Hi Matthias, 

do you mean like the following? Coz with the following set-up the l4linux is not booting and no error message came out: 

local mag_caps = {
mag = l:new_channel(),
svc = l:new_channel(),
};

hid = l:new_channel(); 

l:start({
          caps = {
   vbus = io_caps.con_bus,
   fb   = fb_caps.fb,
   mag  = mag_caps.mag:svr(),
   svc  = mag_caps.svc:svr(),
 },
 ev   = hid;
          log      = { "mag", "g" },
 l4re_dbg = L4.Dbg.Warn,
        },
"rom/mag");

local linux_caps = {
  log = L4.Env.log:m("rws");
  vbus = io_caps.linux_bus;
  rtc = rtc_caps.rtc;
  rom = L4.Env.rom;
  fb = mag_caps.svc:create(L4.Proto.Goos, "g=470x640,pos=10,20");
};


l:start(
        {
                caps = linux_caps,
ev = hid:srv(), 
        },
        "rom/vmlinuz.android mem=256M l4-input-srv.enable=1 console=ttyLvx ramdisk=rom/openwrt-x86-alix2-rootfs.tar.gz root=1:0 ramdisk_size=32768 l4x_rd=rom/openwrt-x86-alix2-rootfs.tar.gz init=/etc/preinit");

You need something like this in your lua script

hid = l:new_channel()

(for L4Linux)
ev = hid::svr()

(for mag)
ev = hid;

Don't forget to enable the input server with l4-input-srv.enable=1 on the
command line.

Matthias.
