Wrong screen resolution

alex-pex

I have a problem with Batocera display (since the first version I tried : batocera-20170219) the image is not fullscreen. I don't know if it's a resolution problem, or a wrong window position.

I cannot use xrandr because it says "Can't open display".

export DISPLAY=:0.0
xrandr

ok. i guess you've a plugged extra screen,
so 2 screens, one in 1024x768 the other in 1360x768.
On both screen, iguess that the resolution 1024x768 is used, then, there is some place left on the screen.

i've not made such configuration automatic or configurable in batocera,
however you can use this thread to fix your problem by creating a .xinitrc file.

as far as i understand,
cp /etc/X11/xinit/xinitrc ~/.xinitrc

edit ~/.xinitrc
and add a line :

xrandr --output VGA1 --primary

and restart, this shoudl do the job.

No I only have a TV with a 1360x768 resolution.
I did have a similar problem with LibreELEC which was solved by disabling LVDS1 https://forum.libreelec.tv/thread-5301-post-36711.html#pid36711 . They said there's a lot of problems with LVDS1 output, and the guy in the link you provided had the same problem.

Anyway I tried the ~/.xinitrc tip, and added " xrandr --output LVDS1 --off " and it's a lot better.

EDIT: I didn't copy the whole file, but :

#!/bin/sh
xrandr --output LVDS1 --off
sh /etc/X11/xinit/xinitrc

i guess that a second output is active, even that's not visible.
can you run xrandr once it works ?

does it work with xrandr --output VGA1 --primary ?
or only with xrandr --output LVDS1 --off ?

LVDS1 connected primary
VGA1 connected

should become

LVDS1 disconnected
VGA1 connected primary

xrandr --output LVDS1 --off

Screen 0: minimum 8 x 8, current 1360 x 768, maximum 32767 x 32767
LVDS1 connected primary (normal left inverted right x axis y axis)
VGA1 connected 1360x768+0+0 (normal left inverted right x axis y axis) 820mm x 460mm
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

it works for both recalbox and kodi

xrandr --output VGA1 --primary

Screen 0: minimum 8 x 8, current 1360 x 768, maximum 32767 x 32767
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
VGA1 connected primary 1360x768+0+0 (normal left inverted right x axis y axis) 820mm x 460mm
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

it works for recalbox but kodi is still off, and switching display using kodi settings will produce a black screen
