Display driver fails to load in Win10 since upgrading guest additions to 7.0.6

Post by reno08 »

Hi,

I have a Windows 10 64-bit VM on a macOS host in Virtualbox 7.0.6

I previously had guest additions installed (I can't remember which version as I don't often use this VM) and everything was working fine.
I made the mistake of upgrading them to 7.0.6, and since then Windows complains that the "display driver failed to load", and falls back to the generic driver.
The display settings are 256MB video RAM and VBoxSVGA, 1 monitor. The VM had 4GB ram.

I can work around this by disabling 3D acceleration : the driver then loads again, but things are much slower than before (even dragging windows around feels painfully slow and non accelerated).

Any tips ?
Thanks

For problems with 7.0 graphics or seize-ups:

7.0 is still in bug-hunt phase, and graphics had a code change.

Please upgrade to the latest 7.0 Virtualbox, Extension Pack if used, and Guest Additions.

If this does not get a stable VM, try switching the 3D acceleration setting (off > on or on > off). If that stabilizes the VM, please note that this happened.

Please create a ticket in the Bugtracker with the problem description, the manufacturer and model of the host PC's graphics card, the graphics driver version (on the host OS), and a (zipped) VBox.log file.

If your host OS is Linux, please provide a zip file with the output of the 'vulkaninfo' command in the Bugtracker ticket, too. (on Debian/Ubuntu/Mint hosts, you may have to install the vulkan-tools package).

Then you could downgrade Virtualbox, Extension Pack and Guest Additions to 6.1.something, or at least the Guest Additions. 3D acceleration won't be possible if you only downgrade the GAs. For full 3D acceleration using the old stable code, downgrade all three.
