I installed Elementary os 0.4.1 loki on my Sony SVE1513W1RB. First I encountered a problem when the system wakes up from suspend keyboard and touch pad won't work. Fixed this problem by adding i8042.direct i8042.dumbkbd into file /etc/default/grub into parametr GRUB_CMDLINE_LINUX_DEFAULT. Now when system resumes after suspend all keyboard indicators (caps lock, scroll lock, num lock) are always lighting up and are uncontrollable. Can I fix it?

Here you can see why the indicators don't work. It's caused by i8042.dumbkbd. If you delete that part the issue will disappear.

Also, checking this question I've found that using atkbd.reset instead of i8042.direct i8042.dumbkbd will make the keyboard and touchpad work without having the issues that you comment.

So, just change that line and don't forget to sudo update-grub and reboot.

  • Can you try with atkbd.reset?
