screensaver starting while playing planetpenguin racer

Yes, this is another one of the fullscreen applications that is broken with gnome-screensaver.

This bug is a duplicate of Bug #33734 in gnome-screensaver (Ubuntu): "screensaver locks planetpenguin-racer".
However, I can't mark it as a duplicate of Bug #33734 since that bug is already (wrongly in my opinion) marked as a bug for a more general one (bug #32457).

Sorry for the double post

Confirmed in a clean Dapper Flight cd 5 install

This bug is a bit more problematic than others, because after the screensaver starts, the user is sent back to the desktop while the game is still stealing mouse input (you can mouve the mouse but clicking doesn't do anything), only the keyboard is useable.
Unless we can assume normal user are able to kill planetpenguin racer from the command line (I know I can't), that's going to be hudge when people will have the feeling their computer is locked, or when they still have some unsaved work and no other way than to restart X (at best, if they know how to do it) or hard reset the machine (for most newbies).

There is a patch for this on the gnome bugzilla (bug #342728). Maybe it could make it's way into to Ubuntu version?

I don't see how this is related to gnome bug 342728, but since ppracer uses libsdl, this IS a dupe of bug #32457.

For comments about gnome-screensaver and losing mouse control, see bug #48108.

I know it doesn't seem very related, but the 'screensaver starting with SDL games' bug on gnome bugzilla was marked as a dupe of that one, and there is a patch which says:

Updated patch for 2-14. This is already in HEAD.

Note, these changes also fix the problem where the warning fade-out occurs when
playing fullscreen games. In that case the game grabs the keyboard so the
screen can't be locked so we shouldn't do the warning fade at all.

This sounds like what is happening here.
