独立显卡,你在哪里?

那个谁答应给我换一块独立显卡的,好兴奋。
先查看了一下Ubuntu都支持哪些显卡(https://wiki.ubuntu.com/HardwareSupportComponentsVideoCards)
再打开DELL的说明书一看,我的主板居然没有AGP插槽,只有三条PCI插槽,而且是Bus Speed为33 MHZ的老式PCI插槽,看了看网上大部分都是AGP,PCI-E接口的显卡,都没有这种插槽的显卡卖了,晕~~
PCI Express slots are much shorter than PCI slots and run at a higher speed: PCI is 32-bit and runs at 33MHz, whereas PCIe can run from 66MHz to 133MHz and is 64-bit. It is also a point-to-point connection, versus a shared bus.
PCIe can have multiple "lanes" which can be put to together to increase speed; these are known as x1, x2, x4, x8, x12, x16, and x32 links. Each lane can handle 2.5Gbps in each direction, while PCI is limited to 33MHz x 32bits = 1.066Gbps.
在淘宝上看到有GF2 Force MX 400一类的二手PCI显卡卖,很兴奋,但是又一看DELL的说明书,居然没法Disable集成显卡(BIOS里面的Primary Video Controller只有AUTO和ON两个选项,居然连DISABLE都没有),有点失望了....
只能期待今晚能通过实践找到办法了~
