[virtualbox]: make gfx work normal in virtual machines #86

Closed star-buck closed 8 years ago

star-buck commented 9 years ago

Errata quote: "for unknown reasons X/installer/sddm refuse to start in virtual machines (tested with vbox and kvm). the ISO therefore only does something useful when used on bare metal"

It's a bug in virtualbox. https://www.virtualbox.org/ticket/13615

Comment 1 suggests a workaround that might work.

Bug comment #17 claims it's a bug in Ubuntu. Seems like bug ping-pong :-(

hsitter commented 9 years ago

Isn't that resolved in 15.04 now?

star-buck commented 9 years ago

since i rarely test in Virtual machines, I cant really say...

mgraesslin commented 9 years ago

By pure chance I tested today and it's terrible. The guest extensions are not installed by default and it falls back to llvmpipe, which gives a rather sluggish experience everywhere.

Then I had the stupid idea to install the guest extensions, it gives you OpenGL, but it's so broken that nothing really works. I got a small KWin debug output visible and it was all over "called in this method didn't do what I expected". Looks like the driver announces GL extensions which it doesn't do.

On the VirtualBox I'm now using an OpenBox session as I wasn't able to revert to other settings easily.

Well, virtualbox always has been terrible which is why we originally decided that the team should test bare metal as much as possible ^^. BUT getting a sluggish experience in virtualbox is better than what was the original problem of epilepsy-rainbow-techno-mode as seen here https://www.virtualbox.org/ticket/13615

So yeah, I am pretty sure the original issue here is fixed in 15.04 final. That's not to say that the virtualbox experience is enjoyable though.

New images have worked in new virtualbox for me

closing this now unless hearing otherwise.
