New Build of 14.04 doesn't arrive at Login Screen

[jamesisin]

Just built a Lenovo T410s with 64 bit Ubuntu 14.04.1, added some basic stuff (ssh, smb, Opera, Spotify, Clementine), and ran updates. Upon rebooting it doesn't get past the screen which merely says Ubuntu (and has the five colored dots). I do hear the Login Screen drum roll and I can ssh into the machine (sure glad I added that before the reboot).

Any help is appreciated.


Thanks,

James

Anybody?

What are the hardware specs of your machine? specially the video adapter. And what drivers are you using?

[jamesisin]

I have not enabled any third-party drivers, so whatever is chosen by the OS for a T410s of that ilk. If you'd like me to run specific commands I am able to ssh into the box.

[mc4man]

shows as • Intel® HD Graphics and NVIDIA® NVS3100M Graphics
the intel may be 3000?
You could try booting to recovery > resume.. which will attempt to boot normally without any video driver loaded
If that works then search out issues with Intel HD Graphics 3000 (Sandy Bridge) & 14.04.1

[jamesisin]

That was helpful but we are not done yet.

Going Recovery --> Resume did give me a login screen. I then logged in and the accoutrements of the login screen left leaving the background. The desktop never arrived. The mouse is active but won't interact with the background image (why would it?), and I could probably change to a different tty to get a prompt (but didn't try).

Through an ssh connection I looked at GPU information:

The blank screen with active mouse is sign of Unity plug-in not running. This is display driver config situation.
Can you try to get to tty and hit "startx" and see if that launches unity for you?
if that doesn't work, get to tty and rename ~/.Xauthority folder to something else. and re-boot the machine. re-booting will re-create that folder.

[mc4man]

If continuing to get stuck -
Your intel driver apparently isn't loading *-display UNCLAIMED

Assuming the install worked until you updated attached is full list of 14.04.1 updates on a default install.
Some of the updates may be suspect to your issue, ie. the kernel, xserver-xorg*, ect.
(though the xserver-xorg-video-intel update doesn't mention sandybridge

Have you tried booting to another kernel? (if you did update the kernel, installed is 3.13.0.32.38, update is to 3.13.0.37.44

[jamesisin]

sp40140 - The screen after login is not blank; the desktop image is present. If I switch my tty to f2 and startx I get a black screen with no mouse. (I am still able to switch between all the tty's.)

mc4man - I believe you are correct in that I only have two kernels on that machine (32 and 37). Let me try the first and see where that takes me.

[jamesisin]

Looks to be about the same behavior. The startx does have a little output before it stops so that may be useful.

Kernel 32 after initializing a bunch of built-in extensions:

Loading extension GLX
Loading extension NV-GLX
Loading extension NV-CONTROL

Kernel 37 after initializing a bunch of built-in extensions:

Loading extension GLX

(While attempting to use the Recovery --> Resume under 32 I saw a bunch of "failed to disable graphis turbo" messages in case that is interesting.)
