+# hidpi
+
+I recently installed on a laptop with a high DPI display.
+
+Turns out, the configuration needed numerous changes, which I will detail here.
+
+
+## compute DPI
+
+I recommend that you compute your DPI first.
+
+https://winaero.com/blog/find-change-screen-dpi-linux/
+
+
+## configuration
+
+First, for the openbox menu, conky, and others, changing `Xft.dpi`.
+
+For gnome based applications this is recommended:
+
+	gsettings set org.gnome.desktop.interface text-scaling-factor 2.0
+
+For `Sublime Text` you need to add `"ui_scale": 2.0` to user configuration.
+
+Finally, the scaling of `urxvt` makes the `urzvtq` dimensions a bit large, so I modify `geometry 200x24` to `geometry 200x16` inside `/usr/local/bin/urxvtq`.  _We rely on a width larger than the display to force Openbox to auto-shrink it._
+
+For the console displayed at boot, I ran `pacman -Syu terminus-font` and then modified `FONT=koi8u_8x16` to `FONT=ter-932n` inside `/etc/vconsole.conf`.  _I prefer `koi8u_8x16` aesthetically, but it is too small on large displays._
+
+To fix the cursor several files needed to be modified from `Chameleon-SkyBlue-Regular` to `Chameleon-SkyBlue-Large`.  _This includes `~/.gtkrc-2.0`, `~/.config/gtk-3.0/settings.ini`, `~/.icons/default/index.theme`, and `~/.Xdefaults`._

+# X1 Carbon
+
+I bought an X1 Carbon during their 2019 March sale; $2000 of laptop, $600 worth of upgrades, for $1500.
+
+I am transitioning from a 2015 12" Macbook; recent experience suggests Apple is going downhill.
+
+This is just a "scratch-pad" of things I experienced when I setup and began using the new machine.
+
+I am using [the wiki](https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Carbon) as a reference.
+
+
+## first impressions
+
+It is very small and light weight.  Possibly lighter than my 2015 12" Macbook.
+
+The display is absolutely gorgeous.
+
+The speakers are an unimpressive contrast to the display.
+
+The battery life, even (or perhaps especially) with Linux seems amazing.  I spent 3 hours actively configuring the system and it only went down 10%.  The initial calculation claimed 8 hours, which went up to over 11 hours due to averaging my activity and consumption.  _I have not yet tested this under load such as during compilation._
+
+Thus far I have not encountered a single show-stopper or complex issue with setting up Arch Linux on this laptop.
+
+The keyboard is going to take some getting used to, mostly due to layout, but also the functionality such as soft-enable/disable of things like bluetooth and wifi, **which are working out-of-the-box.**
+
+The HiDPI display has required quite a few configuration tweaks.
+
+Sleep mode appears to work out-of-the-box as well when I close the lid, and even automatically disables networking (which is re-enabled when the lid is opened), but I will have to check battery consumption.
+
+The trackpad works, but feels slow so I am looking to reconfigure it (_almost certainly related to hiDPI_).
+
+_The display brightness is the only thing I have found so far that is not working "out-of-the-box"._
+
+
+## second day
+
+I closed the lid at midnight with 89% battery, and opened it this morning after 9AM.
+
+The display came back on immediately, and the battery level was 86%.
+
+I did have to modify settings to address [hiDPI](hidpi.md) as many visual tools launched too tiny, others already scaled but were too big.
+
+I found that I had to increase mouse acceleration, which could be touchpad related, or due to the display dimensions.  _For my use case this involve changing `xset m 7 5` to `xset m 14 3` inside `~/.config/openbox/autostart`._
+
+I finished setting up `laptop-mode-tools` and some dependencies (eg. `acpid`).
+
+I began to discover some of the shortcuts thanks to [the arch wiki](https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Carbon_(Gen_6)).  For example, `fn+4` is instant sleep mode, and again to wake it back up.  The keyboard lighting is controlled with `fn+space`, meaning no extra work needed to get that working.
+
+**The only gripe I have so far is the lack of tap-to-click on the trackpad, and button placement throwing me off (I regularly rest my thumb where I expect buttons causing scrolling events).**
+
+I can also now confirm that the battery life is roughly half as good if playing media as opposed to editing files and browsing the web.  _4 hours of configuration, 9 hours in sleep mode prior to `laptop-mode-tools`, and another 4 hours of configuration and it still had over 50% battery, which listed as 6 hours remaining.  Then I began playing youtube videos and the calculation dropped to around 3 hours remaining._
+
+I was able to use the webcam and microphone with `guvcview`, I simply had to increase the microphone volume to get it to pick up the audio.
+
+**I was thrown off by the fact that I had to use `connmanctl` to run `enable bluetooth`, otherwise `bluetoothctl` does not see the controller.**  It might be possible to handle all connected devices entirely from `connmanctl` now.
+
+The system recharged its battery from 50% to 100% in just over 2 hours while in use.
+
+I had to add and modify a few configuration files to get brightness working as well as improved touchpad behavior.
+
+The display did accrue some smudges when I accidentally touched it, fortunately I had some cleaning cloths for that.
