Bug Description

Affected system is Gnome Mint 12 64bit (added: and 32bit as well) on Thinkpad T520i with integrated Intel gen 2 graphics and 1920x1080 screen.

I installed a clean system from the live DVD (worked fine). On first boot Mint went all the way to the welcome screen, but since GRUB I only saw black screen, no display at all. Switching to console mode (ctrl+alt+f1-4) has no effect. If I remove the login password Mint logs in automatically. I can hear the sound, but display is still blank.

Booting in recovery mode gives me a fallback desktop with working display on vesa drivers:
$ inxi -G
Graphics: Card: Intel 2nd Generation Core Processor Family Integrated Graphics Controller
X.Org 1.10.4 drivers vesa,intel unloaded: fbdev Resolution 1280x1024@61.0hz
GLX Renderer Rasterizer GLX Version 2.1 Mesa 7.11

The problem persists after reinstalling Mint or trying to reconfigure Xorg.
I will be happy to work with you to provide more information.

So this is the Xorg.log from "normal" boot with no display. It's like X doesn't even know that there's anything wrong.

And this is Xorg log from the fallback mode.

Just to make sure I installed a 32bit version (with 3.0.0-13-generic-pae) of Mint as well and the problem is exactly the same. FullHD resolution when running off LiveDVD, completely blank screen on first boot after clean installation. It's not the backlight issue either, my backlight is turned on. Only the screen is 100 % #000000.

From the normal boot logs it really seems like X knows what its doing. No errors plus meaningful mode set.

Why then is there nothing on the screen?

I am taken aback by the overwhelming activity and attention this is getting.

This was my time well spent indeed. The Mint team don't even have the decency to close this bug without a fix. In the meanwhile I've moved on to a different distribution.
