Troubleshooting

Increase Failed auth Lockout Attempts

Manjaro will lockout a user for 10 minutes on 3 failed password attempts over 15 minutes.

Expressed as sudo not working with valid password or unable to login to the system.

/etc/security/faillock.conf

0644 root:root

deny = 5
fail_interval = 300
unlock_time = 600

Application Scaling

High DPI monitors require custom scaling settings.

⌘ ➔ system settings ➔ display and monitor ➔ display configuration

Global scale: 150%
Legacy applications (X11): Apply scaling themselves

Fonts look fuzzy

Fonts may not support subpixel hints or it may be disabled.

Copy custom fonts to system.

# Requires reboot if not manually loaded in Font Manager.
cp {FONTS} /usr/share/fonts
systemsettings kcm_fontinst  # Font Manager in GUI.

Tweak font display for LCD's if display is still not clean.

/etc/fonts/local.conf

0644 root:root

<!DOCTYPE fontconfig SYSTEM "fonts.dtd">

Xft.antialias: 1
Xft.hinting: 1
Xft.autohint: 0

Merge settings, link additional profiles, and update cache.

xrdb -merge ~/.Xresources
ln -s /usr/share/fontconfig/conf.avail/10-sub-pixel-rgb.conf /etc/fonts/conf.d/
ln -s /usr/share/fontconfig/conf.avail/11-lcdfilter-default.conf /etc/fonts/conf.d/
fc-cache -f -v

Caps lock as Control

Override caps lock for keyboards that do not remap caps lock key.

/etc/default/keyboard

0644 root:root

XKBOPTIONS="ctrl:nocaps"

For current session.

localectl set-x11-keymap us pc105 ,query ctrl:nocaps

Reboot to apply.

Manjaro Updates Consistently Fail

Last update was more than six months ago and keys are expired.

/etc/pacman.conf

# Only for expired PGP keys -- DANGEROUS - always revert after updates.
# SigLevel = Required DatabaseOptional
SigLevel = Optional TrustAll

Recover from a Bad Upgrade with Encrypted Root Disk

Generally when Windows decides it's the boot manager and is wrong.

Boot from USB Boot Disk.

Mount LUKS Volume

ls -l /dev/{nvme,sd}*

# Mount LUKS encrypted partition.
crypt setup -v luksOpen /dev/{PARTITION} crypt_drive

# Mount and decrypt.
mount /dev/mapper/crypt_drive /mnt

# Switch to installed system root and update.
manjato-chroot /mnt
pacman-mirrors --fasttrack 5 && pacman -Syyu

# Update EFI boot manager.
efibootmgr -v
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
grub-mkconfig -o /boot/grub/grub.cfg
