I am trying to fix my mouse wheel... I found a post here that said I have to make a change to my xorg.conf file. Problem is... I can't find an xorg.conf file! I did a search and it came up with two files under /var/portage/... whatever. I don't think that those are the files I need to change.

Alternatively, I found a file /etc/X11/xorg.conf.example

I am assuming that the xorg.conf file should probably be under /etc/X11.......

I just installed Gentoo the other day and am running KDE. I did some looking in portage and found that I am running xorg-x11-6.8.2-r1

I need my mouse wheel... without it I will surely go mad! :-)

Appreciate the help.

Hi mate,
read this one http://www.gentoo.org/doc/en/xorg-config.xml to know how to configure X
basicly you do a command under root
Code:
 X -configure

then copy the new generated file xorg.conf.new to /etc/X11
Code:
 cp xorg.conf.new /etc/X11/xorg.conf

now you edit the xorg.conf from /etc/X11/xorg.conf

To use the wheel, add the following line inside the Section InputDevices (the mouse section) in your xorg.conf
Code:
Option "ZAxisMapping"  "4 5"


All the best!

So I ran the X -configure and then did the test as per the link you provided.

I get the following:

Quote:
(==) RADEON(0): Write-combining range (0xe8000000,0x8000000)

Please consult the The X.Org Foundation support
at http://wiki.X.Org
for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional information.


I checked my kernel config and I do have support for ATI Radeon adapters under 'Graphics Support'. I even recompiled the kernel to be sure.

What I don't get is if Xorg isn't configured then how am I running KDE right now?

if you know your hardware, you can use:
Code:
#/usr/X11R6/X11R6/bin/xorgconfig


X -configure never got it right for my system, and the above worked much better for me

It said it couldnt detect your mouse,
edit your xorg.conf file the mouse section(Section InputDevices)
Code:

change /dev/mouse to /dev/input/mice


see if that work. Btw..what type of mouse are you using? is that PS/2 or USB or serial?
Default kernel should detect fine with PS/2 or USB but serial mouse you need to compile kernel with extra modules.

Hope this help!!

d0nju4n: I tried using xorgconfig but I didn't feel very comfortable entering in values for my monitor. I used to have the refresh values written down somewhere but I couldn't find them. I'll see if I can dig up those values again tonight. I'm not at my home right now.

dellaxim: I will try your suggestion first as it is likely a little simpler to try out.

My mouse is a Logitech optical mouse (USB with a PS/2 adapter on it).

I am still concerned about the messages that I received concerning the video card. I checked and even recompiled my kernel to ensure that it had support for Radeon adapters. Yet it still said that it couldn't load the Radeon module. Is this one of those things that I shouldn't trouble myself over? Or is it a serious problem?

Oh well, I will go back it again tonight and keep you all posted. Thank you for the suggestions!

What is your monitor's brand and model number? These numbers shouldn't be too hard to track down on the net

My monitor is a Viewsonic A90f+ (19")

I think last time I had to look it up I found it on viewsonic's web site.. that was a long time ago. I am going to try dellaxim's suggestion right now.

I just want to say that you guys are awesome. The fix about using /dev/input/mice worked. Although I STILL find it odd that there was an issue with loading a kernel module for my Radeon adapter.

THANK YOU ALL!!!
