I have just recently switched from Windows 7 to Ubuntu Mate and the current version I have is Ubuntu 22.04.1 LTS "jammy". My laptop goes back to 2016 and is a Toshiba. I've completely erased the Windows 7 and installed the Ubuntu using a USB key. Everything was working properly during the installer (keyboard and mouse) but after that, the keyboard and mouse stopped working. I have to stay that the CAP. key's button stays "on" and the combination of the Fn key and brightness keys works but doesn't work with other keys (like volume).
Looking up this issue on Google I've found that some suggested:
sudo apt-get install xserver-xorg-input-all
and
sudo apt-get install --reinstall xserver-xorg-input-all
both didn't work for me, even after restarting my laptop.
I tried to find which input devices are being used using the
xinput list
command, and got this:
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PixA琀 USB Optical Mouse id=11 [slave pointer (2)]
⎜ ↳ SIGMACHIP USB Keyboard Consumer Control id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ TOSHIBA Web Camera - HD: TOSHIB id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ SIGMACHIP USB Keyboard id=12 [slave keyboard (3)]
↳ SIGMACHIP USB Keyboard System Control id=13 [slave keyboard (3)]
↳ SIGMACHIP USB Keyboard Consumer Control id=15 [slave keyboard (3)]
I don't really know what are the master and slave devices or what are the virtual core pointer and keyboard but I don't think the built-in keyboard and mouse appear right? There are only the USB mouse and keyboard.
I'd like to ask for your help about what I can do to investigate more what's happening and eventually solve the issue.
Thank you!
