General Support - Annoying mouse and keyboard problem.

Titel: Annoying mouse and keyboard problem.

My mouse pointer sometimes moves to the bottom of the screen all by itself, at which point the keyboard gets disabled. Any attempt to move the pointer results in the same behaviour: the pointer sinks to the bottom again.
The inability to click anywhere before the pointer moves down again, makes it difficult to save and close applications. My only recourse is to restart my computer, which has led me to lose data Traurig

This happens at random every couple of weeks, google has been very unhelpful on this matter, any suggestions or ideas at all?

my first guess is a mechanical problem in the mouse, or electronic, try another mouse and see if the event duplicates. If you are using a usb mouse, use a standard, non-usb mouse if you have one.

Also, with optical mice, on a glossy surface they can act weird, but not like you are describing, but using a mousepad with optical mice is a good idea in general.

I'd go through these basics first. Hopefully you aren't using one of those widget filled mice that just lead to more problems than they solve, if you are, try a simple 3 button mouse and see if the problem duplicates.

I'm assuming this a desktop, not a laptop.

It's a laptop, not a desktop. My touchpad buttons are broken and I need to use a usb mouse since I don't have a ps/2 port or bluetooth. I've tried several mouse devices (the touchpad, 2 opticals and a balled one) and all have resulted in the behaviour mentioned above. I use my external mouse on a adequate mouse pad, but to no avail. This doesn't happen in windows, so it can't be hardware related.

I guess this is just one of those unsolved linux mysteries. :sigh:

have you disabled your touchpad in bios? That can help. It's probably some glitch in the xorg.conf file.

You might also try first disabling touchpad in bios, then booting into live easter cd, then using its x conf file and copying it over to the hard drive /etc/X11/xorg.conf, after backing up your original file of course.

I think easter live still will use the older x stuff, can't remember the name, x11r86 or something like that, that's the config file name too.

That sounds like a good idea, how do I disable my touchpad in bios?

On Laptops where you don't use stone age ps/2 and don't like the notepad to interfere with writing and your usb-mouse you may:

1) Disable the touchpad in your Bios (if you bios provides this switch and you never use it); or
2) Don't attach any mouse while installing Kanotix, use the touchpad for installation, and install ksynaptics after HD-install (disable the touchpad then in Kcontrol or via Kicker applet temporarily); or
3) If you have already installed, disable ALL pointing devices in your X11 configuration (/etc/X11/xorg.conf) and instead let hal/udev detect them:

Code:

Section "ServerLayout"

...

# PS/2 Mouse not detected

# Serial Mouse not detected

# InputDevice    "USB Mouse" "CorePointer"

# TouchPad not detected

EndSection

...

Section "Module"

...

# Load "synaptics"

EndSection

After that restart X and install ksynaptics as described above. This should do the trick here.

Greetings,
Chris

Re: Slam's post:

I completed step 3 since I had installed kanotix with my usb mouse and keyboard active. I restarted X. I then installed ksynaptics but was unable to change settings and received the following error message:

Zitat:

Shared Memory is not accessible.

Please add the option 'UseShm ''true''' into the touch pad section of /etc/X11/xorg.conf

So, I went ahead and added the following line to xorg.conf:

Code:

Section "InputDevice"

...

        Option          "UseShm"                "true"

and restarted X, but again the same error message cropped up. I even tried setting the option to "on", but again I got the same error.

I got nothing from google, any suggestions on the Shared Memory error?

shared memory means eiter graphiccard has got more memory after starting X or less. Can also be a Timingproblem wit throtteling up and down the cpu-freq, or defektiv memory module.
