I installed a new linux guest in my VMWare Vsphere 5.1 enviroment. This guest is a Ubuntu 13.04 Desktop.

Ater the installation of VMWare tools I wanted to change the resolution because now it is 800x600. I cannot change the resolution cause then the system hangs. Except changing it to 1024x768 it works. If I change it to a higher resolution it also hangs if i apply the resolution. VMWare tools should normally manage the resolution.. What is wrong here?

The display is displayed as "Unknown" under the display menu in Ubuntu.

Kr,

Try typing in terminal: xrandr -s 1360x768 or whatever your resolution is.

    type in xrandr without any parameters and it will show you what are the possible resolutions for your device/system.

I increased the assigned graphical memory of my VMWare guest to 8 MB and then it allowed me to select the higher resolutions. A lower setting for the GPU memory will restrict you to lower resolutions only.

I had the same problem. I had been trying everything but eventually tried the xrandr option - the command itself failed and I remembered this could be due to available memory. So I added memory (to 4GB) for the VM and the problem vanished.

I had had a lock-up and crash recently (which pops up as a cause on a similar question) so all I can only think is that the memory got reset and I had not noticed.
