Public bug reported: (Content copied from "Ubuntu 14.10 ISO live boot ends up with a corrupted display" #13615 VirtualBox bug ticket, by piotrjurkiewicz)
Booting up live session of Ubuntu MATE 14.10 and Ubuntu Gnome 14.10 from ISO ends up with a corrupted screen. See the screenshot: https://launchpadlibrarian.net/186864347/ubu.png Switching back and forth to the tty7 (ctrl+alt+F1 and then alt+F7) fixes the display. I think that this might be a problem with resolution setting: ``` 00:00:31.226379 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=0000000000000000 w=1152 h=400 bpp=0 cbLine=0x0, flags=0x1 00:00:31.226399 UIFrameBuffer::RequestResize: Screen=0, Format=0, BitsPerPixel=0, BytesPerLine=0, Size=1152x400, Sending to async-handler.. 00:00:31.226457 UIFrameBufferQImage::resizeEvent: Format=0, BitsPerPixel=0, BytesPerLine=0, Size=1152x400 00:00:31.226467 UIFrameBufferQImage::resizeEvent: Resizing to FALLBACK buffer due to format is invalid.. ``` After switching back and forth to the tty7 (what fixes the display) the log says: ``` 00:00:31.226379 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=0000000000000000 w=1152 h=400 bpp=0 cbLine=0x0, flags=0x1 00:00:31.226399 UIFrameBuffer::RequestResize: Screen=0, Format=0, BitsPerPixel=0, BytesPerLine=0, Size=1152x400, Sending to async-handler.. 00:00:31.226457 UIFrameBufferQImage::resizeEvent: Format=0, BitsPerPixel=0, BytesPerLine=0, Size=1152x400 00:00:31.226467 UIFrameBufferQImage::resizeEvent: Resizing to FALLBACK buffer due to format is invalid.. 00:01:37.584616 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=0000000000000000 w=720 h=400 bpp=0 cbLine=0x0, flags=0x1 00:01:37.584634 UIFrameBuffer::RequestResize: Screen=0, Format=0, BitsPerPixel=0, BytesPerLine=0, Size=720x400, Sending to async-handler.. 00:01:37.584680 UIFrameBufferQImage::resizeEvent: Format=0, BitsPerPixel=0, BytesPerLine=0, Size=720x400 00:01:37.584692 UIFrameBufferQImage::resizeEvent: Resizing to FALLBACK buffer due to format is invalid.. 00:01:39.055475 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000000a7f0000 w=1024 h=768 bpp=32 cbLine=0x1000, flags=0x1 00:01:39.055495 UIFrameBuffer::RequestResize: Screen=0, Format=843204434, BitsPerPixel=32, BytesPerLine=4096, Size=1024x768, Sending to async-handler.. 00:01:39.055559 UIFrameBufferQImage::resizeEvent: Format=843204434, BitsPerPixel=32, BytesPerLine=4096, Size=1024x768 00:01:39.055568 UIFrameBufferQImage::resizeEvent: Resizing to directly use VGA device content.. ``` I have tested 4.3.18 and also the testbuild 4.3.19 r96825, it happens on both of them.
