Version: (using KDE 4.2.1) OS: Linux Installed from: Ubuntu Packages I have a laptop with an 1024x768 monitor, and also my video card says that it supports 1024x768 at maximum. So even if I connect an external monitor with a higher resolution, I can only use 1024x768, both in Windows and in KDE. However, in GNOME, I can set it to higher resolutions, and it works finely. (Also, in Windows there is a registry trick to allow other resolutions). A similar feature for KDE would be useful.
Thanks for reporting your bug. Since reporting Krandr has since been replaced by KScreen. It is available in the Plasma 4 series, and is default in Plasma 5 onwards. I hope this solves your issue. If you still have a problem after upgrading please reopen a new bug under kscreen. Thanks
