Description Alex Deriziotis 2007-11-14 01:35:00 UTC 
I've got a fresh Ubuntustudio 7.10 Gutsy installation, which uses the 1.2.11-9ubuntu2 package.

When playing x-Moto in fullscreen, and the idle-time for the screensaver to kick-in expires, the game snaps out of fullscreen into windowed mode. I can then press alt+enter to go back into fullscreen.

If I disable the screensaver this stops happening.

I've found that the same thing happens on Scorched3D on a vanilla Ubuntu 7.04, but was resolved somewhere in Gutsy, but I couldn't figure out where. Perhaps the Scorched3d developers implemented a fix since I posted on their forums about this.

Someone else has had a similar problem with X-Moto. It went away when he stopped using GNOME. His guess was that a certain GNOME application (the window manager, Metacity, comes to mind) is intercepting key presses for whatever reason, but when an SDL game requests a full-screen window it is no longer able to detect those key presses so it assumes no one is at the keyboard.

When I say 1.2.11-9ubuntu2 package, I mean the libsdl1.2debian (1.2.11-9ubuntu2) package.

Same behaviour while playing Trigger fullscreen (http://sourceforge.net/projects/trigger-rally/)

I think this was a metacity bug back in the days, but we should retest for 1.2.14.

Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).

I believe this is fixed for SDL 1.3, which has a much better architecture for controlling these kinds of things.
Comment 6 Alex Deriziotis 2009-10-21 06:49:41 UTC 
just tested this on ubuntu karmic w/ libsdl 1.2.13, fixed for me. thanks
