Using xrandr disables keyboard/mouse/touchpad input on Lenovo Ideapad 330
by feb11 from LinuxQuestions.org on (#5EWSE)
Debian 10 stable buster
kernel 4.19.0-12-amd64
The problem: in X-window, any of the following two commands
Code:xrandr --output eDP --brightness 0.35
xrandr --output eDP --mode 1024x768disable keyboard/mouse/touchpad input (I still can move the mouse pointer but clicks don't have any
effect). Which makes X unusable and I have to kill xorg from another terminal.
Related packages that I installed:
firmware-linux firmware-linux-nonfree libdrm-amdgpu1 xserver-xorg-video-amdgpu
firmware-amd-graphics libgl1-mesa-dri libglx-mesa0 mesa-vulkan-drivers xserver-xorg-video-all
xserver-xorg-input-synaptics
(Prior to installing them, xrandr wouldn't work at all, "unknown gamma" message or some such)
I wonder what the problem is and how I can fix it
Thanks
