I have the latest updated CentOS 7 installed in my virtual box in Mint and ran through the KDE GUI the Guest Additions from the KDE file manager inside the CentOS 7 VM. I cannot change my resolutions at all, not higher, not lower. I am stuck at 1024x768 and my monitor will do 1920x1080. I'm using a pretty old video card but all my other VMs work fine with resolutions, my system is a 4th gen i5 with 32 GB RAM, Z97 board.
I tried this thread:
viewtopic.php?f=49&t=59780&p=252502&hil ... on#p252502
With this line:
Code: Select all
VBoxManage getextradata vboxvm enumerate
There are a number of old posts going back to 2010 and such talking about making changes to X11, but this is 2017 and I don't want to break my VM, I've already done that a couple times messing around with this.VBoxManage getextradata vboxvm enumerate
bash: VBoxManage: command not found
