Mouse Problem
 

When I load KDE my mouse will only move up and down, and it's no matter which direction I move my mouse. It makes random clicks and just acts plain weird. Any idea's?

Do you have a USB or PS/2 mouse? If you have a USB mouse, you might want to use the PS/2 adapter, if one came with it; I noticed that on Linux generally that produces fewer problems.

Also, check the mouse settings in "/etc/X11/xorg.conf".

I had similar problems when installing Slackware 10.2 for the first time. After installing it again, I discovered what the problem was: You (apparently) have to select the right mouse driver for gdm. If you choose "Regular PS/2 mouse" or something, it's apparently the best choice.

For X Windows (and KDE), in /etc/X11/xorg.conf", try selecting the ImPS/2 protocol:

I tried using one of the adapters and it says that it can't find any device.

and I have all my settings the same as that, and it still doesn't work.. like, the mouse moves.. but it does all kinds of whacky stuff:

moving only up and down.
If I click on any of the buttons and hold and move the mouse, it will move only to the right, but it'll move diaganally (spl)
also when I click on the buttons the cursor will move slightly to the right.. a couple of pixels.
it also randomly middle clicks..even if I don't move it or anything



I tried using the protocol microsoft, and it was completly eratic.. It moved but in every direction no pattern or anything.


It's a wireless microsoft mouse, USB

I also had this issue, and setting the right protocol (imps/2) was not the solution. I solved this problem on my slack 10.2 install by uncommenting /sbin/modprobe/hid in /etc/rc.d/rc.modules. it's the first item under the heading "### USB Device Support"

if that's not enough, try uncommenting the next line too (usbmouse)

once I compiled a new kernel though, this problem was gone and I re-commented the hid line in rc.modules.

Will this allow it to work as a USB mouse or will I have to use it as PS/2?

my mouse is USB, M$ "comfort optical 3000", should be no need to use a ps/2 converter.

Option "CorePointer"
 

I removed the line
Options "AlwaysCore" and
added the line
Option "CorePointer"
to Synaptics Touchpad and USB Mouse Sections, and it worked greatly.
I hope it will be useful...

What does "X -configure" say?
 

For ages, I've used the following command as root, especially in the newer 2.6.24+ kernels,
and then examined xorg.conf.new in the root directory as a skeleton to tweak. I usually end up with
On some laptops, to allow use of a hotplugged USB mouse in addition to the built in touchpad or button I add a second "Mouse1" section with
Since 12.0 (either Slackware of SLAMD64) I haven't had issues hot plugging USB mice. It is well worth the effort to see what X will autodetect before just throwing together whatever configuration file you think should work.
