Description rjb 2000-08-10 09:16:56 UTC

Using a BELKIN Omni Cube 4-port keyboard/mouse/monitor switcher on a 
redhat linux machine with Xfree86-Mach64-3.3.6-20 X server.  Switching to 
and from the linux machine can sometimes (quite frequently) hang the X 
server.

The linux console drivers are not affected.  Windows machines are not 
affected.  The problem only appears to affect X servers.  This problem 
reduces the effectiveness of linux machines as servers since a single 
operator station cannot be used to manage many linux servers as it can 
with many windows servers.

Is this keyboard switcher mechanical or electronic?  Ie: Does it have
a power cable or power adaptor?  Are the keyboards standard AT style or
PS/2?  Are the mice serial or PS/2?  Any additional info you can provide
may help to pinpoint the problem?  What version of XFree86 are you using?
Please indicate the exact Red Hat package name/version/release if you can.

The keyboard switcher is powered.  All devices are PS/2.  The keyboard
switcher also intercepts the keyboard in some way.  <scrlk><scrlk><digit> can 
be used to switch between computers.

Please try the latest version of XFree86 from:

ftp://people.redhat.com/mharris/xfree86

Does it fix the problem?  If not, then it is a problem intrinsic to
XFree86 in general, and you should contact the XFree86 team about a possible
fix.  bugs

I do not have such a switcher to test with, although I have used
a switchbox before that worked fine (mechanical).

Closing bug due to lack of feedback.
