I think I have a workaround-
the .xinitrc has a line

batocera-resolution minTomaxResolution

that REDUCES the 1920x1200 resolution set previously in the script to 1280X1024, and stops me from setting it manually.
I commented this out and it sets the resolution correctly at startup.

hi all-
I'm running an older Nvidia GT620 GPU on an i3 system. I'm running the latest version of Recalbox, but the setup with the older Nvidia drivers (v390).

I've edited /recalbox/share/system/.xinitrc and set "xrandr -s 1920x1200", but it starts at 1280x1024

as seen in the Xorg.conf log file-
40.217] (II) NVIDIA(0): Setting mode "DVI-I-1: 1280x1024 @1280x1024 +0+0 {ViewPortIn=1280x1024, ViewPortOut=1280x1024+0+0}"

but in the .xinitrc file, I have the "xrandr -s 1920x1200" specified. When I set this to other lower resolutions, the lower resolutions work fine.

HOWEVER, "xrandr -s 1920x1200" from the command line ONLY works if I set a lower resolution in the .xinitrc file first. If I specify 1920x1200 in the .xinitrc file, THEN attempt to set the resolution from the command line, it fails with
"Size 1920x1200 not found in available modes"
Yes, my setup does support 1920x1200- when I specify it manually from the command line (after starting X with a lower resolution)
export DISPLAY=:0
xrandr -s 1920x1200
it sets the resolution correctly (but emulationstation isn't displayed correctly).
Even when I can't set it, the resolution is listed as available with "xrandr -display :0.0 -q"

Any ideas?
This setup worked fine with older revisions of recalbox.

Bonjour- Je ne parle pas français. I am having this problem too. I hope there is a fix for it.

Hi all- I found this solution to my problem, and would like to share it. In Kodi, I scraped my movie collection, and then Kodi wouldn't start, and the RPI wouldn't get an IP address via DHCP. It looks like the thumbnails that were generated by scraping the movies filled up a partition on the SD card. To fix, I reset the Recalbox config (press shift at bootup), and then via SSH made the following changes. edited <span style="color: #222222; font-family: -apple-system, 'San Francisco Display', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 14px; line-height: 20px;">/root/.kodi/userdata/advancedsettings.xml </span> added the following between the <advancedsettings> tags- <pathsubstitution> <substitute> <from>special://profile/Thumbnails/</from> <to>/recalbox/share/.kodi/Thumbnails/</to> </substitute> </pathsubstitution> this forces Kodi to put the thumbnails on the "storage" space of the card.
