I'm having very annoying issues with KDE & the display resolution. Anytime I restart Kubuntu the resolution is reset to 800x600 when my monitor supports 1920x1080. I have to log into all the user accounts and re-adjust the resolution then proceed to re-adjust the panel sizes.
No matter what settings I change, even the default resolution, KDE seems determined to keep the login screen at 800x600 so it's a tiny square on my monitor.
Help much appreciated
