x goes blank and tty1,2,3,4,5,6 give login

Greetings,
Problems with 12.04.2 LTS. I've reinstalled 3 time on different dell hardware (laptops). When system screen locks I can't get back to x, ssh sessions won't work either. I can get to tty and have a login screen, but each time I try to put a user in I don't get an opportunity to put a password in, just goes back to login? It seems the only way I can get out of this state is to power down the system which reboots into a kernal panic and all is dead and requires a reboot.

Any suggestions on how I can safety reboot of get something out of one of the tty?

thx,,

Is this a server install? Are you trying to use startx?

X has frozen so I go out to other ttys and get a login. However, whenever I put something in the login nothing gets accepted. E.g. sudo reboot just comes back to the login....it's like some kind of loop?

A reboot will take you back to tty if this is a server install, thats why I asked. If this is a desktop install maybe try reinstalling your display manager, see if that helps or see if you have any broken packages.

Display manager

Code:

---

sudo apt-get install --reinstall lightdm

---

Fix broken packages

Code:

---

sudo apt-get -f install

Could be your .Xauthority is owned by root- run

Code:

---

ls -al | grep .X

---

while in your home directory. Check the permissions- you should have it should be rwx all around. If not you should change ownership of it-

Code:

---

chown username:username .Xauthority

---

Can't run any commands from tty, I seemed to be doomed to recycle power which give kernel panic and then I'm not sure what I can do from grub?

Do you have any older kernels in grub? Try one.

older kernels exist but, from multiple installs related to this problem. Any command option from GRUB which may help me fix issues?

thx for the help
