I installed Ubuntu 22.04 on my PC recently as a dual boot alongside Windows 11. When I boot Ubuntu my screen goes black every 15-30 seconds and I have no control. Sometimes the screen lights up again as if nothing had changed and I can type a few things, but soon after that it goes black again.
For context, my computer is a Samsung Galaxy Book2. It doesn't seem to respond to any keyboard input when on the black screen. I think this might be due to the graphics driver. I have Intel Iris Xe graphics, and I don't know where to start to debug this.
Edit 1 :I followed the instructions of this other askUbuntu Question which seemed similar to my case Dual booting Ubuntu help. It didn't solve my problem but now ubuntu stopped doing the black screen and seems to just go in sleep mode every 15 seconds and I have to use enter to bring it back.
