Subject: [PATCH] xfree86: if AllowEmptyInput is true, enable RAW mode on the console.
|
|
|
|
Usually, the console is set to RAW in the kbd driver. If we hotplug all input
|
|
devices (i.e. the evdev driver for keyboards) and the console is left as-is.
|
|
As a result, the evdev driver must put an EVIOCGRAB on the device to avoid
|
|
characters leaking onto the console. This again breaks many things, amongst
|
|
them lirc, in-kernel mouse button emulation and HAL.
|
|
|
|
This patch sets the console to RAW if AllowEmptyInput is on.
|
|
|
|
Use-cases:
|
|
1. AEI is off
|
|
1.1. Only kbd driver is used - behaviour as-is.
|
|
1.2. kbd and evdev driver is used: if evdev does not grab the device,
|
|
duplicate events are generated.
|
|
2. AEI is on
|
|
2.1. Only evdev driver is used - behaviour as-is, but evdev does not need
|
|
to grab the device anymore.
|
|
2.2. evdev and kbd are used: duplicate key events are generated if evdev
|
|
does not grab the device.
|
|
|
|
1.2 is a marginal use-case that can be fixed by adding a "grab" option to the
|
|
evdev driver (update of xorg.conf is needed).
|
|
|
|
2.2 is an issue. If we have no ServerLayout section, AEI is on, but devices
|
|
specified in the xorg.conf are still added [1], resulting in duplicate events.
|
|
This is a common configuration and needs sorting out.
