How to start X into Gnome?

When I use command 'startx', I am brought into KDE .
But I prefer Gnome in MDK10.1 .
Who can tell me how to start X into Gnome with 'startx' ?
Any help will be appreciate, 3x!

startgnome

3x, but i mean how to loginto gnome before i start X ?
My system boots to console mode, not X , so you can not
run 'startgnome' directly.
I have a shabby method :
1. xinit
2. type startgnome in the little simple console window in X.
3. gnome starting...

well,somewhat disgusting
I need a simple way , just like type 'startx' to start gnome.
tnx again.


sorry for E text. my scim doesnot work again *(ctrl space no response)

我只知道一个办法，在控制中心的自动登录里面更改首选的桌面环境。但肯定这仅仅是一个配置文件的问题。

~/.desktop
我这边这个文件可以做到
