Mouse problem

[joc]

hi,

I'm trying to play nexuiz on a gentoo x86_64, and I have a strange mouse behaviour :
when using nexuiz-glx, the mouse "jump" when I move it so I can't aim the enemies. And with nexuiz-sdl, it slowly moves up, so I get stuck watching the ceiling.
in both case, I can't get fun with nexuiz

I try gl_finish 1, but it has not effect at all.

I have a microsoft intellimouse, and a Athlon X2 3800+

thanks in advance

Do you have a joystick attached? i have to use" joy_enable 0" in linux or i get messed up mouse input.

yes this was my joystick that get me stuck to the ceiling in the sdl version.

But I have still the "jump" problem in both sdl and glx.
it's something like a bad conversion between signed and unsigned integer, when I move the mouse, it jumps from one point to another sometime.
and I play with ut2004, quake4, doom3, and quake3 without problem.

the first time I start the game, my mouse works normally in the menu, ingame and when I come back to the menu, my mouse jumps, and it's not controllable.

I have the bug with both 2.2.2 and 2.2.3 version

Hmm thats interesting, i have no problems with both versions and i also can't think of a change in the input handling. (in case older versions DO run fine..)
I read in other games forums about problems with dga, or non-dga so maybe you can search google for more information about that.
You could also post your xorg.conf here so we can take a look at it.

I've never heard of such a problem before, and do not have a solution.

Entering/leaving the menu doesn't reset any mouse code.

You could try turning on vid_dga in the console, but that only works with nexuiz-glx, not nexuiz-sdl, and dga should not be necessary.

Hi,

I can confirm the problem.

It looks like this: I slowly move the mouse in any direction. Everything goes well until I hit a certain angle. Then, it abruptly jumps to somewhere else. Of course, it also happens when I move the mouse fast.

I thought at first this might be related to the wacom tablet I have connected, but other games (sauerbraten, warsow) don't show this problem.

I am also using x86_64 on a Core 2 Duo machine (Gentoo).

Wacom tablet eh? Lucky bastard.

I tried with vid_dga 1 in the console :
the mouse only move to my feet, even if I move my mouse up/down/left/right

here is my Xorg.conf for the mouse :
(yes I have a M$ intellimouse :p )

Section "InputDevice"

# Identifier and driver

Identifier "Mouse1"
Driver "mouse"

# The mouse protocol and device. The device is normally set to /dev/mouse,
# which is usually a symbolic link to the real device.

Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mouse0"
Option "ZAxisMapping" "6 7"
Option "Buttons" "7"

the module section :

The 5 buttons are working with Q3/Q4 and ut2k4

I will try without the Option "omit xfree86-dga" and with vid_dga.

I'm wondering if it's not a dual-core or a 64 bits issue, cause on my old PC it works like a charm with the same mouse and the same configuration.

[joc]

ok,

I have found that it is a dual core problem.
I have recompiled my kernel without SMP, and my mouse is working perfectly.

It's not an option for me to use only one core, because with gentoo, I need to compile package often, and it's really faster with two core.

I don't know if there is a command to tell to the kernel that a program must be run on only one CPU. (I do this on winXP with some games).
since nexuiz is mono-threaded, it probably won't affect performances.

thanks in advance

That's pretty strange, since Nexuiz works fine on my Core Duo notebook (32bit) and on Pentium 4 D dual core machines (64 bit)...
