Hi, after updating, I noticed this at the end of pacman: use mhwd-gpu to set mesa as default: ‘mhwd-gpu --setgl mesa’. Rashly, I went ahead and did so. Now, reboot gives me a black unresponsive screen. I cannot get a terminal. I dual boot and from Arch, I can access logs. I believe that Xorg.0.log tells me what’swrong:
