12.04, Keyboard Shortcuts do not work

Asked by Per Wahlström

Upgraded from 10.04 to 12.04. Keyboard shortcuts do not work. They show up in Keyboard Shortcuts though.

I have added two Custom Shortcuts:

  "Alt++" and "Alt+-".

which should run a script.

I have also modified keys for Sound and Media, volume down and up:

  "Pause" and "ScrollLock" respectively.

Also tried "Alt+Pause" instead of ScrollLock. ScrollLock will never work as a shortcut (worked fine on 10.04)

Strangely, the "Pause" shortcut always works (increase volume) - the others do not.

It does happen that they do work after a reboot (except for the ScrollLock one), and going to Keyboard Shortcuts Settings, but rarely.

If I go and change the shortcut key, then change it back, it works - until I reboot.

Maybe search bug reports and in case report a new one.
The issue with 'altxxx' may have some conflict with HUD which is assigned to 'alt L'.
Maybe disable HUD and test your custom shortcut again.
System settings - keyboard - shortcuts - launchers
Delete the shortcut <Alt L> or change it.
## If compizconfig-settings-manager is installed.
CCSM - workspace (category) - unity - behaviour - key to show the HUD
Click on <Alt> and deactivate.

Or login to guest account and test custom shortcuts there.

Update fixed the issue, except for the still unmappable scroll-lock key.

I was mistaken, the shortcuts just happened to work across several consecutive reboots, but it seems like random chance whether they do or not. When they don't, remapping them fixes it.

Possible scenario - bootup race condition between loading of shortcuts and something else that "unsets" them.

This is the additional issue that I faced with keyboard shortcuts but now you can see here https://sublimationprinterhub.com/ some detailed guidance about it and try to solve this issue.

Can you help with this problem?
