Have this issue with Ubuntu 11.04. Toshiba Satellite L645 laptop and Intel Integrated Graphics display.
I can get a temporary workaround by doing the following: 1) Open the laptop lid 2) Fn + F5 to scroll vid-modes, switches to "duplicate display", output fine on both heads but not desired res. on external. 3) Monitors > uncheck duplicate display, move external to primary position > Apply 4) Set desired resolution on external display > Apply 5) Turn off laptop display > Apply. Everything OK. if 3, 4 and 5 are done in one step, it seems to hang X in a black screen state w/ only mouse cursor visible. When I reboot or detach/reattach the external monitor, I get a purple wobble or blank screen on the external monitor and have to repeat steps 1 through 5. Sometimes I have to kill X to get back up. Is this an issue only w/ 64-bit Ubuntu? I'd happily switch to the 32-bit version to avoid it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/614238 Title: Intel Core i3 External Monitor Wavy Output -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
