Windows Vista and KVM switch

Installed MS Vista U Beta 2 x64:

Has anyone noticed any problems with their KVM switch and Windows Vista's
power saving mode? If I let the monitor power down, I loose the monitor and
keyboard.

 

the KVM switch does not know the time of day, let alone which OS you are
using. They do have some video limits, but I have used two of them for years
without troubles. As for your 'sleep' problem, if it is setup correctly the
monitor and keyboard will power down normally. Check your bios as well as
Vista.

 

I was just mentioning the KVM swtich thing and the video power down seem to
be related. If Vista powers down the video here while connected to the KVM,
it won't wake up - the signal is lost - it usually not a problem with other
OS.

Thanks for the reply, though. I'm not sure how far I want to take this
particular investigation

 

Had the same problem on mine, but did not think the KVM switch had
anything to do with it as its just a load of wiring and a couple of
LEDs. I assumed my "won't wake up" problem was caused by something
related to the ancient keyboard I use on it, or if not something not
worth worrying about. I just fixed the power options to prevent Vista
from sleeping, problem cured.

I've never had a problem with my D-Link 4-port KVM, but then, I generally
turn off all power-saving features (like "Shut off monitor after XXX
minutes") in winblows, just because I usually don't need them.

I'm having this problem with Vista RTM and a Cables To Go KVM which works
just fine with two XP machines. I tried setting sleep and power down settings
off and still have the problem.

 

I suspect that the monitor detection is working too well. When I switch
away, Vista behaves like I just unplugged the monitor n a laptop it
switches to the internal screen and on a desktop it switches the display off.
Then I suspect the system is going into powersave correctly and switches to
the logon screen (user locked). From this mode, the system does not appear
to be able to detect when the monitor is back (presume it needs to be in user
mode to do that).

You can test this by switching kvm away for a few minutes then switching
back - the screen bumps around. switch away for longer than your powersave
timeout and it will not come back at all. The "secret" is getting out of
standby/sleep then being able to log on without seeing the screen to get back
into user mode - if I do this, the screen appears after a few seconds.

Just a guess.

I'm having this exact same problem (even on Vista32). I've turned off
all sleeping and power management features. When I switch away, even
for a moment, the display is just dead. Plugging the display directly
into the PC (removing it from the KVM switch) doesn't help either. The
display is just DEAD. The only thing I've found to do is to hit the
power down switch. And then power back up once the computer shuts
down. Obviously this is unacceptable.

Has anyone found a solution at all?

 

Same kind of problem here. Vista on my laptop. XP on my desktop. Both
running through a KVM. When I switch away from the laptop and then
switch back to it, it thinks I just attached a new monitor and it
switches the display to the laptop LCD momentarily and then back to the
CRT. Since the LCD is set at a lower resolution than my CRT, all my
icons, etc get rearranged and all my windows get squished so I have to
RESTORE and then MAXIMIZE them again to get them full screen. I just
bought a $200 powered KVM, figuring it would solve the problem (by
maintaining a connection to the VGA ports of all PCs regardless of
which PC was active), but it did not.

Does anyone have a clue as to how to get Vista to act like XP with
regard to display detection? This is a huge P.I.T.A.!

Thx.

My problem with a KVM is, XP on one,and Vista Ultimate on the other. If
I boot the 2 computers at the same time the only one which is visible is
the one that the KVM is switched to at the start. To get both computers
to show, I have to boot-up pc #1, then remove the DVI cable of pc #1
from the back of the KVM, then I boot-up pc #2. After that I reconnect
the DVI cable of pc #1 to the back of the KVM, and all is OK.

using an AMCONN (4port/dual monitor) - actually works fine with m
logitec wireless mouse/kbd - though I do seem to be pushing things wit
a powered keyboard (saitek illuminated) or the aluminum apple. Thi
thing us PS2 io with usb in the front. As for monitor - no problem wit
1680x1050 res squeezed out the dvi to std vga. Win XP had to prime i
with a ps2 kbd - the vista found it on its own. one thing and th
reason I posted - the video start up is flawless unattended and n
burping the dvi - graphic cards (nvidia gen 8/9) all see it fine and
am running 4 rigs with this set u
