I just switched to Linux and I have an annoying issue. When using two monitors (main monitor and TV) after login my main monitor turns off. The only way to turn on the monitor is by starting the TV. When the TV starts it sends a signal to my main monitor and wakes up.
Another weird thing is when I lock the screen (Win+L) if I start, the TV will also send a signal to my main monitor and wake it up.
Main monitor is connected using DVI and it's seen as #2. The TV is using HDMI and is seen as #1. This is how the GPU is made, it's the same on Windows.
System info:
Ubuntu 21.10, Wayland, Kernel 5.14.21 (was the same with default kernel), GPU AMD HD7750 forced to use amdgpu driver in grub:"radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1"
Is there a way to fix this or can I set a shortcut to turn on the monitor after login?
Reset to default
