Comment Re:This is a good thing (Score 3, Informative) 712

I was trying to put Linux on my desktop computer, but it doesn't support the wireless USB dongle I use. This was last weekend. The same dongle works perfectly in Windows.

I was trying to put Linux on my work computer, but it doesn't support my three monitor, two video card display out of the box. This was about a month ago.

I love Linux, and it's fun to use on computers that have supported hardware (I love it on my ASUS netbook), but if you don't have supported hardware, it's still a nightmare.

Comment Re:No PAE?! (Score 3, Insightful) 753

You mean some people still run a 32-bit OS?

Not only that, but apparently Windows cannot use PAE - Physical Address Extension to address more than 4GB (according to the WP entry, PAE is supported, but the 4GB limit is still enforced - due to some obscure licensing problems).

The problem is with virtual memory. A process still uses 32bit memory addresses to reference memory. This means that a process can still only address 4GB of memory. If you were to use more than 32bit memory addresses to get more memory, suddenly you aren't a 32-bit OS anymore.

PAE only helps the OS be able to manage more than 4GB of memory.

Comment Re:Its the compiler, stupid. (Score 5, Informative) 753

It is the compiler which is having ressource problems. The profile-guided optimiser needs more than 3GB to be able to do its optimisations. And apparently, the Windows its running on can't do PAE to use more than 3GB neither.

PAE allows 32-Bit computers to use more than 4GB of ram, but it doesn't allow Windows to assign more than 3GB to any single process.

Comment What's the point? (Score 1) 567

What's the point of the upgrade, or rather, what does it give me? I'm using Ubuntu 9.10 right now, and I've been installing the software and other updates as they come. What changes from one major version of Ubuntu to another? Obviously it's something more than just updated versions of all my software packages. What is it?
