--- Comment #3 from Ilia Mirkin <[email protected]> --- The interesting bits from the log: [ 128.852] (II) NV(0): I2C bus "DDC" initialized. [ 128.852] (II) NV(0): Probing for EDID on I2C bus A... [ 128.852] (II) NV(0): I2C device "DDC:ddc2" registered at address 0xA0. [ 128.855] (II) NV(0): ... none found [ 128.855] (II) NV(0): Probing for EDID on I2C bus B... [ 129.092] (II) NV(0): ... none found [ 129.092] (--) NV(0): CRTC 1 is currently programmed for DFP [ 129.092] (II) NV(0): Using DFP on CRTC 1 [ 129.092] (--) NV(0): Panel size is 1400 x 1050 [ 129.092] (II) NV(0): NOTE: This driver cannot reconfigure the BIOS-programmed size. [ 129.092] (II) NV(0): These dimensions will be used as the panel size for mode validation. [ 129.092] (II) NV(0): Panel is LVDS Note that the xf86-video-nv recognizes device id 112 (and a boatlod of others) as mobile, and for those it forces pNv->FlatPanel = 1, which in turn causes: if(pNv->FlatPanel) pNv->CRTCnumber = 1; if(pNv->FlatPanel && !pNv->Television) { pNv->fpWidth = pNv->PRAMDAC[0x0820/4] + 1; pNv->fpHeight = pNv->PRAMDAC[0x0800/4] + 1; pNv->fpVTotal = pNv->PRAMDAC[0x804/4] + 1; pNv->fpSyncs = pNv->PRAMDAC[0x0848/4] & 0x30000033; xf86DrvMsg(pScrn->scrnIndex, X_PROBED, "Panel size is %i x %i\n", pNv->fpWidth, pNv->fpHeight); xf86DrvMsg(pScrn->scrnIndex, X_INFO, "NOTE: This driver cannot " "reconfigure the BIOS-programmed size.\n"); xf86DrvMsg(pScrn->scrnIndex, X_INFO, "These dimensions will be used as " "the panel size for mode validation.\n"); } if(monitorA) xf86SetDDCproperties(pScrn, monitorA); if(!pNv->FlatPanel || (pScrn->depth != 24) || !pNv->twoHeads) pNv->FPDither = FALSE; pNv->LVDS = FALSE; if(pNv->FlatPanel && pNv->twoHeads) { pNv->PRAMDAC0[0x08B0/4] = 0x00010004; if(pNv->PRAMDAC0[0x08B4/4] & 1) pNv->LVDS = TRUE; xf86DrvMsg(pScrn->scrnIndex, X_INFO, "Panel is %s\n", pNv->LVDS ? "LVDS" : "TMDS"); } and later on if(pNv->FlatPanel == 1) { vertStart = vertTotal - 3; vertEnd = vertTotal - 2; vertBlankStart = vertStart; horizStart = horizTotal - 5; horizEnd = horizTotal - 2; horizBlankEnd = horizTotal + 4; if(pNv->Architecture == NV_ARCH_30) horizTotal += 2; } We should figure out what all this maps to in nouveau and how to properly fake it. -- You are receiving this mail because: You are the assignee for the bug.
