Confirmed for TravelMate 5735z with intel gma 4500MHD on Natty 64-bit. The problem does however not appear for me if I already use the backlight adjustment keys (fn + left arrow) during the bios boot screen. The backlight adjustment does however not work in natty anymore.
Adding options "acpi_osi=Linux acpi_backlight=legacy" in GRUB (like in bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/518002) enabled backlight adjustment using fn+arrow keys. This also allows for turning backlight back on when encountering a black screen. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/744187 Title: [g45] Black screen on boot acer travelmate 5735Z, intel gma 4500mhd To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/744187/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
