First off, depth 24 at 24bpp (bpp=bits-per-pixel) is fairly uncommon and can cause problems in general. You might want to switch to 32bpp (for XFree86 see the “-fbbpp 32”, DefaultFbBpp, FbBpp and related options. ) Perhaps you have 24bpp because the video memory of the machine is low and the screen wouldn’t fit in video RAM at 32bpp. You should reconfigure it to use 32bpp or 16bpp. Recently (2012) it seems that some Xen virtual system setups have the X server running at 24bpp. It also can be slower than depth 24 at 32bpp. For this case depth 16 at 16bpp might be an acceptable option.

The creation of both tunnels can be automated. As of Oct/2007 the -ssh x11vnc option is available and so only this command needs to be run on the VNC Server side: x11vnc -ssh [email protected] (the SSH passphrase may need to be supplied.

The first is called ‘One time only’ meaning you just need to do it quickly once and don’t want to repeat; and the second is called ‘Continuously’ meaning you want the access to be available after every reboot and after every desktop logout. We describe two scenarios here. One time only:   If the X login screen is running and you just want to connect to it once (i.

It is not a matter of free memory, but rather free shared memory (shm) slots, also known as shm segments. This often occurs on a public Solaris machine using the default of only 100 slots. X11vnc tries hard to release its slots, but it, and other programs, are not always able to (e. You (or the owner or root) can clean them out with ipcrm(1).

Alternatively, the -clear_mods option and -clear_keys option can be used to release pressed keys at startup and exit. Tapping the stuck key (either via a new x11vnc or at the physical console) will release it from the stuck state. If the keyboard seems to be acting strangely it is often fixed by tapping Ctrl, Shift, and Alt. The option -clear_all will also try to unset Caps_Lock, Num_Lock, etc. Potential Gotcha: If somehow your Keypress of Ctrl-C went through x11vnc to the Xserver that then delivered it to x11vnc it is possible one or both of the Ctrl or C keys will be left stuck in the pressed down state in the Xserver.

However for TightVNC the changed setting only applies for NEW clients, current clients retain their TightVNC file transfer ability. If you want to switch between UltraVNC and TightVNC file transfer in the gui or by remote control you will probably be foiled by the “-rfbversion 3. For UltraVNC it works better, however if an UltraVNC client has initiated a file transfer dialog it will remain in effect until the dialog is closed. The UltraVNC and TightVNC settings can be toggled on and off inside the gui or by -R remote control.

Less safe, but to avoid figuring out where the correct XAUTHORITY file is, if the person sitting at the physical X session types “xhost +localhost” then one should be able to attach x11vnc to the session (from the same machine. Also, for some situations the “-users lurk=” option may soon be of use (please read the documentation on the -users option. ) The person could then type “xhost -localhost” after x11vnc has connected to go back to the default permissions.

He next should right-click on the icon and select “Properties” and go to the “Permissions” tab. In general for such cases, if it is feasible, it might be easier to ssh to his machine and set things up yourself. Sh and then instruct the user to right-click on the link and do “Save Link As” to his Desktop. Then in that dialog select the checkbox “Is executable”. Unfortunately in both cases the command output is lost and so errors cannot be debugged as easily. He should then be able to click on the icon to launch it. A similar thing appears to work in GNOME if under “Properties -> Permissions” they click on “Execute” checkbox for “Owner”. Then when they click on the icon, they will get a dialog where they can select “Run in Terminal”. One command-line free way, tested with KDE, is to name the file vnc. Another option is to right-click on the icon and select “Open With -> Other. It will appear as an icon, probably one that looks like a terminal or a command line prompt. ” and for the name of the application type in “/bin/sh”.

Home_mailbox: sets the path of the mailbox relative to the users home directory and also specifies the style of mailbox to be used. However, in this article we have chosen to use Maildir format (a trailing slash indicates Maildir format. To specify mbox format, the reader would use home_mailbox = Mailbox). Postfix supports both Maildir and mbox formats and readers are encouraged to read up on the merits of each for themselves.

The keycode skipping option was used to disable the ghost key: -skip_keycodes 93. From the x11vnc -xkb -dk -dk output it was noted that Mode_switch was attached to keycode 93 (no physical key generates this keycode) while ISO_Level3_Shift was attached to keycode 113.

One user reports this problem on HP-UX Rel_B. 047 3 numbersign numbersign numbersign and similar triple mappings (with two in the AltGr/Mode_switch group) of a keysum to a single keycode. The problem was traced to a strange keyboard mapping for the machine (e. 039 2 at at at. Xmodmap -pk output) that looked like:.
