My keyboard repeat & delay settings are occasionaly reverted to slow (apparently default) values under Xorg in Ubuntu 18.04.
In this situation, the actual values (as obtained by
xset q) are
auto repeat delay: 500 repeat rate: 30
gsettings get org.gnome.desktop.peripherals.keyboard delay returns:
If I afterwards run
gsettings set org.gnome.desktop.peripherals.keyboard delay 250, the keyboard delay / repeat settings are correctly set (
xset q then returns
auto repeat delay: 250).
There seem to be several triggers for the behavior, one reproducibly being a suspend & wakeup cycle; I wasn't able to reproduce others yet.
My system is a rather freshly installed Ubuntu 18.04 on an A10-5800K with an A78M-E35 board in BIOS (non EFI) mode.
Any hints would be highly appreciated.
