To follow up on my original posting of this bug and Rocko's comments: 

I was successful in installing Ubuntu (11.04, 64 bit AMD version) using the USB 
stick. Once installed it seems to be working just fine with no other changes. 
Additionally, the B-Ray/DVD/CD drive appears to work as well.

@Benoit: Did you try the USB stick in the USB connector on the right- 
hand side? The ones on the left and back are USB3 and I think they do 
not work with the kernel on the installer. 

Also, once you have finished installing you may need to remove the 
nvidia driver manually. To do this, you should boot into recovery mode 
and do: 

sudo apt-get remove nvidia-current

and then reboot.

To update my previous comment: now that 11.04 is installed, everything 
is working nicely on the XPS15 now, including the CD/DVD reader and the 
USB3 ports (except watch out for the 2.6.39 kernel, which ironically 
comes with USB3 hub support but which also has a regression that means 
USB3 devices no longer work). I can use an HDMI monitor via a mini- 
display-port-to-HDMI adapter plugged into the mini display port. And 
nvidia card acceleration works if you install bumblebee (see 
https://github.com/MrMEEE/bumblebee).

Title: 
Ubuntu 11.04 fails to install on new Dell XPS-15 

Status in Ubuntu: 
New 

Bug description: 
Problem Summary: Unable to boot from 11.04 Ubuntu CD on NEW Dell 
XPS-15 Laptop. 

A few notes:

- The install CD does work on a HP Desktop (circa 2008 system). Therefore, CD 
image is good. 
- Ubuntu 10.10 CD also fails on Dell XPS-15 Laptop. 
- The Dell XPS-15 Laptop is brand new (April, 2011) (likely hardware changes 
since previous models). 
- ISO image on CD is: ubuntu-11.04-desktop-i386 using 
ubuntu-11.04-desktop-i386.iso.torrent 
- Also tried: 11.04 AMD64 version, and 11.04 AMD64 Alternate version. Same 
results. 
- Windows 7 (installed by Dell) works with no issues. 
- Failure is complete repeatable. 

Dell XPS-15 Laptop system details:

Processor: Intel Core i7-2620M 2.7 GHZ, turbo 2.0 up to 3.4 GHZ 
Memory: 8GB Shared Dual channel DDR3

HD = 640 GB, 7200 RPM SATA 
LCD: 15.6 FHD (1920x1080)

Dell calls this laptop a "XPS L502X" model.
