I was able to figure out the cause of this problem I was having Unable to boot Ubuntu 14.04. The X server is refusing a connection. I was able to boot by pressing shift continuously and I was able to boot but it does not open the graphics display of Ubuntu trusty.
sudo service lightdm restart and
start. They both don't seem to work. In effect I have access to a tty terminal where I can issue commands and see my data but the X windows access is broken.
Thanks to Serg I installed
gdm , but that also failed to display.
Then we tried
sudo startx $(which unity)
We got this error
/usr/bin/X : error while loading shared libraries : libimf.so cannot open shared object file: No such file or directory
When I looked up the type of display that I have
VGA Compatible controller product : 4th generation core processor family integrated graphics controller vendor : Intel Corporation
As given by
sudo lshw -c display
So it is missing a shared library from Intel. Can somebody recommend how to fix this problem ?
