connecting lappy to tv after having installed bumblebee
 
HI chaps, I have finally managed to get around the installation of bumblebee to allow my laptop running ubuntu 12.04 to connect to the tv via hdmi cable. I think I have done everything I needed http://eternalvoid.net/tutorials/linux-optimus-gt650m/ but what now? I connected the lappy to the tv and I still get a "no signal" message. DO I have to run something when I plug it in? The link above at the very end says something like "If all went well, you can now run programs using your discrete NVidia card by launching them with the optirun command, like this:" so does it mean that I have to launch some program when I use the hdmi cable? ANy idea?
thanks

i think the laptop has to boot up with the hdmi plugged in in order to enable hdmi output. some brands and models of laptop you have to hold down a blue function key and hit f4 or f11 in order for it to switch from the laptop screen to hdmi.

thanks tried all that, no joy. ANy other idea? Is there any output I should check?

jazzo 05-16-2013 04:45 PM

SO I tried to find out what card I have:

The I run

and got a nvidia configuration windows with a message though, saying:
Quote:

You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
Needless to say I tried that:

Why did I get that error?

Can you post the output of lspci?

Yo! man, Have you gone to the display settings in your computer while connected with/to the TV and select detect displays?

Your TV should be tune to the PC also on the remote look for AUX or INPUT and see the input number in the HDMI port

jazzo 05-17-2013 03:28 PM

Yep TroN-0074 all done, no joy. I think there is a problem with my nvidia drivers, I think I must have blacklisted them when I followed the bumblebee installation procedure here http://eternalvoid.net/tutorials/linux-optimus-gt650m/, no idea. I thought the point of installing bumblebee was to get it to work with the tv but I haven't been able to do so. Any help will be much appreciated

Timothy Miller 05-17-2013 07:23 PM

Bumblebee is to get optimus technology to work. The ability to switch between the embedded Intel graphics when doing non-intensive graphics work (basic desktop, internet), and then switching to the Nvidia graphics when the extra graphics horsepower is needed (games, anything 3d accelerated).

jazzo 05-18-2013 06:03 AM

Ok thanks, so I suppose that if I connect my tv to the computer and then try first with the embedded graphics and then to the Nvidia graphics, one of them will work. SO question, how do I find out what I am using and how do I switch? Perhaps
Code:

lspci
tells me what I am currently using (Intel from the output above), so how do I do the switch?
thanks

Timothy Miller 05-18-2013 10:10 AM

Well, it's supposed to automatically do the switch for you when it detects a 3d accelerated program being run. No idea what it uses for detection. As far as using the TV, do you have a hotkey to change monitors (usually FN+F8 or another F-key)?

jazzo 05-18-2013 01:46 PM

eh eh, it should but does it actually do it? No idea.
So does the lspci command helps me to understand whether the switch has actually happened or not? Like if I browser the internet and try to lspci and then I connect the cable and lspci should I get different output?

About the hotkey, well I usually try fn + f8 but don't forget this is a windows machine and then I have installed ubuntu on it, so not all the hotkeys might work.

Timothy Miller 05-18-2013 04:03 PM

The FN + F-keys are hardware keys. It tells the BIOS/EUFI to switch from display 1 to display 2, all the OS is needs to do is be able to detect it. However, not all models do they work with all outputs. I'm guessing there's probably something in the xorg.conf that's preventing it from displaying, but I'm not sure what could cause it.

lspci was just so I could see the full hardware listing of what your laptop had, it will not tell you which is being used, since they're both seen by your OS at all times.

jazzo 05-18-2013 04:11 PM

Ok I see what you mean.

Ok so I wonder whether anybody else has had this problem before, I mean, I am sure somebody did. COuldn't it be that something in this procedure http://eternalvoid.net/tutorials/linux-optimus-gt650m/ hasn't worked? Is there a way I can test both the embedded graphics and then the Nvidia ones to make sure that they work correctly?

TroN-0074 05-18-2013 05:12 PM

I have never had the experience to work with one of those video card but I did a search here are some results

timothy brings up a good point. this is os agnostic hardware related. so from a cold boot do you you see the manufacturers splash screen or even the grub menu on the tv (before the os is launched) ? if not there mite be something in the bios that has to be toggled.

other than that i would try a different tv, cable and laptop to isolate which is faulty.

jazzo 05-23-2013 12:26 PM

HI thanks. From boot I can't see absolutely anything on the tv, everything is on my screen. The thing is, it works absolutely fine in windows (my laptop is dual boot) but not at all from ubuntu. So,I assume there is nothing I could toggle in the bios if it works already (only) in windows?
