Try this: https://wiki.archlinux.org/index.php/bum...eo_tearing

it's a bumblebee issue (e.g. nvidia in combination with the installed intel gpu) - if you can completely disable the nvidia card and use the intel funcationality.

How can i disable nvidia card and use intel? I uninstalled nvidia drivers completely and rebooted, which left me with basic drivers and sluggish gui, as i understand this processor comes with a GPU, can it be that the intel GPU is disabled?

Basically i am using this laptop as an HTPC , Being a linux noob, i opted for Kodibuntu as it starts Kodi automatically. Are you saying that i should change the default Kodibuntu setup and install a window manager then run Kodi?

You still can configure it to start its own session but with a window manager. I am saying that Kodibuntu just configures it the wrong way for what reason ever.

Install openbox, then logon to the desktop session and select openbox as window manager. Try to run Kodi in this session.

EDIT: ^^for testing

I will try to find out how to do it.

Is there something in bios? Cause the userspace process is not that straight forward: https://github.com/Bumblebee-Project/bbswitch

Please post dmesg | pastebinit before doing anything.

Don't waste your time on this optimus/bumblebee crap. The HDMI port of your laptop is wired to the discrete gfx card, Nvidia. I would be surprised if that was not the case. Bubmblebee would allow to use integrated gfx and output via discrete gfx. But this is what you want to avoid.

Most probably. I have the following observations:

- OpenELEC 6 will only detect a graphics card if legacy version is used (6.0.3). Otherwise setup wont run. This tells me the intel card is not active, i could be wrong though
- Kodi shows audio output as hdmi nvidia, no hdmi intel

Your NVidia gfx is legacy. You should install driver 340.xx, NOT 304.xx (as shown in your log file)

In my first post i've mentioned that i have tested also 340.96 and the result was same so i rolled back to 304

Right, but there are many variables and ruling those out only by one narrows down the issue. I have installed 340 myself and don't observe tearing.

Ok so i am back to 340.96 now. Trying to use a window manager, however, if i Exit Kodi, output on TV shows blank white background with Kodi logo. How can i login? Laptop screen is damaged so thats not an option.
I think i need to alter display settings first which i cant.

here is a photo of how my tv screen looks like when i quit Kodi.i also notice that the tv changes resolution.

Code:

when Kodi is on, i do the following:

Code:

xrandr -display :0 --output LVDS-0 --off

to turn off laptop display and Kodi resolution is shown properly on TV


after quitting Kodi, if i enter same commands on SSH, i get following error:

Code:

Invalid MIT-MAGIC-COOKIE-1 keyCan't open display :0

so in my efforts to solve why the login screen is not being shown, which i suspected due to laptop display is the one active, i have come accross the following link:

http://askubuntu.com/questions/679934/ho...-hdmi-only

i had to change device identifier to "Card0", edit my xorg.conf file and reboot. now if i quit Kodi i can see the login screen. wow! finally!

ok then i thought, let me test a video, see if it solved tearing as well, and tearing is solved. to further make sure, i renamed xorg file and rebooted, tearing is back again. i restored xorg file and rebooted, tearing is gone. issue solved!

thanks for the support guys!
