Hi, all.
I have a Lenovo ThinkCentre M700 that I would like to move from Win11 to Linux. Most of my experience has been with Debian without a GUI, but I want this to be a desktop machine.
With Win11, I have 3 screens active. 1 on each DP connection using a DP to HDMI converter, and a third on a USB port that has an HDMI output. All 3 work.
When I installed Debian (switched drives, so I still have my Win11 drive), I cannot get anything more than a single screen to wake up. I'm using KDE Plasma with X11. I alsop tried Wayland, but it didn't help. There are other reasons I prefer KDE and X11, but I can make changes if needed to use something else.
I had Claude helping try to figure it out, and ended up exercising xrandr a lot. I manually added a new_mode for the screens, adding it to the outputs, there were startup settings made in GRUB. I can plost the chat log if anyone wants to see it or if it is relevant.
Bottom line, screens 2 and 3 never came out of sleep mode. Those were connected to a DP and an HDMI on the USB port.
Other info: Intel graphics adapter. i915 driver installed properly
Display Settings in KDE never showed more than a single display.
Is Debian the right distro? Should I look at Ubuntu or Mint? Does anyone have ideas on how to make this work? What is frustrating is it just turns on and works in Win11, so the hardware is functional.
I'm happy to answer any other questions in my quest to make this work.
