I'm seeing this issue on a Sony Vaio laptop with the same graphics chipset, Intel 4500MHD. The model number of the laptop (in the UK at least) is VGN-SR19XN.
As Daniel describes the splash screen displays fine, then when X starts you see nothing but a blank screen. X has started though and you can hear the Ubuntu desktop startup sound. You can see that apart from this little (!) issue the driver is working fine by plugging in an external monitor (in Ubuntu 8.10 Beta). Even the desktop effects work beautifully. But the laptop screen is completely black. I have tried with Ubuntu 8.04.1 and 8.10 Beta live CDs. 8.10 Beta uses xserver-xorg-video-intel version 2:2.4.1-1ubuntu6. I've included my Xorg.0.log from booting 8.10 Beta. I can't see anything glaringly obvious in it. ** Attachment added: "X log from booting 8.10 Beta" http://launchpadlibrarian.net/18305167/Xorg.0.log -- X fails to start with intel 4500MHD GMA https://bugs.launchpad.net/bugs/268615 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
