Black Screen in Ubuntu 13.10

[jean-christophe manciot]

Environment: VirtualBox 4.2.18 on Windows 7 host - Ubuntu 13.10 Guest

I used to run Ubuntu 13.04 on the same environment without ever such problem.

This black screen happened during qemu 1.6.1 compilation, which I have already performed without any issue on previous Ubuntu release.

When I move the mouse, the screen flickers between black and the wallpaper.
When I don't touch either the mouse or the keyboard, the screen is completely black.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

@Ubuntu Foundations Team Bug Bot (crichton) and John Kim (kotux) : Thanks for taking the time to answer; I have uninstalled the offending qemu package. Besides, I won't test that environment again, especially because I have now a native Ubuntu 13.10 system (not "VMed"), and I will try to compile and nstall a newer qemu package on it. I'll let you know if I experience similar issues.

@Joseph Salisbury (jsalisbury) : thanks for your answer. same as above +:

3.14 is not yet stable. I have already installed 3.13.6 on my new native Ubuntu , and I have boot problem with:
- an endless purple screen on the first boot, but I have access to the grub menu on the second boot right after the first one. Yes, I know, it sounds strange!
- choosing 3.13.6 leads to the same endless purple screen; I suspect issues with the video driver (Nvidia on my system)

Luckily, I can still boot with the old 3.11 kernel. But this release has old buggy drivers.... Speaking of which I do not understand why it is so complicated to install proprietary drivers such as Nvidia graphic ones.
