Hi,

I have two linux Test machine, runnign Cent OS 3.6, Both machine user KEyboard, Mouse and Monitor through single sharer i.e. both CPU use same Stuff, I just need to pressa button to switch my physical machine.

Every thing is working fine for my 2 months with same hardware, I have these machine for testing and I Reinstall them randomly.

but yesterday I reneed to replug my sharer thanks to little shifting of my desk. Since than I am facing problem with my keyboard.

I am able to enter my Login information on screen but I cannot use keyboard once I am on KDE desktop on either machine. Can anyone please help me find out the reason, my both machine are dump until I format them, and I cannot do taht as my Backup is not ready with me...
Help me making them running...

Thanks though I can SSH one of them , don't know why other one is not giving my login it was doing that till yesterday....

Thanks

well

are you using a KVM switch

I do not see any reason why you should face any problem with that w.r.t to Linux

Hi,

Great magician you are ..

Yes I am using KVM switch and I wasn't facing problem until I re connect that to my system, actually I have to switch my Table and got new one. Since that I am facing this problem...
I am notsure why..
But I can use Keyboard to enter Login information but when I get my desktop or even Command line, than I am unable to use keyboard...

If I can enter login info , hardware engineer says that mean hardware is working with system..

and To good keyboard does the same for Both PCs

Help me

Hi there

Just try this

Plug in the key board directly into the system,and see if it is working fine for you.

I remember some time back I too had some issues with KVM switches and I ended up replacing those ..

Hi,

I eventually format as I take my backup through SSH. Seems the keyboard wire change to me and thats cause the problem. One more interesting thing is that before I format my PC. One of System give access to keyboard when I just kept it for while without doing any thing....

Anyways Thanks for your Help

could not get you there on the last line...

Hi,

Well I think I didn't word that properly...

actually I got frustrate with keyboard not working, since I can ssh to my Linux box, I kept the linux machine running and Use another machine to SSH and work on it. But After 4-5 hours I try to recheck the keyboard and it was working fine, though it doesn't work immediately after Boot up.

Seems some hardware failure to me..
I didn't like these KVM switcher they are Good looking but worth a Dustbin only

Well these KVM switches are costly in India

Good quality KVM switches are more costly

I am not sure but there are good quality KVM switches available by Linksys

Hi,

thanks for info. I will make my hardware department to change these switches.. )

They are good for nothing, and because of them I waste my two days figuring out the problem....

Anyways...Thanks for your guidance, it seems you have lot of knowledge of computer hardware. I will keep bugging you if I had any problem in future
