After selecting an entry from the Grub menu and booting starts, the screen goes blank, and the monitor displays "no signal". When booting ends and X starts up, the screen comes back to life, and the LightDM login screen appears.
I'm using a Radeon HD 6850 with the opensource driver.
Kernel version: 3.5.0-15.23-generic 3.5.4
This is a regression, as the issue wasn't present with an earlier 3.5 kernel (.15). When I updated recently, I updated to kernel version .22, which exposed the issue. Updating to a newer version (.23) did nothing to fix the issue.

After selecting an entry from the Grub menu and booting starts, the screen goes blank, and the monitor displays "no signal". When booting ends and X starts up, the screen comes back to life, and the LightDM login screen appears.
I'm using a Radeon HD 6850 with the opensource driver.
Kernel version: 3.5.0-15.23-generic 3.5.4
This is a regression, as the issue wasn't present with an earlier 3.5 kernel (.15). When I updated recently, I updated to kernel version .22, which exposed the issue. Updating to a newer version (.23) did nothing to fix the issue.
Update: Installing the kernels did not fix the issue either:
3.5.0-16.24, 3.5.0-16.25

Update: Apparently the Ubuntu kernels can't handle the "vt.handoff=7" option properly, which causes the black screen.
See my comment below for how to fix it:
