Why is 64 bit Ubuntu not recomended for daily usage?
I am just in the process of setting up a new laptop which came with Windows 7 64 bit installed. I am going to set it up to dual boot Windows 7 and Ubuntu. When I went to get the Ubuntu download I noticed that the 64 bit version is labelled with
Not recomended for daily desktop usageNot recomended for daily desktop usage
Why would this be? Why is 64 bit Ubuntu not recommended for daily desktop usage?
Solution 1:
A big problem with 64bit on Linux is the Flash Player. There's a beta plugin for 64bit, but it does not get security updates, so you either needs to use a 32bit-plugin (+32bit-plugin-wrapper) or you have to use the unsecure version.
However, I'm using 64bit Linux and have no problems. (My distro is Gentoo, but I think Ubuntu should also run quite stable.)
Solution 2:
There's also the simple fact that if you ask a normal user whether they have a 32bit or 64bit CPU, they will look at you like you sprouted Zaphod Beeblebrox's second head. This way, only users advanced enough to know whether they have a 64bit-capable machine will download it. Otherwise, normal users might go "oooh 64, it must be better!" regardless whether they have the hardware.
Solution 3:
Using 64-bit Ubuntu 10.04 LTS. No problems here.
Solution 4:
I had to double check since I don't recall seeing that warning before. I've been using the 64 bit desktop Ubuntu for a couple years now and have not had problems other than the above mentioned Flash Player warning (Flash works for me but YMMV). I'm on 10.4 LTS with several machines and they're all stable.
Lack of drivers for your latest gadget might be a problem with 64 bit, but with 32 bit version of ANY OS you give up any use of memory beyond about 3 GB. That was the decider for me since I need the extra RAM to run VirtualBox and other programs.
Solution 5:
Main reasons:
- Giving the choice is disorienting for a lot of user
- 32 Bit works on all machine.
- 64 bit use more RAM and more power.
- A very few programs use more than 4Gb
So 64bit is bit faster but the big majority of user surf and check their email and don't care about CPU hit but are going to cry if the batteries life is cut by 30min.
In the past, Flash was kind of buggy on 64bit but this is no longer true. Adobe finnaly release a 64 bit version of their plugin http://arstechnica.com/web/news/2011/07/first-flash-11-beta-brings-64-bit-support-to-linux-finally.ars.
