I also have this problem with Hardy 8.04.1 on my Toshiba laptop (Portege R200), which didn't have this problem in Feisty and the i810 driver. It has the additional problem of confusing KDE into thinking my external monitor is displaying two screens, which leads to lots of interesting effects. For example, the screensaver displays on "two" virtual overlapping screens on my external monitor. I also have the option to display my wallpaper on these two virtual screens overlapping each other on the external monitor.
I can confirm that the xrandr command given above eliminates this problem. However, I'd rather not have to manually turn off the laptop screen, when in the past it was off by default when an external monitor was attached on boot. Also, in the past, the "toshset" utility would switch off the laptop screen, both via the command-line and the Fn-F5 button sequence on the laptop. However, now it just dims the laptop screen and thus the problems listed above occur. Ideally toshset should be able to turn off the laptop screen via the xrandr method - both from command-line and the Fn-F5 button sequence. -- laptop screen remains on with external monitor and lid closed https://bugs.launchpad.net/bugs/145501 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
