Ok i got a kvm switch. When im in X and I switch to another computer, then back to X my mouse is frozen. My keyboard still works fine, so i just loged out of x and went back in. And my mouse worked. Why does it freeze when i use the switch, it works fine when im not in X???? I use slackware 9.0, and what im thinking is... if i could just run the gpm script after i switch back it be fine? right? but i dont know the script for gpm, so can someone please help me. Thanks.
I've seen similar problems when the XF86Config (or XF86Config-4) file has the wrong "Option Protocol" defined under the "InputDevice" section for the mouse. Post that setting from your XF86Config and also the make/model of your mouse.
I also have a kvm switch and had that problem. I press the scroll lock button twice (very fast) to switch to the other computer and after alot of trouble found that the scroll lock button somehow was basically locking up everything in linux. I just hit the button again and everything was fine.
If your using the same button try setting it to another button like F12.
Yeah, it's a common problem with KVMs, the other one you'll find is that the mouse will start to act funky after the 2nd time you've switched to the linux box. Try moving to a concole window ctrl+alt+F3 then back to your windowed environment, ctrl+alt+F7 to see if that fixes it ( it usually does for the funky mouse problem ), otherwise it's logging out/rebooting the windowed environment. Don't know why it happens, but it is annoying.
Most times I've seen this happen has been due to a KVM switch on its way out. When they start going bad, you'll start losing your mouse when you switch. Linux is usually more resilliant than Windows, which usually requires a reboot to get the mouse back.
I've used Belkins. I had one of their old boxy black ones, then I bought a newer more shapely one. It's done it on 2 port and 4 port switches. Supposedly, someone uses a different brand, that escapes me right now...and they've not had this problem.
I use a IOGear kvm swtich, set me back 50 dollars but was better than buying a second monitor. I never read the manual on the thing.. but I assume it emulates the keyboard and mouse cause when I start my computer up and switch over to it the mouse and keyboard works.
Out of curiosity.. Are the cables securely attached? And you obvisouly have another computer, does it do the same thing when swiching from linux to the other box?
