Strange mouse resolution ? 2 pixels by 2 pixels

Creak · 04-12-2004, 06:54 PM

Hi !

I don't understand why, and i don't know if there is some relation between the two events, but since i've installed the 2.6.3 kernel my mouse has lost some precision... i can only move the cursor by 2 pixels...

It's ok if you do just firefox, but i tried to play ut2004 and it's unplayable... so please help me... I need to play ut2k4

I can confirm this. My stock 2.6.3 kernel in Fedora Core 1 had a very fast mouse speed moving 2 pixels at a time.

Last night I compiled in a 2.6.4 kernel and the mouse is half speed and smooth 1 pixel movement again. I wondered why my mouse was half speed until I read this post. I didn't associate the two things.

So maybe it's a glitch in the 2.6.3 kernel. I am using a ps/2 intellimouse. Try compiling the newer kernel. I'd be interested to see if it fixes it for you.

i got also the 2.6.4 now and nothing changed... i've compiled the smaller kernel i could do... to be sure there was nothing that could interfere with my mouse driver.

Let make some comparisons

In my XF86Config-4 i got this for the mouse:

Code:

[...]

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "false"
        Option          "ZAxisMapping"          "4 5"
        Option          "SampleRate"            "150"
EndSection

Section "InputDevice"
        Identifier      "Generic Mouse"
        Driver          "mouse"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "false"
        Option          "ZAxisMapping"          "4 5"
EndSection

[...]

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
        InputDevice     "Generic Mouse"
EndSection

And i enabled this in my kernel config in relation with mice input (make menuconfig):
Device Drivers --> Input device supprt --> Enable /dev/psaux device by default
Device Drivers --> Input device supprt --> Mice
Device Drivers --> Input device supprt --> Mice --> PS/2 mouse

Please tell me your config so that maybe i could see what has generated this with my mouse

Thanks,

Can you tell me what's your mouse protocol ?

Because i've put Logitech instead of ImPS/2 and now it works find... the only problem is that my mouse can't handle fast moves... is there a way to increase PS/2 rate ??

Thanks !

I'll have to get back to you on this one tonight.

try :
xset m 1/2 1

you can also look at the resolution option in the mouse section in XF86Config-4

Regards

i already have the xset configuration, but i don't know how much i should put for the resolution... i tried 512 but nothing's changed... What are the bound values ?

Thks

Actually I have to take back what I said. The kernel compile was a co-incidence. Every once in a while the mouse is twice as fast for no reason. Next tie I start X it's ok.
