You have been subscribed to a public bug: OS: Ubuntu Linux 10.04LTS final release. Fresh install 30th April 2010. Laptop: Fujitsu Siemens Amilo Pi 1536 Video card: ATI mobility Radeon X1400 No third party video drivers installed. Without second monitor, the laptop-screen looks fine. 3D compiz works smooth. Colors are fine. In 9.10 the laptop screen and a second monitor worked fine too.
Problem occurence: When plugging in a second monitor (HP1530) in the DVI-bus on my laptop this is recognized in the ' Monitors' preferences' applet. The second screen shows the extended desktop with regularly appearing distortion stripes (like "shocks") in it. When trying to shut the HP1530 off with the 'Monitors' preferences' applet, the laptop screen distorted. (The screen image shifts right; the colors are mixed/the resolution is bad). When I restart the laptop everything is looking good again. Trying to reproduce the error, I plugged the monitor in again. ( again in the DVI-bus on the laptop with DVI-cable). Now the monitor says ' input signal out of range' and no image appears on the monitor. I try to change the frequency in the Monitors preferences applet. (In 9.10 all frequencies worked fine.) The monitor says "Cable disconnected", but Ubuntu still extends the desktop to the second screen. The 'Monitors'-applet still recognizes the HP1530 second screen. I change the frequency again. The laptop screen distorts like before. In this distorted screen I am filing this bug. This bug looks a bit like: Bug #556232 "Radeon HD 2600 - Dualscreen problem" Bug #533269 "External display not working" Bug #544525 "[RV380] dual monitor not working - M24 1P [Radeon Mobility X600]" I decided to file it separately, because it has some differences in appearance and onset. Looking at the other bugs it could be a linux kernel bug or an xserver- xorg-video-ati bug.
