I have a new machine with a MSI N560GTX Ti Twin Frozr II/OC graphic card and MSI PH67A-C43 (B3) main board. If i install the current nvidia restricted driver and reboot the machine on Natty (64-bit), then i only get a black screen after reboot and my system does not respond. I can´t see the login screen.

On nvidia web page i saw that the current driver is 270.41.06. Is that driver used as current driver?

Btw, i am an ubuntu/linux beginner and therefore not very familiar with ubuntu. What can i do to solve the black screen problem?

EDIT: Setting the nomodeset parameter does not solve the problem. After ubuntu start, first i see the ubuntu logo, then strange pixels and at the end the black screen. HELP!

EDIT2: Thank you, but setting the "video=vesa:off gfxpayload=text" parameters do no solve the problem too. Same result as in last edit. HELP. I would like to see Unity. This is my grub:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="video=vesa:off gfxpayload=text nomodeset quiet splash"
GRUB_CMDLINE_LINUX=" vga=794"

EDIT3: I dont know if it is important. If this edit is unnecessary and helpless I will delete it. There are some log files (Xorg.0.log - Xorg.4.log). I dont know how these log files relate to each other. Please, check the errors listed below.

EDIT4 There was a file /etc/X11/xorg.conf. As fossfreedom suggested I executed

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

However, there is still the black screen after reboot.

EDIT5 Neutro's advice (reinstalling the headers) did not solve the problem, too. :-( Any further help is appreciated!

EDIT6 I just installed driver 173.xxx. After reboot the system shows me only "Checking battery state". Just for information. I will google the problem, but help is also appreciated! ;-)

EDIT7 When using the free driver (Ubuntu says that the free driver is in use and activated), Xorg.0.log shows the following errors:

EDIT8 In the meanwhile i tried to install WIN7 64 bit on my machine. As a result i got a BSOD after installing the nvidia driver. :-) For this reason i sent my new machine back to the hardware reseller. I will inform you as soon as i have a new system. Thank you all for the great help and support.

EDIT9 In the meanwhile I have a complete new system with "only" a MSI N460GTX Hawk, but more RAM. The system works perfect. :-) The original N560GTX had a hardware defect. Is is possible to close this question? THX!
