Hi everyone: I am trying to setup 2 monitors. The hardware is: AMD chipset, ATI video card screen 3 Vga monitor 20" ( 1600x900 ) screen 2 DVI-I to adapter to Vga monitor 14" ( 1024x768)
I can use display and rotation to the following setup: screen3 main monitor screen2 extended desktop
But i have 2 problems and question
- every boot the screen are cloned and not extended.
How i can do to store permanently the extended configuration?
- when the screen are cloned i see well into screen 2, but when i switch to
extended the screen 2 the color are degraded like old 16 ega. How fix it?
Please provide output from the following: xrandr --listproviders xrandr | egrep 'onnect|creen|*' | grep -v disconn | sort -r inxi -Gay
Before running the above commands, update inxi thus:
sudo inxi -U
If you don't, you'll probably get error message(s) from a or y switches. If the command is refused, either update by following the instructions on:
https://smxi.org/docs/inxi-installation.htm#inxi-manual-install
or use the instructions on that site that allow to override the distro's -U switch defeat via an /etc/inxi.conf file.
Note that I don't try to use any DE's screen configurator. Instead, I do it globally via xrandr script in /etc/X11/ somewhere, depending on distro. With output requested above, I can probably make such a script for you.
The colors problem might not be solvable. An old Radeon card might have bad RAM (I seen it quite a bit) or insufficient RAM for the total output space.
