           Summary: Getting inverted colors after having launched Virtualbox
                    with Nouveau driver
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: thomas.pegeot-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org

Hello,

Lauching Virtualbox on my computer makes the screen get inverted/negative
colors when i open new qt/kde applications. If i focus on an older windows
(launched before Virtualbox), the screen goes back to normal colors, and vice
versa. When the colors are inverted, my screen looks like this :
http://bbs.archlinux.org/viewtopic.php?id=77040 (it's not my thread). 
Restarting X solves the problem. ;)

The kernel (master branch), mesa, libdrm, xf86-video-nouveau were compiled this
morming from the git repos. ;)

I got this problem for the first time about 1 month ago but I didn't really
know whether this problem was related to nouveau or not...

I use KDE with compositing (via Xrender) and toggling off compositing doesn't
solve the problem. 

This morning i tried the NV driver, and this problem didn't occur. 

My graphic card : 05:00.0 VGA compatible controller: nVidia Corporation NV41.1
[GeForce 6800] (rev a2)

Feel free to ask if you have any further questions. 

Regards

Thank you in advance!

At the very least give some kernel and xorg logs.

Here are the different logs you ask for. ;)

After having launched Virtualbox, the following lines are added to the kern.log
: 
gentoo thomas # diff kern.log /var/log/kern.log
8936a8937,8940
> Sep 18 13:57:16 gentoo kernel: [  349.772788] warning: `VirtualBox' uses 32-bit capabilities (legacy support in use)

Thank you in advance! ;)

Disabling opengl in Virtualbox solved the problem. ;) I even didn't know that
it was enabled ... :(

Were you using the Nouveau Gallium/DRI driver or swrast?

The description sounds like VirtualBox sets up a window palette, a feature from
the dark ages. X desktop was 256-color so it used a palette. If an application
set up its own palette, all other windows would draw with "bad" colors while
the application had focus. IIRC.
Is you X in 256-color paletted mode? I don't know if we even support that, so
all this is unlikely.

Actually, I've been using the Mesa ebuild from the X11 overlay for a while with
gallium support enabled, as well as Nouveau (VIDEO_CARDS="nouveau)". 
What is swrast? 

> Is you X in 256-color paletted mode? I don't know if we even support that, so

According to xdpyinfo, the default number of colormap cells is 256. Is that
what you want to know ? If i'm wrong, just tell me where i can find this and
i'll tell you. ;)

Okay, that is enough to make this report invalid. We do not take Gallium3D bugs
yet.

> What is swrast? 

The Mesa software rasterizer, the only supported OpenGL renderer for Nouveau at
this time. glxinfo would say:
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer

"Depth of root window". I bet you would know if you were in 256-color mode.
Ever looked at 256-color gifs? Not to mention that anything OpenGL would
probably refuse to work.

I think I had the same problem even when gallium was disabled ... but i'm not
sure about it. If i've time, i'll try it again. ;)
Anyway, i don't need OpenGL support in Virtualbox, disabling it is fine for me.
Even disabling Gallium is ok.

Because of my English, i definitely missed the point about the 256-color mode. 
You're right, i would have known if i were using this crappy mode. :p

depth of root window:    24 planes
