Bug#905000: minetest: does not use fullscreen resolution over VGA

[Phil Morrell]

Package: minetest
Version: 0.4.17.1+repack-1~bpo9+1
Severity: normal


Hi,

With my current monitor the maximum resolution is not autodetected, so I
have configured xrandr to add a new mode and this works perfectly for
lightdm/xfce.

Unfortunately, minetest somehow does not find this configuration so
always shows the titlebar unless I drop the resolution to at most
848x480, which is then really blurry. Additionally, the desktop
resolution is not reverted to the previous setting when quitting.

Hi,

I'm not sure if minetest is to blame here. This could also be an
underlying issue in the Irrlicht engine which minetest depends on.
Perhaps you can create a new issue at
https://github.com/minetest/minetest. I'm quite sure they are more
likely to help you. This doesn't sound like a Debian issue for me at the
moment and should be better raised upstream.

Regards,

Markus

thanks

As discussed with upstream in #7689, this is yet another symptom of poor
fullscreen support that would be best solved by implementing borderless.

(Dear bot, I don't believe this has been fixed upstream ;-))

The bug has been closed upstream, but i could not find any fixes associated
with them. On top, upstream seems to be reluctant to implement "boderless windows" support,
despite this is the (usual) way how to handle it… Sigh. I guess this is nothing we can
fix from Debian side…

Upstream seems to suggest to use windowed mode and then use DE means (e.g keyboard combination)
to switch that window to fullscreen. This only works if fullscreen mode is disabled in
~/.minetest/minetest.conf -- the default value is "disabled".

(FTR, in GNOME you have to set the keyboard shortcut in the Settings first, as it is disabled
by default. Afterwards, that shortcut will maximize the minetest window as expected.)

I'm downgrading this bug and leave it open to document the workaround.

Cheers,
