New Ubuntu 10.4 and black screen

[Pimpara]

I just installed Ubuntu 10.4 and nothing is coming up. After few seconds it shows Ubuntu and little red dots for a second or two and than my screen goes black.It remind me when I was on windows that laptop has virus or something. Is there a solution?

Hi again, Pimpara

I'll won't think much about the XP virus, and will try to install 10.04 again.

During install, take a while considering the partitioning options.
If you are new to linux, google for "partitioning linux hard drive"
but Linux Partition HOWTO, chapter 4 seems good enough

Do you have anything else on that laptop, or is it all for ubuntu?

If reinstalling doesn't work, we'll probably have to talk about your hardware

Try starting Ubuntu without the splash screen, when you restart the system hold down the shift key till the grub menu is displayed, select the top entry, press e to edit, remove the words quiet and splash then press ctrl+x to boot. This may fix the boot process & if it does not you can at least see messages displayed as the system starts to boot.

OK , I'm trying with GRUB thing. Top entry looks like this:
Ubuntu 10.04 LTS, kernel 2.6.32-22-generic. After E for edit I can only see
quiet on the botom ,when I erase quiet and press ctr+x nothing happens .
I'm wondering is it hardware like Luis said.

This is a somewhat common problem, usually related to your graphics card and kernel mode setting. (Which means the linux kernel is responsible for setting up screen resolution and depth. Previously, this was done by xorg.)

To the end of the boot line, try adding nomodeset or if that fails try xforcevesa.

This is what I have when I pres E on top kernel line:
uuid 16e6da70-15c1-49b0-904c-878e0475fc34
kernel /boot/vmlinuz-2.6.32-22-generic root=UUID=16e6da70-15c1-49b0-
initrd /boot/initrd.img-2.6.32-22-generic
quiet

I had to write everything just for you to have an idea what I see.
Now what?

[reed9]

It's the kernel line you want to add to. It looks like what you wrote is cut off. An example of a full line would look like

kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/884c1a88-ff73-47d0-97bc-2a8dc84b157a ro nomodeset

Well I tried and I had some more stuff show up on my screen but it just went black again.I even had check up of my hard drive and after that just black.
Now I guess I have to check my hardware like Luis said.
Is there a way to save my documents?

[reed9]

What OS did you have before installing Ubuntu? Normally, when installing a new OS of any sort, the harddrive gets formatted and anything on there is lost, except possibly to serious recovery tools.

If you have stuff on the drive and are able to boot up a live CD of any linux distro, you can transfer them to a flash drive.

Did you also try the xforcevesa option also?

[Pimpara]

I tried both options. After both there is a lot of text and numbers and few seconds later it looks like will come up but in half of a second a can see like rainbow colors ,similar like when you squish peace of paper and after that black. A video card maybe?
