I have selected xorg-server, xinit, vim and gdb packages. I have modified the Xwin server configuration as described in https://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-startxwinrc-exit and later I have successfully started it by using the action "cygwin-x\xwin server" under Windows programs menu.
