|
|
1. Why doesn't ctrl+alt+del work on secondary screens?
|
|
|
|
Synergy isn't able to capture ctrl+alt+del on PC compatible
|
|
systems because it's handled completely differently than
|
|
other keystrokes. If you need to use ctrl+alt+del you'll
|
|
have to keep your other keyboards handy just for that.
|
|
Future versions may add support for or some equivalent to
|
|
ctrl+alt+del.
|
|
|
|
2. Can the server and client be on different operating systems?
|
|
|
|
Yes. The synergy network protocol is platform neutral so
|
|
synergy doesn't care what operating systems are running on
|
|
the server and clients.
|
|
|
|
3. What's the difference between synergy and x2x, x2vnc, etc?
|
|
|
|
Unlike x2x, synergy supports any number of computers and
|
|
it doesn't require X on Microsoft Windows platforms. It
|
|
also has more advanced clipboard support and synchronizes
|
|
screensavers. x2vnc is also limited to two computers,
|
|
requires the separate vnc package, and is really only
|
|
appropriate for using an X system to control a non-X system.
|
|
However, the right tool for the job is whatever tool works
|
|
best for you.
|
|
|
|
4. What does "Cannot initialize hook library" mean?
|
|
|
|
This error can occur on a synergy server running on a
|
|
Microsoft Windows operating system. It means that synergy
|
|
is already running or possibly was not shut down properly.
|
|
If it's running then first end the synergy task. If it's
|
|
not then try logging off and back on or rebooting then
|
|
starting synergy again.
|
|
|
|
5. What security/encryption does synergy provide?
|
|
|
|
None. Synergy currently does no encryption or authentication.
|
|
Given that, synergy should not be used on or over any untrusted
|
|
network, especially the Internet. It's generally fine for home
|
|
networks. Future versions will provide encryption and
|
|
authentication.
|
|
|
|
6. What should I call my screens in the configuration?
|
|
|
|
You can use any unique name in the configuration file for each
|
|
screen but it's easiest to use the hostname of the computer.
|
|
That's the computer name not including the domain. For example,
|
|
a computer with the fully qualified domain name `xyz.foo.com' has
|
|
the hostname `xyz'. There should also be an alias for `xyz' to
|
|
`xyz.foo.com'. If you don't use the computer's hostname, you
|
|
have to tell synergy the name of the screen using a command line
|
|
option, or the startup dialog on Windows.
|
|
|
|
7. Why do my CapsLock and NumLock keys act funny?
|
|
|
|
Some systems treat the Caps-Lock and Num-Lock keys differently
|
|
than all the others. Whereas most keys report going down when
|
|
physically pressed and going up when physically released, the
|
|
Caps-Lock and Num-Lock keys report going down when being
|
|
activated and going up when being deactivated. That is, when
|
|
you press and release, say, Caps-Lock to activate it, it only
|
|
reports going down, and when you press and release to deactivate
|
|
it, it only reports going up. This confuses synergy.
|
|
|
|
You can solve the problem by changing your configuration file.
|
|
In the screens section, following each screen that has the
|
|
problem, add either or both of these lines as appropriate:
|
|
|
|
halfDuplexCapsLock = true
|
|
halfDuplexNumLock = true
|
|
|
|
Then restart synergy on the server.
|
|
|
|
8. Can synergy share the display in addition to the mouse and keyboard?
|
|
|
|
No. Synergy is a KM solution not a KVM (keyboard, video, mouse)
|
|
solution. However, future versions will probably support KVM.
|
|
Hopefully, this will make synergy suitable for managing large
|
|
numbers of headless servers.
|
|
|
|
9. Can synergy do drag and drop between computers?
|
|
|
|
No. That's a very cool idea and it'll be explored. However, it's
|
|
also clearly difficult and may take a long time to implement.
|
|
|
|
10. Does AltGr/Mode-Switch work?
|
|
|
|
Sort of. Synergy sends the character you're trying to create from
|
|
the server to the client. If the client can figure out how to
|
|
create that character then it will do so, synthesizing whatever
|
|
key events necessary. However, operating system differences can
|
|
cause unexpected problems. Pressing either Ctrl key plus the left
|
|
Alt key on Microsoft Windows means AltGr but on Unix that just
|
|
means Ctrl and Alt are down. If you have a synergy server running
|
|
on Windows and are having trouble with Ctrl+Alt_L = AltGr, try using
|
|
the right Alt key as AltGr instead.
|
|
|
|
11. Why isn't synergy ported to platform X?
|
|
|
|
Probably because the developers don't have access to platform X
|
|
and/or are unfamiliar with development on X. Also, synergy has
|
|
inherently non-portable aspects so there's a not insignificant
|
|
effort involved in porting.
