@Roxas84 Does your notebook have an Nvidia video card?
I can't be sure, but, researching about it, I only see users who use Nvidia graphics cards reporting "HDMI1 disconnected" problems (on Linux, I didn't find a similar report here on the forum, but Recalbox is based on Linux, comparison), see:

https://forums.developer.nvidia.com/t/hdmi-output-missing-in-xrandr-command-and-external-monitor-does-not-work/68011 https://forums.gentoo.org/viewtopic-t-1090914-start-0.html https://unix.stackexchange.com/questions/81822/hdmi-not-detected-by-xrandr https://forum.manjaro.org/t/xrandr-says-hdmi-is-disconnected-for-external-monitor/28445 https://www.linuxquestions.org/questions/slackware-14/xrandr-reports-hdmi1-being-disconnected-when-it's-connected-4175479547/

I can't tell you that any of these solutions work in Recalbox, probably not, but you can try it if you want.

I believe your problem is a type of driver incompatibility, and if that is the case, there is nothing you can do.

But, I'm not a developer, I can't say much, the most I can help is up to this point, I don't have enough technical knowledge to help you further.

@Zing all is working perfectly now. Thank a million

Hi @terri123

Nice trick! thanks for sharing.
I'll take a look at the documentation and check for this.

@Zing

Ok thank you for the Answer.

@dj_lithium I don't know the model, I don't know if the video card is compatible with Recalbox, although most notebooks are. (I’m not saying it’s not supported, but I can’t guarantee it is)

Hi,

Sorry for the delayed response. There is an image called x86_64. This is the one I used as the CPU on the laptop is 64bit. However, it's not a very powerful one, just Intel Celeron single core - the laptop has 2Gb of ram. It may be that it is simply incompatible (it's not on the compatibility list though that's far from comprehensive), or that the laptop isnt powerful enough. At least I know it does work on some laptops - what spec is yours?

Cheers

I was able to do it! My steps:

ssh on my recalbox cp /etc/X11/xinit/xinitrc ~/.xinitrc add this to /recalbox/share/system/.xinitrc
xrandr -s 1920x1080 uncomment the following line and put my laptop screen :
xrandr --output eDP1 --off reboot!

So i got to the point where i needed to download the ftp clients i downloaded a couple such as filezilla and winSCP and I cant connect even after connecting wifi to recalbox. Im at a loss was trying to get this done for the holidays and play with family.

Any help is greatly appreciated

I did it a while back. I actually preferred to have it on my USB stick, for a whole host of reasons not really relevant for this thread.

Anyway, I am not in front of my recalbox, so I'm going from memory. I believe you need to go to system settings, select whatever recalbox lists as your hard drive, and you select it. Restart the computer back into your OS (Windows, for me). On the C drive, there should be a folder called recalbox. Place your ROMs in their respective folders in the roms folder. Reboot back into recalbox and your ROMs should appear. Let me know how that works for you.

Hi thanks for your quick answer.
Unfortunately there is no option in BIOS related to GPU.
I've just read on some linux forum that the parameter could be saved and need a restart to order.
So i will try to boot an OS from USB, load Optimus and restart on recalbox.
I'll keep you advise.

yo tuve ese problema con una net pedorra q le puse batocera y cuando voy a la configuraciones me daba la opcion de elegir la salida vga auxiliar y con un convertidor de vga a hdmi y lo usaba con una tv por hdmi y despues de unos dias como magia esa opcion desaparecio, solo daba video por la pantalla de la net, cuando voy a las opciones de video para cambiar la salida nuevamente a vga solo te permitia ponerlo en automatico o una opcion q decia LVS1 o algo asi q no servia para nada porq no hacia nada basicamente.. lo q hice fue al encender la net bajo la tapa y automaticamente empieza a dar video por la salida vga nuevamente y cuando enciende voy a las opciones de video y guala aparece otra vez la opcion de elegir la salida vga auxiliar cabe mensionar q fue batocera no recalbox pero como nadie dio una solucion a este tema y veo q es viejo ya porai esta data le sirve a alguien

@ehfred this is a batocera archive. We're Recalbox, not batocera. Please go to batocera support, or install Recalbox.

Probably you should try first if there's any output from VGA only (no HDMI adapter). Maybe with a monitor or other tv if you can.

Also, try to stop ES via SSH with "/etc/init.d/S31emulatiostation stop" and start ES with "startx". See the verbose if there's any info about resolution or something.

@josklown said in Problem with screen cut on laptop with Projector:

TENDRAS ALGUN CORREO UNDEPENDIENTE PARA PODER ENVIARTE MAS INFORMACION, PORQUE EN EL FURUM DE ME PERMITE NI ENVIATE IMAGENES PARA QUE VEAS QUE ES LO QUE ME SALE EN SUPPORT CON LUJO DE DETALLE! incluso hasta video para que sea mas facil

@pceslayer Yep, I guess so!... I'm going to have another crack at it tomorrow. I'll update you if I find anything.

@sauromayne I have the same problem

@userreddit anyway if you want to plug directly your pi to your laptop through an ethernet cable, you need:

a crossover ethernet cable (not a standard cable because there is no swtich between the 2 machines) to setup a dhcp server on your laptop
