Random unwanted keyboard key repeats

kr flag

I am having a serious issue with the keyboard on my SAGER NP7859PQ-S (CLEVO NH58HPQ) laptop. I am running Ubuntu 20.04.3 LTS.

Randomly, when I am typing or moving the cursor with the arrow keys, a key will start repeating. It is not the key that I last pressed. Pressing another key usually stops the unwanted repeating. But, sometimes, the key that is repeating is the CTRL key, which makes it almost impossible to continue. When this happens, I need to use the mouse to log off. Logging back in “fixes” that occurrence, but it will happen again. This000000000000000000000000000000000 is NOT an issue of the keys physically sticking.

Here is an example of the unwanted key repeat issue using the standard Text Editor. At the end of this sentence I will start using the arrow keys to move around the file.

The row of 0s above occurred when I pressed and held the Up Arrow key at the end of the previous sentence.

This entry was logged in /var/log/syslog:

Oct 16 14:30:49 SAGER kernel: [  628.638010] atkbd serio0: Unknown key pressed (translated set 2, code 0x65 on isa0060/serio0).
Oct 16 14:30:49 SAGER kernel: [  628.638023] atkbd serio0: Use 'setkeycodes 65 <keycode>' to make it known.

Reinstalling xserver-xorg-input-all does NOT fix the problem.

Updating grub to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.direct i8042.dumbkbd"

helped some, but did not fix the issue.

Any suggestions on how to further track this down?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
