It's a fairly minor problem, but it's pretty annoying all the same. Whenever I start up Arch (DE is xfce) in VB, it always defaults to a small resolution after I login with slim, which uses the full resolution that the window allows it. I then have to change the size of the window to get it to fill it up again. Mint, my other VM, doesn't require me to do this. Edit: I forgot to mention that I have installed the guest additions and have them set up as per the instructions on the wiki.
