[-- Attachment #1.1: Type: text/plain, Size: 9833 bytes --]

Dear Linux folks,


as reported in the channel #radeon on <irc.freenode.net>, with the
laptop Asus U38N-C4010H with an AMD Radeon HD 7600G
(Trinity A8-4555M) I am unable to get something displayed on the screen
with modesetting enabled. The backlight of the screen is on, but nothing
is shown on the screen. Booting with `radeon.modeset=0` on the Linux
kernel command line works. I was able to reproduce this problem with
Grml with Linux 3.10 and 3.11 and Debian Sid/unstable with Linux 3.12.6.

Attaching a VGA monitor to the mini VGA connector using an adapter,
nothing was shown on the monitor either.

The following is the output I get when starting with `radeon.modeset=0`
and then doing `sudo modprobe -r radeon` and `sudo modprobe radeon
modeset=1`.

The screen turns off shortly (backlight too) and then only the backlight
comes back up.

Any help is appreciated.


Thanks,

Please file a bug: https://bugs.freedesktop.org (Product: DRI,
Component: DRM/Radeon) and attach your xorg log and dmesg output.
