Force lower resolution on x64

farfanetz

I'm trying to force the resolution of 640x480 on batocera for x64.

I'm using an old CRT monitor that accepts higher resolutions, but they all look bad (and the system always pushes the highest one). So my last hope is to fix the resolution on boot to always be 640x480, a spec that the screen can pull off without major problems.

I've edited the file on /etc/x11/xinit/xinitrc with the command "xrandr -s 640x480", but this doesn't provide an immediate result and if I restart the system, my changes are erased and the file returns to it's original version.

I feel that I'm missing a lot of extra configurations that should be done, but I'm clueless. Can someone help?

i guess you're not far.
it's the file ~/.xinitrc to edit.

I just did that, but no success 🙁
My step by step was:
- I copied the xinitrc file to ~/
- Renamed it .xinitrc
- Kept every command that was originally inside it
- And just added the line
xrandr -s 640x480

The system ignores and keeps booting in a different resolution. Something is missing from my side, I guess.

Any guesses? Am I doing this right?

$ cp /etc/X11/xinit/xinitrc ~/.xinitrc
$ export DISPLAY=:0.0
$ xrandr

800x600 60.32 56.25

864x486 60.00

640x480 59.94

$ xrandr -s 640x480 # works, but breaks the opengl window
$ vi ~/.xinitrc
...
/recalbox/scripts/recalbox-config.sh setoutput "${settings_output}"

xrandr -s 640x480 # adding this line

without windowed, time must be sleeped to wait that matchbox ended to initialize :-(

exec emulationstation --windowed

$ /etc/init.d/S31emulationstation stop
$ /etc/init.d/S31emulationstation start
$ xrandr # the value is good, it works.

not for you ?

I'm trying to install the "batoceta" in a notebook and it is not detecting the native resolution of the screen. it starts at 1280x800 and my screen does not support it. I wanted to know how do I change to 1024x768 resolution.
