## Environment variables
|
||
|
||
Unless specified otherwise, a variable is enabled if and only if it's set to `1`
|
||
|
||
### DRM
|
||
|
||
### DRM Devices and Settings
|
||
|
||
`AQ_DRM_DEVICES` -> This option allows you to set a specific list of DRM devices (GPUs) for the system to use.
|
||
The list is separated by colons (:), and the first device listed will be the primary GPU.
|
||
For example: `/dev/dri/card1:/dev/dri/card0`.
|
||
This means the system will primarily use `card1` and then fall back to `card0` if needed.
|
||
|
||
`AQ_NO_ATOMIC` -> Disables atomic mode setting for the DRM.
|
||
Atomic mode setting is a feature that makes screen updates more reliable by grouping changes together.
|
||
Setting AQ_NO_ATOMIC to 1 can be useful on hardware or drivers that don’t fully support atomic mode setting,
|
||
as it can prevent crashes or freezes caused by incomplete or incorrect atomic updates.
|
||
|
||
`AQ_MGPU_NO_EXPLICIT` -> Disables explicit synchronization between buffers when using multiple GPUs (multi-GPU setups).
|
||
Without explicit syncing, the system handles buffer transfers between GPUs more automatically,
|
||
which can improve performance in some cases but might introduce errors in more complex setups.
|
||
|
||
`AQ_NO_MODIFIERS` -> Disables DRM modifiers for buffers.
|
||
This can also resolve issues where a monitor fails to turn on or is not detected properly.
|
||
DRM modifiers define how pixel data is stored in memory (e.g., in optimized formats).
|
||
Setting `AQ_NO_MODIFIERS` to `1` ensures simpler buffer handling,
|
||
which might be necessary on hardware that doesn’t support advanced memory layouts,
|
||
especially for high resolutions like 4K.
|
||
|
||
### Debugging
|
||
|
||
`AQ_TRACE` -> Enables trace (very verbose) logging
