KVM out of box support for Linux

By Jaqui ·
I have just bought a Startech SV411k KVM switch and it functions perfectly out of the box with linux.
[ so far as I have seen yet ]

the keyboard and mouse jacks are both ps2
video is svga

the switching is a button on the box or through the keyboard*

but since this is something raised fairly often as an issue, I figured that making sure it was out that this particular one works with linux can help those looking to get a kvm.

* I haven't bothered with the keyboard switching, one button on the box is faster than 3 to 6 keystrokes.

Another good one for Linux: Linksys SVIEW04

I've been using the Linksys SVIEW04 KVM with Linux and Windows for several years without any problems. Plug it in and it works. This one supports 4 computers, PS/2 ports, and large monitor VGA (I use 1280x1024). Recommended.

All KVMs will work with all OS out of the box with the one exception

you often need extra softwrae to make it work from the keyboard and not the buttons. The system and the buttons is hardware level and independent of the OS. But the keyboard activation is an OS level issue.

I always use the bttons as they're easier and quicker.

the nice thing about the startech

it's a keystroke sequence control rather than software on the pc control

{1] { not munpad 1 but keyboard 1 }
to switch to the first pc.
change the number to get to the other three systems. 1,2,3,4

the sequence is odd enough to not be a miskey likely sequence, so it shouldn't interfere with any softwre, and because the kvm itelf has the software for the keyboard control it's os independant.

I know I shouldn't be, but I have a fairly permanent bias against KVM's that use a double ctrl to active that KVm command mode. Goes back to the doom days (ctrl was the Fire key. Don't know how many times I got killed because of that)

This was my expectation and experience also. After all, it is a hardware device. But you never know.

Perhaps Jaqui can clear this up. What is the compatibility problem between KVMs and Linux? Is it just the issue mentioned Ernest mentioned or is it more than that?

a common complaint from people new to linux that their kvm doesn't work.
most likely because their kvm is wintel driven only, I just figured by posting a consumer model kvm that does work with it, we'll have a record that can be pointed to that shows what features to look for in buying one.

I had problems with one of the early raritan 4 port USB models (don't remember the model, sorry). They claimed it was because I wasn't using one of the 10 approved keyboards on their HW compatibiliy list, none of which were even available at Staples, Best Buy or CDW. It worked fine with Windows, but not with Linux. There was no software to install, so that was not a factor.

Actually, if anyone has a good recommendation on a USB based KVM, I'd love to hear it. I am using a little belkin 2-port with now,and it works okay, but every now and again it freaks out. Then I have to reach around and unplug it from the two attached computers to power cycle it.

I'm using a Belkin 4 port Omniview and it works

by Deadly Ernest In reply to Afraid not...

fine, the boxes a re a mix of Linux and Windows - USB, music and VGA. The only trouble I've had is that one of the wireless keyboard mouse sets would not work - however that set required manuf drivers to work on any OS. I found the KVMs work best with corded mouse and keyboard.

I did have a problem with an earlier KVM, sitecom 4 port - PS2 and VGA. You had to have the box selected before it was turned on and into the OS befor you moved away from it. Also if you had to turn off from that box before you shut it down, or the mouse and keyboard would close down until you restarted that box. I think it was to do with the way it managed the PS2 links.

You don't by chance have the Model handy do you?

Thanks again.

Looking at it says F1DS104U

It looks kind of surrealistic, but is neat.
