Is it a wired keyboard, or a wireless one with a USB RF receiver? It's a wired keyboard. Thanks, bit weird. Can you paste or attach the output of `sudo libinput list-devices`? Created attachment 184269 [details]

Well, that's the problem: > Device: SEM USB Keyboard Consumer Control > [...] > Capabilities: keyboard pointer The keyboard is telling us it's also a mouse! The presence of the words "Consumer Control" in the name originally made me suspect it was an RF receiver for a mouse/keyboard pair, because you often see those words used for that kind of hardware, and those also show up as both a keyboard and a mouse. I suspect what's going on is that the vendor cheaped out and used the same hardware only with a wired form factor, so it still tells the system it's a receiver for a mouse/keyboard pair even though it isn't. Ultimately this is yet another case of the generic issue Bug 465957, which tracks us figuring out a way to filter out these kinds of lying devices. *** This bug has been marked as a duplicate of bug 465957 *** |
