Question Whose on first? DVI or VGA output...?!?! SUSE 10.2 shoots itself in the foot!!!


Hey there,

Well, I am sure you pros know but not trivial for the unannoited.

System has two PCIX video cards (Setup on mobo as SLI pair but not important to this issue. Only the main card is used during regular install). The main card has a DVI and VGA output. It would appear that the installs process defaults to the DVI out as display one and the VGA out as Display two (For whatever reason is seems to be able to show either during the install but makes a choice without asking during the install. There does not appear to be a choice like there use to be in the SUSE installs). Thus when the system boots up, the Display 1 (DVI out with nothing connected) is prime and probably has the booted system showing on it and Display 2 (VGA out with my monitor connected) is a blank screen (DOH!).
I have not found it trivial to get one of the screens turned off and/or the display 2 to be the primary. I can get the system to boot us to init 4 level and login, but running SAX2 is to no avail (it get lost and you get and ineffective screen after the second pass during initialization of SAX2 which says "Display 2. Configuration on Display 1." I ran into a similar problem once when upgrading the Nvidia drivers in SUSE 10.1, but I managed to someout get to a GUI and run the Nvidia configuration utility and turnoff the initial display and only use the one I had gotten to the Xserver desktop using that day. YAST runs but is not able to get to the point where one can fix the display 1 - Display 2 issue. I am not completely command line unfriendly and I a fairly sure the solution lies in the xorg.conf file for getting updated to the latest Nvidia driver and using their desktop tool to turn off the unwanted display. I saw some posts with listings about inserting "Ignore DFP1 display" or such. The SUSE folks seem to be shooting themselves in the foot not leaving that choice as an install option, especially for someone the first time into Linux which would drive them away instantly...

Best regards,

Lee Nelson

Have you looked in /etc/X11/xorg.conf

It appears that the suse installer is trying to autodetect where you have an active monitor, and for some reason the nv driver believed you had an active monitor on the DVI port.

The autodetection route is a concession to novices who are easily confused by multi-choice. Very good if it works - but when it dosn't...

Hey there,

Thanks for your observation. I am not sure if that is correct.

I do not have a device connected to the DVI connector nor hava I had at any time with this system. I noticed that this was an artifact that has been part of the install of this specific system with most SUSE distros.The ASUS EN6600GT board has two outputs, one DVI and one VGA. This of course allows for two monitors, implemented if you have the correct adapter(s). The SUSE distros prior to 10.2 still came to the correct conclusion that I had a standard CRT connected to the VGA connector. With SUSE 10.2, not such decision is forthcoming. The artifact appears during the monitor configuration process when an extra "X" appears on the screen when you do make any changes in the detected settings on the appropriate screen or at the end of the installation process. With the a CRT connected, the system has still booted to the desktop on the installed monitor. This became an issue in SUSE 10.1 when I moved to the Nvidia drivers by adding the Novell site as part of the Installation source or installed the latest drivers. I was able to use the Nvidia utility to tell the system there was only one display and it was display 1, had nothing connected and the system booted the same as this issue. CRT connected to display 2 but display 2 displaying zilch. (if I am not mistaken display one was called DFP1 or such). The Nvidia utility allowed me to remove that and chose the one with the monitor I was using at that instant.

None of the above is germaine as my goal is to arrive at a solution that is viable and implementable. Booting to a lesser OS level and running SAX2 is not an option (or does not appear to be as I have not arrived at a set of command line switches that will allow it to run correctly with the current setup of display 1 with no Flat Panel connected and display 2 with a CRT connected. I am fairly sure it cannot tell the which is which presently. I suppose I could implement a DVI to CRT adapter and connect my CRT to that and then fix the Xorg.conf file so the system's X windows system work until I can fing the proper tool to modify that same file for me.

Nasty old Microsoft Windows has no such problem but then they are so vile what difference does it make that they know what they are doing.

Anyway, I found a solution but not the answer to this question ( say what?!? ).
I went back through the install. Where you can choose screen size, ratio, number of colors, etc. one of the choices is 640x480 VGA. This is the one setting that dafaults the VGA output of the video card as display one. All other display resolutions default to the DVI output.

And there you go ...
Of course, you could report this to the SUSE team.
Install another release and "upgrade".
Install another release and wait for yet another release
Install a different OS - there are linuxes other than OpenSUSE...

Boot from a rescue disk and use that to edit your xorg.conf so it will work with SUSE... and so on and on and on.

However - I havn't found any mention of this trouble with your card and suse anywhere, suggesting this is not a generic problem.

There are lots of people reporting trouble with SUSE and this motherboard - however it is usually sound or SATA controllers.

But, never mind, so long as you have a useable setup now.

Thanks for the response bro. You know after all that I took off 10.2 and put back on the copy of 10.1 I purchase that comes in the green box with the lizard on the front. Yes, I am one of the guys who does buy software to benefit the cause. I rode the 10.1 build effort at opensuse.org and after burning so many CD's and doing so man network installs...I decided what the heck. So I purchase the the commercial copy from Novell. Good investment I feel. I should not have had so much trouble but I had to set away the distro for a few months and my skill dropped like a stone. I will get up to speed on the Xorg.conf file and the ins and outs of Sax2 so I do not have to wallow around..DOH!

The EN6600GT's are the video cards. They were some the first PCIX boards out after the run of the Nvidia 6800 GT's and Ultras in the AGP8x form. I got a couple of the TOP version of the EN6600GT to use in SLI mode..very well made. They look like they have never been run and they are 18 months old. I don't think I mentioned the mobo. It is an ASUS board also (AN8-SLI Deluxe...it is one of the earlier NForce 4 boards supporting SLI and AMD Athlon 64 939 form factor with same 939 socket...about 2 years old now but still very functional and still being sold) but the mobo I do not believe is the issue. I was as I mentioned able to force the choice of the VGA socket as Display 1 of the video card by selecting 640x480VGA resolution so that made it clear the DVI socket was being selected as Display 1 if any other resolution was chosen. I am pretty sure I could have connected a Flat Panel display with DVI connector to the port or used a DVI to VGA adapter and connected a CRT type monitor and had good display and resolved it that way. Why the default to DVI...I am not sure why....

Best regards,

Lee Nelson
