At the very least you'd need to modify the X driver, and doing it optimally from performance POV would require even more changes. So xrandr on Harmattan is more like 'xonlyoner' ;-) Well, somewhat, but the r left is actually the rotate, not resize. Let me explain. There was some problem with pvr memory management, so resizing the X screen is disabled by default. IIRC we added some xorg.conf option to allow it, but there's a good chance of making a mess of things if you try it. What you could do is start X with a larger screen size (eg. 854x854), and then you could safely rotate the LCD output. TV output rotation isn't really possible since VRFB (tile based hw rotation engine) isn't used. If you attempt to use non-VRFB based rotation (aka. DMA rotation) on the TV output, the display controller is likely to fail since the DMA can't keep up with the display refresh due to the non-tiled memory layout. The third way to rotate would be using the GPU, but no one ever bothered to implement that in the X driver. There are other things you can do with the current xrandr support. For example you could use a bigger screen size, and pan the LCD and TV output viewports to non-overlapping positions, which would give you independent content on each output. There are going to be problems with touch coordinates though, and the WM doesn't know how to the handle the situation either. Also page flipping only works as long as the window size equals the screen size. So there is a fair bit of xrandr functionality in the driver, but it's not utilized by the upper layers. The main reason for that was that the UI designers wanted the transitions to be glitch free, and there just wasn't enough time to make that happen with xrandr. -- Ville Syrjälä syrj...@sci.fi http://www.sci.fi/~syrjala/ ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

What do you think? Sounds good. We don't really need a harmattan specific GUI repo, at least yet. The standalone Qt GUI should work in both fremantle and harmattan if the tvout-ctl API is the same. Some clever way to handle packaging may be needed if there are differences. Perhaps keep the packaging stuff in separate branches and merge master to them when the actual code changes. I now merged both Xv and XRandR codes to libtvout-ctl [1]. I changed the license of this library to LGPL 2.1. There's a configure option to select the backend at build time. The debian packaging will build the Xv backend. I'm not quite sure how I'll sort the issue on how to build for harmattan. The same packaging otherwise works for both platforms, so it would be nice to have some decent way to detect the platform during the build and use that to select the backend. It would avoid having to duplicate the packaging and maintaining multiple branches. Run-time backend selection would be another option, but seems a little pointless considering you have to build separate binary packages for each platform anyway. I updated both maemo-tvout-control and n9-tvout-control to use the new library.

[ANNOUNCE] N9/N950 TV out control application

The backend supports a few extra knobs, when compared with fremantle. However, I was too lazy to write the extra GUI code. So the current GUI offers the same controls that maemo-tvout-control has. The ultimate plan is to write a nice QML GUI for this stuff, although I don't know when I'll have time to learn QML. Another idea I have is to move the backend code to a separate library. The same should be done for the fremantle Xv based backend code.

Sorry. I created new tvout status menu plugin, it is in that CSSU repository too. Great. Multiple different GUIs was the reason I tried to keep the backend code separate. It is possible to merge my changes on CSSU to your project? I think it is not good idea to have 2 separated projects which has same code. Yeah we could do some merging. But perhaps now would a good time to move the backend code into a separate library. I'm not sure if the harmattan and fremantle code can coexist nicely inside a single library, or if that would cause problems with the packaging and whatnot.

The scale and aspect ratio options are especially helpful and let me finally watch videos full-screen on my widescreen VGA monitor (using a Composite-to-VGA converter box). The only unfortunate issue is that some combinations of settings simply don't work. Usually it just leads to a black TV out signal. That's caused by the display driver disabling the overlay used for TV out, when some hardware limitations would be exceeded. Would you care about packaging it up and uploading it to Extras? If you need help, just tell me, and I can assist with packaging and uploading. I'm too lazy to bother with packaging and whatever else is needed to upload it somewhere. I would prefer if someone else could take care of such things. Thanks, Thomas PS: Is the TV-out control panel applet that's included in Maemo open source? If so, we should probably add the scale and aspect ratio options there as well (now that there's some working and tested code that does just that) and distribute it through the Community SSU. I don't remeber if it's open source or not. IIRC the control panel applet just frobs with some gconf key, and it's some other component that notices the change and communicates it to the X server. One option would of course to replace the control panel applet entirely. Never written one of those but I doubt writing one is very difficult, assuming that the APIs are public. It wouldn't be very difficult to turn my plugin into a daemon + plugin, where the plugin would just play with some gconf keys, and the daemon would take care of the Xv stuff. The Xv and GUI parts are split fairly cleanly, so adding something between them should be quite easy. Also the same abstraction would allow other GUI concepts to be implemented, eg. a HD status plugin, or a regular GUI application. I don't have the motivation to do any of that ATM.

Is this a limitation of the N900's hardware, and independent of the connected device? Yeah hw limitation, although the checks in the display driver are a bit off actually. So it's possible the driver may reject some settings that should be OK, and it's also possible it might allow some settings that aren't really guaranteed to work. If so, we can probably get the parameters via trial-and-error and disable non-working combinations in the UI. We can't really do that. Whether or not some settings work also depends on the size of the input picture, and with videos the input size can be pretty much anything. But right now, it's not that big of a problem, as one can just pull back the scale value until the picture comes back. Yep.

Sometimes that is rather frustrating when you're working on something in one target with multiple sessions open and then you need to switch to another target just for a quick test (or something). In that case you need to close all scratchbox sessions before you can actually switch the target. The chrooted way should probably allow more than one active target.
