Version: (using KDE 4.1.0) OS: Other Installed from: Ubuntu Packages system settings/display has no hardware settings or administrative tab to set the screen resolution. I am stuck at 800X600 with no way to go to 1024X768.
With Systemsettings -> Display -> Size & Orientation you can change size / screen resolution. This is in KDE since 4.1.0. Checked with a Kubuntu Live CD 8.10, works.
