I just bought a HP DV6 6011tx (link) Laptop. I formated the disk through Windows and prepared for installing Ubuntu. But when I inserted the live CD, it showed the Ubuntu start screen and then everything went black. There was no cursor, everything just stayed black like the screen was switched off (but the system is running).

When I tried to install from the USB, it said Live media is not found. Sometimes it also gave me a black screen like the CD. Does anyone have any idea how to fix this?

Thanks!

Try the alternate CD, it has non graphics installer. –  enzotib Jun 27 '11 at 7:49
    
try redownloading the iso image and burning it again. and see if it works. try loading a different OS and see if the same thing comes up if its same see maybe there is smthn in the bios. hope this helps. –  Vitaly Jun 27 '11 at 13:57

I had the same problem with my HP Envy 14.

Press any key when the small logo appears at the bottom to enter the advanced start page. Then press F6 for other options (but don't select anything), press Esc to return to the Boot Options line. There you should add radeon.modeset=0

Now you can install Ubuntu and as soon as the screen goes dark simply press the brightness key F3.

Worked for me :)

This solved my issue with my HP DV6. What gave you the indication to do this? –  Russell Myers Jan 11 '12 at 23:04
    
note that if you modified your function keys so the default is a function key rather than the extended hp functions, you will need to press fn+F3. I wasted 20 minutes because I stupidly forgot I had done this. –  jkhouw1 Dec 2 '13 at 6:52

I suggest you use the alternate installation. In the options screen, press F6 to add further Linux boot parameters and add acpi=off.

Press the brightness key on your computer which is F3. The problem is the brightness is so low that it's off.

Option 1: (issue with USB)

Insert USB stick, and reboot laptop.

Stop the boot (at BIOS logo), with Esc (or as prompted), and select USB as boot source.

If Ubuntu install immediately stops with error, type help Enter; wait 4 seconds, then press Enter.

If that fails, then try ..

Option 2: (issue with GUI install)

Use the 'Alternate install CD (on CD or USB) instead ..

http://www.ubuntu.com/start-download (location near you)

Then your PC should tell you what the issue is, instead of just stalling ..
