Note: This article is probably outdated. I received reports that simply restarting the vmtoolsd service doesn’t work anymore.
Due to a bug in current versions of Manjaro, it is not possible to change the screen resolution if Manjaro is running as a VMware guest. Neither changing the resolution manually nor using the “Fit Guest Now” option is working correctly. Since the screen resolution is pinned to 800×600 pixels, it’s almost impossible to properly use the VM. I was able to reproduce the issue with my VM running Manjaro with the KDE desktop.
