have toshiba tecra a11-11q. after hotplugging external monitor through vga, i have no signal message on that screen. xrandr:
here everything seems to be fine. krandrtray also shows that external monitor is operative.
after rebooting computer both monitors work, but i can't change brightness on lvds.
i'm running archlinux, but the same results were on fedora, ubuntu and mint. there is no such problem on windows xp.
maybe it is not supported yet for Core Processor Integrated Graphics, but i couldn't find such information.
