Mouse pointer does not appear on full screen

[Yona-TYT]

Linux Fedora 35 on wayland.
When I activate the "borderless" option (full screen) the mouse cursor disappears and I can't use the gui interface.

By the way, this has been around for a long time (perhaps since the "borderless" option was implemented), so it has nothing to do with "https://forum.simutrans.com/index.php/topic,21326.0.html".

Can't reproduce on Arch. Afaik, the "borderless" option on linux is just the "fullscreen" we had before, it was just re-branded for consistency. So that particular change should have no effect. You get the same results if you start the game with "-borderless" or "-fullscreen"?

[Yona-TYT]

Both start without the mouse pointer I'm afraid. I suspect it could be something related to the wayland or gnome composer.

Maybe simutrans should have its own cursor like supertux does ?, I also think I get a similar problem in supertukart (cursor not showing up).

Try to force Simutrans to start in wayland mode, that might help. You can do so starting simutrans like this:

Code Select Expand

SDL_VIDEODRIVER=wayland simutrans

SDL2 still default to X11 in wayland sessions, but that is about to change in the upcoming SDL 2.0.22

Given these problems with Fedore, it is probably good that Simutrans does not find the Libaries by default ...

[Yona-TYT]

Other OpenSource games like Minetest also have problems with full screen mode...

However in penguin (supertux) the course works fine in fullscreen mode, maybe we can learn something from them about the fullscreen implementation under wayland.

Simutrans loads without decorations, however when switching to full screen the cursor is still missing.
The terminal says:

Code Select Expand

Failed to load plugin: '/lib64/libgobject-2.0.so.0: undefined symbol: g_uri_ref'
No plugins found, falling back on no decorations

This must be a problem with you wayland compositor. Under Sway (wayland), cursor is shown correctly. You are going to have more luck complaining to GNOME/Mutter devs.

There shoudl be a flag to activate a softpointer somewhere in simuconf.tab. But not sure if it is working anymore.

softpointer

https://github.com/aburch/simutrans/search?q=softpointer
There it is, unfortunately I'm not compiling simutrans anymore since I lost my hard drive, so I can't test.

Maybe it is convenient to activate it with full screen mode only?.

I have recently switched to archlinux , and am running into the same cursor issue. However now with "SDL_VIDEODRIVER=wayland" it works fine for me.

Even so X11/Xorg still has problems with the cursor. @Prissi is it possible that implementing a custom cursor "like supertux in the image above" will solve the problem?.

Edit.
The cursor is still there (if I use a volume up hotkey, the cursor appears momentarily ) it seems the window is overlapping the cursor for some reason.

I didn't get a cursor anywhere, maybe the code doesn't exist anymore?.

You need to compile with the -DUSE_SOFTPOINTER flag, the feature is disabled by default.

I am having trouble compiling simutrans on archlinux , as I am a newbie in this district.

I wonder if anyone has a command to install all the dependencies. 😅

You can install my package, which should download all the dependencies https://aur.archlinux.org/packages/simutrans-svn

Then cancel compilation step after the dependencies have been installed.

Nice

I have tried this way:

Code Select Expand

# The following useful conditional compilation flags exist
#
# Needed to compile:
# SIM_BIG_ENDIAN: MUST be set for PPC/Motorola byte order! (old mac, amiga)
# NO_INTPTR_T: must be set if intptr_t is not available
#
# Changing appearance:
USE_SOFTPOINTER := 1

But it doesn't work or I'm not doing it right?.

[TurfIt]

Code Select Expand

# The following useful conditional compilation flags exist
#
# In order to use the flags, add a line like this: (-Dxxx)

FLAGS = -DUSE_SOFTPOINTER

FLAGS = -DUSE_SOFTPOINTER


The pointer solves the problem, but it has a graphical error in the pakset selection and load window (I have to report it).


Is it possible to enable it for linux ?, that would be a solution for this problem with full screen in wayland.

As with full screen, a button to activate it in display settings might be a good idea.

I have checked with the latest version of fedora (F38) and its recent versions of SDL2 and wayland, now everything is working as it should .


I'm going to move this as solved.
