QS57/HD Graphics support?

QS57/HD Graphics support?

[-- Attachment #1.1: Type: text/plain, Size: 1424 bytes --]

Hello,

I'm trying to get up and running on a Toshiba Libretto W100, A dual
touchscreen device(Detailed specs:
http://cdgenp01.csd.toshiba.com/content/product/pdf_files/detailed_specs/libretto_W105-L251.pdf
)
I've gotten the first screen to work perfectly, however the second screen is
now the issue.
Enabling LVDS2 via xrandr turns the screen on and extends the desktop,
however all that is outputted is grey, occasionally white, and sometimes
flashing colours.
For information: A fresh install of Windows 7 can't use the second screen
either, until the Intel drivers are installed, so I'm assuming that this is
simply not supported in the linux drivers.
Does someone with more knowledge have any recommendations, I'm at a loss for
how to continue.

Output from xrandr:
#xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 600, maximum 8192 x 8192
LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 0mm

I am sorry to say that the code is riddled with assumptions that there is
just one LVDS panel. Most of the work would be in splitting those
assumptions from the global path and moving the register/mode setting into
per-LVDS connectors. Of course this is complicated by the fact that some
LVDS state is mixed in with more global registers, but that is a mere
complication. Fortunately Arrandale is more flexible in this regard, but
the code needs to support all generations. Again, we may want to split the
code up further.

In essence it is not a lot of work, just fiddly wiring up the second set
of registers and breaking some of the assumptions that only one panel
exists. If you want to tackle it yourself, all the information you need is
in the PRMs on http://intellinuxgraphics.org/

/me orders one for himself.

Ok, the device is configured differently to how I was expecting. It uses
SDVO to drive both LVDS (which I should have guessed given the drivers
report of 2 LVDS). At first glance, we think we are driving both panels,
i.e. we've attached a crtc to each and a bound the fbcon framebuffer to
both crtcs, yet only one panel is active. The likely suspect is inside
intel_sdvo.c.

A different adventure than the one I was anticipating. Perhaps this will
be my wayland test bed...

Hi Chris,

I'm having the same issue on my Libretto W100 with Ubuntu 10.10. It would
be great to have this working. If I can help in some way, please just let
me know.

Thanks!

Woohoo! It was the FDI m/n calculation that was at fault. Will tidy up and
post patches after some sleep.

Bah. Pushed the patches to drm-intel-staging. And now I am definitely
going to collapse from exhaustion.

Of course I'm more than willing to test it, however I need some
hint. I've downloaded the drm-intel-staging snapshot from git
and I tried to compile the drm module against my current kernel
headers, but I get the error "unknown field 'cmd_drv' specified
in initializer". Should I build the full kernel?
Sorry if the question is naive, but I'm not very familiar with
this. I'm running Ubuntu 10.10 with the latest 2.6.35-23 kernel.

Thanks,

Alberto

Yes.

Fantastic! Works like a charm. The libretto just got 100x more useful.

Alberto, just to let you know I had it working under Ubuntu 10.10
(Specifically the netbook remix) earlier today. Build the full kernel
and everything is sweet.

I did notice some weird happenings: Turning on/re orientating the
second screen caused the brightness of both screens to drop
dramatically. Rebooting fixed the problem though, and both screens are
lit just fine now, and seem to be staying that way.

Hi Matthew, thanks for the hint. I managed to compile the kernel
and indeed the second screen is now happily on. However, it is by
default upside down. I can of course rotate the image, but the
touch coordinates do not rotate with screen and behave as if the
screen were still upside down. Do you have the same issue? Also
I'd like to understand whether I can use the rotation sensor to
put the screens in portrait mode like in Windows. After that I can
move completely to Ubuntu.

Thanks,

Alberto

Got it, will do that.

Dear Chris,
I'm glad to hear that managed to fix it. ( also read your related post at http://
article.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/2539/ )

Will this fix be included in a mainstream kernel anytime soon, or is each user 
supposed to apply the "patch" themselves? I'm not very knowledgeable in these 
things as you might guess, but I'm eager to get Ubuntu up and running on my 
Libretto w100.

thanks / Anfanglir

It's in the 2.6.37 kernel. Expect your distro to pick it up sometime, or
use one of the bleeding edge repositories.

OK
thanks! I'm trying it out on Ubuntu 11.04 (alpha) with manual install of 2.6.37 
kernel.

I have no idea, but I guess the developers would be interested in the
versions of the software you use.

If nobody responds you should open a ticket in the bug tracker [1].
