The above example is *really* meant only for the case when you have some computation going which allows the main loop to be run occasionally so that GUI events (like animation) can be processed. - Eero ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] Toolchain still not working...new clues
Hi, > after lots of tries, I dropped Xnest and tried Xvnc. > It also didn´t worked. I also tested running any X > Application under scratchbox...also didn´t worked. Have you allowed them to connect to the X server (be it your desktop one, or Xephyr)? With Xephyr you can use just "-ac" to disable all access control (and set Xephyr not to accept TCP connections with the standard "-nolisten tcp" X server option[1]). With the desktop X you can do something like: - outside Sbox: xhost +localhost or just - copy the ~/.Xauthority file from your home directory to your home directory inside Sbox Desktop X servers are nowadays normally configured so that they don't allow TCP connections, just local unix socket connections[1]. "sb-init.sh" should be run with DISPLAY environment NOT having the host address part, like this: DISPLAY=:1 sb-init.sh start - Eero [1] This is done for obvious security reasons. X doesn't have any security between the clients, all clients can manipulate each others resources and events as they wish. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Re: [maemo-developers] Happy birthday Maemo!
MoinMoin wiki is ok. Would you also consider switching MoinMoin to MediaWiki http://www.mediawiki.org/wiki/MediaWiki at this point in time. I would be very happy with that. I must confess I am somewhat biased, but I think MediaWiki is much easier to use and pages tend to look better in the long run. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Sort of, vertical blanking occurs when the electron beam retraces back to the top of the CRT screen. And yes it has a dedicated analog line (on a vga/monitor cable, it is shared with the luminance/colour data on a composite signal). > I doubt you will find anything like that > in digital-only LCD circuitry.

As you mention internal TFT/LCD displays use different and usually digital (until the LCD/TFT controller chip) signalling. But the controller chip still receives a "top of frame" or "vertical blank" signal (at least in those data sheets I have read for LCD displays). Anyway I would like to sync the SDL_Flip's to the "top of frame" or "vertical blank" signal. The reason for this wish is, that you really can't do anything animated if you refresh the display at a random point in time. Okay you can, but there will be artifacts, these are caused by the top part of the display containing one frame and the bottom one containing the next frame. For those not familiar with the problem I have attached two tiny programs (compiled for arm) flashingTest. Displays some "random" colours, I wrote it to "benchmark" the graphics performance of the 770 and to detect the native screen format (its 16bit R5G6B5 btw.). It do however show the artifacts. vblSync. Was written especially to show the artifacts. The high DPI of the 770 display makes them less noticeable but they are still there. Oh and for those of you who still have the IceAge2 trailer that came with the 770, the Nokia movie player also shows these artifacts quite clearly in the beginning where there are a lot of panning going on. I can just hope that there are a "hacker" out there who knows how get this kind of "scanline" information out of the 770. Otherwise I'll just have to live with sub Amiga 500 graphics capabilities :) > > - Heike > ___ > maemo-developers mailing list > maemo-developers@maemo.org > https://maemo.org/mailman/listinfo/maemo-developers flashingTest.tar.gz Description: Binary data vblSync.tar.gz Description: Binary data ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

You're sure there's anything like vertical blanking for the 770? My understanding is that VBL is closely tied to the transmission of video data through an analog line. I doubt you will find anything like that in digital-only LCD circuitry. There will, however, be some kind of display refresh which uses some timing of its own. If you look that direction, maybe there's some interval which can be used for similar tasks. - Heike ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] SDL vertical blank (vbl) sync.
Hi I was wondering if anyone knows how to sync. the SDL_Flip to the vertical blanking of the display. While it is nice to get 47+ FPS while memset'ing the display, I would rather be synced to the display and avoid the tearing at the cost of FPS. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
