I am facing some weird issues since a few days, all of which seem to be arising due to a single problem.
Once the boot menu pops up, the selection immediately jumps to the last entry (which in my case is 'Reboot into Firmware interface'). I need to go up and select a kernel explicitly, whatever be the default setting. During the boot, I see some
^[[6~ characters on the screen. Similarly, when I open some apps (say Geary), sometimes the list of messages automatically gets scrolled down to the last entry and tries to jump ahead of the last entry (beeping). If I press a button (any button), the movement stops. So basically I guess the system is registering down key-presses (or probably touchpad scroll) automatically during boot and in sometimes in some apps. During boot it is always reproducible, but not in the apps. Does the control character
^[[6~ point towards anything?
Any suggestions on diagnosing/resolving the problem?
p.s. I am using Solus Budgie (clr-boot-manager) on a Lenovo Z50-70 laptop.
