http://bugs.freedesktop.org/show_bug.cgi?id=15478 --- Comment #1 from Egbert Eich 2008-04-14 09:09:13 PST --- Old subject: "Detection Problems with Latest Git (2008-04-11)" The LCD doesn't give real DDC info on the LCD: (II) RADEONHD(0): Connector[1] {RHD_CONNECTOR_PANEL, "LVDS LCD1", DDC_NONE, RHD_HPD_NONE, { RHD_OUTPUT_LVTMA, RHD_OUTPUT_NONE } } The VESA BIOS often doesn't obtain DDC data thru I2C. Instead it's faked inside the BIOS. AtomBIOS may also contain a 'faked' DDC block and we try to retrieve it. In your case this fails: (II) RADEONHD(0): Query for AtomBIOS Get Panel EDID: failed If you can provide a copy of your BIOS (which you can dump with 'rhd_conntest -d' Looking at your connector table it shows 3 digital connectors: PANEL, DVI and HDMI. This shouldn't be possible with this hardware. The latter one doesn't seem to have any outputs. This could be the reason why it doesn't show in xrandr. The black screen problem in 3 is under investigation.

Also, if I unplug the VGA connection without first disabling it with xrandr, xrandr starts displaying bogus DVI-D_1 information (even if nothing has ever been plugged into the HDMI connection) until I re-plugin the VGA connection or run "xrandr --output VGA_1 --off" (which still goes through okay even after the VGA connection unplugged):

Could you specify what is printed before you unplugged anything? - If xrandr is ran before plugging in the VGA connector, the display always shows a miore pattern in the colours. This persists until Xorg is restarted and the display is plugged in before running xrandr. I don't really understand this: Where do you see this displayed? On the panel or on the VGA? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

http://bugs.freedesktop.org/show_bug.cgi?id=15478 --- Comment #5 from Tyson Whitehead 2008-05-18 10:13:41 PST --- I just tried the latest git (2008-05-18 up to and including commit starting with 2ea7cdd7), and the following issues have all now been resolved: 1- Ones that were present only if an external monitor was plugged into the VGA port before and when XOrg was starting up: a) I used to loose my ability to switch to a virtual terminal (ctrl+alt+F1 would just give a blank screen). b) The latop display used to remain dark on any subsequent restarts of Xorg (without rebooting the latop) unless the external monitor was re-plugged into the VGA port before the restart. 2- The colours on a monitor plugged into the VGA port used to sometimes look like they had all been randomly mapped around unless the display was plugged into the VGA port before and when XOrg was started (note -- this didn't always happen, so it still might not be fixed, but I believe it is as I haven't seen this once since upgrading). Still remaining is: 1- If I unplug an external monitor from the VGA port without first disabling it with xrandr, it then begans to report bogus DVI information: Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 1920 x 1920 VGA_1 disconnected 1920x1200+0+0 519mm x 324mm PANEL connected 1680x1050+0+0 444mm x 277mm 1680x1050 60.1*+ DVI-D_1 disconnected 1920x1200 (0x46) 154.0MHz h: width 1920 start 1968 end 2000 total 2080 skew 0 clock 74.0KHz v: height 1200 start 1203 end 1209 total 1235 clock 60.0Hz I can then get rid of by running 'xrandr --output VGA_1 --off': Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1920 x 1920 VGA_1 disconnected PANEL connected 1680x1050+0+0 444mm x 277mm 1680x1050 60.1*+ DVI-D_1 disconnected 2- The VESA driver reports EDID information for the laptop display, however, the radeonhd driver is unable to obtain it. I've attached a new xorg log file showing this again. 3- If I plug an external monitor into the HDMI port (through a HDMI -> DVI cable), either before or after starting Xorg, nothing happens on the computer end (xrandr report nothing and nothing shows up in the Xorg logs). I've repeated the rhd_conntest thing: a) With no external monitors plugged in to any of the ports: rhd_conntest: v1.2.1, git branch master, commit 2ea7cdd7 + changes Checking connectors on 0x9581, 0x103C, 0x30DF (@01:00:00): Load Detection: RHD_OUTPUT_NONE HotPlug: RHD_HPD_NONE DDC: RHD_DDC_NONE b) With only an external monitor plugged into the VGA port: rhd_conntest: v1.2.1, git branch master, commit 2ea7cdd7 + changes Checking connectors on 0x9581, 0x103C, 0x30DF (@01:00:00): Load Detection: RHD_OUTPUT_DACA HotPlug: RHD_HPD_NONE DDC: RHD_DDC_0 c) With only an external monitor plugged into the HDMI port (HDMI -> DVI cable): rhd_conntest: v1.2.1, git branch master, commit 2ea7cdd7 + changes Checking connectors on 0x9581, 0x103C, 0x30DF (@01:00:00): Load Detection: RHD_OUTPUT_NONE HotPlug: RHD_HPD_1 DDC: RHD_DDC_1 Thanks again to you guys for all their hard work on this!

