linuxmint 19.1: power button inserts letters (works fine on linuxmint 18.3)












0















I recently did a clean install of LinuxMint 19.1 (MATE edition) on my laptop. Since then, pressing the power button inserts a long row of



dddddddddddddddddddddddddddddddddddd



until I press it again, which leads the insertion of d to stop. Pressing it aditional times mutes and unmutes the volume.



Assigning any actions to the powerbutton via the mate control center (eg, suspend or shutdown) has no effect.



If I boot my laptop from a LinuxMint 18.3 live system using a USB flash drive (the OS I was using before), the power button works as expected.



How can I fix this?



This is on a Lenovo Thinkpad X230 that, as mentioned above, works fine with LinuxMint 18.3.
