switchable
A command-line tool to enable switchable graphics for certain commands.
You won't need to type DRI_PRIME=1 steam
again.
Usage
Write the following to the configuration file ~/.config/switchable/config.toml
.
"match": [ "steam" ]
And then just run a command that matches.
steam
And it will automatically use your discrete GPU. (Read below for requirements)
Requirements
- bash
- bash-preexec
Installation
cargo install switchable
- Add
eval "$( switchable init )"
to your.bashrc
Configuration
We first look at ~/.config/switchable/config.toml
, and if that doesn't exist,
we try ~/.switchable/config.toml
.
The configuration is a TOML file with the following keys:
# Default value for DRI_PRIME
driver = 1
# Path to bash-preexec if it's not in its default location
preexec = "/home/user/.bash-preexec.sh"
# Regexes to match commands against
match = [
"steam",
"echo",
]
# Commands to alias
alias = [
"glxgears",
]
Caveats
switchable run
doesn't work with aliases such as ll
.
Doesn't work with pipes or &&-chained commands unless you use preexec, in which case there may be false positives.
