| 1 It is possible to use this driver with an ALPS Glidepoint device. If |
| 2 you use an older 2.6 linux kernel which has no ALPS input driver, you |
| 3 need to apply the ALPS kernel patch in the alps.patch file. See |
| 4 http://www.kernelnewbies.org/faq/ for information about how to apply |
| 5 kernel patches and compile kernels. |
| 6 |
| 7 Note! If you use kernel 2.6.11 or later, the alps patch is already |
| 8 included, so you don't have to patch your kernel. |
| 9 |
| 10 Since ALPS touchpads don't have the same resolution as Synaptics |
| 11 touchpads, you probably have to change some parameter values. Here is |
| 12 an example InputDevice section for the X configuration file. |

| 44 EndSection |
| 45 |
| 46 If you use a 2.4 linux kernel, you don't need to patch the kernel, but |
| 47 you should instead set "Protocol" like this: |
| 48 |
| 49 Option "Protocol" "alps" |
| 50 |
| 51 |
| 52 On some (all?) ALPS hardware, it is not possible to disable tapping |
| 53 unless you apply the patch below. However, some users have reported |
| 54 that this patch breaks tap-and-drag operations, which is why the patch |
| 55 is not included in the main alps.patch file. |
