Cygwin X applications do not launch

Cygwin X applications do not launch

[Jones, Michael]

I have a fresh install of Cygwin, with Cygwin X.
The problem I have is that X applications do not seem to run.

If I try to run gedit or emacs, for example, the applications seem to just return 0 immediately:
----------------------------
me@mycomputer ~
$ gedit &
[1] 10244

me@mycomputer ~
$ emacs &
[2] 10976
[1]   Done                    gedit
----------------------------

Similarly, if I try to start either of these applications from the X Applications Menu on the taskbar, they don't launch.
The Cygwin log file shows the following, indicating that the application started, and then exited straight away:

----------------------------
(xwin-xdg-menu:13896): GVFS-WARNING **: Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.Daemon: Timeout was reached (g-io-error-quark, 24)

executing 'xterm -title '/home/me/.xsession-errors' -e less +F /home/me/.xsession-errors', pid 8080
(pid 8080 stderr) xterm: cannot load font "-Misc-Fixed-bold-R-*-*-13-120-75-75-C-120-ISO10646-1"
executing 'gapplication launch org.gnome.gedit', pid 9288
pid 9288 exited with status 0
----------------------------

Any ideas? It's driving me nuts! I've tried a fresh install of Cygwin, with the same results.

Many thanks,
Mike

and see if a there is any pop up error ?

I assume you run it from xterm and not mintty, correct ?

Can you send me the gedit.strace by private mail ?

Hi Mike,

I think the AV is interfering.
A lot of Windows DLL's are loaded at very low addresses:

--- Process 10964 created
--- Process 10964 loaded C:\Windows\System32\ntdll.dll at 0000000077860000
--- Process 10964 loaded C:\Windows\System32\kernel32.dll at
0000000077740000
--- Process 10964 loaded C:\Windows\System32\KernelBase.dll at
000007fefd7e0000
--- Process 10964 loaded
C:\Windows\System32\tmumh\20019\AddOn\6.80.0.1007\TmUmEvt64.dll at
000007fefc290
000
--- Process 10964 loaded C:\Windows\System32\psapi.dll at 0000000077a00000
[cut...]

0000000075070000
--- Process 10964 loaded C:\cygwin64\bin\cygwin1.dll at 0000000180040000


for ntdll.dll for example:
0000000077860000 your system
00007ffd81700000 my system

and the exception at the end of strace is in that area
00000000779332ca

   160  398012 [main] gedit 10964 sigprocmask: 0 = sigprocmask (0, 0x0,
0x6000A2AA0)
--- Process 10964 thread 8560 created
--- Process 10964, exception 80000001 at 00000000779332ca
--- Process 10964 thread 12024 exited with status 0x80000001

can you try without with AV or excluding the "C:\cygwin64" directory ?

Regards
Marco

Hi Marco,

You are correct!
With AV disabled, everything seems to work fine.

I now need to work with our IT guys to figure out how to configure the AV so that it does not interfere.

Many thanks for your help diagnosing the cause of this problem!

Regards,
Mike
