Blackstart Screen

[flam]

Hello,

When I start my patched kernel from Ubuntu/Grub I get only a blackscreen. I get no messages about the system state. Is it possible to force linux to give me a echo. It would be helpfull if I no witch module cause the error (of course).

Are you using any option with kernel like quiet and wrong vga value?

Post the kernel line from /boot/grub/menu.lst file here.

Hi,

I haven't an menu.1st. I'm using the newest kernel. But I think the /etc/default/grub is the template for the "booting-file". Here the lines of this file:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=2
GRUB_HIDDEN_TIMEOUT=2
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=-1
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=" splash"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY="true"

I'm only change the Value of "GRUB_TIMEOUT" and "GRUB_HIDDEN_TIMEOUT_QUIET" so I always see the Bootloader-Menu.

Is there anything suspect in my file?

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Remove quite and splash.

GRUB_CMDLINE_LINUX_DEFAULT=""

Execute update-grub command to generate new grub.cfg file. Boot up new kernel and check where it get stuck.

Hello,

I set the value "GRUB_CMDLINE_LINUX_DEFAULT=""". So I can see some messages when I start my old kernel. But with my new kernel I see only a black screen.
Any other ideas?

Which Graphics Card do you have? Does new kernel boot up in command line mode?

[flam]

Hello,

In Commandline I've the same effect. I write the commands, put enter and get (immediatly) an black screen (without any message).
My Device Manager told me that I use an NV43GL [Auadro FX 550] from nVidia Corporation with an PCI-Connection.
Is it possible that my patch kill the support for this card?

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=" splash"

Have you removed splash keyword from GRUB_CMDLINE_LINUX=" splash" line too. Remove it and execute update-grub command again. Check the contents of /boot/grub/grub.cfg file.
There should be any option like splash or quiet in the kernel line of new Kernel.

Do you get into GRUB? Do you get any kind of shell?
