I have a CM devastator keyboard with back lighting. This keyboard uses the scroll lock key to turn the light on and off. On my system running Ubuntu under other desktop environments like Mate or KDE I can turn the back light on using xset led 3 and I usually have it scripted to turn on after I log in. Under Trinity doing xset led 3 causes the keyboard to flash really quickly once and then the light goes off. Is there something holding the keyboard under Trinity? Is there a way to use the back light?
I have suspicion that this is caused by tdekbdledsync. Try killing it. This daemon is extremely weird solution to a very uncommon problem and for whatever reason AFAIK there is no way to disable it "correctly". I have
sudo killall tdekbdledsync
in autostart to deal with this bullshit
