+It is possible to use this driver with an ALPS Glidepoint device. If |
+you use an older 2.6 linux kernel which has no ALPS input driver, you |
+need to apply the ALPS kernel patch in the alps.patch file. See |
+http://www.kernelnewbies.org/faq/ for information about how to apply |
+kernel patches and compile kernels. |
+ |
+Note! If you use kernel 2.6.11 or later, the alps patch is already |
+included, so you don't have to patch your kernel. |
+ |
+Since ALPS touchpads don't have the same resolution as Synaptics |
+touchpads, you probably have to change some parameter values. Here is |
+an example InputDevice section for the X configuration file. |
+ |
+Section "InputDevice" |
+ Driver "synaptics" |
+ Identifier "Mouse[1]" |
+ Option "Device" "/dev/psaux" |
+ Option "Protocol" "auto-dev" |
+# enable SHMConfig if you want to enable synclient |
+# NB: enabling SHMConfig is insecure, since any user can invoke it |
+# Option "SHMConfig" "on" |
+ Option "LeftEdge" "120" |
+ Option "RightEdge" "830" |
+ Option "TopEdge" "120" |
+ Option "BottomEdge" "650" |

+ Option "FingerHigh" "15" |
+ Option "MaxTapTime" "180" |
+ Option "MaxTapMove" "110" |
+ Option "EmulateMidButtonTime" "75" |
+ Option "VertScrollDelta" "20" |
+ Option "HorizScrollDelta" "20" |
+ Option "CornerCoasting" "1" |
+ Option "CoastingSpeed" "3" |
+ Option "MinSpeed" "0.3" |
+ Option "MaxSpeed" "0.75" |
+ Option "AccelFactor" "0.015" |
+ Option "EdgeMotionMinSpeed" "200" |
+ Option "EdgeMotionMaxSpeed" "200" |
+ Option "UpDownScrolling" "1" |
+ Option "CircularScrolling" "1" |
+ Option "CircScrollDelta" "0.1" |
+ Option "CircScrollTrigger" "2" |
+EndSection |

+If you use a 2.4 linux kernel, you don't need to patch the kernel, but |
+you should instead set "Protocol" like this: |
+ |
+ Option "Protocol" "alps" |
+ |
+ |
+On some (all?) ALPS hardware, it is not possible to disable tapping |
+unless you apply the patch below. However, some users have reported |
+that this patch breaks tap-and-drag operations, which is why the patch |
+is not included in the main alps.patch file. |
