intel i3 and Toshiba TV 1080i not displayed correctly fallback to 1280x720

[XabiX]

Binary package hint: xorg

Hello,

I have been trying to make this work but for some reasons I can't. I had to install the latest 2.6.33 kernel in order to solve some issues with the i3 and also to support the TRIM on ssd.

The motherboard is a Gigabyte h57 with Clarkdale i3 processor (and on board video). The TV it's an old TV Toshiba 42WLG66 which is max resolution is 1080i.

I tried to force the ModeLine with a xorg.conf file but with same results.

I know also that this "video card" is only supported with intel drivers 2.10 and even better with the latest ones 2.11. Currently Ubuntu delivers 2.9 ones. I tried a ppa package several times which broke my all installation with no more LAN (so for a HDTV PC quite annoying:) )

Any idea or issue spotted?

Many thanks
XabiX

Now if I set a xorg.conf

[XabiX (xabix666)]

here is the log linked to the xorg.conf file attached previously.

What I d like understand is if there is any benefit of waiting for some patches already in the pipe, or if this issue is linked to a bug or if it's a configuration problem.

Many thanks in advance

Hello,

I have discovered that the interlace mode has been developped and just released.

More information available in this thread:
https://bugs.freedesktop.org/show_bug.cgi?id=11220

"Now the interlace is added in the latest Eric's drm-intel-next tree. Will you please help to test whether it can work for you? The drm-intel-next tree can be obtained by using the following command:
   1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel.git
   2. git branch -r
   3. git checkout -b origin/drm-intel-next"

Can this be included in the xorg-edgers releases?
for example on top of 2:2.11.0+git20100606.b586624d-0ubuntu0sarvatt~lucid

Thanks
XabiX

It should be include in the kernel sry :-s

Any news?

[XabiX (xdealmeida)]

If I al correct interlace mode is supported on 2.6.35 kernels.

Info from http://www.gossamer-threads.com/lists/linux/kernel/1233346

Krzysztof Halasa (1):
drm/i915: Add support for interlaced display.

hopefully !!!!

Patch has been posted here:

The kernel side is ready starting from 2.6.35-rc2 now the driver site needs to be updated.

cheers

Hello,

Is this confirmed to be supported on Maverick as Bryce H. added the maverick tag?

Thanks
XabiX

[madbiologist (me-again)]

The maverick tag means that the bug exists on Maverick.

Is this working now on Oneiric? What about on Precise beta 1?

[madbiologist (me-again)]

If it's still not working, there is a patch in the just-released 3.3 kernel to add EDID support for CEA video modes. Several people have reported gaining additional, much wanted modes. A PPA of this kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/
