Black Screen between GRUB and Ubuntu loading screen

[antitoxic]

Hello,
I don't know whether it is a normal behaviour but the black screen from the moment that I press enter on GRUB to Ubuntu loading screen (dots, illuminated one by one in 10.04) is far more than the actual ubuntu loading.
Is it normal to have such long delay after the choice from GRUB to the Ubuntu loading screen ?

I will give you any debug data just tell me what I need to provide and if possible how.

I've got the same thing, have you got NVidia's official drivers installed?

nothing is perfect at time but:

sudo dpkg-reconfigure gdm
sudo dpkg-reconfigure plymouth

sudo dpkg --configure -a

might help a little

HI antitoxic

Theres a 10sec.timer in grub to let you enter at startup. Can be changed in grub.

Sorry I see your starting at selection of grub. I haven't seen grub in so long, I hardly see the dots any more. Start button till on Internet <20sec.

Hello,
@chriswyatt I have DELL laptop. I'm not using nvidia video card.
@dino99 It didn't change anything
@clhsharky I'm not talking about GRUB selection timeout.

I still have this huge amount of time where screen is simply black.
This time period starts after GRUB and continues up to the point the ubuntu logo shows up with the dots.
Ubuntu logo splashscreen is very quick (probably 2 seconds) and then the login screen.
The black screen period of time is in the period of 20-40 seconds.

I'm using a laptop with external monitor.
I found something out:
After GRUB main monitor is black, as if no output is fed to it (no active pixels), but the laptop monitor shows a blinking white underscore cursor?

Does any of this helps ?
My graphic card is the built in the DELL laptop: Intel 945GM

I am also having this problem as are folks in this thread:http://ubuntuforums.org/showthread.p...ight=long+boot

[antitoxic]

No, @andyanderso, it is not the same problem.
I have 20-30 seconds of blinking cursor after the grub.
They only thing enabled from my BIOS boot sequence is the hard disk.

[andyanderso]

Sorry...Thought it sounded similar enough to maybe combine forces...

I've read about the blinking cursor problem.
I don't have blinking cursor when I load Windows from GRUB.
This is my linux grub2 entry:

menuentry 'Ubuntu, with Linux 2.6.32-22-generic' --class ubuntu --class gnu-linux --class gnu --class os {
    recordfail
    insmod ext2
    set root='(hd0,6)'
    search --no-floppy --fs-uuid --set fb9d2ffc-6b70-404a-ad68-915f6e54db44
    linux    /boot/vmlinuz-2.6.32-22-generic root=UUID=fb9d2ffc-6b70-404a-ad68-915f6e54db44 ro  vga=795  quiet splash
    initrd    /boot/initrd.img-2.6.32-22-generic
}

Windows:

menuentry "Microsoft Windows XP Professional (on /dev/sda1)" {
    insmod ntfs
    set root='(hd0,1)'
    search --no-floppy --fs-uuid --set 9ce0fbc7e0fba624
    drivemap -s (hd0) ${root}
    chainloader +1
}

These are the auto-generated from grub2 entries. I haven't modified them

Does anyone know why does this blinking cursor appear ?

antitoxic,

I am experiencing exactly the same probleme as you:

My machine: Ibm thinkpad, T43p
I'm booting ubuntu linux lucid from external HD which is connected via usb.

Same as you:
After selecting linux boot kernel in grub boot menu (by hitting enter) there does not seem to happen anyting for about 10...15 seconds (though, the LED on the HD blinks, indicating some sort of activity....)

After that time, booting starts normally, however the graphical screen with the dots only appears shortly before the appearence of the authentication screen.

In /var/log/syslog nothing seems to indicate any problems regarding the kernel.

Karmic did not have this problem. It showed up only after upgrading to lucid.

Any new thoughts on this?

Regards
Hanspeter
