Last weekend, after normal updates on my Ubuntu 22.04 lts, my monitor just went "no signal" and blue screen. I have an rx6600, the default drivers that come with ubuntu for radeon. I have an hdmi port in my gpu that I ran a hdmi to dvi cable to the monitor (monitor has dvi and vga hookups, 1080p at 60 hz max). I tried resetting gpu, checking other hdmi port on gpu, checking power to gpu (fine). I plugged the hdmi cable from my gpu to the hdmi on my mobo and it picked up the integrated graphics, for now (although, when it suspends, the screen doesn't turn on, despite the computer starting, so after suspend, I have to restart computer). This is all new since last weekend.
Is this just a driver issue?
