 Posted: Sat Jul 31, 2004 8:28 pm Post subject: Inspiron 8200 Touchpad Driver - Advanced Features now work!! |
 |
|
I know lots of people like myself have been attempting to get the Dell I8200 touchpad edge scrolling to work correctly with the synaptics driver at http://w1.894.telia.com/~u89404340/touchpad/. Good news, Peter Österlund, the current maintainer, just emailed me to let me know that the driver should now work with the I8200 alps touchpad.
Just apply the alps.patch to your 2.6 kernel, build the new synaptics_drv.o and put it in the right path for your X modules. Follow the readme for a decent XF86Config and tweak it a bit to your liking.
It's still beta, but I have tested it and the driver does enable the special features in this touchpad. The tap/double-tap needs a bit of tweaking (let me know if you get it to work to your satisfaction), but this is a big improvement over previous tries! Kudos to the people who have worked so hard on this driver.
Anyway, here's the driver:

Okay, after applying another patch on top of the alps.patch, the tapping and double-tap work perfectly. I had to apply the patch by hand as I got 5 failed hunks while trying to patch it. Here's the patch (alps-hwtaps.patch):

Hi count_zero,
i've tried the alps patch again, and .. tada, some problems.
First of all, it seems to work, i can move the cursor, tapping and buttons are working. But, the keyboard does not work anymore.
After the first try i've got "out of sync" messages, to solve this i loaded the psmouse module with proto=bare. This prevent the above messages, but as i sayd, the keyboard isn't working anymore....
And another small thing ive wonder is, ive got no "alps" or "synaptics" in kernel output at startup. Is this normal?
Bye and thanks for the tip!

does this also work for other touchpads?
I mean the tapping, because this doesn't work on my notebook. |

What does (as root)
give you? Mine gives me:
| Code: | input: AlpsPS/2 ALPS TouchPad on isa0060/serio1
input: AT Translated Set 2 keyboard on isa0060/serio0
|
Did the new alps.patch and alps-hwtaps.patch apply cleanly? If so, the kernel should recognize your touchpad as an alps pad (if it truly is one). You're running an I8200?

@count_zero: Yes I'm running a I8200 (and it runs good) and the patch applied without error. I will try dmesg output again after work  but if i remember, there are no output like this .... more to come, over and out |

| Today i tried 0.13.5 and, juhuuu, it works! Ok, tapping is disabled by default, but edge scrolling works. Does anybody knows who to enable tapping? |

Sorry to be a bit of a newb here but how would I go about patching these two patches so they apply cleany. I'm currently running gentoo-dev-sources-2.6.7-r13 on a Inspiron 8200. I haven't tried these patches yet cuz I don't know how 
Thanks |

copy the patchfile alps.patch to your kernel source directory (/usr/src/linux-2.6.7-gentoo-r13) and do a
| Code: | | patch -p1 < alps.patch |
The -pX tells patch to cut the first part of the filenames listed in the patchfile from this path. I dont know from where the alps patch was created. Maybe you have to use -p0, just try, i've got no prompt or error during patching, if you got something, just try -p0...

| Ok i did this and it suceeded. I rebooted and then looked for the module or something to enable in the kernel menu to build the support but I couldn't find anything. I've applied the alps.patch. Should I apply the second patch that was posted up and above? second poster i believe |

The second patch need to be applied by hand... so i would leave it. Read the README file. There is written down what needs to be activated. There is no "Synaptics" or something in the kernel config, if i remember right you have to activate PS2 Mouse support, input core event support and maybe something else...
read the README! |

I have the first patch applied but it doesn't get read by xorg.conf. But when i run cat /dev/mice the mouse brings up random characters meaning its working.
What else could I try to get the touchpad working? |

The patch is for the kernel and xorg really shouldn't matter. Make sure that your synaptics_drv.o is in the right spot: /usr/X11R6/lib/modules/drivers and that this path is set in your xorg.conf file (it should be by default, but if not, just add the line
| Code: | | ModulePath "/usr/X11R6/lib/modules/drivers" |
You also have to load the module in your xorg.conf file, in your "Module" section:
Finally, make sure that your "InputDevice" mouse section contains something like I listed above.

Yeah I didn't need to patch all I had to do was emerge synaptics and then add that modulepath since it was commented and then insert the load in xorg.conf
And it works great =)
thank you so much |
