ubuntu stay in login & install arch

sth wrong in my ubuntu 14.04.02 LTS

_gnome mistake_stay in login

 -> I key my password but stay  [ user_name ] [ log in ]

1\ I can login  in guess-session.quick finish my os lab report

   program and run shell in tty1/2/.. and  run VirtualBox in graph terminal , if guess unavailable to w/r  files somtime , try to munt a a usb device .. - _-|| 

2\cmd : ~@host >> ls -la 

    check file [.Xauthoriy ] , owner is 'user' or root (it should be user)

     if is root : type " chown user_name:user_name .Xauthority" , "ls -la" check it

3\it still not work!

  check ~/.session-errors

  see the last line : [disconnected from motified D-dbus ( seems relate to IPC -_- ) ]

   I was angry at that moment and remove dbus ...

  THE MOST TERRIBLE THING !! guess seesion can't do anything now !

   I can only stay in tty1/2.... T-T

---------------------------------------------------------------

  that maybe the end ... I decide to give up .Ubu , try SUSE or Arch , I find a arch.iso in my computer and prepare a bootable usb

  loader os ...

  seems wifi device don't work or active ...

  to do homework I quickly install ubuntu but I still don't like it ...  

----------------------------------------------------------

  try agin!

I want to access to campus network but it need client software..

download yah3c in ubuntu, mount my sda(linux) and get it

[access file on ubuntu] if you can write on your USB device skip it

>> fdisk -l  (suppose my ubuntu in /dev/sda1)
>> mkdir /mnt/da1
>> sudo mount /dev/sda1 /mnt/da1
 

 

not python !!

come back ubuntu to download source

when compiling python in arch -> no make ?

anyway , compile needed tools in arch and I think we can be access to wired network

...

continue
