Lock screen; log back in; mouse is gone

mariojlhm · 2016-04-28 00:02:03

I have a feeling this is really straightforward, but my mouse disappears whenever I lock the screen and log back in. What should I do? Rebooting obviously fixes it...

Is it not functional? Like if you log in and it disappears can you still right click somewhere, blindly, on the desktop and get the drop down menu? Or is it like it's not even there, aka no click response?

mariojlhm, welcome to the forums!

are you sure that this is how it behaves?
if so, it could be a graphics issue.

but before jumping to conclusions, please do some more testing.
bunsenlabs can be used with the keyboard pretty much 100%; do you have all functionality there?
also, maybe it's enough to log out and back in (i believe the screenlocker does not actually log you out)?

Have you tried restarting the compositor:

pkill -USR1 compton

EDIT: wrong command, use this instead:

bl-cpompositor --restart

Make sure that the selected cursor theme matches the asterisked entry in the (interactive) output of:

sudo update-alternatives --config x-cursor-theme

Restarting the compositor works. This is weird! I guess I can just write a script to kill compton when I unlocked the screen?

Would this be a fault/bug of light-locker or something with compton?

Or a problem with the OP's system graphics? This sounds more likely because otherwise it would be a common problem I think.

Right...I'm curious to know rather the mouse buttons still work when it vanishes, or rather the the movement and clicking of the buttons doesn't work at all..

The mouse buttons still work, and windows still register mouse move events. I.e., google chrome tabs will light up when the 'cursor' moves over them. So, the cursor is there, I just can't see it.

I'm using an x220, so, nothing crazy. I noticed this broke after an update.

what's that, a mouse?
i don't think your problem is related to your actual mouse.

that would be more interesting. what did you update, what state is your system in, what sort of graphics card and driver are you using......

otoh, if it works with a workaround, i wouldn't worry about it.

By x220, I meant a Lenovo Thinkpad x220. It's a very well-supported machine. To be honest, I can't remember what broke it. It was something bunsen specific, i.e., probably light-locker. I'm using the trackpoint. The trackpad is disabled.

The mouse works. The mouse widget disappears after logging back in.

I'm not too worried, I'm mostly interested in helping the dev team by talking about the bug.

Hey mario for my own curiosity, could you post the results of:

xinput  --list

xinput --query-state  <x>

the x is the value of the ID that you got from your mouse in the --list command.

Though it seems like it's more of a video issue than anything actually wrong with the mouse config.

Sure:

mario@t420sputario:[~]$ xinput --list
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                       id=11    [slave  pointer  (2)]
⎣ Virtual core keyboard                       id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
    ↳ Power Button                                id=6    [slave  keyboard (3)]
    ↳ Video Bus                                   id=7    [slave  keyboard (3)]

    ↳ Integrated Camera                           id=9    [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                id=10    [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                      id=12    [slave  keyboard (3)]

...

mario@t420sputario:[~]$ xinput --query-state 4
2 classes :
ButtonClass
    button[1]=up
    button[2]=up
    button[3]=up
    button[4]=up
    button[5]=up
    button[6]=up
    button[7]=up
    button[8]=up
    button[9]=up
    button[10]=up
ValuatorClass Mode=Relative Proximity=In
    valuator[0]=683
    valuator[1]=384

These values do not change whether the mouse is visible or not visible.
