problem with trackball/mouse can move outside game/screen/window

IanDaemon

I have not had this problem, although I play full-screen and not in a windowed mode. Could that be the issue?

its possible that it is not, but i somehow managed to start centipede in a 1:1 window and i saw the cursor move off the screen and the movement stop in game, when it hit the edge of the screen.
thats how i know this is the problem.

tbh i would really prefer to just lock the mouse to the current game.
but if thats not possible, how can i force fullscreen?

@Halvhjearne Did you manage to get this sorted?

I have a similar issue where using a trackpad or trackball with Centipede running on MAME 2003 stops moving left around the center of the screen.

Running on laptop PC with Ubuntu.

Thanks

Did anyone find a solution to this issue? I have recently moved my arcade box from a raspberry pi running retropie to a PC running ubuntu and retropie. The trackball is the same. It worked fine on the Raspberry pi, but on the PC, I now have this issue. Its making Centipede and Millipede unplayable. Any suggestions would be greatly appreciated. I am currently in full-screen mode.

@tomguy111 By default, RetroArch doesn't 'grab' the emulator window when is in fullscreen mode and this causes the mouse to move out of the window. You can tell RetroArch to 'grab' the window by pressing F11, but currently there's no configuration to do this by default.
In the next RetroArch version, I think it automatically grabs the window when fullscreen is active, so this issue shouldn't come up.

@mitu hi, thanks for the reply. Is there required timing on when I should press F11? Tried it while in the game as well as while launching. Neither seem to have addressed the issue.

If we're talking about the same issue, then pressing during gameplay should be fine. But maybe there's a different issue, if F11 doesn't solve the problem.

@mitu thanks for your help. Has anyone successfully gotten a trackball to work on Ubuntu/retropie? It’s very disappointing to me and is definitely a showstopper for this platform. I will either have to switch back to the raspberry pi, or find a new platform to go with. I’d be willing to try another pc, reload the system, or other solution, but not sure if this is the recommended platform for a cabinet build running on a pc. Thoughts?

Old thread, old problem. My trackball is hitting a "wall" when moving to the left in a game like Centipede, just like others have described above. I didn't have this problem with my raspberry pi. I just installed Retropie on my Ubuntu system, and I have this problem. Looks like this problem is 2 years, hope it gets solved soon.

Edit: I think the problem is that Retropie is behind in updating retroarch. Retropie is currently using 1.8.8 of retroarch. From reading, looks like 1.9.0 or later has the fix for this. So how soon will retropie update to this latest version of retroarch?

Edit 2.5 years later: Adding video_windowed_fullscreen = "false" worked! (see post below)

@zoyx Try adding video_windowed_fullscreen = "false" to /opt/Retropie/configs/all/retroarch.cfg. This fixed the issue for me on Ubuntu 20 on x64. You'll also want to make sure this isn't being set to true in any of your directory or game specific config files, because they will override this setting.
