Ubuntu 14 memory needs

I'm installing Ubuntu on VirtualBox. The minimum system requirements for RAM of Ubuntu is 512MB. I'm reading that Linux uses memory much differently than Windows does, but I really don't know what that means.

I have 16GB of available memory if Windows 10 was not the host OS, so since Win 10 needs a minimum of I think 2GB of available memory, how much memory should I allow Linux Ubuntu? Should I go with a really big figure if I'm going to be using it often or is that overkill?

Also, I couldn't find anything regarding video memory for Ubuntu nor with Win 10, with system requirements. It simply says whatever, like 1366x768 recommended and directx and so on. I have about 768MB of video memory on my laptop, which is ridiculously low, but I'm not a gamer, so it's not a bother. The default setting for Ubuntu x64 on VirtualBox is actually 12MB for video memory. Is that sufficient? Or should I go higher? Thanks.
 
What specifically are you going to do on the vm?

That's like asking will a Chevy or a Ford win the downhill boxcar race.

4 GB should handle whatever you're doing.
 
Ubuntu 32 bit could run on 512 MB but for smooth performance I would recommend 1GB at a minimum if not 1.5 GB. What you have heard about the memory being different in Linux can go many ways. Yes the memory is handled slightly different but the main thing is Windows started using over 1GB of memory when they released 64 bit, depending on desktop choice Linux 64 Bit systems can use less then 256 MB of ram. Also I would recommend something like Ubuntu MATE or Xubuntu for virtualization. Unity which is the default desktop is graphically heavy. Canonical is currently rewriting Unity in QT from the ground up and when it launches with Unity 8 that will fix that issue but in the mean time go with what I recommend. For the amount of video memory to dedicate to your VM I always do about 50 MB which has always been fine for me.
 
Thanks, that's awesome) @beers Sry it took so long for me to respond. Had lost my cf password for quite some time & i didn't want to get a new one.

I actually ended up secure erasing the Windows 10 drive & doing a full boot of Ubuntu 14.04 LTS. Looked great too.

But, i should have done some more "homework", cuz i didn't think my WiFi, Ethernet, & Bluetooth drivers wouldn't work w/ Linux.

Seems everyone was having the same issue with my same network card driver. I think these are them, at least for Windows 8.1 cuz Win 10 isn't supported on the HP site, even though it works:

  • Mediatek 802.11 Wireless LAN Adapter Driver 11.0.748.2
  • Realtek Local Area Network (LAN) Driver 5.0.37.0
  • Mediatek (Ralink) Bluetooth Software Driver 8.18.621.2013

I realize Linux installs & security go together much better when the former are done via the CLI & not the web. I've always like feeling secure, but now more so, after a jag from Kansas, or a proxy there, hacked my phone & installed restart, crash, & freeze scripts on my android phone :eek: {I was so ticked that I actually talked to two pro-bono attorneys to sue them for damages before I realized it was just a waste of time. I got no respect for this kind of stuff when i never mess w/ people first].

@DMGrier and @beers I'm really digging Linux & enjoying learning the CLI - I never had the patience w/ it previously. I have many questions, but I'll just address a few here:

1. Was Ubuntu 14.04 LTS smth i purchased? I chose the amount of money I'd be paying. If a purchase, then should i:

A. Manually update the wifi, ethernet, & BT drivers? (still learning the commands)

B. Manually update the kernel? (still learning commands) o_O

2. Is it all donation-based? If just a donation & i won't lose possible 3-year support, should i:

A. Update the whole OS? (i have no files that i've saved on my drive, so it's not problem).

B. Other option? :confused:

[My pc i'll be using Ubuntu on: HP Pavilion m6-k022dx]
 
Any Ubuntu 'purchase' is a donation. The OS is offered at no cost.

LTS is simply the version that they choose to update over a long period of time. If you just run a normal desktop then there's no issue updating to 15.10. Most of the LTS keep the same kernel tree (but add patches) for maximum compatibility for the lifetime of the distro.

Which specific Mediatek device is it? There's a download list here:

Thanks. Not sure what I did differently last time. Maybe I looked up HP network drivers for Windows 8.1 and the drivers listed were the possibilities I thought it was.

I went to the same drivers page for my machine and put in Windows 10 this time, and the only result that came up was:

Realtek Local Area Network (LAN) Driver
8.18.621.2013

But if I were to download that, still would only install on a Windows OS. How do I get that same driver for Linux?

I just dL'd the most recent Ubuntu version. I'm gonna try that. Maybe everything will "fix itself." If not, I'll most definitely be back :eek:
