I am trying to make the screen resolution sticky. I am a long term user of Parallels Desktop Mac V 2 for running windows XP. A long time ago I starting using VMWare V 2 for Ubuntu. I want to consolidate so I wanted to try Parallels Desktop Mac 5 for Ubuntu. So I down loaded a trial of PDM 5 and got the latest Ubuntu 9.10 from the Ubuntu website. I installed PDM 5 and it went ok. I then tried to install U9.10 from the ISO and it was kind of strange. The screen resolution on my MB is 1280x800 but the window opened by PDM 5 to install U9.10 was huge - about 1/3 taller and 1/3 wider than the screen. This required me to cmd+alt to move the sliders around to answer the questions. Eventually i got U9.10 to boot and I got Parallel Tools to install (I think because the cmd+alt reminder in the status bar is gone and the mouse cursor moves in and out of the vm window fine.) When the machine boots it defaults to 800x600 resolution. In the Display Preference I get no other resolution/size options. I can drag the lower right corner and resize. And this makes a new entry in the resolution/size options in Display Preferences (in fact I can drag and release the lower right corner and make what seems to be infinite resolution options for Display Preferences.) But when I turn off the machine and resume, it defaults back to 800x600 and the other options are gone. What is going on?
