[Qemu-devel] video mode in windows game

I'm trying to get a children's game to work under windows under qemu. When
the game starts, it flipps into some video mode that my monitor does not
support when in full screen mode, but when in window mode its ok. Anyone
know how to find out what video mode is currently in use by the vm? My
suspicion is that its 640x480, but I'm not sure.

Weird. Of course, in that case it shouldn't go into fullscreen mode at all -
it should report the error and go back to the host's original resolution.

The guest OS should tell you. If it doesn't, you can just measure the size of
the window in pixels (when running in windowed mode of course) - the size of
the window will correspond to the resolution that the guest is using.

Not necessarily - especially LCDs can be sometimes very picky about the
modes they support, eg. on one of my computers, a LCD monitor wouldn't
display the BIOS bootup screen anymore (it just showed "Video mode not
supported") after I switched from an on-board GFX card to a PCI one, even
though it appeared identically on an old CRT monitor.

If you take your boots off, you'll never get them back on again.

It's still wrong for windows to try and use modes that don't work.
Windows should know what modes are supported by your monitor and refuse to 
switch to anything else. Sounds like you haven't configured windows 
correctly.

You haven't played with these children's games. Once they start, they change
the resolution and stuff, and there is no going back to the OS until you
quit the game, where up it (usually) resets everything back the way it was.
Unless there is some kind of hacker trick.

Hm, in qemu, how can I send a control-alt-delete to the vm?

I meant qemu/SDL should be able to detect that the resolution is not supported
and refuse to switch.

Ah, ok. Still, a run in windowed mode should tell u the resolution.

"sendkey ctrl-alt-delete" from the monitor.

The sendkey worked, but windows went back into windows mode with the non
game resolution before bringing up the task manager

Only if the host knows the monitor does not support the video mode in 
question.
