After installing nvidia 390 drivers I rebooted to find my screen locked to a 1280x1024 resolution, with no option to change it. What should I do?
Which nvidia card do you have? Don't you have the options to change the resolution in 'Nvidia Settings'? If you choose third party software for graphics and Wi-Fi hardware when you install eOS 5.1 therer's no need to install the driver manually and it will install the correct driver.You may have installed the wrong driver.
How did you install the nvidia driver?
