Alps touchpad configuration died on me

volvogga · 05-04-2007, 11:05 PM

I really killed something on my Inspiron 6000D. I did a whole big batch of updates today. Everything seemed to go fine... a few reboots later I was onto the ATI card driver update (a new Kernel, a new driver), so I went and installed that (ATI official one using the --buildpkg Fedora/FC6 method... yes, I just read the sticky, but does that still apply?).
Coming back out of the restart, my Alps pad is shot to hell. Middle click is emulated by both clicking buttons, but that's it. I lost my scroll, I lost my side scroll (although... not sure if that ever worked), and my corner middle click.

So yay!
I go looking for answers and I find Ksynaptics suggested. Sounds good, so try that... no go. I get "Shared Memory not accessible. Please enable 'UseShm "true"' in xorg.conf." Then it loads and looking at the screen, I don't think the driver is loaded (which makes sense... go figure!).

Soooo... ATI messed up my xorg.conf? Sounds possible. Take a look at that... I get the following in /etc/x11/.

Code:

~
-rw-r--r-- 1 root root 4470 May  4 16:50 xorg.conf.backup
-rw-r--r-- 1 root root 3363 Aug 25  2006 xorg.conf.backup-ati-fglrx
-rw-rw-r-- 1 root root 3951 Mar 12 19:09 xorg.conf.original-0
-rw-rw-r-- 1 root root 4527 May  4 21:02 xorg.conf.original-1
-rw-r--r-- 1 root root  492 Nov 11 10:57 Xresources

Well obviously there are backups... but then which one is being used right now?
I'm pretty lost. So does anyone happen to know what file to edit, and what to edit within (I seem to get a different suggestion on how to edit everywhere I go)?

Thanks a lot... sorry about being long-winded.

Obviously, the one that's "being used right now" is /etc/X11/xorg.conf.

I suspect you intended to ask "Which is the backup from which to pull the mouse pad info?"

If that was your question, you have two backups from yesterday. One of them is xorg.conf.backup made at 16:50, and the other one, xorg.conf.original-1 was created 4 hours later, at 21:02.

From your description of what you tried, I suspect that the working ALPS setup will be found in the earlier backup: xorg.conf.backup. Do a diff on the two files to see what's been changed. In fact, a diff between the 16:50 backup (e.g., before you did anything) and the 21:02 backup will show you what was changed by the updates you installed during the four hour period, and a diff between the 21:05 backup and your current xorg.conf will show you what was changed when you did the ksynaptics installation.

ok, thank you for the reply... fair enough. But... yeah, funny thing, I ment what I said. ^^;

xorg.conf is just kinda gone.

So do I just make a new one with

Code:

cp xorg.conf.backup xorg.conf

?
After I check it for the correct configuration, or course.

Thanks again.

PTrenholme · 05-06-2007, 08:18 AM

Weird.

Yes, do that.

So, do you have any X with a missing xorg.conf file?

volvogga · 05-06-2007, 02:57 PM

Yes... yes I have X... and I don't know why. *sobs in the corner*

In anycase, that fixed it to the point where my mouse has returned to it's origonal glory. Thanks very much.

What's weird is I'm still catching hell from ksynaptics. I'd really like to use this utility, so if you wouldn't mind helping me further, I'd appreciate it. I added that "UseShm" "true" to xorg.conf (after I found everything was good again) and I still get the error message that it's not using shared memory.

Here's xorg.conf. I thought I did it right, but perhaps there's a mistake in it.

the Load "Synaptics" and "UseShm" is there... do I need something that specificly says 'Alps' in there maybe?

EDIT:
Nevermind, I got it. Had to set an option of "SHMconfig" "1" in xorg.conf and it ran fine. Thanks again for all the help.

I think you may be missing a piece, Here's what the Synaptics section looks like on my laptop:

Code:

Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "yes"
        Option      "SHMConfig" "true"
        Option      "UseShm" "true"
EndSection

Note the option preceeding the UseShm one.
