In > another Linux? In Windows? Any BIOS option to enable it? When I first installed, the mouse was on the ps/2 port. The configuration that was supplied by the installer was Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device""/dev/input/mice" Option "Protocol" "ImPS/2" Option "Emulate3Buttons" "true" EndSection The mouse did not work. I moved the mouse from the ps/2 port to the USB port and it worked fine. Then I tried changing /dev/input/mice to /dev/psaux. The mouse WORKED FINE with this setup. (It worked just as well as it worked on the USB or as it now works with evdev on the USB---everything worked but the tilting of the tilt wheel.) This seems puzzling in light of the recent behavior with /dev/psaux. Is it possible that some action (e.g. reboot) is necessary to cause the kernel to realize there is a mouse on the ps/2 port? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

In > another Linux? In Windows? Any BIOS option to enable it? I rebooted with the mouse in the ps/2 port and tried the experiment again. When I do 'cat /dev/psaux' or 'cat /dev/input/mice' and move the mouse I see characters on the terminal in both cases. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

And > check whether PS/2 works in other Linux/OS if you can. This is a brand new machine that has only the one OS installed. I tried booting Knoppix and it wouldn't boot. So I don't think we're going to see other OS results. After observing that /dev/input/mice was responding to the mouse I changed the X config to Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device""/dev/input/mice" Option "Protocol" "ImPS/2" Option "Buttons" "7" Option "Resolution""1000" EndSection and restarted X and at that point it started working. This is the first time I've seen the ps/2 mouse work with /dev/input/mice. This is basically the same X configuration that wasn't working when the system first installed. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

I have never observed /dev/input/mice to work when the mouse was plugged into the PS/2 port. At the moment I am using evdev and have the mouse plugged into the USB and the mouse works. If I switch it to the PS/2 it doesn't work. After switching the mouse to the PS/2 I tried "cat /dev/input/mice" and saw nothing. I also tried "cat /dev/psaux" and also saw nothing. (Is some action required for the PS/2 port to realize it's got a mouse connected?) Just as a confirmation I put the mouse back in the USB and did "cat /dev/input/mice" and when I moved the mouse I got characters.

The information I found floating around indicated that with recent versions of evdev, the simple configuration shown below is supposed to work. Additional options are not supposed to be necessary. I did also note that the evdev instructions make it sound like evdev should work fine with a ps/2 connected mouse, which would seem to implicate the kernel as you suggested above. (I don't think this is an exotic mouse. Why would the kernel have trouble with it?) Note that the mouse works with evdev as long as the mouse is in the USB. It's just the tilt wheel that doesn't work. (I checked with xev and it shows no event for the tilt wheel.) The mouse does not work with evdev if I plug it into the ps/2 port. > > > (II) evdev brain: Rescanning devices (1). > > (EE) PreInit returned NULL for "Configured Mouse" > > (WW) : No Device specified, looking for one... > > (II) : Setting Device option to "/dev/input/mice" > > (--) : Device: "/dev/input/mice" > > (==) : Protocol: "Auto" > > (**) Option "CorePointer" > > (**) : Core Pointer > > (==) : Emulate3Buttons, Emulate3Timeout: 50 > > (**) : ZAxisMapping: buttons 4 and 5 > > (**) : Buttons: 9 > > (**) : Sensitivity: 1 > > > > Looks like evdev is using /dev/input/mice here. > > > Module Size Used by > > psmouse34952 0 > > > > Looks good. > > Brice > -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
