What does that mean? Latest Linux version also manage the card's virtual memory. No it doesn't. Driver manages the video card memory. On a 4GB card you can make a single 4gb allocation and when the memory runs out it runs out, allocation fails. No memory goes in and out of the card without explicitly asking the driver to do so. With Windows 7 the video driver does not see the video card memory. Windows implements a swap on the video card and swaps video memory in and out to system memory behind your back. You can over commit the card. Maximum allocation is ~1gb even when the card has 4gb, if you use too much memory performance drops suddenly. General graphic performance can be half that of Windows XP in some situations and when swapping performance can drop to under 10% of the full performance. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
virtualbox question
I installed gentoo in virtualbox. My problem is that with the livecd it builds a filesystem partition that is very small and I don't have control on the size. If I want to add stuff there, the space is very limited. 119mb for /. If I want to add modules to the kernel they need to sit under / , kernel compilation same thing. the /usr/src/linux is 330mb. So kernel recompilation is out of question because it will fail with no space left. Is there any way to increase the size of / ? or other solutions? I am opened to new ideas. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

It's been a while since I used Gentoo livecd, but what you describe sounds very strange. If there is a small partition created by Gentoo install process, it's going to be /boot, which is meant only to store kernels and grub stuff. If for some reason you really ended up with such a small / on hard drive, you can always boot off of the live CD again, and use parted to resize it. In general, if you want to get a real feel for what Gentoo is like, you are better off getting minimal install CD, and following the handbook. P.S. How is this VirtualBox question? P.P.S If you want to talk about Gentoo in real-time, I can often be found on #gentoo-he on irc.freenode.net. -- Ilya A.

I noticed that Israel was simply not included in the survey. This does not mean that he situation here is terrible or excellent, just that the folks at Georgia Tech did not manage to find data that would be suitable for inclusion, comparable, etc. It is not even clear how hard they tried - they could have decided that 75 countries presented a good enough sample. -- Oleg Goldshmidt | p...@goldshmidt.org ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
