Hi,
I just spent a day trying to work around my newly upgraded Ubuntu 14.04 booting into a black screen without success and becoming desparated.
What I did: Upgrade to 14.04 LTS from 13.10 via command line. Everything procceeded without problems.
The status now: GRUB shows. After I select any Ubuntu starting option I still have on my system, the Ubuntu start screen with the dots appears, changes into a black screen with a white cursor in the upper front corner. At this stage nothing will get me out of this besides a manual restart (Alt + F1 or F2 does not work, no keyboard reactions otherwise). This effect also happens with the Ubuntu 13.10 kernel stilled imaged on the system. Graphics failsafe modes won't boot at all.
My system:
http://paste.ubuntu.com/7596717/
Thinkpad X1, dualboot with Windows 7. Intel HD 4000 graphics card.
There is no file /etc/X11/xorg/conf.
lspci -nnk | grep -iA3 vga gives:
00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)
Subsystem: Lenovo Device [17aa:21f9]
Kernel driver in use: i915
00:14.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller [8086:1e31] (rev 04)
/usr/lib/nux/unity_support_test -p gives:
No protocol specified
Error: unable to open display
What I tried:
Many suggested solutions from other forum threads, including
Resetting unity, dpkg --reconfigure, several uninstallation and reinstallation of fglrx / nouveau / nvidia graphics drivers
Booting 14.04 from a life USB, which works great and enables me to write this post, but I don't manage to fix my local 14.04 installation :(
Any ideas?
Thanks a lot,
Alice
