There might be better ways to do this, but for me the following procedure worked:

1. Connect a VGA monitor together with a DVI monitor, delete /etc/X11/xorg.conf, reboot
2. Install nVidia driver version 173.14.28, which is not the current driver but the previous one (did not succeed when installing the current driver)
3. Start Applications/System/NVIDIA Server Settings, then open X Server Display Configuration
4. Set the digital monitor to absolute position, VGA monitor to relative, display mode to TwinView
5. Copy content of X Configuration File to /etc/X11/xorg.conf
6. Reboot and disconnet VGA monitor
7. if KDE shows any display issues, delete folder ~/.kde and reboot again

Install glxinfo to check whether nvidia's glx module was loaded:

apt-get install mesa-utils

After installing the proprietary nVidia drivers, the splash screen is broken. To get it back, do the following (as root):

apt-get install v86d hwinfo

Find the supported resolutions by using hwinfo, e.g. output of highest resolution: Mode 0x03f0: 1280×1024 (+5504), 24 bits

hwinfo --framebuffer

Edit /etc/default/grub to make sure we boot with uvesafb framebuffer. For the mode_option parameter change to your native screen resolution you see from running the above comment:

...
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1366x768-24,mtrr=3,scroll=ywrap"
...
GRUB_GFXMODE=1366x768

Edit /etc/initramfs-tools/modules to include uvesafb by adding the following line:

uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap

Force the use of framebuffer:

echo FRAMEBUFFER=y | tee /etc/initramfs-tools/conf.d/splash

Update grub and initramfs, then reboot:

sudo update-grub2
sudo update-initramfs -u

setxkbmap us
sudo dpkg-reconfigure console-setup

After starting console-setup, go through the different screens and confirm your new layout.

First, install the samba filesystem:

apt-get install smbfs

To manually mount a samba share:

mount -t  smbfs -o username=<username> //<servername>/<sharename> /mnt/point/

To have the samba share mounted during boot-time, edit fstab:

mkdir /mnt/<sharename>
vim /etc/fstab
//<servername>/<sharename>  /mnt/<sharename>  smbfs  username=<username>,password=<pwd>  0  0
