KVM switch and X

X freaks out when I use KVM switch
First off, I am a newbie. I am running Red Hat 7.2. I have X working OK, except when I switch my KVM to another PC, and back, the Gnome interface goes whacky. Mouse moves erratically, Keyboard might work, might not. It's a good, powered KVM, but the only way to reset it to telnet in and halt the system. ( I don't know how to get a list of running process' so I can kill just the X session). Any help?

It's an EdiMax. I can power up each of my computers without them being selected, so it does allow detection of the mouse. I have a Windows 2000 Server, Windows 2000 Professional, Redhat 7.2, and Windows 98, and the only quirk I get is with the RedHat. Even on the terminal session, if I change off of it to another and come back to the Linux box, I can't use the mouse to select and copy stuff. Do you know the command I can use to find the process id's so I can kill the X session from another terminal? Really getting interrested in Windows 2000/Linux integration, but having to halt the system to reset the X window is getting a little tedius. I even upgraded from 7.0 to 7.2 hoping to get rid of this glitch. Bill

I did some searching thru Linux newsgroups on google ([url=http://groups.google.com]groups.google.com[/url]) and someone mentioned hitting ctrl-alt-F1 to get a text console and then hitting ctrl-alt-F7 to go back to X. Supposedly, it will reinitialize the mouse when you do this. However, your original post said that the keyboard sometimes doesn't work when you switch either.

Excellent, both of these fixes worked. I knew about <ctrl><alt><f1>, but didn't realize <ctrl><alt><f7> would bring me back. Also the <ctrl><alt><Backspace> worked great. Thanks for the help, I'm taking the rest of the week off to geek (or get familiar) with my Linux box. Aside from this site, are there some other good beginners sites for Red Hat? I'm network proficient, but not X and not UNIX. I have lately had to integrate some UNIX boxes with Windows 2000 networks I'm implementing, and have been impressed with some of the things I have seen. Also, is there a freeware X Client I can run on my Windows PC's?, I think I will start another thread for that question, but I appreciate the help.

I have a Belkin SOHO 4 port KVM switch. With Redhat 9, I changed /etc/XF86Config as follows: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "Auto" Option "CorePointer" Option "SendCoreEvents" "true" Option "Device" "/dev/mouse" Option "ZAxisMapping" "4 5" Option "Buttons" "3" EndSection This solved the problem for me.

I would look into some Rose Electronics KVM switches.Our KVM Solutions are truly Multi platform and Multi O/S and have solved the mouse emulation problems. In some of our higher end KVM's we have firmware upgrades so we can virtually support any setup.
