           Summary: RandR12 fails on GF6600Go
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: anssi-4qZELD6Fgxhg9hUCZPvPmw@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


I have a laptop with GF6600Go, 10de:0148, 1400x1050 internal display, and DVI
and VGA connectors. Connected to the DVI connector is a 1680x1050 display.

When running X with RandR12 enabled, the laptop display shows distortions only,
while nothing appears on the external display.

Also, the server crashes after I run "xrandr --query".

I'll attach the X.org log and xrandr output.

Two things:

1 - lvds support is disabled atm
2 - A mmio-trace of the nvidia driver using the lvds + dvi configuration would
be helpful(actually, without it i have no clue what to do), since you have an
odd configuration.

A lot of bugs have been fixed in the meantime and your trace shows nothing out
of the ordinary. Could you try again? LVDS is still disabled though.

X server log when out of frequency, with xrandr run at the end

Tried again. The distortions on native display disappeared, but I still get no
picture: now I get a "out of frequency" error in the external display.

LVDS only, switch to another console, no restore, only distortions

I got it work, thanks to Maarten. I also enabled LVDS to test it, and it seems
to work, with some problems.
Attached log of console restore problem. Note that console restore works fine
when using DVI only.

Garbage on LVDS when switching DVI mode

Any switch of DVI mode causes LVDS to go garbage until it is switched as well.

Attached log of the following scenario:
Initial state: LVDS+DVI, 1400x1050,1280x1024
1. xrandr DVI to 1680x1050 => LVDS goes garbage
2. LVDS to 1024x768 => no more garbage
3. LVDS back to 1400x1050

The earlier xrandr "crashing" problem was my own fault, I had no other X
clients.

Garbage on LVDS stays even after X restart

The garbage mentioned in the previous comment stays even past X restarts.

Attached is the following reproducable scenario:
1. LVDS is garbaged by switching DVI mode with xrandr.
2. X is restarted (log starts here), garbage stays
3. Trying to switch LVDS to 1024x768, but X server drops connection to xrandr.
3. Trying again, now LVDS switched to 1024x768, and output works fine again.
4. LVDS switched back to 1400x1050, still works.

Notes:
- Garbage is the same kind that happens on failing console restore.
- When switching the LVDS mode, both displays go black for a moment. However,
when switching DVI mode, the LVDS does not go black, just goes to garbage
immediately

Ok, here's some tests that might help the LVDS restore issue, please try these
in order and reboot between each. You should not have anything connected on
DVI. Report back if any of them work :)

1) try current git and see if it's magically fixed itself
2) only call nv_set_tmds_registers in nv_driver.c when nv_output2->type ==
OUTPUT_LVDS (i.e. not for OUTPUT_TMDS)
3) Leaving change from 2) in place, force crosswired in nv_driver.c (a few
lines above nv_set_tmds_registers call) to 0
4) Leaving change from 2) in place, force crosswired to 1

1, 2, 4: Same as before, screen goes black and then fades to weirdness, no
console.
3: Screen fades to weirdness immediately, no blackness, no console


As the LVDS problems in LVDS+DVI mode (LVDS goes to weirdness on DVI mode
change) can be workarounded by setting the mode in LVDS again, could some
variation of that be tested here as well, i.e. restoring the mode twice or
something?

All the issues (console restore, DVI switch corrupting LVDS, LVDS not enabled
by default) are fixed on current git :)
