Originally I installed LINUX MINT Cinnamon 22.3 and all worked extremely well this was on JAN 5 2026, Installed a series of updates and everything was fine. Installed the last update and it changed everything from the font size and type of font to startup and now I have only use of one (1) display monitor whereas both were working without an issue before. Both are working fine and and are plug in properly and have power. I can not seen to add a second monitor. Please advise, thanks
