The status of the check box used for activating and deactivating the

entry of accented letters depends on the respective language and does

not need to be changed. Click ‘Finish’ to apply the new settings to

your system.

Touchscreen Currently, XFree86 only supports Microtouch and Elo Touch-

Systems touchscreens. SaX2 can only autodetect the monitor, not the

toucher. The toucher is treated as an input device.

To conﬁgure the toucher, start SaX2 and select ‘Input devices’ ➝

‘Touchscreens’. Click ‘Add’ and add a touchscreen. Save the conﬁg-

uration by clicking ‘Finish’. You do not need to test the conﬁguration.

Touchscreens feature a variety of options and usually must be cali-

brated ﬁrst. Unfortunately, there is no general tool for this purpose in

Linux. The standard conﬁguration contains suitable default values for

the dimensions of the touchscreen. Normally, no additional conﬁgu-

ration is required.

Graphics Tablet Currently, XFree86 only supports a limited number of

graphics tablets. SaX2 enables the conﬁguration of graphics tablets

connected to the USB port or the serial port. From the conﬁguration

perspective, a graphics tablet is just an input device like a mouse.

Start SaX2 and select ‘Input devices’ ➝ ‘Graphics tablet’. Click ‘Add’,

select the vendor from the following dialog, and add a graphics

tablet from the selection list. Mark the check boxes to the right if you

have connected a pen or eraser. If your tablet is connected to the se-

rial port, verify the port. /dev/ttyS0 refers to the ﬁrst serial port.

/dev/ttyS1 refers to the second. Additional ports use similar nota-

tion. Save the conﬁguration by clicking ‘Finish’.

AccessX

If you do not use a mouse on your computer, start SaX2 and activate Ac-

cessX to be able to control the mouse pointer with the keys on the numeric

keypad. (See Table 2.1 on the facing page).
