kex --sl

Win-KeX Start Examples

kex - Desktop full screen
kex --win - Desktop Window
kex --sl - Desktop Seamless Mode
kex --sl -s - Desktop Seamless Mode with Sound
kex --sl --wtstart - KeX server and win-kex client in terminal
kex --esm - KeX desktop in native RDP windows

Prerequisite for Win-KeX

The Visual C++ Redistributable packages are required to run Win-KeX, if not already installed, the packages can be downloaded here. Install the Universal C Runtime x86 (vc_redist.x86.exe) and x64 (vc_redist.x64.exe). Kali Linux requires Windows 10 version 2004 or later, and the Windows subsystem for Linux – WSL 2.

To use Win-KeX, a computer with Intel virtualization function VT-x is required. The BIOS provides the operating system with the virtualization function, for which you activate the Intel (R) Virtualization Technology in the UEFI BIOS settings.

Linux Shell in Windows Terminal

Also now is a good time to mention the Windows Terminal, if not already installed, it is worth doing it now.

Troubleshooting

If VcXsrv is trying to start Win-KeX in Seamless Mode, an error is issued by VcXsrv:

A fatal error has occurred and VcXsrv will now exit.

In the log, it’s the last lines in /tmp/win kexsl_user.log:

winMultiWindowXMsgProc - Fatal error 1 on xcb connection
winClipboardIOErrorHandler!
winClipboardProc - setjmp returned for IO Error Handler.
(II) Server terminated successfully (0). Closing log file.

here you can try to start Win-KeX with sudo:

sudo kex --sl --wtstart -s

A solution also brought the deletion of the logs under /tmp.

sudo rm -f /tmp/*.log

And stop the KeX server with the –stop and –kill option.

sudo kex --stop
sudo kex --kill

After that, the start of kex as a normal user became possible.

kex --sl --wtstart -s

Also, a Win-KeX reinstallation can fix the error:

sudo kex --stop
sudo kex --kill
sudo apt-get purge kali-win-kex
sudo apt-get install kali-win-kex
sudo apt-get install dbus-x11

The Win-KeX help can also be useful.
