I have Red Hat Linux 8 with the standard grapgical interface. The mose works fine but it doesn't have the midle button working correctly. In windows I could scroll up/down with it but in Linux it can only cut/past. Is there any solution tro get this midle "button" to scroll up/down again?

That's a good question, However, it doesn't work on linux. Well for me it didnt when i had mandrake, i'm not really sure if it does. Sorry i'm not of help.

found this somewhere just yesterday (cant remember, maybe a howto?) edit the /etc/X11/XF86Config (Backup it up of course...) scoll down till you find the mouse section and add Option "Buttons" "5" Option "ZAxisMapping" "4 5" so mine looks like this... *snip* Identifier "Mouse1" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/psaux"# When using XQUEUE, comment out the above two lines, and uncomment Option "Buttons" "5" Option "ZAxisMapping" "4 5" EndSection

open a shell you will have to be root to do this type setup on the menu choose mouse configuration then select Microsoft IntelliMouse (PS/2) if you ps/2 mouse this will select a new driver for you mouse then select ok you may have restart kde or gnome this worked for using a hp mouse with scroll

Check your /etc/X11/XF86Config(-4) file, make sure that: 1) YOU HAVE BACKED IT UP FIRST BEFORE EDITING IT! 2) The protocol is IMPS/2 (not just PS/2) 3) The ZAxisMapping 4 5 line is in there (as stated above) 4) Disable Emulate3Buttons (comment it out or set it to "no" or "false") Restart your X server and hope for the best!=o)

Thanks for the advice. I just tried Trevor's advice(the most esiest) and it worked for me. Thanks a lot!!!! I have an inland optical mouse . PS/2 I think, it not USB.
