10.04 LTS RC: Blank Screen at startup

well,

I have come further than I had in my previous post in this thread...
and i thought it was going to work this time.... but no go... lol

All goes fine, and I get to the point where you can " try ubuntu" or "install ubuntu".

So I choose "try ubuntu" ... and it acts like it is going to work....
the loading screen comes up.....

then, my screen goes black,
but this time.... on the top half of my monitor...
it starts blinking, with white vertical stripes going across the black screen (only top half though)..
and It just keeps doing this,

anyone else experiencing that? if so...
How does one get around that? lol

Update:
I booted from the cd, pressed F6 and then selected the Nomodeset option. The install proceeded without any problems. However I am back with a blank screen with a monitor message that the video mode cannot be displayed. This is true even if I select the recovery option at boot. Now I am stuck.

Any Ideas??

I have been able to boot into my computer with accelerated graphics using an older kernel. To this point, it seems that the kernel could have some issue.
I also noticed that xorg.conf had been renamed to xorg.conf~. Does someone know if that is to be expected? Does Lucid use some other way for configuring X?

Eureka !!

I have a HP Pavilion SLimline s7727c

with lspci giving me
VGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2)

I was getting a blank screen (out of sync) on booting from the live cd.

I worked around the problem as follows:

• At install screen press F6 and select nomodeset and install Ubuntu as usual.
• On first boot after install, press e on getting the GRUB bootloader.
• Using arrow keys navigate to and delete quiet and splash and type the word nomodeset in their place
• Press Ctrl and X to boot
• You should now be able to login to your Ubuntu as usual

For those of you who do not know what to do next, in the taskbar click on System->Administration->Hardware drivers, and select and activate the nvidia current driver if you have an nvidia card like I do. The driver will be downloaded and activated automatically, and you will be prompted for a reboot.

Perfectly brilliant!

Thank you nucleuskore! That worked for getting me into the desktop. Currently installing the restricted driver (have an Nvidia 9600GT). Here's hoping for proper working boot after this update.

Thanks!

Thank-you nucleuskore! It worked like a charm! I really appreciate it! (1440x900 display here with an old Nvidia Geforce 4)

Update - now have final version of 10.04LTS. This is for people with issues with ATI GPU and blank screens (no signal) on boot up

Same issue blank screen after initial boot screen HOWEVER

- switched to DVI connection instead of HDMI and it boots fine
- installed restricted driver for ATI
- reboot
- switch back to HDMI connection only

All is well, no more blank screen on boot up and restricted driver working well without any issues.

Woohoo

:P

Just to confirm what jaycee said about newer ATI cards.

Using an ATI 5870 and two monitors had the same problem.

After trying with just one monitor in a specific dvi port the live cd booted correctly.

So thanks for the advice folks, you're life savers! :)

Course at the moment I'm only assuming once I install this holds true and that changing to the proprietary ATI drivers will get me back to two monitors.

When I get chance to install later I'll edit here to confirm or not.

Confirmed

nukleuscore. You are great.

No I am not great. I am happy to be of some help to you and all who benefited from this little insight. It is however quite annoying to see things like this
