For SDL I usually use the -no-frame option which gets rid of all the window decorations. IIRC there's also a magic key combination (ctrl- alt-f?) to switch to real full screen.
-- implement true fullscreen https://bugs.launchpad.net/bugs/613681 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: New Bug description: Please implement a fullscreen functionality (similar to the one found in vmware, where there is an autohide bar), that enables display of a 1920x1080 VM on a 1920x1080 (for example) without resizing (currently the menubar prevents this). Thank you.
