Mouse not recognized in KDE

Message

I just installed gentoo and emerged KDE. When I go into KDE though the mouse doesn't work. Its odd because it worked when I booted from the livecd. When I do cat /proc/bus/input/devices on the livecd the mouse seems to be clearly defined, but when I boot normally an try the same command it doesn't appear. Also I did add support fot USB HID(Human Interface Devices) in my kernel.

I've trieed searching and I've found plenty of stuff on getting multiple buttons and so forth working, but my cursor doesnt even move. I have a Logitech mx700. I'm still pretty new at this so if someone could explain how to fix this I'd appreciate it.

Also, where exactly is the config file for kde stored? I see an example stored in /etc/X11/xorg.conf.example. I tried just coping it and leaving the .example off and kde crashes, so there must be a working config file its using some where. I've heard that you need to edit these as part of getting the mouse to work.

the xorg.conf file is a config for x, not for kde. You need to make sure the mouse section of the file is set up to work with your mouse. There are lots of examples for that particular one, so you shouldn't have a problem fixing your xorg.conf. (While you're at it, you might want to set up your video too

)

As for kde config files, you can look in ~/.kde for user specific kde settings.

Moved from Kernel & Hardware to Desktop Environments.

I've maganed to hack together a semi-working xorg.conf file. When trying to use the "default" setting for the mouse given here

Code: Select all

...
Section "InputDevice"
    Identifier  "Mouse0"
    Driver      "mouse"
    Option      "Protocol"     "ImPS/2"
    Option      "Device"       "/dev/mouse"
    Option      "Protocol" "auto"
    Option      "Device" "/dev/input/mice"
    Option      "ZAxisMapping" "4 5"
EndSection
...

i get the following errors.

Code: Select all

(EE) xf86OpenSerial: Cannot open device /dev/mouse
               No such file or directory.
(EE) Mouse1: cannot open input device
(EE) PreInit failed for input device "Mouse1"
No core Pointer

Any ideas? As I said, the mouse worked fine under the livecd so there has to be something else going on here.

ok removing /dev/mouse, I guess its just in /dev/input/mice, seems to clear it up and KDE loads. But I still can't move the cursor, so still have the same problem.

There are several possible areas in /dev your mouse could be... have a wee seach though the forums to find the possibilities... to check if its the right one...

cat "insert possible location here" and then move the mouse... if u get a stream of weird characters... thats the correct one

From a console type

Code: Select all

cat /dev/input/mice

and move the mouse and see if there is some garbage characters displayed on the screen.

i have tried all the locations possible. /dev/input/mouse0 though 3 give the following

Code: Select all

cat: /dev/input/mouse0: No such device

cat /dev/input/mice does not give an error, but does not output anything either.

what type of mouse do you have?

if usb, did you compile support into the kernel?

its a usb logitech mx700. What I think may be the problem is I didnt comiple the usb support as modules, so I'm trying that now.

EUREKA!!!!

That did it, I recompiled the usb support as modules then made them autoload by adding them to /etc/modules.autoload.d/kernel-2.6. Now cat /dev/input/mice gives me all kinds of beautiful gibberish.
