XPS 13

From stacky wiki

Natural scrolling

Tried installing ubuntu tweak, then doing setting Tweaks > Miscellaneous > Natural Scrolling to "on". Apparently, this simply modifies ~/.Xmodmap to be

pointer = 1 2 3 5 4 6 7 8 9 10 11 12

where the reversed 4 and 5 indicate that up and down scrolling is reversed. However, this doesn't reverse scrolling in nautilus or the package manager. See this bug.

Instead, trying the approach suggested in this comment. Since /etc/X11/xorg.conf.d didn't exist yet, I made it first.

sudo mkdir /etc/X11/xorg.conf.d
sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf /etc/X11/xorg.conf.d/
sudo vi /etc/X11/xorg.conf.d/50-synaptics.conf

Then added the following line to the touchpad catchall inputclass:

Option "VertScrollDelta" "-25"

The number 25 was obtained using xipnput as described here. First do

xinput list

to find the id of the Cypress trackpad (in my case it's 12), and then

xinput list-props 12 | grep "Scrolling Distance"

After logout and login, seems to work great!

Windows refund fail

Used Dell's customer care form with the following message.

Dear Dell,
I recently purchased the XPS 13 (Dell Purchase ID: 2003146435039). It arrived today, and I love it! Unfortunately, you only offer the XPS 13 preloaded with Windows 7. I downloaded and read the Windows 7 Home Premium OEM pre-installed EULA: http://download.microsoft.com/Documents/UseTerms/Windows%207_Home%20Premium_English_f3fcb9dc-3b69-4a18-ae3c-7d7bede82812.pdf
It said that if I do not agree to the terms, I should not use the software, and contact you regarding a refund for the unused operating system. I documented the unboxing and first boot of my XPS 13 here: https://picasaweb.google.com/112769623612714330777/DellXPS13firstboot# As you can see, I never booted the pre-installed operating system, and immediately installed the image of your very own Project Sputnik, which the computer is now happily running.
Please let me know if you require any additional information to provide me with a refund.
Best,
Anton Geraschenko

Disable bluetooth on startup

[1] Edit /etc/rc.local, adding

rfkill block bluetooth

just above exit 0. Seems to work great.

Correct brightness on startup

[2] Edit /etc/rc.local, adding this before exit 0:

echo 5 > /sys/class/backlight/acpi_video0/brightness

Okay, that didn't work [edit: nevermind; it seems it does work]. Trying the solution here. Editing /etc/default/grub to change the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

then executing

sudo update-grub

That works, but then I can't adjust brightness once I've started up. :-(
