The problem
After a recent automatic update I noticed the Ctrl + Alt + T shortcut was no longer working (gives the special character Ŧ instead). Neither was Alt + Tab when attempting to toggle between applications.
What I believe to be the issue
In the preview image of my keyboard layout I saw that ISO Level3 Shift was showing up where my Alt keys should have been (either side of Space). I am pretty sure this has changed since the update and is causing me the issue.
What I have research/tried
Unchecking ¨Any Alt¨ under ¨Key to choose the 3rd level¨ option in the advanced tab of the keyboard settings:
- Changed the preview to show Meta/Alt left and right keys in right place but still didn´t fix the problem
- Also introduced a few other problems
I looked into changing xmodmap settings but found out that this had been replaced by xkb in Ubuntu. Following some more research I tried opening /usr/share/X11/xkb/symbols/gb and tried commenting out the include "level3(ralt_switch)" text in the corresponding sections for my layout type (Macintosh variants). This did work for re-enabling the Alt key functionality but my d key stopped working.....(but still worked on chrome if not in a us english layout).
I´ve now returned those files to the way they were and re-selected "Key to choose the 3rd level" option in the advanced tab of the keyboard settings. My Alt key currently is working as suspected but my d key doesn't work along with other issues.
Running setxkbmap -layout gb gets the d key working again but breaks the Alt key and swaps my " and @ second options. I guess this is because it's changed basic to default english layout and I intend on using the Macintosh option.
If anyone could help me with this issue I'd be very grateful as it's currently driving me insane.
