[Q] Using Laptop's Display to use Raspberry pi - Raspberry Pi Q&A, Help & Troubleshooting

I am new to RPi. I use a Asus ROG laptop which has an HDMI port. I bought a Canakit Pi B+. It has a preloaded micro SD card. I am trying to boot up the Pi. I dont have a monitor. When I connect the Pi to power source and the HDMI to laptop, it doesnt show up. I also have a WiFi dongle and not using a ethernet cable.
Is it possible to directly use the laptop's display for connecting to the Pi ? I am running Win8 on my laptop.
Guide me to any tutorial that uses the laptop's display to boot raspberry Pi.

Wait, did you just say you are connectinf the raspberry hdmi output to the laptop hdmi output?

Yes. I understand it is the output port. But is there any other way for using LAptop display to boot the Pi or is it mandatory to have a monitor ?

That depends on your laprop display, not the raspberry.
Npw i wonder if you broke something with thar connwction.

OMG.. thats not good news. Broke what ? fired the socket or something ?

Even thought i doubt it, the port coukd be fried (or something like it)
Start reading about the capabilities of your laptop

I've alternative suggestion if you want to display what RasPi show to your computer, but it'll need a network connection between your computer and RasPi. You didn't need to use the HDMI cable.
If you've learned about linux and ssh, you can use SSH & X11 forwarding.
SSH used for commandline remote via network, and X11 forwarding for run X11 session in laptop.
If you're using windows, you can use Putty for SSH client, and XMing for X11 forwarding management. I don't know about Mac or Linux, because I've never tried before.
X11 forwarding is different from remote desktop protocol, team viewer, vnc, etc.
AFAIK, X11 forwarding is like.... when you start SSH session from your computer (as SSH client), and in SSH session you run a X11 desktop app (like firefox, gedit,etc), or run X11 session (startx), it'll forwarded into your computer and display that X11.
Correct me if I'm wrong.
Press thanks if you want

possible to enable usb tethering on HP touchpad?

hi guys,
i'm on the cm9 rom now and would like to make use of the "reverse tethering" app to leech my fast desktop connection via USB, so that i can sync files faster through dropbox.
to do that, i need to have USB tethering enabled on HP touchpad. would this be possible?
anyone?

If your desktop is connected via Ethernet but has wireless capabilities there is an app for PC's called connectify that can make your PC a wireless hotspot .

What exactly is your setup is your desktop connected by Ethernet to a wireless router, how is the tablet connected.
what is that you are trying to achieve, the more info you can give the easier it will be for me to replicate and hopefully come up with an answer.
regards
my hp touchpad can connect via wifi, but it's a lot slower than a wired connection. i want to try achieving FULL/near full speed download on my hp touchpad, by reverse tethering to the desktop's ethernet connection.
the desktop is connected to the wireless router through a powerline adapter, i.e. wired ethernet and is achieving full speed on its own.
One thing to note is that you'll not notice too big of a speed boost if you are connecting to the internet. The reason being, your ISP has a throughput speed of say 25 MBits a sec down and 5 up (In a hypothetical situation). Your wireless is usually up to 54 (on wireless G), and wired is either 10/100/1000 MBits. However, you are still throttled by your ISP, who runs at 25. So tethering via USB won't net you faster speeds to Dropbox, but it might for local network related things, like streaming from a local PC, transferring files, RDP, etc.
Just a thought to share, hopefully it helps.
Oh, and running through the power line like that is a messy way to do it. Home power is noisy and slows down your network speeds. Just sayin', I hope I don't offend.

bump
This is the thread that keeps coming up in google searches, and since it was never answered, figured its time for a bump.
I´m in a similar situation atm, Ive got no access to data or wifi as Im traveling abroad.
Cyber cafes abound, and id love to use this app as well, but.. i get the same error.
Im surprised as id assumed CM would have all such features builtin. No big that it doesnt, im just not sure how to add it.
Any help?
(and yes, ive tried to get the other method working, but having trouble getting adb to detect the tablet, that method works on my phone, but id prefer a method that fakes 3g, since that other method doesnt work with many apps)
The problem is the to connect anything to the TP USB connector and get it to work needs power injected into the interface (hence the need for Y cables when using an OTG cable). This ends up as so complicated, that most give up and decide to use WiFi tethering. Also, I am not sure anyone has found a way to get the necessary drivers into the kernel.

will pwnedcast ROM eventually allow for usb ethernet connection?

