Linux Laptop Notes

Display

Two scripts for single and dual monitor display (if can’t get auto-HDMI detection working): Single:

1
2

#!/bin/sh
xrandr --output Virtual2 --off --output Virtual1 --primary --mode 1280x800 --rotate normal

Dual:

1
2

#!/bin/sh
xrandr --output Virtual2 --mode 1280x800 --primary --rotate normal --output Virtual1 --primary --mode 1280x800 --right-of Virtual2

Can then set up key bindings Edit .xbindkeysrc

1
2
3

# Single screen
"~/single.sh"
	Alt + F7

1

3

# Double screen
"~/dual.sh"
	Alt + F8

Edit conky.conf:

2

Alt + F7${alignr}Single Monitor
Alt + F8${alignr}Dual Monitor

Terminals

Tilix looks to be a really nice terminal, with the potential of auto profile switching when moving between hosts (help distinguish servers), but I haven’t managed to consistently get it working yet. Prefer the master approach here rather than deploying a script to clients:

Mail ‘client’

Use chromium app to have separate window for email. In BunsenLabs this then gains the icon from the favicon, so a nice appropriate and separate icon on tint2 bar

Singularity

Getting “ERROR : Failed to create container process: Operation not permitted” build” error when attempting to build: Quick fix

1

echo 1 > /proc/sys/kernel/unprivileged_userns_clone

Permanent fix via sysctl

1

echo 'kernel.unprivileged_userns_clone=1' | sudo tee /etc/sysctl.d/00-local-userns.conf

Miscellaneous

• To stop right click close in tint2, edit config and set “mouse_right = none”
