"Ctrl+Shift" and "Ctrl+Alt" key combinations not working

Post by cwatson » 2020/02/14 17:57:34

Hi, I'm not sure if this is the best sub-forum for the topic but since I booted up I can't make key combinations of "Ctrl+Alt+X" or "Ctrl+Shift+X" (where "X" is any other key). This includes some keyboard shortcuts I use (in Mate) and using e.g. "Ctrl+Shift+Tab" in Firefox.
I had previously done a small update but don't know what could have caused this. Here is some info:

Code: Select all

Linux localhost.localdomain 3.10.0-1062.9.1.el7.x86_64 #1 SMP Fri Dec 6 15:49:49 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Please note that I had updated to kernel 3.10.0-1062.12.1, but booted into the lower version in the case that the kernel update caused the issue.
The desktop environment I use is mate 1.16.

Here is a pastebin link with the yum packages updated in the past day or so: https://pastebin.com/VthETh8y
I am happy to provide any more information as required.
