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

[pipesbi]

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,,

sudo reboot

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

sudo reboot

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?

thx,

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

sudo apt-get install --reinstall lightdm

Fix broken packages

sudo apt-get -f install

Could be your .Xauthority is owned by root- run

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-

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.

[pipesbi]

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
