Description kowalski marcin 2007-08-05 04:30:20 UTC

i had a problem stated in bug #9892. it was partly resolved, so i decided to open a new bug. 

i discovered that it boils down to the driver incorrectly detecting my display type.

i have an RV370 pci-e card (gigabyte x300se) with one dvi-i port and one s-video output.

05:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]
05:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]

the problem is - my LCD gives out into "no signal" when starting X with any version of xf86-video-ati driver a few git commits after 6.6.3 (specifically the "dynamically allocate connectors commit broke the driver for me, see bug #9892).

i have benq fp72g+d lcd display connected via dvi cable.

first test:


today's git
-------------------------
i specified Option "Monitor Layout" "TMDS,TMDS" in xorg.conf

X starts and works (judging by HDD activity) and i can kill it with ctrl+alt+bksp every time with no lockups.

look closely at lines 607-617 - it claims that my display is connected via VGA port, which my card does not even have!
-------------------------

6.6.3
-------------------------
http://pastebin.ca/646281

again, look at lines 586 - 596. see the difference? this time my display is identified on DVI-I conector (which is right).
-------------------------

without specifying the MonitorLayout option the logs look about the same.

i'll post them later if needed.

can you post a log with no monitorlayout specified?

I've no idea what your BIOS is actually saying...

Comment 2 kowalski marcin 2007-08-05 08:23:58 UTC

here you go

git driver : http://pastebin.ca/646422

6.6.3 : http://pastebin.ca/646424

xorg.conf used : http://pastebin.ca/646428

Comment 3 Alex Deucher 2007-08-06 06:57:15 UTC

can you get me a copy of your video bios (my email address is in the cc list)?

cd /sys/bus/pci/devices/<card_pci_id>
echo 1 > rom
cat rom /tmp/rom
echo 0 > rom

You can find the card's pci id by looking at the output of lspci.

Comment 4 kowalski marcin 2007-08-06 07:55:50 UTC

ok, sent

Comment 5 Dave Airlie 2007-08-23 01:49:14 UTC

you probably want to try this with randr-1.2, output routing screwedness in 6.7 is best solved in randr1.2, I'm removing the blocker.

please try with 6.7.191

Comment 6 kowalski marcin 2007-08-23 01:52:15 UTC

ok. i'll test it in a few (5) hours.

Comment 7 kowalski marcin 2007-08-23 08:54:05 UTC

it helped. i get out of sync message on my lcd for a split-second, and then the display shows up and (hopefully) everything works.

using git source. latest commit is b0f170c5f736ecba1a5899d602c4173fe9b9b1fa ( "radeon: Remove unnecessary #include <time.h>." ).

i'll do some more testing before closing the bug (e.g. cold boot etc.).

Comment 8 kowalski marcin 2007-08-23 11:50:12 UTC

okay, i think it's safe to close this one. no problems encountered so far.
