Linux Game launches on secondary display

Avatar

  • Completed - Resolved

My setup on Ubuntu, my displays are primary 1920 x 1080 and Secondary 1200 x 1920 (portrait mode). The game no matter what I do launches on the secondary display in 1920 x 1080 and being as it is a portrait display I can only see a slither of the game screen. I cant even read the setting menu because it off the side of the 1200 wide portrait screen.


I now have close to a dozen linux steam games and this is the only one that insists on launching on a secondary monitor.


I've reinstalled the game. Reinstalled Ubuntu 14.04 / 15.04 and are now on 15.10. Same problem everytime.


This has been the case for me since beta. I just gave up on the game and check sometimes when I feel like playing and its still broken.

Hey Marten,


I have made a special build of the game for you that hopefully fixes part or all of your issue. You can access this build by opting into our beta branch as instructed below.


Right click the game in Steam and go to Properties. In the Betas tab, type in the password 'publicpassword' and hit Check Code. Select the 'publictestbranch' in the dropdown box above and then close the window. Steam should perform an update.

I am sorry for answering late, but we have no Linux experts in the core team and we struggle right now to get in contact to experienced Linux users in our volunteer QA Team.
However maybe things which can be done on Windows translate to Linux, I just hope.
1) In Windows you can drag a pragram in windowed mode to any screen and then you can toggle it to fullscreen.
The OS remembers the screen the program was last running on and will always automatically start it on this one.
2) A second solution is to create a shortcut for the game (with steam) and drag it on the screen the program should open.
If the shortcut is opened from the wanted screen, this same screen is used to run the game by default.
3) At least in Windows its possible to hold down the right SHIFT key while clicking on "Play" in Steam. Just hold it down until a little configuration window opens which allows to select screen, set resolution and indowed/fullscreen mode before the game starts it self.

In Windows once you switched the screen successfully once, the program will always open on the same screen until the screen is manually switched again.

I hope any of this helps for now.
We still try to get hold on a Linux expert who should be able to help better.

Cheers

With dancing around I can get it full screen but everytime I start the game I have to mess with it to get it going. Watch this

?
Just start the game with this parameter and then select your first screen.

I tried the launch options.

-adapter N Does nothing it launchs on the secondary display reguardless. I tried N=0,1,2

-show-screen-selector I have a DVI0 and DVI1 to choose from which works but the resolution is still messed up even when I select 1920x1080. The windowed check box did not work. It was always full-screen mode. I tried lower and higher resolutions to test, all have the same messed up partial screen viewable only.

It should at least work if in-game settings and what is set in the config window does match.
Did it match and it still didn't work?
If so, this is very strange, could you then upload your Player and Launcher logs as described here:

?

after seeing the prefs file I manually editied Width and Height to 1080,1920. It did no work and was reset to 1920,3120 after I launched the game.

<<pref name="Screenmanager Resolution Height" type="int">1920</pref>

<pref name="Screenmanager Resolution Width" type="int">3120</pref>


Note that the 2 displays are 1920x1080 and 1200x1920(portrait). The game is somehow trying to flip the resolution added the total width of screens 1920+1200 as the height and vertical 1920 (from second display) as the width.

Hello again Marten B,
just for future bug reports:
There is an "Insert File" button (paperclip symbol) above the text area for your post, which allows to attach a file without bloating the bug report with a plain text copy. This was also mentioned in the link "How to report a bug" a posted above.

OK this issue is odd indeed.
I am still no Linux expert but let me elaborate.

So you say you have two displays:
1) Primary 1920 x 1080
2) Secondary 1200 x 1920

Now the question is:
Why does the operating system report to Unity3d that you have a display of size 3120 x 1920?


It looks like Unity3d is seeing your both monitors as only one single screen.
Did you setup your system to run dual screen mode?
So that you only have one desktop which does stretch over both displays or do you have separate desktops for both or a desktop only on the first of both screens?
If the former then Unity3d just sees one display which consists of both screens, but seems not able to handle this case correctly.

What happens in log:

"requesting resize 1920 x 1080

requesting fullscreen 1920 x 1080 at 0 Hz
Desktop is 3120 x 1920 @ 60 Hz"

So there is the second issue: Why does Unity3d request "fullscreen 1920 x 1080 at 0 Hz"?
I am unsure why this does happen, while it should request "1920 x 1080 at 60 Hz" and not "at 0 HZ".
But I guess the engine is just confused with this artificial "3120 x 1920 @ 60 Hz" dual display screen and fails to recognize it properly.

Since the requested resolution can not be provided by the OS multiple other things fail in result:
"Changing real window size to 1920 x 1022
Ignoring window size change to 1920x1022 : waiting for fullscreen at 1920x1080"
Which will never respond.

So long story short...
Somehow the OS reports one big screen consisting of both monitors to Unity3d engine.
It looks loke you did setup your displays in dual mode?
Can you check this and if, can you try to set them up as separate desktops, so both monitors are recognized as individual screens?
Can you check if you have setup anything else which would merge both monitors into one screen for the game.

I hope we can find the root cause of the problem.
Cheers
