Dear Marco (and R0b0t1),

Following your suggestions, I have tried to re-install X11 in the Windows Safe Mode to exclude the influence of AV. The X icons still didn't show up. So I am not sure the problem was caused by AV.

On the other hand, I tried to run the \etc\postinstall\xinit.sh.done and \etc\postinstall\xlaunch.sh.done commands in the Cygwin terminal. Now both the Xwin Server and XLaunch icons showed up under the Cygwin-X direction in the Start Menu. Thanks for the guidance in the previous email!

However, when trying to run XLaunch, I got the problem of "A fatal error has occurred and Cygwin/X will now exit. Can't read lock file /tmp/.X0-lock".  I have tried the following to resolve the problem (as instructed in FAQ Q. 2.3 and Q. 4.2):


1)      In the start menu shortcut,  amended the target of Xwin Server to add an "-- -nolock" option, which didn't work;

2)      In the Cygwin terminal, ran "startxwin -- -nolock", but got the error

" cat: /tmp/.X0-lock: No such file or directory
                 xauth:  error in locking authority file /home/xp902121/.serverauth.5048
                 xauth:  timeout in locking authority file /home/xp902121/.Xauthority"

So far, I still couldn't solve the problem. If you have any suggestions, that will be very appreciated. If needed, I may send separate email to the mailing list.

Many thanks,

Zuowei

Dear Marco,

Thank you very much for the suggestions.

Concerning your questions:

1. What system and AV do you have ?

System type: 64-bit Operating System, x64-based processor (Intel(r) Core(tm) i7-6700CPU @3.40GHz)
Operating system: Windows 10 Enterprise
AV: Sophos Anti-Virus; Windows firewall

2. Can you follow https://cygwin.com/problems.html and provide as attachment the cygcheck.out ?

The cygcheck.out file is 891KB in size, so when being attached as a plain-text attachment, the email was rejected. Would it be possible to send this output file to a different email address or in two separate files?

There is no "/var/log/xwin/XWin.0.log" file in the related directory.

3. What is the output of rebase -si | grep cygiconv-2.dll

$ rebase -si | grep cygiconv-2.dll
/usr/bin/cygiconv-2.dll
            base 0x0003e3ca0000 size 0x00105000

4. and of grep System32 /proc/self/maps | head -n 5

$ grep System32 /proc/self/maps | head -n 5

Sorry to both again. Below is what I got when running the command in the Cygwin terminal :

Dear Marco,

Thank you very much for the suggestion!

I have run the command line as you suggested and got the output of xinit-1.3.4-14, but nothing else happened. Is there anything else I need to do, say reboot the PC?

Many thanks,

Zuowei

the Cygwin-X entries in the Menu are created by the
script:

/etc/postinstall/xinit.sh{.done}

It belongs to the package
$ cygcheck -f /etc/postinstall/xinit.sh
xinit-1.3.4-14

You can run it again by the cygwin terminal.

Subject: Problem with installing Cygwin/X on Windows 10 PC: no icon created

Dear All,

I have been trying multiple times to install Cygwin/X on my Windows 10 PC using setup-x86_64.exe and as an administrator. Even though the installation was shown to be successful, there was NO Cygwin-X icons such as XLaunch/Xwin Server icons created either on Desktop or Start menu. I have followed the installation instructions precisely and read through many posts about installation of Cygwin/X, but couldn't find any solutions.

To give some more background: I have been installing Cygwin and Cygwin/X many times on different windows PCs and never had such a problem before. On this Windows 10 PC, the Cgywin64 Terminal was installed successfully and is running properly. But Cygwin/X does seem to be installed properly.

Any suggestions will be high appreciated.

Best regards,
