Re: "I note that the person asking the question seemingly never bothered to create an Ubuntu bug, so it can't have been that important to them." That's not actually a safe assumption at all. Many people are on the clock and are not paid to file bug reports for the rest of the world. As soon they find a work-around that deals with the problem temporarily and locally, they move on. This problem has been reported world-wide in multiple circumstances, and is still happening with 16.04. It just happened to me right now (with the Xubunutu 16.04.1 ISO in a VirtualBox VM). The Right-Ctrl F1 and Right-Ctrl F7 (or "Host" F1, "Host" F7, if you've redefined the "Host" key) trick worked for me in this case, so I'm done with it and getting back to work. It is possible I (or someone in my situation) might remember to try to replicate and debug this problem further for everyone, on a VM at home, on our own time. But Canonical cannot depend on this happening. It's a "bad administrator experience" issue that should be dealt with like any other serious bug.

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.
