Hey all,

I'm setting up xbmc on a AT5IONT-I board running Wheezy latest. Getting the Nvidia drivers going was fun - and now I'm almost there. This tutorial seems to be the most recent for a similar setup, but there's not much detail in there.

Currently, I can startx and take control of my monitor over the HDMI connection - but I get this when I run xbmc:

Code:

Error: unable to open display
XBMC needs hardware accelerated OpenGL rendering.
Install an appropriate graphics driver.

Running glxinfo returns the same first line, unless I run it like this:

Code:

glxinfo -display :0 | grep render

In which case I get the following:

Code:

direct rendering: Yes
OpenGL renderer string: ION/PCIe/SSE2
    GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image,
    GL_NV_parameter_buffer_object2, GL_NV_path_rendering,
    GL_NVX_conditional_render, GL_NVX_gpu_memory_info,
    GL_OES_depth_texture, GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,

So I'm trying to figure out how I can specify a display number to xbmc. Any ideas, experts?

Cheers

xorg.conf ?

The only bit I changed from the default is this:

Code:

Section "Device"
    Identifier     "NVidia ION"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option         "HWCursor" "False"
    Option         "NoFlip" "False"
    Option         "FlatPanelProperties" "Scaling = Native"
    Option         "DynamicTwinView" "False"
    Option         "ConnectedMonitor" "DFP-1"
    #Option         "CustomEDID" "DFP-1:/etc/X11/edid.bin"
    Option         "NoLogo" "True"
EndSection

Bump. Anyone got an idea where I could start with this?

[john.cord]

DFP-0 not DFP-1... try this

[alfton]

under the "Module" section, be sure that it contains a line:
Load "glx"

(http://wiki.debian.org/NvidiaGraphicsDrivers)


Section "Module"
Load "glx"
EndSection

(I can recal this problem my self when i had debian installed)

[mafro]

Thanks guys.

@John.cord: I tried DFP-1 - this made no difference. I've commented that line out now as I don't see that it's doing anything for me.

@alfton: The Debian wiki says to add that entry *if* you have a Module section in xorg.conf. Mine didn't have that, so I tried adding it anyway. It didn't work either

Surely there's some obvious answer to this... The thing works! XBMC just doesnt know that it does..

[alfton]

If im not mistaking here, I think you missing some packages, to get the gl going, I can clearly remeber i had the same problem. have you installed the nvidia driver directly from nvidia not the aptitude way?

I can also remember some problem with conflicting driver with the X11 that i needed to blacklist to make it work.. Sorry its a long time sins i installed the wheezy on my box so i dont remeber what it did to make i work.

(I know its posible to make it work becouse I had it up runing)
hmm, maybe some symlinks that helped xbmc to se that it is there...Sorry I dont remeber

another thing, maybe you have this bug? http://bugs.debian.org/cgi-bin/pkgreport...t=unstable

[mafro]

alfton, thanks for your reply dude.

I think I know which driver thing you mean when you say blacklisting - it's the removal of the "nouveau" driver which isn't going to be any good until Wheezy is stable. I've followed those instruction to get off nouveau and onto the non-free nvidia driver already.

I haven't tried installing a driver direct from nvidia, but I'm pretty sure I don't have to.. Because it does actually work! .... But only when I specify "-display :0" to glxinfo.

Who knows who to inform xbmc to look in that location.... I might do some hacking this weekend.

Any more posts are welcome!!

xbmcs startup script calls FEH.py, which in turn does this:

Code:

glxinfo | grep "direct rendering"
direct rendering: Yes

if the output is not "direct rendering: Yes", it will throw your "XBMC needs hardware accelerated OpenGL rendering" error.

[mafro]

Thanks wsnipex.. As in the OP, I receive that very error. However, I can run:

Code:

glxinfo -display :0 | grep render

So my question is really what config do I need to make :0 become the default? (Or similar).

[mafro]

I finally figured this one out - and of course it was pretty obvious really. When you understand what's going on

In my case, I'm running xbmc on a headless machine. Debian Squeeze to be precise, with no window manager:

"The current configuration is a HTPC running Debian Squeeze, with no window manager installed. The main goal here is to start an Xserver only for XBMC. It allows also to specify which user will start / own the XBMC process. This method will not work if you have a window manager installed"

Maybe that will help someone if they find this post

Hello,
I am having a similar problem. But I could not make out the solution from the link you mentioned above. Can you share the update that you did?
Thanks

[mafro]

I literally just created the init script as supplied in the wiki. Then run /etc/init.d/xbmc start

What happens for you? What's the output/error?

Sorry for late reply, I didn't have notifications on..

[upcominggeek]

well, I finally gave up on this and installed openelec. Interestingly, that one worked smooth like a butter and my external monitor is behaving as a good boy. And one guy had created an addon for opera browser which truly fulfilled all my needs of an htpc! Here is the link for the opera add-on for openelec that works with no hiccups - http://dl.dropbox.com/u/8224157/OpenELEC...index.html
Thanks mafro for the response anyways.
