Linux, capture mouse cursor?

[Brasem]

Hi,

First of all, a big thanks for making this game available on Linux. I am running a dual screen setup on Ubuntu 12.04. When I launch EU4 it completely fills the left screen, just as I would like it to. Everything works fine, but I have problems with scrolling. If I move the cursor to the left edge of the screen, the view port moves left, just as expected. But this doesn't work on the right side of my screen. The cursor just moves from the left screen (where the game is) to the right screen, which is just another desktop. So I have to be very careful to exactly place the cursor on the right boundary of the left screen if I want to scroll right. Otherwise the cursor ends up on the right screen and nothing happens.

Is there something I can do to prevent this from happening? Is it perhaps a Linux steam option? Or something that lets EU4 capture the mouse cursor and I press some key combination to release the cursor so I can move to the right screen?

EDIT: I have a NVIDIA quadro 4000 graphics card and according to steam I have the newest drivers.

cheers!

EDIT: I attached a picture, as it probably explains things better. The left half on the image shows my left screen, where EU4 runs. The right half shows my second screen, where in this case nothing runs. My mouse can cross the boundary between both screens, so I cannot scroll to the right in EU4 as my mouse moves outside of EU4

does anyone have an idea?

DO I understand your post correctly that you have multiple desktops? If so I cannot confirm since I have not used multi desktop on Linux for a long time.

I have two physical screens, and EU4 appears on one of the physical screens (left screen). The mouse can move freely from the left physical screen to the right physical screen, and because of this I cannot scroll the map to the right.

is noone else playing on a linux computer with a 2 screen setup?

I can confirm that I deal with the same thing myself. I am not aware of way to make the game capture the mouse to prevent this. You have to hold the mouse close to the right side of the screen just before it moves to the right monitor and it will scroll. Kind of annoying but works just fine.

It is possible indeed, but very annoying. I'd be surprised if there is not a workaround

I'm going to bump this thread too. I've just started playing EU4 on linux and I have a 3 monitor setup and typically want to play the game on my primary, middle monitor, which means I can't move either right or left without going outside the game.

Worse still Ubuntu/Linux/X Windows doesn't handle 3 monitors on 2 video cards very well, so the left monitor is a different X screen (for those who don't know the details of X configuration this won't make any sense) and when I move the mouse back to the primary X screen keyboard focus doesn't shift back unless I move focus between 2 different windows on the primary X screen. So this makes game play really annoying. (I have to leave another window of something open over on my right screen and mouse all the way over there and back into the game again to get the keyboard back.)

I've been looking for a third-party app or compiz plug-in or something to try to fix this but I haven't been able to find anything. Apparently it's up to the app itself to lock the X cursor using the xlib call XGrabPointer to lock the cursor itself. Since EU4 [understandablely] isn't open source we have to wait for Paradox to implement this in EU4. Ideally there'd be a button combination (using something like, say, the scroll lock (ScrLK) key) so we could lock/unlock the mouse freely during gameplay.

On my home machine I only have one monitor and used to play in fullscreen, so everything was cool.

But I've started doing some streaming and my recording software doesn't work with EU4 fullscreen, so I'm playing in a 1918x1018 window and also having issues with scrolling (it works if I move the mouse slowly to the edge of the screen but not if I move it very quickly.

Therefore, yes, some method to lock/unlock the mouse to EU4 would be appreciated.

If there's no way to do this in Linux itself, then what you're asking for is an enhancement to the game. Best then to start a new [Enhancement Request] thread in Bug Reports with a good description of the situation/problem and any supporting material that might help.

FTR I always use the arrow keys to do significant map scrolling. This works well for me because I use the mouse in my left hand, so the right hand can be on the arrow keys almost all the time.
