全屏时 vncviewer 的滚动速度更快

全屏时 vncviewer 的滚动速度更快

我已经x11vnc在一台有两个屏幕的机器上启动了,并且正在使用vncviewer一台单屏幕机器来连接它。也就是说,本地窗口小于远程屏幕。在全屏模式 ( F8-> Fullcreen) 下,您可以将鼠标移动到屏幕边缘进行滚动。这对我来说非常慢(仅查看另一个屏幕就需要大约 20 秒左右)。

TightVNC 文档,有以下选项:

bumpScrollTimebumpScrollPixels
当处于全屏模式且 VNC 桌面大于 X 显示器时,只要鼠标触及屏幕边缘,就会发生滚动。滚动的最大速度为每 bumpScrollTime 毫秒 bumpScrollPixels 像素。当然,实际滚动速度会比这慢,这取决于您的机器有多快。默认为每 25 毫秒 20 像素。

这听起来像是我想要设置的选项,但对于vncviewerFedora21 中的当前版本(我认为还有许多其他发行版),TigerVNC 是一个TightVNC 的。如何才能使全屏滚动更快?也许我可以设置命令行中的选项~/.vnc/config或作为命令行的一部分。

更新:看起来相关,但我找不到任何可以解决问题的方法。

我找不到TigerVNC我通过 看到了文档man vncviewer,所以它在这里......

NAME
       vncviewer - VNC viewer for X

SYNOPSIS
       vncviewer [options] [host][:display#]
       vncviewer [options] [host][::port]
       vncviewer [options] -listen [port]

DESCRIPTION
       vncviewer is a viewer (client) for Virtual Network Computing.  This manual page documents version 4 for the X window system.

       If you run the viewer with no arguments it will prompt you for a VNC server to connect to.  Alternatively, specify the VNC server as an argument, e.g.:

              vncviewer snoopy:2

       where  'snoopy' is the name of the machine, and '2' is the display number of the VNC server on that machine.  Either the machine name or display number can be omitted.  So for example ":1" means
       display number 1 on the same machine, and "snoopy" means "snoopy:0" i.e. display 0 on machine "snoopy".

       If the VNC server is successfully contacted, you will be prompted for a password to authenticate you.  If the password is correct, a window will appear showing the desktop of the VNC server.


AUTOMATIC PROTOCOL SELECTION
       The viewer tests the speed of the connection to the server and chooses the encoding and pixel format (color level) appropriately.  This makes it much easier to use than previous  versions  where
       the user had to specify arcane command line arguments.

       The  viewer normally starts out assuming the link is slow, using the encoding with the best compression.  If it turns out that the link is fast enough it switches to an encoding which compresses
       less but is faster to generate, thus improving the interactive feel.

       The viewer normally starts in full-color mode, but switches to low-color mode if the bandwidth is insufficient. However, this only occurs when communicating with servers supporting protocol  3.8
       or newer, since many old servers does not support color mode changes safely.

       Automatic selection can be turned off by setting the AutoSelect parameter to false, or from the options dialog.


POPUP MENU
       The  viewer has a popup menu containing entries which perform various actions.  It is usually brought up by pressing F8, but this can be configured with the MenuKey parameter.  Actions which the
       popup menu can perform include:

         * switching in and out of full-screen mode

         * quitting the viewer

         * generating key events, e.g. sending ctrl-alt-del

         * accessing the options dialog and various other dialogs

       By default, key presses in the popup menu get sent to the VNC server and dismiss the popup.  So to get an F8 through to the VNC server simply press it twice.


FULL SCREEN MODE
       A full-screen mode is supported.  This is particularly useful when connecting to a remote screen which is the same size as your local one. If the remote screen is bigger, you can scroll by bump‐
       ing the mouse against the edge of the screen.

       Unfortunately this mode doesn't work completely with all window managers, since it breaks the X window management conventions.


OPTIONS (PARAMETERS)
       You  can  get a list of parameters by giving -h as a command-line option to vncviewer.  Parameters can be turned on with -param or off with -param=0.  Parameters which take a value can be speci‐
       fied as -param value.  Other valid forms are param=value -param=value --param=value.  Parameter names are case-insensitive.

       Many of the parameters can also be set graphically via the options dialog box.  This can be accessed from the popup menu or from the "Connection details" dialog box.


       -display Xdisplay
              Specifies the X display on which the VNC viewer window should appear.


       -geometry geometry
              Standard X position and sizing specification.


       -listen [port]
              Causes vncviewer to listen on the given port (default 5500) for reverse connections from a VNC server.  WinVNC supports reverse connections initiated  using  the  'Add  New  Client'  menu
              option or the '-connect' command-line option.  Xvnc supports reverse connections with a helper program called vncconfig.


       -passwd password-file, -PasswordFile password-file
              If you are on a filesystem which gives you access to the password file used by the server, you can specify it here to avoid typing it in.  It will usually be "~/.vnc/passwd".


