Reproducible: Always Steps to Reproduce: 1. Install kernel-default 3.0.1-1.1-i586, kernel-default-base 3.0.1-1.1-i586 and preload-kmp-default 1.2_k3.0.1_1-76.39-i586 from the repository http://download.opensuse.org/repositories/Kernel:/stable/standard/. 2. Shut down the laptop. 3. Dock the laptop, attach external digital LCD monitor to the dock's DVI port and close the laptop lid. 4. Power on the laptop and wait until GRUB boots openSUSE 11.4. Actual Results: For a second, I can see the openSUSE logo. After that, the screen becomes black with flickering pixels in two vertical lines near the left edge of the screen and a short horizontal line in the top left corner. Finally, a picture of 104 or 105 evenly-spaced light greenish-blue stripes on a darker green background appears. However, the mouse cursor is rendered correctly and I can move it around the screen. By pressing the buttons on the external monitor's case I can see from the monitor's menu that the display resolution is 1680x1050, which is the native resolution of my external monitor. The laptop's built-in display is turned off all the time. Expected Results: Instead of flickering pixels on black background, it should have shown the boot log messages. Instead of the green stripes it should have shown the login screen. It is a really good idea that the kernel detect that the lid is closed and keep the internal display turned off and set the resolution to the external display's native resolution, only too bad that this fails (the older version 2.6.37.6-0.7.1-i586 from the openSUSE Update repository just ignores the fact that the lid is closed and turns also the built-in display on and sets the resolution of both displays to the native resolution of the built-in display, which is 1440x900). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
