Below is a list of how I configured my laptop. Most is personal preference, some settings might affect more users. Maybe someone find it useful.
I use the XPS 15 9550 in the maxed-out configuration.
- Intel i7-6700HQ
- 32 GB DDR4-2133MHz
- 4K (Ultra-HD) Display
- 1 TB SSD (Toshiba)
Previously, I’ve had Linux Mint 18.3 installed, together with Windows 7 in a dual-boot configuration. I’ve made a mistake during the Manjaro setup and accidentally overwritten my /boot partition.
So after the installation finished I couldn’t boot Windows anymore, but that could be fixed by calling some Windows repair commands. Unfortunately, they can only be called from the Windows Setup. So you need a bootable USB stick with Windows 7 setup files. Windows 7 can only be installed when your disk is set to AHCI mode in the BIOS. I’ve created my USB stick via Rufus. Make sure you choose “GPT partition for UEFI”. Afterwards, I also needed some drivers for the SSD, in my case Toshiba OCZ. They need to be integrated into the setup files before continuing (I’ve used DISM GUI to do it), otherwise Windows Setup won’t find your disk.
When Windows setup is started, execute these commands:
Bootrec /fixmbr Bootrec /fixboot Bootrec /rebuildbcd
For some reason I had to call them a couple of tries until the files in /boot/efi/EFI/Microsoft/Boot/ were recovered, not sure why.
Important: You need to boot from the USB stick via EFI. If you boot in legacy mode, Windows Setup will complain that the installed version is not compatible.
Linux is still a big pain when it comes to out-of-the-box support for HiDPI displays, which are too common nowadays to not care about them. Linux is lacking behind in this regard and I don’t understand why I have to run any of the commands below manually. :(
Grub is really old and has 1500ms reaction time when used on a 4K screen. :/ However, until I get EFISTUB to work I have to use it. Fonts are too small by default, this can be fixed by calling:
sudo grub-mkfont --output=/boot/grub/fonts/DroidSansMono32.pf2 --size=32 /usr/share/fonts/TTF/DroidSansMono.ttf
Then, edit or create an entry in /etc/default/grub:
Theme: I use ooxxvv/basil-tw
To install it, extract all files into /usr/share/grub/themes/basil-tw and change the line:
If all configuration is done, run
grub-mkconfig -o /boot/grub/grub.cfg.
LightDM Login Screen
I’ve changed the following two lines in /etc/lightdm/lightdm-gtk-greeter.conf:
background = /usr/share/grub/themes/basil-tw/background.png theme-name = Adwaita-dark
Maybe controversial, but I like to disable all hacky tries to fix something in software which is actually broken in hardware. More and more vulnerabilities come up. All of them slow the CPU down. No widespread attacks are happening.
I don’t see a reason to drop 30% in performance when the worst attack case is someone’s leeching my memory at 5 kbit/s.. I’m not a data center, so I think it is very unlikely I’m gonna suffer from these attacks.
That’s why I have these options in my /etc/default/grub
GRUB_CMDLINE_LINUX="noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off"
Update: There is now a website which provides the best kernel parameters to speed things up: make-linux-fast-again.com. Notice the new
mitigations=off parameter, which was introduced in Kernel 5.2 and should disable all “security fixes”.
Open Settings Manager → Appearance → Fonts (in German it’s Einstellungen → Erscheinungsbild → Schriften) and overwrite the DPI value (I set mine to 192).
Add to ~/.profile:
export GDK_SCALE=2 export GDK_DPI_SCALE=0.5
You can open the Linux console if you press CTRL+ALT+F2 (go back to graphical UI: CTRL+ALT+F7). To make fonts bigger here as well, make sure you have the font inside /usr/share/kbd/consolefonts/ and edit or create the file /etc/vconsole.conf:
KEYMAP=de-latin1-nodeadkeys FONT=ter-132n FONT_MAP=8859-2
(Choose your own Keymap of course.)
By default, Manjaro has this weird collapsible terminal. I don’t like it too much, so I’ve decided to change it back to classic mode. Therefore, I’ve rebound the CTRL+ALT+T shortcut to xfce4-terminal.
Unfortunately, the old xfce4-terminal works poorly with GDK_SCALE and GDK_DPI_SCALE. Fonts looks blurred, and I hate it. I’ve managed to work around that by creating a file at ~/terminal.sh:
GDK_SCALE=1 GDK_DPI_SCALE=1 xfce4-terminal
chmod +x ~/terminal.sh and bind the shortcut to the terminal.sh.
This way, the GDK variables are set for all other programs but xfce4-terminal.
It’s super-ugly, but it works well for me.
