[SOLVED] LM VM runs in Software Rendering Mode after Updates

Postby keyneom on Thu Aug 28, 2014 9:12 pm

I believe that I was previously not running in Software Rendering Mode (my VM has 3D Acceleration enabled), but for some reason after doing some updates recently I noticed that after reboot I was only able to go into Software Rendering Mode.

Any ideas or help on how I might figure out which package is causing the regression, and maybe how I might be able to roll back to ensure my 3D Acceleration is working?

you probably will have to reinstall the guestadditions, boot your VM, click on devises and insert guest additions cd, then in the VM run the installer, this will reinstall the correct graphic card driver.

Known bug.

IIRC you just need to avoid updating mesa packages and your Cinnamon VM will be fine.

true for 4.3.10 but then it's just better to update to 4.3.12 anyway.

Awesome! Thanks for the help. Looks like these are the likely cuplrits:

014-08-28 10:37:54 upgrade libgles2-mesa:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:54 upgrade libegl1-mesa-drivers:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libwayland-egl1-mesa:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libegl1-mesa:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libgl1-mesa-glx:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libgl1-mesa-glx:i386 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libglapi-mesa:i386 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1
2014-08-28 10:37:55 upgrade libglapi-mesa:amd64 10.1.0-4ubuntu5 10.1.3-0ubuntu0.1

I'll look into rolling them back to the previous versions. Thanks again!

Looks like the haskell-platform package requires the newer version. So I guess it's software rendering mode for me until a fix comes out.

You can also try to get virtualbox-guest-dkms / virtualbox-guest-utils / virtualbox-guest-x11 packages from Ubuntu 14.10 repos (version 4.3.14). But I'm not sure whether this might pull some additional packages or not.
