[03:29] <youDownWithIRC> hi all, i have installed lubuntu 19.10, into the emcc of an atomic pi.  I'm looking to change o.s.'s, and i want to back up the current installation onto a flash drive, so i can be able to reinstall it again.  There's a lot of information out there, and its confusing to know which is the best method for me
[03:30] <youDownWithIRC> so here is my question, whats the best way to backup a lubunbtu installation thats currently in the emcc of a computer, onto an external flash drive, to be able to 'restore it' later.  any help is appreciated
[04:45] <guiverc> youDownWithIRC, I don't know, I'd likely use `dd` to take a copy of the drive & save that, plus `rsync` all wanted files (if re-install is necessary so you can restore that on re-installed image).. I backup multiple ways usually to different locations in case some fail for some reason; but I have no experience with pi (except using rsync for wanted files)
[05:22] <youDownWithIRC> hello all.
[05:37] <tbs> hi
[06:06] <mmebsd> which is better between lubuntu and xubuntu
[06:06] <mmebsd> whihc one is more popular?
[06:13] <tbs> metbsd: u should search web for this question i guess
[06:14] <guiverc> metbsd, they each have strengths and weaknesses; your end-use case will dictate which is best for you.  Lubuntu is lighter, but use it certain ways and Xubuntu may be lighter for you (ie. your use case will dictate which best suits you)
[06:16] <tbs> i have 4 gb ram, with xfce if i remember right it uses %12 ram, with lubuntu it uses %11 ram at start. i would say lighter if it was %10 or less at least
[06:16] <metbsd> i just want a light weight gui os for old hardware
[06:16] <guiverc> metbsd, there are also differences between versions; XFCE as used by Xubuntu has moved from GTK2 to GTK3 which has had effects (noticable on older hardware more than newer), Lubuntu from LXQt (GTK2) to LXQt (Qt5)
[06:17] <metbsd> so gtk3 is lighter than qt5 right?
[06:17] <guiverc> In my experience GTK3 is heavier than GTK2; I felt Xubuntu slow down on really old hardware as it moved to GTK3
[06:18] <guiverc> though on this box I'm using now with more grunt, I really couldn't see a difference... it'll depend on your hardware.
[06:18] <guiverc> MATE also slowed down significantly switching from GTK2 to GTK3
[06:19] <tbs> i just came from xfce mint, i guess lubuntu and xfce mint s smilar about being light, the reason i left xfce is there s no option for arrange items at desktop
[06:19] <guiverc> LXQt is actually extremely light, I couldn't really spot a difference between it and LXDE (GTK2) - however the GTK2 to Qt5 makes differences necessary to remain light (effect would be lost possibly using GTK3 apps for example with limited RAM)
[06:22] <tbs> imo u should create bootable usb of xubuntu and lubuntu and see the differance, but i suggest u to use xfce mint if
[06:22] <tbs> if u want xfce desktop, cuz it configured better than xubuntu imo
[06:22] <tbs> but im not sure since i dont know much
[06:24] <guiverc> different versions have different software stacks - so need to be considered; the version of Xubuntu will say if all GTK3 (19.10) or only part GTK3 (parts GTK2) - really old versions running GTK2 only were lightest..  but even if nothing running - that's not the full picture for 'lightness' as libs used by desktop should match the libs needed for your apps to remain light.
[06:24]  * guiverc fyi:  versions of Xubuntu using GTK2 only are now all EOL
[06:26] <guiverc> metbsd, what age hardware?
[06:47] <metbsd> guiverc, it's pentium t series cpu. dual core
[06:47] <metbsd> it's garbage
[06:49] <guiverc> 2010 it looks like (or the t4500 I'm comparing to), you'll probably not notice the difference much with that; by OLD I was thinking older.. on that I'd probably worry about RAM usage more than cpu.
[06:51] <guiverc> fyi: the desktop I'm replying on is from 2009
[07:03] <guiverc> metbsd, I just noticed I have a lenovo thinkpad sl510 (c2d-t6570, 2gb ram, i915)  listed in my test machines; ; yeah it's slow..
[07:03] <metbsd> mine is like your cpu.
[07:04] <metbsd> what os do you suggest? i tried win7 it's pretty slow im expecting linux faster
[07:05] <guiverc> metbsd, consider your user preferences (xubuntu/lubuntu) & GUI you prefer, but also apps you want to use..   (if GTK3 apps, use Xubuntu, if Qt apps use modern Lubuntu, ... Lubuntu is lighter but the lightness can be lost with poor app choice)
[07:05] <metbsd> basically just a browser and movie player
[07:06] <metbsd> what's what my dad want
[07:08] <guiverc> on the sl510 I mentioned; Lubuntu is lighter & slightly faster, but difference is not huge.. thus GUI preference is an issue. If Lubuntu, which Lubuntu - LXDE (legacy) or LXQt (modern) - I like modern LXQt myself; but you'll need to upgrade to 20.04 before 19.10 reaches eol mid-2020.
 Why LXQT? Not XFCE?
 Why Lubuntu? Not Xubuntu?
 Coz lxqt is lighter
 @The_LoudSpeaker [Coz lxqt is lighter], When I boot OS into desktop and no running any program, ram usage of lxqt is lighter than xfce. … But I run several programs, the ram usage is increased less than lxqt, finally lxqt uses ram more than xfce about 20%-30%, I don't know why.
 That's because you are using gtk apps in lxqt. In xfce, gtk libraries, many gtk dependencies, etc are already loaded in ram hence you don't see a huge bump in usage. While you see more usage for same apps in lxqt. If you use qt apps with lxqt. I am sure you will get better results.
 Many apps provided with Lubuntu are qt apps. Libreoffice, Firefox, quassel, qttransmisson, etc.
 But Firefox on Xubuntu is gtk one.
 Same with libreoffice.
 @The_LoudSpeaker [That's because you are using gtk apps in lxqt. In xfce, gtk libraries, many gtk …], As long as I only use apps with qt that ram usage will be less than in xfce?
 Yup!
 @The_LoudSpeaker [Yup!], Thank You
 Welcome! :)
[18:53] <akemhp> So the default desktop of Lubuntu is LxQT?
[18:55] <akemhp> Also is it running OpenBox window manager at the same time? or is it only LxQT that does the window manager and desktop?
[19:21] <The_LoudSpeaker> yup! Default DE of Lubuntu is lxqt and openbox is the window manager.
[19:35] <akemhp> Ok, thanks The_LoudSpeaker :)
[19:36] <akemhp> I never heard about LXQT before LUbuntu, but it's nice, i guess it is pretty new maybe.
[19:36] <The_LoudSpeaker> Yup! It is new and currently under heavy development.
[19:37] <akemhp> It's good cause on fresh boot it takes only about 500 MB RAM on my old dual core desktop computer.
[19:37] <akemhp> Okay.
[19:37] <The_LoudSpeaker> Good to know.
[22:33] <wxl> i usually overwrite it with /dev/zero or /dev/null
[22:33] <wxl> err not /dev/null but /dev/urandom or /dev/random
[22:46] <wxl> if you want, or not
[22:50] <wxl> the `shred` command can simplify things
[22:54] <wxl> i would rather `dd` personally, but it's a little more dangerous/easier to screw up
[22:55] <wxl> you presumedly have GRUB in your MBR so if you remove the Lubuntu partition, you'll still be booting with GRUB
[22:55] <wxl> i'm not sure what GRUB will do if you remove its default partition
[23:02] <wxl> yes dd will work
[23:02] <wxl> and whether or not you have grub, you will have SOME sort of bootloader or another on a dual boot
