Description David Keller 2009-07-16 07:41:14 UTC

Hi.

Using 6.12.1 xf86-video-ati on a 1.5.3 xorg-server.

When Xorg starts, the screen becomes dark. Moreover it is still dark after a VT switch, although the system is alive (ssh works).

Trying to switch the backlight using keyboard is'nt working.

Then i connected another screen on the VGA-0 output, without sucess: the two screens remain black (even with Enable set to true in corresponding Monitor sections).

Corrected target version 7.1 -> 7.2.

Comment 6 Alex Deucher 2009-07-16 08:32:55 UTC

this is probably a dupe of bug 22755.  Do the patches there help?

Comment 7 David Keller 2009-07-16 08:55:35 UTC

No, same behaviour: the screens goes black and force me to reboot.

By the way, the kernel is the 2.6.29.

Comment 8 Alex Deucher 2009-07-16 08:58:40 UTC

Did this used to work with an older version of the driver?  If so which one?

Comment 9 David Keller 2009-07-16 09:07:43 UTC

I was running on fglrx so far.

Anyway, one year ago, when giving a shot to the xorg driver, I experimented the same error.

In the Xorg.log, I can see the LVDS is disabled ("Output LCD1 disable success") after calling  RADEONScreenInit, and is never enabled again.

Xorg.log with verbose mode

Running with video-ati from git trunk + verbose enabled, I noticed that RadeonScreenInit doesn't seems to complete.

radeon.c:3544 

xf86DrvMsgVerb(pScrn->scrnIndex, X_INFO, RADEON_LOGLEVEL_DEBUG,
                    "Initializing fb layer\n");

is never printed in the Xorg.0.log.

Comment 11 Michel Dänzer 2009-07-16 10:12:16 UTC

All log files have

(II) RADEON(0): DRIScreenInit for fglrx driver

so some X server components are still left from fglrx. You'll have to get rid of those to be able to use other drivers.

Comment 12 David Keller 2009-07-16 10:24:23 UTC

Ouch !

Do you have an idea of the identity of theses components ? I am lost.

I use Xorg OpenGl.
fglrx kernel module isn't loaded.

Currently, I am recompiling xorg-server with only ati & vesa video card drivers to be sure.

Comment 13 David Keller 2009-07-16 10:40:43 UTC

You rock ! Recompiling did the trick (shame on me).

Thank you very much Alex & Michel :)
