Software Tuning:

  2. I the VcXsrv shortcut properties, Target field append
     class=nowrap>-xkblayout us,ru -xkbvariant winkeys -xkboptions grp:caps_toggle
     line (to switch using Caps Lock or change last one to -xkboptions grp:toggle to switch using Right Alt).
  3. For *.xlaunch shortcuts, Additional parameters for VcXsrv field, append the same line as above.
• Xming X Server tuning:
  1. Install unicode and Cyrillic fonts from the Xming-fonts package from their site.
  2. I the Xming shortcut properties, Target field append
     class=nowrap>-xkblayout us,ru -xkbvariant winkeys -xkboptions grp:caps_toggle
     line (to switch using Caps Lock or change last one to -xkboptions grp:toggle to switch using Right Alt).

• StarNet X-Win32 tuning:
  1. In the Fonts section move all *_unicode fonts upper than their non-unicode versions.
  2. In the Command field of the connection add -lc option to xterm call.
  3. In the file

     C:\Documents and Settings\{User}\ Local Settings\Application Data\StarNet\X-Win32\XServer.config

     or

     C:\Users\{User}\AppData\Roaming\StarNet\X-Win32\XServer.config

     (for Windows 7) change existen Xkb line or add the following, if missing (as single line):
     
     
     <Xkb model="pc105" enableXKeyboardExtension="true" layout="us,ru" variant="winkeys" />
     
     It fixes two keyboards layout mode. NOTE: XConfig.exe may overwrite this line back to wrong one if you attempt to write its input tab options.
  4. Open

     C:\Program Files\StarNet\X-Win32 2012\xkb\symbols\pc

     include "group(ctrl_shift_toggle)"

     or

     include "group(alt_shift_toggle)"

     and then you may use Ctrl+Shift or Alt+Shift to change RUS/LAT (there is no keyboard switcher present by default and no XkbOptions or something like in the Xserver.config).
