           Summary: c51 lvds script failure in randr12 mode. if I start the
                    X server the screen is black and the framebuffer too
                    because it trys to link the whole output to the monitor
           Product: xorg
           Version: 7.3
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: maxmusterm-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


I use a md98300 medion notebook with a nVidia Geforce Go 6150 graphic
processor.
You have to change the BIOSLOG to work.
I will later add a few Xorg logs for debugging.

Issue can be worked around by worked around by turning call_lvds_script into a
noop.

It is possibly suspicious that in doing dpms on at the end of the modeset,
0xD3BF: [ (0x56) - INIT_CONDITION_TIME ] does not successfully complete: "
0xD3BF: Condition still not met, skiping following opcodes". A comparison xorg
log from darktama's C51 executing (almost) the same script does successfully
complete.

Thomas: after nouveau has failed to start X, does the VT return, or does the
screen remain blank until the laptop is rebooted?

Two other things to try:
1) does it work if the timeout is increased: in nv_bios.c, function
init_condition_time(), change "BIOS_USLEEP(2000);" to "BIOS_USLEEP(20000);"
2) if 1) does not work, does it work if the off script is not run: again in
nv_bios.c, function run_lvds_table(), just below "case LVDS_PANEL_OFF:" add
"return;" on a new line.

The Screen remains blank and black.
Yes even after closing X.And yes the framebuffer is black too.

I don't have to test the second way cause the first one works fine.
Thank you Stuart

Fix based on 1) from comment 2 now pushed. Please test with a fresh git
checkout, and close this bug if it is solved.