       -DotWhenNoCursor
              Show the dot cursor when the server sends an invisible cursor.


       -PointerEventInterval
              Time in milliseconds to rate-limit successive pointer events.


       -ImprovedHextile
              Try harder to compress data (default).


       -QualityLevel level
              JPEG quality level (default is 8).


       -NoJPEG
              Disable lossy JPEG compression in Tight encoding.


       CompressLevel level
              Use specified compression level (default is 2).


       CustomCompressLevel level
              Use custom compression level. Default is CompressLevel is specified.


       -SendPrimary
              Send the primary selection and cut buffer to the server as well as the clipboard selection (default).


       -SendClipboard
              Send clipboard changes to the server (default).


       -AcceptClipboard
              Accept clipboard changes from the server (default).


       -Shared
              When  you make a connection to a VNC server, all other existing connections are normally closed.  This option requests that they be left open, allowing you to share the desktop with some‐
              one already using it.


       -ViewOnly
              Specifies that no keyboard or mouse events should be sent to the server.  Useful if you want to view a desktop without interfering; often needs to be combined with -Shared.


       -Maximize
              Maximize viewer window.


       -FullScreen
              Start in full-screen mode.


       -FullScreenAllMonitors
              Enable full screen over all monitors (default).


       -FullscreenSystemKeys
              Pass special keys directly to the server in full-screen mode.


       -RemoteResize
              Dynamically resize the remote desktop size as the size of the local client window changes (default).


       -DesktopSize widthxheight
              Instead of keeping the existing remote screen size, the client will attempt to switch to the specified since when connecting. If the server does not  support  the  SetDesktopSize  message
              then the screen will retain the original size.


       -AutoSelect
              Use automatic selection of encoding and pixel format (default is on).  Normally the viewer tests the speed of the connection to the server and chooses the encoding and pixel format appro‐
              priately.  Turn it off with -AutoSelect=0.


       -FullColor, -FullColour
              Tells the VNC server to send full-color pixels in the best format for this display.  This is default.


       -LowColorLevel, -LowColourLevel level
              Selects the reduced color level to use on slow links.  level can range from 0 to 2, 0 meaning 8 colors, 1 meaning 64 colors (the default), 2 meaning 256  colors.  Note  that  decision  if
              reduced color level is used is made by vncviewer. If you would like to force vncviewer to use reduced color level use -AutoSelect=0 parameter.


       -PreferredEncoding encoding
              This option specifies the preferred encoding to use from one of "Tight", "ZRLE", "hextile" or "raw".


       -UseLocalCursor
              Render the mouse cursor locally if the server supports it (default is on).  This can make the interactive performance feel much better over slow links.


       -WMDecorationWidth w, -WMDecorationHeight h
              The total width and height taken up by window manager decorations.  This is used to calculate the maximum size of the VNC viewer window.  Default is width 6, height 24.


       -log logname:dest:level
              Configures the debug log settings.  dest can currently be stderr or stdout, and level is between 0 and 100, 100 meaning most verbose output.  logname is usually * meaning all, but you can
              target a specific source file if you know the name of its "LogWriter".  Default is *:stderr:30.


       -MenuKey keysym-name
              This option specifies the key which brings up the popup menu.  The key is specified as an X11 keysym name (these  can  be  obtained  by  removing  the  XK_  prefix  from  the  entries  in
              "/usr/include/X11/keysymdef.h"  -  the  currently implemented list is: F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, Pause, Print, Scroll_Lock, Escape, Insert, Delete, Home, Page_Up,
              Page_Down).  Default is F8.


       -via gateway
              Automatically create encrypted TCP tunnel to the gateway machine before connection, connect to the host through that tunnel (TigerVNC-specific). By default, this option invokes SSH  local
              port  forwarding,  assuming that SSH client binary can be accessed as /usr/bin/ssh. Note that when using the -via option, the host machine name should be specified as known to the gateway
              machine, e.g.  "localhost" denotes the gateway, not the machine where  vncviewer  was  launched.  The  environment  variable  VNC_VIA_CMD  can  override  the  default  tunnel  command  of
              /usr/bin/ssh -f -L "$L":"$H":"$R" "$G" sleep 20.   The tunnel command is executed with the environment variables L, H, R, and G taken the values of the local port number, the remote host,
              the port number on the remote host, and the gateway machine respectively.


       -ZlibLevel level
              Zlib compression level.


       -x509crl file
              X509 CRL file


       -x509ca file
              X509 CA certificate


       -SecurityTypes types
              Specify which security scheme to use.

支持全屏模式。当连接到与本地屏幕大小相同的远程屏幕时,此功能特别有用。如果远程屏幕较大,您可以通过将鼠标触碰屏幕边缘来滚动。

但没有提到如何配置它。

如果开发人员看到这种情况,为什么不按照鼠标移过屏幕边缘的量来滚动,而不是以恒定的滚动速度滚动呢?
