Problem with fedora 11 when upgrade my fedora10
 

Hello.
I've got a problem with the upgrade when I use a cd to upgrade fedora 10 to fedora 11.
Yesterday I've maneged to download fedora11 and store it in a cd, choose 1、Install or upgrade an existing system.all done successfully, but, after I reboot the system, Instead to switching to the login screen, the screen remains :

Input: ImExPS/2 Generic Explorer Mouse as /devices/platform/i8042/serio1/input4
_




just remaining like this.Help me,I have my important documents in computer and cann't reinstall the system.

Unplug your mouse and use it in a text environment, see if it boots that way, or gives you a further error.

If it doesn't, the mouse/ PS2 driver needs updating, if it does then its a further problem

I unplug the mouse, the word disappear,thank you. but,screen still remains the following:

_
what's the problem? and how to update the mouse/ PS2 driver?

To be honest, I'm unsure; PS/2 ought to work right out of the box, its pretty much standard. Try a dbus update, that looks like thats where the problem is coming from

no matter what I input throw the keyboard,no use.

Right, lets do this the way I should have done it in the first place; some system details please

dbus update is too hard for me, system details, eh,its fedora,and I mostly not use text environment

No, I mean the system it's self; laptop, desktop, sever. Processor speed, RAM, Mouse type.

System Details

the fist screen shows:
desktop,Processor AMD Athlon(tm)64*2 dual 4000+ memory DDR2667 single channel 64bit
I cann't see the Mouse type.

Well you're sitting in front of the thing, what kind of mouse do you have?

EDIT: As in, does it connect via PS/2? USB?

I use my classmate's pc,mine is desktop and I have use linux since fedora 9 but I don't konw much.the Mouse type is probably ps/2

I want to ask one thing,whether can I use my fedora10disk to upgrade my now fedora 11 to 10?or how to use the "Rescue installed system " to copy and save my data?

As in a downgrade? If you want to do that, get your data off and reinstall, easiest way

I think downgrade is bad way,and probably it won"t work, my system refuses to log in and I didn't konw why this problem appeares,the fedora11 should be better than fedora 10 but the new problem make me helpless. unplug the mouse is right the solution to the question,but another question-remaing"_",no word-comes up,it's really boring.

Boring? See, to me, this is a puzzle, and puzzles are always good for beating boredom. Installations go wrong for many different reasons all the time. Back your data up and try a fresh install, with the mouse plugged in of course.
