My problem started after i rebooted my pc from the terminal , not doing any upgrades ,just a simple reboot , i saw some warning about low space on the home folder nothing else but i think it is unlikely that this is the problem . My computer booted just fine ,but when i type my login password it freezes and nothing happens . I can't acces tty shell with CTRL+ALT+F(1...6) ,when i do this sometimes it loads all that output and keeps bring me the login screen and freezes , i managed to get to a login in tty once put after i type my password it reloading the login screen . I have installed on this machine a fluxbox windows manager and i could login there , and list my files and did some commands i saw on related problem posts , don't know if it's stupid or not .. tried reinstall ubuntu-desktop , unity what . nothing works for me ..

Could be that being out of space is causing all the problems... that's the first error you mention, so should be the first thing fixed.
or a filesystem (FS) problem...
or there's some error in the GUI desktop...

But running from a live USB/DVD is the first step, to:

  • Check the FS for errors - [Note: if your hard drive is failing, then it will probably get worse no matter what, a whole-partition backup with gddrescue may be required, then fix & backup from the copy]

    To do a read-only check (if you're really paranoid about losses, but you should already have several backups in that case). 

    fsck -nv /dev/<device>

    But you're probably using an ext3/4 filesystem on / & /home, so fsck would use the e2fsck program, and these options would be useful:

    • -n Open the filesystem read-only, and assume an answer of 'no' to all questions.
    • -f Force checking even if the file system seems clean.
    • -p Automatically repair ("preen") the file system. This option will cause e2fsck to automatically fix any filesystem problems that can be safely fixed without human intervention.
    • -v Verbose mode.

  • Mount the partitions - as read-only (mount -o ro <partition> <mountpoint>) if you're concerned about them getting changed.

  • Back up your files - Copy wanted files to some other partition, delete unwanted ones, to solve the out of space problem and prevent catastrophic loss in case there is a problem in the future.
  • Remove/re-install packages from a chroot environment (but if you can boot into single-user mode with networking that might be easier.
  • Even re-install if you think the errors are too serious to overcome.