I'd love the feature to use my usb ethernet adapter as the main connection for chromecast as it'd help with local streaming and maybe eliminate wireless latency issues
Well, it's been said there is HEC support to get HDMI Ethernet channel. Unfortunately, after a full afternoon of searching, you can't just make a cable. It's a separate protocol and you'd need a chip to translate the RJ 45 into HEC.
Not only that, I seriously doubt those chips are available to purchase in quantities less than 1000

Yeah HEC seems a bit overkill...
USB Ethernet adapter seems slightly more accessible, though only certain chipsets would be supported, and that's assuming there's enough RAM/storage and USB OTG doesn't dumb-down the USB connection any.
For example, my Toshiba Thrive (AT100) has support for a certain vendor's USB Ethernet adapter built into the stock ROM. Very convenient to maximum network bandwidth when I'm using it as a secondary display via iDisplay.
Well, dddtg and I were having the conversation yesterday and it seems the eth0 is supposed to be for HEC

Well that has some good potential then!

At least there may bet possibility of * something * in the future. Better than no mention at all.

as mentioned, me and tchebb believe the chromecast has built in support for HEC networking, as not only does the hardware support it, but a ethernet interface is active on each chromecast with a unique MAC address. We currently do not have the hardware to test it, so it can not be confirmed at this time.
As for USB Ethernet support with a OTG cable, at this time it is not possible. A few things would be required first for it to work:
Enable the USB Interface in the Stock OS with a custom kernel
have the proper driver compiled and added to the kernel, or loaded as a module
Make sure that all binaries in the chromecast could utilize the wired interface
The first part would not be too bad, but the issue is on part 2 and 3. There are many different manufacturers for USB Ethernet Adapters, and to compile and add every single one of their drivers would take loads of space and time.
As for part 3, all of googles binaries, while most open source, require propitiatory binaries that only Marvell can hand out, and as we don't have them if any of the applications are directly linked to the wired interface, there is no way we could easily force them to use a wired interface.
So tl;dr is it possible? yes. Is it easy or worth the work? not really. It would be best to just use HEC if its enabled.
Marvell?? Oh god

Well if a full HEC support was realized it could allow the Chromecast to serve as the Internet connection for all other Network aware devices that are HEC compliant in the home Entertainment system....
OR (and much more likely) Would allow Chromecast to use a wired connection from one of the other devices in the Home Entertainment system as it's primary Network access point.
The goal of HEC is suppose to be that only one device in the HDMI chain actually needs to be connected to the Net, The rest would all connect via HDMI instead.
But if you ask me it's probably a pipe dream to ever see it reach it's intended goal.

Wireless USB adapter in raspbian

Hi
I was using my tenda USB WiFi adapter to connect my raspberry pi 2 to the internet. I was new to raspberry pi and was experimenting on it continuously. Unfortunately while trying to set a WiFi hotspot on my raspberry pi I was interrupted by some errors and tried to rollback the changes manually. Now the USB adapter is not detected by the raspberry pi GUI WiFi manager. I've checked the adapter on PC and its working good. When I use lsusb in pi I still see the adapter connected to my USB. Also the ifconfig lists the wlan0 details.
I am now unable to connect to any WiFi network either by command prompt and GUI. Please help me.
Thank you.

so "lsusb" lists your device, and not just the ports right? Can you "ping" anything inside or outside your local network? It may be that the wireless driver is missing or broken. You can check installed device drivers by typing "cat /proc/devices" in a terminal.

Tiny, Mini-Computer for Router Login under VPN

was wondering if there might be a really small, cheap computer (all i need is remote access to it and a web browser) so i can remote into it and manage a router that's behind a VPN. i guess it would need 2 ethernet ports (or at least 1 and wireless) to access the modem & the router both.
would entertain other solutions, but with mullvad running on tomato, the router ddns settings won't pull the real IP, and uses the VPN IP, and WAN points to another internal style IP (192.168.43.177) maybe this would only apply to using cell phones as the WAN source... but i can't get the router to show the actual IP, so was looking at maybe a cheap mini computer to circumvent that and access it locally once i remoted in the said mini computer.
thanks for any help

Raspberry pi tor router

I have a raspberry pi 3 that I want to make into a tor router to use with my laptop(doesn't have Ethernet port). I have seen tutorials online showing how to do this, but they do not work for what I need to do. What I was thinking of doing was being able to plug the pi into my computer for USB power. Then it would turn on and connect to the WiFi network using the credentials that I would put on there while setting it up. Then it would turn into a tor router and transmit the connection to my computer thru a USB to USB cable. I know that my laptop works with a USB internet because I tethered that way from my phone before. Optionally I would like to be able to prevent connection to certain websites thru the pi. Would anyone know how I could go about doing this. Thank you.
