Red Hat Bugzilla – Bug 806629
VGA, no input signal (during the boot)
Last modified: 2012-04-02 16:26:53 EDT
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):
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).
There is a black screen.
The screen should be recognized and functional.
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).
What sort of graphics hardware?
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?
