Recently I have installed Linux Ubuntu on my mom’s computer, replacing the old Windows XP. Seems enough for googling and mailing that she is doing. BTW, it works just fine after few small tweaks, like getting rid of too-fresh Unity interface and disabling awful overlay scrollbars (that appear only when you mouse over the edge of a window). Anyway, in the process, I had to read some information about Ubuntu and one of the questions was – whether to install 32-bit or 64-bit one. Jumping to the end – I installed 32-bit, to exclude any possibility of applications/drivers incompatibility (search it and you will see many problems with 64-bit Linux installations, old ones and new ones). In the process, I came to the Wiki page, explaining the difference. The thing that I did not understand is the strange claim “As Ubuntu is entirely open source, […] all hardware supported by Ubuntu works equally well in 32-bit and 64-bit environments”. Please someone explain me how the “open source” is connected to ability to “work well” in 64-bit system? For those who do not believe (and I wouldn’t myself if I heard that), here is a screenshot:
