Blank Screen on HP Pavilion DV6

I was able to fix the blank screen problem with the nomodeset option while booting. I was taken to the desktop where it finished the install for when you first boot up Ubuntu.

Then is restarted my computer and I set the nomodeset option again, but this time for some reason it's hanging up during the start up. More specifically it stops right after the checking battery status. I can't seem to get it to go any further than that even if I try to wait it out.

Does it have hybrid graphics like in Bug #813809
If fglrx was activated on installation rather try open source radeon driver. Currently some newer ati cards have issues with fglrx driver.

Investigate dmesg.
dmesg | tail

Disable 'quiet splash' in grub in case to get some hints.

I deleted quiet splash from the grub and replaced it with nomodeset and then it launched the desktop and went through the final installation before it restarted. At that point, I tried to do the same thing and it got stuck at the start up. I am going to be honest and say that I am not very good with this kind of stuff.

But I do believe it's a hybrid graphics card. I am currently looking at a menu that assigns high performance to some applications and not to others, wouldn't that mean it's hybrid?

I uninstalled Ubuntu from my computer, because some guides were saying that you have to get the settings right from the beginning. So if I have the installation disc that I created, what is the best way to go about reinstalling Ubuntu?

P.S. I am not totally new to Ubuntu, I had it on my old laptop and never had a single installation problem. So I never had to change any settings for it, therefore I never learned how to do so.

Thank you.

What GPU do you use?

I am using an graphics card that came with my computer. It's an AMD Radeon HD 6620G with 1GB of dedicated RAM for grahpics.

Try the boot option:

nomodeset

Thanks

As stated above, I've already tried that option. I was able to get it to boot up for the first time. It went through finalizing the installation and rebooted without a single problem. Then it rebooted the computer and it froze at the Checking Battery Status Screen.

I wasn't able to get it any further than that, even after another reboot and another reboot. As said above, it's most likely due to the fact that I have a hybrid graphics card(or at least I think I do), so I am going to reinstall and see what I can come up with this time.

As in bug report find out by e.g.

lspci -v | grep -A 12 VGA

or
sudo lshw -C video

Verify unity support:
/usr/lib/nux/unity_support_test -p

Hi,

I have the HP Pavilion G6-1250ss A4-3300M/4GB/500GB/15.6" with ATI Radeon HD 6480G;

I have resolved this problem installing the ati drivers from ati web in ubuntu 11.10;

http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx

A better solution:

changing this in /etc/default/grub.conf

- GRUB_CMDLINE_LINUX_DEFAULT="splash quiet nomodeset"
+ GRUB_CMDLINE_LINUX_DEFAULT="splash quiet acpi_osi=Linux acpi_backlight=vendor"

run "sudo update-grup2" and reboot

and i get accelerated graphics.

except change:

"sudo update-grup2"

to

"sudo update-grub2"

Obviously run without the quotes.

On a Hewlett-Packard Pavillion dv7-4285dx with dual Intel/AMD that experienced this problem in Ubuntu 12.04 with kernels built from kernel.org sources (as opposed to coming from Ubuntu) starting around linux-3.2 (64 bit kernels and 32 bit user space), the problem disappeared when the computer was upgraded to Ubuntu 12.10.

I know this is an old post but I have the HP Pavilion dv6-6c11nr Entertainment pc with the A4 vision. I was haveing the same problem as you, couldnt get past a black screen then I tryed the ( delete quiet spash ) and replaced with ( nomodeset ) then with (radeon.nomodeset=0) and notta.....I did try putting in "i915.modeset=0" and still notta . I tryed all the posts I could read, i was thinking this pc just couldn't run Ubuntu 12.10 So what I did to get past this was I put in "radeon.nomodeset=0" in between quiet & splash it looked like this.....

Old line:
 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" --

New Line:
 GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.nomodeset=0 splash --"

It wouldn't work with out having the (quiet) in the front and the (splash --) at the end

I tryed to put radeon.nomodeset=0 in front, behind, and by its self but when I put it in the middel it worked just fine. not sure why but it did the trick for me. So if anyone has this pc it mite work for you too

Oh and by the way, Im now running Ubuntu 13.04 and its runing like a champ......
