Ubuntu-desktop stuck: displayport blinking got display panic
Raw
fix.md

After reboot, gnome got stuck right after the purple "ubuntu" with several dots below, then only one non-flicking cursor on the top left. Then into recovery mode, try startx it says

X: cannot stat /etc/X11/X (No such file or directory), aborting

Fix

sudo dpkg-reconfigure xserver-xorg-lts-utopic

This restores the symlink /etc/X11/X -> /usr/bin/Xorg. I've tried to modify lightdm to gdm doesn't work. And xorg dpkg reconfigure doesn't work because I don't have it installed. I found I have xserver-xorg-lts-utopic.

  • Had another experience: sudo dpkg-reconfigure xserver-xorg for cassandra/eucalyptus VMs that only support older kernel

Post-fix

Dash doesn't work, no app can be found. So a quick run

rm ~/.cache/software-center -R
unity --reset &

If ended up with ERROR: the reset option is now deprecated, unity --replace & is the non-deprecated version
