rdesktop in case remmina/rdp is not working

1. determine window id with xwininfo
2. rdesktop in the given window

$ xwininfo
...
xwininfo: Window id: 0x1a0000d "uxterm"


you need:
- username (loginname)
- domainname (like mycompany.com)
- window-id (returned by xwininfo, here: 0x1a0000d)
- rdp-domainname (like myvm.mycompany.com)

$ rdesktop -u  -d  -p - -K -a 16 -X  -f
