Hey all;
Ran into a snag, and found a resolution that I'd like to share. My particular situation is that I have a standard PC running in headless mode, which then runs VirtualBox clients. The physical computer is literally sitting next to my entertainment center in the living room, hidden behind my kids toy rack.
I've been having an issue with the Win2K guest not displaying at anything above 1152x876 or whatever the res is, while using GUI mode. I'd have the same issue with RDP and LogMeIn not allowing me to resize the screen above that res. I ran all the setextradata and setvideomodehint commands I could find to force the screen res to 1280x1024x[256-32bit] all to no avail. I could go LESS than 1152x876 at ANY colour mode, and the screen resolution would change instantly, but could not go above. I could also force the screen into full-screen mode and I'd get the full desktop to work at 1280x1024xANY, but while in a RESTORED WINDOW state, that is, not a MAXIMIZED window, I couldn't push above 1152. The video memory I had set was up to 32meg. Now its at 16meg, and I may drop it to 8meg. Come to think of it, I can't be sure if I tried to manually resize the RESTORED window. It may have worked, but, it'd be a pain to have to log into the host to resize the screen.
So what I did was installed a service called LogMeIn, which I have running on every other Windows machine I use, and then on the host, ran the guest in VRDP mode. Giving the guest some time to start up, and with the video memory set to 32meg, I was able to get the screen resolution up to 6400x1200x32-bit. The NICE thing about LogMeIn is that it will resize the display on the fly, so at 1280x1024 on my main machine, I could successfully see and move the windows around. GFL on reading what the windows said. ;) With RDP, you get whats set for default, and it doesn't scale your screen! JUST FYI!
I installed LogMeIn as I sometimes may need to get to the host, or guest machines while not sitting in a computer physically in my LAN, and I can't be bothered to setup a VPN, or have the desire to open ports. LMI gets around pretty much any firewall, unless specific ports are blocked.
