Nouveau - Oct 2007 - [Bug 12833] New: Geforce 8400M GS (id 0x427): stick to 800x600

http://bugs.freedesktop.org/show_bug.cgi?id=12833

           Summary: Geforce 8400M GS (id 0x427): stick to 800x600
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: debian at oursours.net
         QAContact: xorg-team at lists.x.org


I switched from the nvidia-glx-new driver to the Ubuntu 7.10 packages from
"raof". It was git snapshot b36fbf174849b04928efda2909c461b6c1688cdc.

X boots fine and GDM appears, but the screen is set to 800x600, while the
native resolution is 1280x800. The computer is a Dell xPS M1330. The card
vendor is said to be "Dell". I don't know how much Dell is
modifying the
design.

What do you need to introspect and maybe fix it? I hoped to find such
instructions on the wiki. I didn't have the time to save the X log. I'll
post
it later.

I know git and compiling myself so I can try patches and branches. I already
submitted the renouveau dumps.

I am looking forward to helping support my card model with XRandR 1.2. I
haven't tried glxgears but 3D is not a priority to me.

My mistake, X didn't start at all, and Ubuntu started in fail-safe (VESA)
mode.
I don't think you're interested in VESA bugs.

The kernel module failed to insert because of unresolved symbols. I will drop
the Ubuntu packages and compile it myself for a more accurate bug report.

After git clones of drm and nouveau, compiling and installing, I restarted. I
had to manually load the new drm module instead of the default one and... it
worked!

The native resolution of 1280x800 was enabled by default.

My first impression is how the refreshing is slow.

Some output from xrandr:

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA1 disconnected
DVI1 disconnected
LVDS connected 1280x800+0+0 0mm x 0mm
   1280x800        0.0*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
   640x400       120.0  
   640x384       120.2  
   512x384       120.0  

I connected a screen on VGA1 but nothing changed. But I expected it to be named
VGA.

I attach the Xorg log.

What do you need now to help improve support?

NV50 support is far from perfect, i'm trying to get switching back to a VT
to
work. The slowness is to be expected and likely involves text rendering.
Come to our irc channel (#nouveau on freenode) if your interested in helping
out.

------- Comment #8 from debian at oursours.net  2007-10-29 13:42 PST -------
I tried your nv50.patch.

Without it, I switch to the first virtual console and get a black screeN. I
switch back to X and get back my desktop. Nothing crashed.

With your patch, this is exactly the same behaviour.

I tend to think I missed a step, so here is my bash history:

cd xf86-video-nouveau/
git-apply nv50.patch
make
sudo make install

I saw nv50_display.c compiling, so the driver must be updated.

I updated drm & nouveau, and now the screen is black. I can still use the
keyboard though.

I attached the X log.

Git head 5ca10da0c7dd2fd689cc4369e37ed385a0c10d21 fixed the black screen, which
retrospectively was probably the screen switching off to prevent any damage.

AIGLX is deactivated in my xorg.conf at the moment.

But I still have the default frequency at 0 Hz. See xrandr output:

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA1 disconnected
DVI1 disconnected
LVDS connected 1280x800+0+0 0mm x 0mm
   1280x800        0.0*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
   640x400       120.0  
   640x384       120.2  
   512x384       120.0  

I'm eager to test hotplug.

I'm very confused, i see one or two debug statements from the pre-G80 driver
in
your log, also why that commit fixed your situation is unknown, it's
impossible, or it should be.

I can't tell you the magic behind, but I still can try git-bisect between
7054de29c589a7be0a6b027f3067ae2c02e2fc45 and HEAD.

This is a Dell manufactured adapter. I hope this is not some rework of a G70
design!

I've fixed the small leak of pre-G80 code into G80, but this did not touch
the
commit you mentioned.

Should this be closed? (ignoring the wider scope/lacking good g80 support)
