I'm a long time Ubuntu user, and I'm now considering about buying a new laptop only for Ubuntu. But I arrived at serious question, and I'm really curious about what makes some computer compatible to Ubuntu or not.
For example, my latest Samsung laptop was terrible with Ubuntu, like,,, I cannot adjust the brightness and screen blinkering every time, and I thought it's because Samsung has modified their BIOS for Windows. But not sure.
So, my question is, is there a some kind of standard in computer industry so that computers manufactured not concerning about this standard doesn't work with Ubuntu? Or each computer components (like Wireless adapter, BIOS, Chipset etc.) decides will the computer compatible with Ubuntu?
I'm asking you this because I know I could find if some laptop compatible in Ubuntu Certified or Ubuntu Friendly etc., but if I could determine some laptops not in this list will also cause no problem with Ubuntu (now and in future releases).
( And I don't want shopping recommendations ;) )
Thank you very much! :)