Still remaining is:

1- If I unplug an external monitor from the VGA port without first disabling it with xrandr, it then begans to report bogus DVI information:

This sounds extremely weird. OTOH, this *could* be a side effect of a bug Luc fixed yesterday in the RandR code. Could you please try again with git head?

2- The VESA driver reports EDID information for the laptop display, however, the radeonhd driver is unable to obtain it. I've attached a new xorg log file showing this again.

We have this with multiple laptops. Egbert, would it be an option to the vesa EDID emulation if we don't get any information from AtomBIOS?

3- If I plug an external monitor into the HDMI port (through a HDMI -> DVI cable), either before or after starting Xorg, nothing happens on the computer end (xrandr report nothing and nothing shows up in the Xorg logs). I've repeated the rhd_conntest thing:

Atombios provides us information about a HDMI connector, but nothing about the used outputs: (II) RADEONHD(0): Connector[3] {RHD_CONNECTOR_DVI_SINGLE, "HDMI_TYPE_A DFP1", RHD_DDC_1, RHD_HPD_1, { RHD_OUTPUT_NONE, RHD_OUTPUT_NONE } } Egbert, does this sound like parsing error, or like broken connector table?

c) With only an external monitor plugged into the HDMI port (HDMI -> DVI cable):

rhd_conntest: v1.2.1, git branch master, commit 2ea7cdd7 + changes Checking connectors on 0x9581, 0x103C, 0x30DF (@01:00:00): Load Detection: RHD_OUTPUT_NONE HotPlug: RHD_HPD_1 DDC: RHD_DDC_1

So the DDC and hotplug information in the table is ok...

How do we know which EDID the VESA BIOS will report? Is it always the EDID of the panel? I would like to avoid going down this route. It's possible that the routine collecting the EDID data out of AtomBIOS still has problems. All the laptops I've access to (which would be my HP) obtain the panel EDID directly from the panel using DDC. On those there is no EDID block in AtomBIOS. I have no access to our other laptops. Let's Luc look into this. In any case we should have a mode line for the panel. Therefore this information is only needed to calculate the DPI. I'm not sure if we want to call the VESA BIOS when we already call AtomBIOS just to obtain EDID data to calculate the screen resolution.

3- If I plug an external monitor into the HDMI port (through a HDMI -> DVI cable), either before or after starting Xorg, nothing happens on the computer end (xrandr report nothing and nothing shows up in the Xorg logs). I've repeated the rhd_conntest thing:

Atombios provides us information about a HDMI connector, but nothing about the used outputs: (II) RADEONHD(0): Connector[3] {RHD_CONNECTOR_DVI_SINGLE, "HDMI_TYPE_A DFP1", RHD_DDC_1, RHD_HPD_1, { RHD_OUTPUT_NONE, RHD_OUTPUT_NONE } }

Egbert, does this sound like parsing error, or like broken connector table?

{RHD_CONNECTOR_DVI_SINGLE, "HDMI_TYPE_A DFP1", RHD_DDC_1, RHD_HPD_1, { RHD_OUTPUT_NONE, RHD_OUTPUT_NONE } } This information seems to be correct. We've got 3 digital outputs: PANEL, DVI and HDMI. These don't match nicely on the 2 digital blocks. Now the TMDSA and the LVTMA are used for dual link. So it's not possible to split any of those. Therefore there are 2 options left: 1. The BIOS has an option to select between the DVI and the HDMI port. 2. There is a DVO chip on the system. I would be able to tell if I had the BIOS. Tyson, please run rhd_conntest -d to dump the BIOS and send it to me in an email (eich_at_suse_dot_de).

No, as this exactly what's in the connector table.

Okay. I tried the latest git again (2008-05-22 up to and including the commit beginning with 566ba690), and it did not resolve this issue. I did, however, discover some additional information while playing around, and that is the bogus information also disappears if I plug the display back into the VGA connector. 1) Unplug the display from the VGA port after having activated it and without first deactivating it: Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 1920 x 1920 VGA_1 disconnected 1920x1200+0+0 519mm x 324mm PANEL connected 1680x1050 60.1 + DVI-D_1 disconnected 1920x1200 (0x46) 154.0MHz h: width 1920 start 1968 end 2000 total 2080 skew 0 clock 74.0KHz v: height 1200 start 1203 end 1209 total 1235 clock 60.0Hz 2) Plug the display back into the VGA port without doing anything via xrandr: Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 1920 x 1920 VGA_1 connected 1920x1200+0+0 519mm x 324mm 1920x1200 60.0*+ 59.9 ... <cut> ...
