#8055: Screen goes black at end of boot unless safe mode is selected when Haiku is a guest under VirtualBox on Ubuntu 11.10 -------------------------------------------------+------------------------- Reporter: Don Quixote | Owner: nobody Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/Graphics | Version: Keywords: VirtualBox, virtualization, Ubuntu, | R1/Development 11.10, Oneiric Ocelot, video, vga, safe mode, | Blocked By: MacBookPro1_1 | Has a Patch: 0 Blocking: | Platform: x86 | -------------------------------------------------+------------------------- Hot Damn, I finally got VirtualBox to boot Haiku off my USB stick! That will allow me to build to a partition on the stick, then boot my MacBook Pro off that same partition. Once I got the USB drive working, VirtualBox otherwise seems to work a lot better than Linux QEMU KVM. I am running Haiku r42888 that I built myself. {{{ $ uname -a Linux frylock 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux $ apt-show-versions virtualbox virtualbox/oneiric uptodate 4.1.2-dfsg-1ubuntu1 }}} VirtualBox does not allow one to select different video card models in the GUI as can be done with virt-manager with Linux QEMU KVM. The only options are the amount of video RAM (6 MB in my case), 2D accelleration (disabled) and 3D accelleration (disabled). When safe mode is not used, the screen goes completely black at the end of boot, however Haiku has not crashed as evidenced by serial port output appearing now and then. I finally got video by selecting both safe mode and video safe mode. I will try each one individually and will add a comment to narrow down the problem. I thought at first the problem was somehow due to booting off my USB stick, but I think now that some recent change to VirtualBox that is in Ubuntu 11.10 but not 11.04 must have caused the problem. The host is a Core Duo (32-bit, not Core 2 Duo) Apple MacBook Pro, Model Identifier MacBookPro1,1. I get the black screen with and without IO Apic, and with the USB stick being mapped to either an SATA or IDE drive as seen from the Haiku guest. -- Ticket URL: <http://dev.haiku-os.org/ticket/8055> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
