Hi everyone,
I’ve just discovered this community and really like the content — thank you! 
I’m new to Linux but comfortable on Windows with OS installs, tweaks, repairs, and virus removal. I’m switching to Linux mainly for better privacy and security — I’m tired of Big Brother watching.
I’m using a 14-year-old Alienware M14x R2 that has served me very well. Here are the specs:
CPU: Intel Core i7 (3rd gen)
GPU: NVIDIA discrete graphics + Intel integrated graphics
Storage: 960 GB Kingston SA400S3 SSD + 256 GB secondary SSD
RAM: 16 GB physical
BIOS: Version A16
I’ve attached photos for reference.
My main questions:
I was hoping to install Qubes OS for its strong security-by-compartmentalization approach. However, I’ve heard about two potential issues:
The NVIDIA discrete GPU — most advice suggests disabling it in the BIOS and using only Intel integrated graphics.
VT-d / IOMMU — I may need to unlock the BIOS (A16) to properly enable VT-d for better virtualization support.
I’ve also been recommended Fedora Workstation or Linux Mint Cinnamon.
My top priorities are security and privacy/anonymity. I’d prefer a Linux distribution that supports strong containerization or compartmentalization (I noticed Fedora CoreOS and Qubes). The machine will be used for digital art, SFX work, and running a Windows 7 SP1 Ultimate virtual machine (I have many older programs that no longer work well on newer Windows versions).
Additional question: For privacy and anonymity, which would be better between Fedora, Linux Mint, and Debian (or their variants)?
I’d be extremely grateful for any advice on choosing the right distro and whether Qubes OS is realistically feasible on this old Alienware.
Thank you very much in advance!
You don’t get 3d acceleration with qubes, so it wouldn’t be great for sfx. That hardware might be too old to be compatible with qubes, but the installer will tell you.
Theres also Fedora Secureblue, but some of the packages you need might not work well with it, and anything outside of flatpaks has a special installation procedure. Libvirt works with it, you just need to do it all as root. Which isn’t ideal.
Thinking of your sfx job, a normal linux desktop with a lot of vms is probably your best bet for now. A macbook, also with a lot of VMs, might be better. Just don’t use icloud for anything.
For now, I’d just run a normal linux desktop like Fedora or Ubuntu, with virt-manager, a lot of VMs, and the kvm version of whonix, Whonix for KVM
Play with other linux distros in vms with nesting enabled if you want to run vms in them to see how that works and try something else.
If its feasible, use your phone for keeping passwords. Its probably more secure than any non qubes desktop.
First check vt-d functionality… It is important to qubes security model.
There isn’t a huge difference between fedora and ubuntu/debian, qubes is in a class mostly of its own. I prefer fedora for the more frequent updates. Fedora is also the os for most of qubes’ default qubes so knowing it is helpful
