Description Joël Tang 2012-03-25 14:09:50 UTC
Description of problem:

When I boot on a LiveCD of Fedora 16, the screen is black, and there is no input signal. The screen then goes to standby.

Version-Release number of selected component (if applicable):

Fedora 16.

How reproducible:

Just by booting a LiveCD.

Steps to Reproduce:
1. Boot on a LiveCD (a recent version).
2. Choose an item on the boot screen (e.g., for UnetBootin : Boot Fedora 16).
  
Actual results:

There is a black screen.

Expected results:

The screen should be recognized and functional.

Additional info:

My screen is : Asus VH222D. This bug is reproducible on all releases of Linux distributions (after April 2010 for Ubuntu).

This bug persists with Fedora 17, and doesn't exist when I boot with Vesa (low graphics).

Comment 2 Bill Nottingham 2012-03-26 15:20:15 UTC
What sort of graphics hardware?

Comment 3 Joël Tang 2012-03-26 19:17:06 UTC
I'm using an APU (AMD APU A6-3650). I think the LiveCD wants to search a specific driver for this graphics hardware, but there is none.

P.S. : After the installation, Fedora seems to use the basic graphics mode, without manipulation.

Please attach dmesg, also after updating f16 you should have a newer kernel that support your GPU.

Support ? This bug appears when I boot on a LiveCD. After the installation, it works. Do you mean that I will be able to use normal graphics?
