How to install Ubuntu 17.04 on Dell XPS 15 9550

I had some trouble installing Ubuntu 17.04 to dual-boot with Windows 10 on my Dell XPS 15 9550, so documenting here in case it helps others...

Once I got Ubuntu installed, it runs well. I'm using the NVIDIA proprietary driver, and I've had no major issues with hardware yet so far.

Most of the installation hurdles for me were caused by Ubuntu not being able to see the disk drive while it was operating in Raid mode, and UEFI/Secure Boot seemed to block the install somehow.

The trick to getting past these hurdles was to set Windows to boot into Safe Mode and then switch the disk drive to AHCI and disable UEFI in the BIOS before booting back into Windows in Safe Mode, and then switching Windows back to non-Safe Mode.

I found rcasero's notes on installing Ubuntu on Dell XPS 15 9560 useful.

Detailed steps to install...

1. (If your Windows partition is encrypted, print out a copy of your BitLocker key. You'll need to enter this on boot after changing anything in your BIOS.
2. Boot into Windows 10.
3. I also needed to resize my main Windows partition from inside Windows; the Ubuntu installer seemed unable to cope with resizing my encrypted Windows partition for some reason. You can resize your main Windows partition using Windows' "Create or edit Disk Partitions" tool.
4. Configure Windows to boot into safe mode: Press Win+R and run msconfig.exe > Boot > Safe Mode. Reboot.
5. Press the F12 key while the BIOS splash screen comes up. Just repeatedly pressing it while the machine is booting seems to be the most reliable tactic.
6. In the BIOS menu, BIOS Setup > System Configuration > SATA Operation, change "RAID On" to "AHCI".
7. In the BIOS menu, disable Secure Boot.
8. Reboot into Windows. You'll need to enter your BitLocker key to unlock the drive since the BIOS changed. Windows will boot into Safe Mode. If you don't have your Windows install set to boot into Safe Mode, you'll get a BSOD.
9. Once you've booted into Windows Safe Mode, you can configure Windows to boot in normal (non-Safe Mode) with msconfig.exe > Boot > Safe Mode again.
10. Reboot with your Ubuntu USB Live Disk inserted, and press F12 while booting to select to boot from the Live USB disk.
11. The rest of the install Just Worked.
12. Once you've installed Ubuntu, for better reliability and performance, enable the proprietary GPU drivers, in System Settings > Software and Updates > Additional Drivers. I enabled the NVIDIA and Intel drivers.
13. I've found the touchpad often registers clicks while I'm typing. Turning off System Settings > Mouse and Touchpad > "Tap to click" fixed this and gives pretty good touchpad behaviour.
14. Firefox by default has its hardware accelerated layers disabled, but force-enabling it seems to work fine. Open "about:config" in Firefox, and toggle "layers.acceleration.force-enabled" to true. Restart Firefox.

Enabling external monitor on Lenovo W530 with Nvidia Discrete Graphics and Ubuntu Linux 12.04

I've recently acquired a Lenovo W530 laptop. It's nice. Running Ubuntu 12.04 and with 32GB of RAM and an SSD it builds Firefox with cold/empty caches in 14 minutes flat, which is pretty good!

It was a trial figuring out how to get the Nvidia graphics card and a second monitor working however. The current Ubuntu stable nvidia-current package doesn't include support for the Quadro K1000M chipset, and the official Nvidia drivers available from Nvidia.com didn't work for me, and left my libGL.so's missing when I uninstalled them.

I eventually figured out the steps to get a compatible Nvidia driver installed and displaying a second monitor:

1. Install the "X Updates" team's PPA, and install the latest Nvidia drivers, which supports the Quadro K1000M. In the terminal enter:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

2. Reboot. At the Lenovo BIOS screen press "Enter" to interrupt normal startup, F1 to enter BIOS setup utility. Change Config > Display > Graphics Device to Discrete Graphics. This means the hardware will attempt to use only the Nvidia graphics card, not the Intel integrated graphics. Press F10 to save and boot the computer.

3. Once you've booted up and logged in, to setup multiple monitors you'll need to run nvidia-settings from the terminal as root:

sudo nvidia-settings

Setup your displays in the "X Server Display Configuration" tab (you may need to "Detect Displays" first, and you probably want "TwinView" configuration). Once you've configured your displays, make sure you "Save to X Configuration File". When I saved my config file the path save was blank. If this happens to you, enter: /etc/X11/xorg.conf

3. (Updated 13 October 2012) Once you've booted up and logged in, you can use Ubuntu's "Displays" application to easily configure your secondary displays. Note that if you use nvidia-settings to write an xorg.conf (as I previously suggested) X won't detect when you unplug a monitor, and so when you unplug a monitor X may open windows on the monitor which is no longer connected, i.e. where you can't see them, which can be very inconvenient!

4. To get your hardware brightness keys working (i..e Fn+F8/F9), edit the /etc/X11/xorg.conf file as root:

sudo gedit /etc/X11/xorg.conf 

...and add the following line to the "Device" section for the "Quadro K1000M":

    Option         "RegistryDwords" "EnableBrightnessControl=1"

Log out/log back in and then your brightness keys should work!

4. (Updated 13 October 2012) To get your display brightness keys working (i..e Fn+F8/F9) you need to tell the Nvidia graphics driver to enable the brightness controls.

These days X automatically configures itself, so you can't just edit the xorg.conf file, you instead need to add a section to a file in /usr/share/X11/xorg.conf.d/ and X will include that section in the configuration that it automatically generates.

So to get the screen brightness keys working with your Nvidia graphics card, create a file in the xorg.conf.d directory, e.g:

sudo gedit /usr/share/X11/xorg.conf.d/10-nvidia-brightness.conf

Paste the following into the file:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "Quadro K1000M"
    Option         "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Log out and log back in, or reboot, or simply kill X with CTRL+ALT+BACKSPACE, or ALT+PrtSc+K, and your brightness keys should now work!

Caveat: I've only had a second monitor working on my VGA output, I'm looking forward to my mini-DVI adapter arriving so I can have a cripser DVI output. Hopefully that will Just Work....

Update 13 October 2012: a second monitor Just Worked with my mini-DVI adapter. I was able to get two external displays running off a docking station. Possibly the docking station could drive more, I haven't felt the need, three displays is enough for me!

And unfortunately my laptop refuses to boot with Discrete Graphics enabled, the Nvidia driver installed, and with virtualization enhancements enabled in the BIOS. Apparently it is possible with the help of the BumbleBee project however.

Update 13 October 2012: I was able to boot with virtualization enhancements enabled in BIOS if I specified the nox2apic kernel command parameter. I haven't done enough research to figure out whether disabling x2apic is a good idea or not.
