much smaller.
