When I run xrandr --off or --auto there is a quick flicker on the TV but that is all. This is with an HP Pavillion dx6000 computer and a 965GM video card.

Digging further, the problem seems to be triggered by i830_tv_detect_type(). In particular when TV_CTL is clobbered to enable detection mode. Patch below effectively stops this clobbering, but since I use Component output, I needed the second patch to for COMPONENT output with the detection disabled. diff --git a/src/i830_tv.c b/src/i830_tv.c index 6adb9f2..f442a4f 100644 --- a/src/i830_tv.c +++ b/src/i830_tv.c @@ -1297,7 +1297,7 @@ i830_tv_detect_type (xf86CrtcPtr crtc, DAC_A_0_7_V | DAC_B_0_7_V | DAC_C_0_7_V); - OUTREG(TV_CTL, tv_ctl); + //OUTREG(TV_CTL, tv_ctl); OUTREG(TV_DAC, tv_dac); i830WaitForVblank(pScrn); tv_dac = INREG(TV_DAC); @@ -1316,6 +1316,7 @@ i830_tv_detect_type (xf86CrtcPtr crtc, "Detected Composite TV connection\n"); } type = TV_TYPE_COMPOSITE; + type = TV_TYPE_COMPONENT; } else if ((tv_dac & (TVDAC_A_SENSE|TVDAC_B_SENSE)) == TVDAC_A_SENSE) { if (pI830->debug_modes) { xf86DrvMsg(pScrn->scrnIndex, X_INFO, Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/179797/comments/29 ------------------------------------------------------------------------ On 2008-05-17T11:10:28+00:00 Pcgomes wrote: I am facing the same bug. I have a Compaq C730 with a Intel 965GM card, running openSuse 10.3 x86-64. I've downloaded the Intel 2D driver source code and recompiled it commenting "OUTREG(TV_CTL, tv_ctl);" line, just like the patch does. Now I can switch on/off the S-Video output using xrandr --output TV --auto/off. Anyway it's not 100% yet, because when I turn the S-Video output on, the xrandr says that the TV output is disconnected, although the TV is showing my X session correctly. This is a big issue for me, because my TV system is PAL-M and if xrandr can't figure out the the TV is connected, it doesn't allow me to switch from NTSC to PAL-M with "xrandr --output TV --set TV_FORMAT PAL-M". Another issue is that, the TV Out is on and if I change the LVDS display, it turns the TV off.

If you continue to have issues when LVDS is changed, try also commenting out the line "if (intel_output->load_detect_temp)", to make the detection logic unconditional.

I have applied the patch you've told me, but then I get the same error:no Tv output, and just a brief blink when I type "xrandr --output TV --auto". I've attached some log files, in case they would be helpful. I can generate more of those, at different scenarios, if anyone asks for it. Any help would be great.

Unfortunately none worked for me and the problem persists. Also, there is one extra issue: randr displays that TV is disconnected after I send "xrandr --output TV --auto", although the cable is connected and the TV On. I've copied the xrand output and I will comment the behaviour of the TV, if this is somehow useful.

Sorry for the confusion. Did you reboot after installing the patched driver? I found that once TV output got into the bad state (ie from the unpatched driver), I could not get it to work again until I rebooted. -Rob Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/179797/comments/37 ------------------------------------------------------------------------ On 2008-05-22T11:09:09+00:00 Pcgomes wrote: (In reply to comment #23) OK, now the this patch works partially for me (I didn't reboot last time).

I suspect the additional detection issue you are seeing is a separate problem. As a workaround until it is fixed you might want to try selecting PAL-M in xorg.conf at startup rather than via xrandr. Something like the following snippet should be sufficient Section "Device" Identifier "Generic Video Card" Driver "intel" BusID "PCI:0:2:0" Option "monitor-TV" "TV" EndSection Section "Monitor" Identifier "TV" Option "TV Format" "PAL-M" EndSection Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/179797/comments/40 ------------------------------------------------------------------------ On 2008-06-05T07:32:56+00:00 Sirrichard wrote: I believe that this bug is related to an earlier bug that I filed (#13743) which is still unresolved.

Richard, The correct fix that works for me very reliably for week is in comment #21 above. The patch that commented out the "OUTREG(TV_CTL, tv_ctl);" was just a hack while I was chasing down the real bug. I've not seen the issue #13743 you reported as I don't ever swith VTs (I'm using these boxes as mythfrontends.

I also added a "i830WaitForVblank(pScrn);" function call at the end of the i830_tv_restore() and i830_tv_mode_set() functions, and this change fixed the issue when switching between text and X VTs. I tested by switching between text and X virtual terminals 20 times, and the graphical display came up all 20 times.
