We have a very large number of systems to test, and it is not feasible to test every system with both 32-bit & 64-bit. There are also requirements from the manufacturers to consider. (Please note, I don't perform the testing, so my knowledge is second hand.)
Personally, I'd rather see lots of 32-bit systems than a handful of 64-bit. :)
- wmf 15y agoWhy not test 64-bit first and only try 32-bit if it fails?
- schwuk 15y agoDesktops, Laptops and Netbooks are certified using the 32bit version of Ubuntu and Servers are certified using the 64bit version of Ubuntu Server Edition. This is based on the most common usage patterns we've seen. Another answer is that it would lengthen an already long process.
- GeneralMaximus 15y agoThat usage pattern only exists because 32-bit Ubuntu is selected by default and marked as "recommended" on your download page. People I know regularly download the 32-bit version even though I tell them to get the 64-bit version. Why is 64-bit not the recommended option?
- mappu 15y agoWhy should it be? PAE [1] is reported to work very well, so there's no RAM problem. Plus, things like ndiswrapper go a long way to highlighting Ubuntu's famous 'ease of use', and i imagine it's a huge hassle to get that working on x86_64. 64-bit is a higher number, but it's not instantly better in all situations. Larger pointers = effectively smaller cache, and the extra registers don't always make up for that. _________________ 1. https://help.ubuntu.com/community/EnablingPAE https://help.ubuntu.com/community/EnablingPAE
