EDIT: I just figured it out on my own. In VMWare you should put the video card settings to Auto-detect settings. Now there is no freezing anymore when setting a new resolution.
I saw many questions here facing this issue and I tried as much as I can do with my limited knowledge about Linux to solve this issue for me, but nothing worked so far.
I've installed the latest Linux Mint (Sarah; 18) on an VMWare server. Everything went fine, I can use it. The only problem is - as I pointed out in the title - that the resolution of Mint isn't automatically adjusting to the window of the VMWare itself.
I'm using the vSphere Client to access my Linux VM. I can click on View > Fit Guest Now to let VMWare do the job, but nothing but a small shake is happening to the window.
When I try to set the resolution under the Display option of Mint itself, the VM just freezes and I have to restart the VM.
I used sudo apt-get install open-vm-tools open-vm-tools-desktop to get the package that's doing the job actually.
I'm not sure if I've set up the VM properly. Maybe there are some small but important options I configured incorrect?
And I did updated as much as possible to have all latest libraries and stuff.
Because of this problem I cannot access the OK button on the Update Manager window.
