Through compare the ‘fading’ option and ‘not fading’ option, print the Xserver and Geode-driver debugging information on the SSH terminal. I found the ‘fading’ option trigger the Geode-driver (lx_display.c -> lx_crtc_gamma_set function), but the ‘not fading’ option does not trigger this function.
I had a test, the following change: static void lx_crtc_gamma_set(xf86CrtcPtr crtc, CARD16 * red, CARD16 * green, CARD16 * blue, int size) { unsigned int dcfg; int i; DebugP("lx_crtc_gamma_set /by Hunk\n"); #if 0 assert(size == 256); for (i = 0; i < 256; i++) { unsigned int val = (*red << 8) | *green | (*blue >> 8); df_set_video_palette_entry(i, val); } /* df_set_video_palette_entry automatically turns on * gamma for video - if this gets called, we assume that * RandR wants it set for graphics, so reverse cimarron */ dcfg = READ_VID32(DF_DISPLAY_CONFIG); dcfg &= ~DF_DCFG_GV_PAL_BYP; WRITE_VID32(DF_DISPLAY_CONFIG, dcfg); #endif } After re-make the Geode-driver, when I run the ‘fading’ option, the client program ( xscreensaver ) also print the debugging information about “fading…/ fading done”, now the screensaver is properly display. So through the test, I am sure that the main reason is upper function (lx_crtc_gamma_set). The ‘not display screensaver’ bug reason was found. I will follow it…. ** Changed in: xserver-xorg-video-geode (Ubuntu) Status: Incomplete => Confirmed -- Geode driver not display Screensaver https://bugs.launchpad.net/bugs/570584 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-geode in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
