Linux Bug: Disable Framebuffer Nvidia free Driver Nouveau for hanging xserver-xorg (for Servers)

Problem: Nouveau the free Version of the Nvidia Display Driver crash if you switch to Console or kill the xserver-xorg.Its enabled by default inside the KERNEL!! this WAS NOT DEFAULT at last DECADES!! (DEBIAN 3.0-5.0 never used it!, cause bugs and hanging Servers)

Solution:

echo 'blacklist nouveau' > /etc/modprobe.d/blacklist-nouveau.conf

then edit with $sudo nano /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="noquiet nouveau.nomodeset=0"     #on Ubuntu set "nomodeset noplymouth"
...

update grub Loader with
sudo update-grub2

REMARK: THIS MUST BE USED AT SERVERS FOR STABILITY!! REMOVE / BLACKLIST ALL UNEEDED DRIVER MODULES LIKE SOUND!
(DISABLE ALWAYS UNNEEDED CHIPS AT YOUR BIOS AGAINST PROBLEMS AND ENERGY COSTS)

Ubuntu 10.04 Lucid Lynx Kiosk Mode

If you run your PC as Family PC for Kids or Public PC you have to make some changes:

Step:
– Setup Ubuntu 10.04 with alternate Disk!
– select XDM as Login Manager by default!!
– go /etc/init folder as root
– edit control-alt-delete.conf and disable reboot without login
– go /etc/acpi make chmod 000 on powerbtn.sh hibernation.sh lidbtn.sh to prevent unwanted shutdown
– make #sudo aptitude remove gnome-power-manager to prevent unwanted standby by all users
– test forced shutdowns pressing all buttons at menu
– optional add autologin at login manger for a user without „sudo“ rights
– optional add to startup the „opera -kioskmode“ Browser Command (fullscreen Opera to hide Desktop to prevent users to reach files on the system)

Ubuntu 10.04 Lucid Lynx disable hide REBOOT SHUTDOWN STANDBY SUSPEND GNOME SYSTEM MENU SECURE KIOSK MODE

Problem: If you install ubuntu 10.04 Desktop by default
every user can shutdown,reboot,hibernate or standby a PC

If you want to disable this make:
– install gdm2conf from the ppa channel to customize hide System Menu at Login GDM2 Manager
– create custom Gnome System Menu Policy against User shutdown,reboot,hibernate or standby.

Steps:
create new policy file:
#sudo touch /etc/polkit-1/localauthority/50-local.d/custom-menu.pkla

edit new policy:
#nano nano /etc/polkit-1/localauthority/50-local.d/custom-menu.pkla

insert into:
[Disable suspend]
Identity=unix-user:*
Action=org.freedesktop.devicekit.power.suspend
ResultActive=no
ResultAny=no

[Disable hibernate]
Identity=unix-user:*
Action=org.freedesktop.devicekit.power.hibernate
ResultActive=no
ResultAny=no

[Disable shutdown]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.stop
ResultActive=no
ResultAny=no

[Disable reboot]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.restart
ResultActive=no
ResultAny=no

reboot and try!

To disable CTRL-ALT-DEL REBOOT edit #sudo nano /etc/init/control-alt-delete.conf
comment out:
#start on control-alt-delete

#task
#exec shutdown -r now „Control-Alt-Delete pressed“

For high Security:
disable TTY Consoles 1-6 with edit /etc/init/ttyX.conf (Value of X = 1-6)
comment out:
#respawn
#exec /sbin/getty -8 38400 tty1

Change at rights of /sbin/reboot /sbin/halt /sbin/shutdown /sbin/poweroff
that shutdown or reboot the System to 0700 from Console (SSH)

If you can access the PC Case cut the Reset and Power Cable from Mainboard
fix the Power Cable at Wall and PC against cut off !! PC inside locked steel Server Rack!!
(used are cheap at ebay)

AFTER ALL of this you can only reboot/shutdown with #sudo reboot or #sudo init 0!
