The problem seems to be solved for me after performing the following steps which are a combination of littleendians solution and a post from unknown47 in this forum entry: http://ubuntuforums.org/showthread.php?t=1743301.
1. Goto edit-mode in grub and add "acpi_osi=Linux" to the line that says "... quiet splash ..." 2. Now you can boot into ubuntu. To make this grub change persistent edit the /etc/default/grub. Change the "GRUB_CMDLINE_LINUX_DEFAULT" line into GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash acpi_osi = Linux" 3. Execute sudo update-grub2 4. Add "setpci -s 00:02.0 F4.B=00" to /etc/rc.local and to the scripts in /etc/pm/sleep.d. Added this line always at the beginning of the scripts. 5. Reboot and everything should be fine.... so far -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
