Is there a list or repository which I can refer to so I can see the options of laptop brands or models which are safe to buy?
One day, when I can afford it, I'll buy a system76 laptop.
Be cautious when considering a Samsung. (see here: Linux blamed for Samsung laptop deaths)
If you plan on also using Windows, it's much easier and safer to install Ubuntu along-side Windows 7. Some people have experienced issues installing dual-boot along with Windows 8.
ASUS, HP, and Dell have released models with an Ubuntu OS option:
I believe Dell has Ubuntu pre-installed on other models as an option but there is no option to opt-out of windows unless you buy the XPS. Dell linux laptops.
According to Canonical:
Canonical works closely with Lenovo to certify Ubuntu on a range of their hardware.
A lot of developers see value in Lenovo Thinkpads for four main reasons:
- Trackpoint Functionality.
- Business Aesthetic.
- Road Warrior (Durable, good battery life).
- Comfortable keyboard.
In my experience Acer laptops run it pretty well, though there is a list of compatible computers that run perfectly with it on Ubuntu Certified hardware webpage.
system76 has it installed by default, but have varying tech support success and helpfulness.
Overall, if you have some time you can run it on pretty much anything.