Fish is my favorite shell. I love the autocompletion features. To install it, run:
pacman -S fish chsh -s /usr/bin/fish
To install custom themes and much more, I use Oh-My-Fish:
curl -L https://get.oh-my.fish | fish
My favorite theme is eclm, it shows a success flag of the last command, the current git branch and if there’s any changes on your current branch:
omf theme eclm
pacman -S autojump
Edit ~/.config/fish/config.fish and append:
begin set --local AUTOJUMP_PATH /usr/share/autojump/autojump.fish if test -e $AUTOJUMP_PATH source $AUTOJUMP_PATH end end
Bluetooth was enabled by default on each boot, which I don’t like. To disable it, append the following line to /etc/rc.local
rfkill block bluetooth
Check it worked by calling
rfkill list, which should state hci0 is soft-blocked.
Graphic card drivers, ACPI
Block Nouveau (Nvidia driver)
Create a file /etc/modprobe.d/blacklist-nouveau.conf with the content:
blacklist nouveau options nouveau modeset=0
Disable the Nvidia GPU completely (this will save power, see below), create two services:
[Unit] Description=Power-off dGPU After=graphical.target [Service] Type=oneshot ExecStart=/bin/sh -c "echo '\\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call; cat /proc/acpi/call > /tmp/nvidia-off" [Install] WantedBy=graphical.target
[Unit] Description=Power-off dGPU after resume from suspend After=suspend.target [Service] Type=simple ExecStart=/bin/sh -c "echo '\\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call; cat /proc/acpi/call > /tmp/nvidia-off" [Install] WantedBy=suspend.target
I personally like i3lock-color, called with these settings:
i3lock --clock --blur=6 --radius=400 --timesize=100 --datesize=100 --timepos="w/2:h/2+70" --datepos="w/2:h/2-80" --datestr="%Y-%m-%d" --datecolor=ffffffff --timecolor=ffffffff --ring-width=20 -i /home/neonew/i3lock/lockscreen.png -t -n
lockscreen.png is just a one-pixel file, which has the alpha value set to 0.75 (to darken the screen).
Don’t really know what it is, but Visual Studio Code and IntelliJ needs this value increased in /etc/security/limits.conf (add these lines):
* soft nofile 380180 * hard nofile 380180
Disable grouping in the panel: Right-click empty space in the panel, Panel > Panel Preferences > Items > select “Window Buttons” > Edit the currently selected item (a button on the right side) > Behaviour > Window grouping: Never (source)
I use the font
Source Code Pro Regular in 11pt.
I use the orangish color scheme. Put it in ~/.local/share/xfce4/terminal/colorschemes/.
Most of it was created by Mervyn McCreight, thanks dude.
For Autostart, create a file ~/.config/autostart/conky.desktop
[Desktop Entry] Type=Application Name=conky Exec=conky --daemonize --pause=5 StartupNotify=false Terminal=false
Package manager for AUR
I like to use yay.
One adjustment: In /etc/makepkg.conf I’ve set
PKGEXT='.pkg.tar' to improve the build speed.
Otherwise it tends to spend a lot of time in the “Compressing…” step.
I like to use Microsoft Code, in the open-source variant.
My favorite shortcuts:
- q: Quit
- m: Mute
- #: Cycle audio streams
- s: Screenshot
- f: Fullscreen
- , / .: Next/Previous frame
- Ctrl+H: Toggle hardware acceleration
Hardware acceleration: The mpv team thinks it’s “usually a bad idea unless absolutely needed”, but if you ask me, it saves CPU power and battery, so it is important to me.
hwdec=vaapi to ~/.config/mpv/mpv.conf. (source)
The only thing it’s missing is a nice overlay to see all possible shortcuts. See this issue (they think it’s low prio, well..).
Chromium keeps asking me for the password of the default keyring. I’ve never set it up and don’t really know about it. The bad thing is, every time Chromium gets updated, it loses all of my stored passwords if I don’t enter the keyring password.
Therefore, I’ve decided to store them in plaintext in my user directory. This might not be recommended, but I prefer to not be annoyed on every update.
I also use multiple profiles, and Chromium remembers the last used profile. So when you boot your system and start the first Chromium instance, the last used profile is loaded automatically. I like to use my personal profile on every fresh Chromium instead.
For blocking ads I use uBlock Origin.
I prefer to pay or donate to services I like.
Quick tip to make
git gui and
I got the error message
/usr/lib/git-core/git-gui: Zeile 10: exec: wish: Nicht gefunden.
This is caused by the missing program wish, which is part of the package tk.
Then it starts, but complains about a missing spelling check file. This can be fixed by installing aspell-de (change accordingly for your language).
sudo pacman -S tk aspell-de
git log --pretty=format:'%C(yellow)%h %Cred%ad %Cblue%an%Cgreen%d %Creset%s' --date=short

When the laptop was idling, I had a power consumption of ~13 W.
(According to /sys/class/power_supply/BAT0/current_now)
With the Nvidia GPU disabled, it was reduced to 6.5 W.
(In both cases connected to WiFi, lowest brightness).
