[Nouveau] Nouveau doesn't use the maximal resolution of my screen and GPU

Yes. I attached the logs.

(There is several error messages.)

[Nouveau] Nouveau doesn't use the maximal resolution of my screen and GPU

There is no sign of the nouveau kernel module being loaded. Make sure
it's loaded, otherwise it won't work. Some distributions blacklist it
in modprobe.conf or a related file. I believe the nvidia blob
installer might as well.

Actually, looks like you've explicitly disabled it --

Oct 28 21:57:22 victorlefevre-MS-7235 kernel: [    0.000000] Kernel
command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-38-generic
root=UUID=7b0559d9-fbbe-4635-b244-bda94aa0a640 ro quiet splash
nomodeset vt.handoff=7

"nomodeset" turns off all modesetting, which disables nouveau from
being loaded. Remove that, and you'll get further.

[Nouveau] Nouveau doesn't use the maximal resolution of my screen and GPU

You're right, fbdev managed the graphic interface...

I correct the boot options, Now, Nouveau works !

Cf the new Xorg.log

xrandr give this output :

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
DVI-I-1 connected 1440x900+0+0 (normal left inverted right x axis y 
axis) 408mm x 255mm
    1440x900       59.9*+   75.0
    1280x1024      75.0     60.0
    1280x960       60.0
    1280x800       74.9     59.8
    1152x864       75.0
    1024x768       75.1     70.1     60.0
    832x624        74.6
    800x600        72.2     75.0     60.3     56.2
    640x480        75.0     72.8     66.7     60.0
    720x400        70.1

Thank you a lot.

I have only a little problem now. In all applications, the displayed 
color for the text is not correct. It's green khaki instead of black. 
(cf the screenshoot)

Can it come from Nouveau?
