Talk:How to configure the TrackPoint
On Fedora 5, with kernels 2.6.15 and forward, the path does not include serio2; it stops at serio0.
2005-11-07 OpenSuSE 10.0 has a kernel based on 2.6.13 (probably heavily patched), but the directory /sys/devices/platform/i8042/serio0/serio2 does not exist. instead, it looks like this:
hoppetosse:/sys/devices/platform/i8042/serio0 # ls -l total 0 -rw-r--r-- 1 root root 4096 Nov 7 18:38 bind_mode lrwxrwxrwx 1 root root 0 Nov 7 18:38 bus -> ../../../../bus/serio -r--r--r-- 1 root root 4096 Nov 7 18:38 description lrwxrwxrwx 1 root root 0 Nov 7 18:38 driver -> ../../../../bus/serio/drivers/psmouse --w------- 1 root root 4096 Nov 7 18:38 drvctl drwxr-xr-x 2 root root 0 Nov 7 18:38 id -r--r--r-- 1 root root 4096 Nov 7 18:38 modalias drwxr-xr-x 2 root root 0 Nov 7 18:38 power -rw-r--r-- 1 root root 4096 Nov 7 18:38 protocol -rw-r--r-- 1 root root 4096 Nov 7 18:38 rate -rw-r--r-- 1 root root 4096 Nov 7 18:38 resetafter -rw-r--r-- 1 root root 4096 Nov 7 18:38 resolution
"description" says it's an "i8042 Aux Port". The page Patch to enable advanced trackpoint control seems to imply that a kernel patch is needed in order to get those features... this needs clarification. hmm. where can i find out whether "drvctrl" is what i'm looking for and what options it takes? guess it's back to RTFS...
2005-10-06 It seems that new version of the patch ( 2.6.12 at least ), the press to select entry in /sys is named "press_to_select" and not "ptson". I changed the page accordingly so that it complies with the Patch to enable advanced trackpoint configuration page. If you use an older version try :
Press to Select
Press to Select allows you to tap the control stick which will simulate a left click. You can enable this feature by typing the following in to a terminal (you may need to be root):
# echo 1 > /sys/devices/platform/i8042/serio0/ptson
Press to Select should now be enabled. You can disable it in a similar manner:
# echo 0 > /sys/devices/platform/i8042/serio0/ptson
