Fedora 17, Virtualbox & multi-monitor

Issue 1:
Well I wanted to mount shares
E:/Nexus
E:/Download
to a Fedora 17 guest. I succeeded by modifying my /etc/fstab:

#
# /etc/fstab
# Created by anaconda on Sat Jun 16 19:29:14 2012
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/vg_katyrvm-lv_root /                       ext4    defaults        1 1
UUID=1c638e90-e6d7-4fcf-ac85-d415dd8d68fc /boot                   ext4    defaults        1 2
/dev/mapper/vg_katyrvm-lv_swap swap                    swap    defaults        0 0
Nexus   /home/strayfire/Documents/Nexus                    vboxsf    defaults        0 0
Download   /home/strayfire/Documents/Download                    vboxsf    defaults        0 0


But strangely I get this error on boot:



If I press Control-D it works just fine... how strange.

Issue 2:
Multi-monitor in LXDE under Virtualbox.

I get two identical displays (mirror). I want them to display two separate things each. Eg. 1 full screen Firefox + 1 full screen LibreOffice (extended/span mode) rather than both screens showing the same Firefox window.

I'm assuming LXdisplay won't help me here...

FYI: LXdisplay detects them as two separate displays, which is nice because Fedora 15 doesn't, it sees them as one and the same.

So I changed my Xorg.conf from

# VirtualBox generated configuration file
# based on /etc/X11/xorg.conf.

Section "Monitor"
  Identifier   "Monitor[0]"
  ModelName    "VirtualBox Virtual Output"
  VendorName   "Oracle Corporation"
EndSection

Section "Device"
  BoardName    "VirtualBox Graphics"
  Driver       "vboxvideo"
  Identifier   "Device[0]"
  VendorName   "Oracle Corporation"
EndSection

Section "Screen"
  SubSection "Display"
    Depth      24
  EndSubSection
  Device       "Device[0]"
  Identifier   "Screen[0]"
  Monitor      "Monitor[0]"
EndSection


to

# VirtualBox generated configuration file
# based on /etc/X11/xorg.conf.

Section "Monitor"
  Identifier   "Monitor[0]"
  Option         "Primary"    "false"
  ModelName    "VirtualBox Virtual Output"
  VendorName   "Oracle Corporation"
EndSection

Section "Monitor"
  Identifier   "Monitor[1]"
  Option         "Right" "Monitor[0]" 
  Option         "Primary"    "False"
  ModelName    "VirtualBox Virtual Output"
  VendorName   "Oracle Corporation"
EndSection

Section "Device"
  BoardName    "VirtualBox Graphics"
  Driver       "vboxvideo"
  Identifier   "Device[0]"
  VendorName   "Oracle Corporation"
EndSection

Section "Screen"
  SubSection "Display"
    Depth      24
     Modes           "1920x1080"
     Virtual          3840 1080
  EndSubSection
  Device       "Device[0]"
  Identifier   "Screen[0]"
  Monitor      "Monitor[0]"
EndSection


based on this advice:
http://en.gentoo-wiki.com/wiki/X.Org/Dual_Monitors

but got absolutely no response from Fedora.

Do I need to configure Xinerama or something apart from the regular?

  2. The problem doesn't seem to come up now. Very strange... :/ No matter...

    Now I need to amend the dual-display problem. It's difficult even when I'm not in a VM. Never managed to solve it.

    Edit: The installation exploded somehow. Now it shows a similar error message despite the measures I have taken...
  3. Just so I understand here, do you have two physical displays which you're trying to get VB to use when you run in full screen mode or do you have two virtual displays on one larger screen?
  4. I can get VB to use two physical screens but they show the same thing. I want them to be able to show seperate things.
