I played around with gtf and found that my purportedly 1280x960 monitor can display higher resolutions quite nicely (no missing pixels, apparently). Here is a list of the resolutions and refresh rates I tested:
//These flicker pretty badly [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] //These are tolerable [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] //This has noticeable horizontal bars [EMAIL PROTECTED] Resolutions with refresh rates below 50 or so flickered noticeably while resolutions with heights smaller than 480 tended to have horizontal black bars. Other than that, I was able to choose just about any resolution I wanted, but I had to adjust the refresh rate for the image to appear and not fall over the screen. I would say the range of tolerability of these resolutions is probably 512x384...1600x1200. Here is a new RADEONeMacModes that includes these modes when the 'super' mode is set to nonzero and uses canonical values when 'super' is set to 0: static DisplayModePtr RADEONeMacModes(xf86OutputPtr output, int super) { ScrnInfoPtr pScrn = output->scrn; DisplayModePtr last=NULL, new=NULL, first=NULL; int i, *modep; int modecount = super ? 21 : 5; static const char *modenames[] = { "640x480", "800x600", "1024x768", "1152x864", "1280x960", "320x240", "512x384", "1280x1024", "1280x768", "1280x800", "1360x768", "1368x768", "1400x1050", "1400x900", "1600x1024", "1600x1200", "1792x1344", "1856x1392", "1920x1200", "1920x1440", "2048x1536" }; static int modes[] = { 62120, 640,680,752,864, 480,481,484,521, 76840, 800,848,936,1072, 600,601,604,640, 99070, 1024,1088,1200,1376, 768,769,772,809, 112360, 1152,1224,1352,1552, 864,865,868,905, 124540, 1280,1368,1504,1728, 960,961,964,1001, 32280, 320, 344, 376, 432, 240, 241, 244, 282, 49710, 512, 544, 600, 688, 384, 385, 388, 425, 123190, 1280, 1368, 1504, 1728, 1024, 1025, 1028, 1064, 128770, 1280, 1368, 1504, 1728, 768, 769, 772, 810, 128040, 1280, 1368, 1504, 1728, 800, 801, 804, 842, 137120, 1360, 1456, 1600, 1840, 768, 769, 772, 810, 137710, 1368, 1464, 1608, 1848, 768, 769, 772, 810, 138590, 1400, 1496, 1648, 1896, 1050, 1051, 1054, 1091, 139160, 1400, 1496, 1648, 1896, 900, 901, 904, 941, 156430, 1600, 1704, 1880, 2160, 1024, 1025, 1028, 1065, 155470, 1600, 1704, 1880, 2160, 1200, 1201, 1204, 1241, 174000, 1792, 1912, 2104, 2416, 1344, 1345, 1348, 1385, 178710, 1856, 1976, 2176, 2496, 1392, 1393, 1396, 1432, 186570, 1920, 2048, 2256, 2592, 1200, 1201, 1204, 1241, 184140, 1920, 2048, 2256, 2592, 1440, 1441, 1444, 1480, 195170, 2048, 2176, 2400, 2752, 1536, 1537, 1540, 1576 }; modep = modes; for (i=0; i<modecount; i++) { new = xnfcalloc(1, sizeof (DisplayModeRec)); if (new) { new->name = xnfalloc(strlen(modenames[i]) + 1); strcpy(new->name, modenames[i]); new->Clock = *modep++; new->HDisplay = *modep++; new->HSyncStart = *modep++; new->HSyncEnd = *modep++; new->HTotal = *modep++; new->VDisplay = *modep++; new->VSyncStart = *modep++; new->VSyncEnd = *modep++; new->VTotal = *modep++; new->Flags = 0; new->type = M_T_DRIVER; if (i==2) new->type |= M_T_PREFERRED; new->next = NULL; new->prev = last; if (last) last->next = new; last = new; if (!first) first = new; xf86DrvMsg(pScrn->scrnIndex, X_INFO, "Added eMac mode %s\n", modenames[i]); } } return first; } Of course, some of these resolutions require a raised Virtual setting. Also, the "default modes" that are added when Xorg starts sometimes conflict with these modes. For instance, a [EMAIL PROTECTED] mode overrides my [EMAIL PROTECTED] The former does not fit into the screen quite as nicely as mine. These extra modes (particularly the 1280x1024) would be neat to have available. You might consider making an emac-hack MacModel for them :) By the way, I saw somewhere on the internets that Apple may be releasing a new eMac at some point. I don't know if this rumor is true or not. It would have an LCD monitor instead of a CRT. So for Googlers out there: Old eMac CRT eMac eMac G4 Radeon driver won't work in Linux or Xorg Graphics won't work in Linux or Xorg Solution: Read this mailing list thread starting from the beginning :) _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
