can't full screen shown

Post by zhangjie033 »

The VM can't full screen shown, the addtion package has been installed. Only this VM doesn't work, the other VMs worked well. And the "auto-resize guest display" tab is gray, how can I fix it? Many thanks!

Virtual Box: 6.1.4

Reduce vCPUs to 2-4. I'd start with 2 and only increase if I had a guest app that uses additional cores (most do not). 6 cores is unacceptable, as that is 100% of available cores, leaving none for the host.

I can't speak about other VMs that are working, but this VM has 3D acceleration enabled, and there are unsigned NVidia graphics drivers on the host which are probably preventing the 3D feature from working. The following is one of many examples in the log, though they all seem to involve the same DLL.
00:00:05.884945 supR3HardenedErrorV: supR3HardenedMonitor_LdrLoadDll: rejecting 'C:\Windows\system32\nvspcap64.dll' (C:\Windows\system32\nvspcap64.dll): rcNt=0xc0000190

Look for updated NVidia drivers.
