#13112 worksforme I get an Ubuntu crash report alert related to VirtualBox systematically at every boot teo8976
Description

I had installed Virtual Box on Ubuntu 13.10 or maybe 13.04 and it's been months since the last time I used it. I haven't done anything to upgrade VirtualBox yet. Though I would expect it to get automatically updated as EVERYTHING else does in Ubuntu, I guess it won't, and I guess it will prompt me to reinstall it the next time I run it (that's how it has always worked in the past), but in the meantime i at least expect it to not give me trouble while I DON'T EVEN USE it.

So, Since I have upgraded Ubuntu from 13.10 to 14.04, EVERY TIME I boot, I get a popup of Ubuntu's titled Crash Report, that says that an error occurred while "installing" software, and the package name is VirtualBox (see screenshot).

Actually I'm not sure whether this happens at every boot, or on boot after installing updates that require a boot to finish. I can't tell for sure because i rarely reboot.

#13260 obsolete Virtual box has become painfully slow (Windows guest on linux host) teo8976
Description

I have a Windows 7 64bit guest on an Ubuntu 14.04 host with VB 4.3.14 on an intel core i7 3632QM (this is a quadcore with 2.2GHz)

Simply moving around a window on the guest is panifully slow.

I used to have the exact same version of windows guest installed from the very same installation CD on VirtualBox 3.x on a FOUR YEAR OLD computer wit Ubuntu 12.x and the guest ran much faster than it does now on the newer hardware with newer VB.

Actually I remember it becoming this slow after some upgrade of VB on the old computer, too.

Something has definitely been screwed up somewhere between 3.x and 4.y that has degraded performance to an unusable slowness.

The host suffers too. Right now while the guest is practically idle and about 2% CPU consumption is reported within the guest, on the host the VirtualBox process is consuming 147% CPU (i.e. a core and a half) and afefcting the host responsiveness.

It's surprising to notice such a degeneration after a couple-of-years newer hardware and VB, with teh exact same guest OS (meaning a clean install of the same installation CD). Something must be badly wrong.

Is there anything I can do to figure out where the bottleneck is?

#13282 obsolete GPU tests don't work with WDDM driver teo8976
Description

I installed the guest additions on a Windows 7 64bit guest on Ubuntu 14.04 host, and I chose to install the "experimental" WDDM drivers instead of the "basic" GPU acceleration support.

By the name "experimental" I do expect it to have some issues, but I would expect it to at least mostly work. Something that doesn't even remotely work should not be called "experimental", it should be called "not even worth trying", "not fit for release" or "non-working", to make it clear that it's of interest only to developers that are willing to help fix it, but a complete waste of time to end users.

I've tried some openGL benchmarks such as FurMark, TessMark and GPUTest.

GPUTest crashes as soon as you click the button to start the test. TessMark doesn't even open (I guess it crashes immediately at startup)

FurMark creates a black window (where you're supposed to see an animated 3D scene). If you drag the window around, for each new mouse movement a new frame is rendered which you can see for a fraction of a second, then it's all black again.

Other programs that use graphics systematically crash, e.g. Max/Jitter.
