Bug Description

Steps to reproduce:

1. Wait until lightdm shows up (In my case, set up to open xbmc session)
2. Switch to any VT: ctrl+alt+f1
3. Switch back to X11: ctrl+alt+f7 (or whatever VT you have xorg on)

Screen stays on, but everything is black.
To get it Xorg again, you have to switch to another VT, stop lightdm and start it again.

As Ricardo Salveti told me when he confirmed the bug on IRC, screen sometimes is White instead of Black when you try to switch back to Xorg. In my experience, I've experienced black screen when I'm in XBMC, and white when i'm using Unity.

Moving to 12.04 as it's still an issue, and no progress was done during this cycle. Once we get the latest kernel it'd be also nice to try to reproduce there, as there are tons of changes in the pipe.

This is still happening with the newer driver and kernel for the 12.04 release. Moving to 12.05.

Still happening with 12.06, to be tested with SGX DDK 1.9 that will be available during 12.07.

The issue is different with SGX DDK 1.9, as it's now restarting X11 as soon as you go to a virtual console. Moving to 12.08 for further debugging.

Can confirm the bug, same here... latest precise with latest kernel and pvr drivers.
