One of the problems I'm having is that the 12.2 DVD seems to do odd EDID behaviour. When I boot from the 12.2 DVD I get
Analog Out of range 46.4kHz / 43 Hz
Yes, I know there should be a "F3" for screen size. I don't even see that. This out of range is immediate.
Meaning what, screen goes black as soon as POST messages finish? Or does it happen when the first anything from booting the DVD should be drawing?
As soon as the POST finishes ... well as soon as the DVD boots. I never see anything past the POST; except the "out of range" notice on the monitor. I don't see the welcome screen, I don't see the screen offering F1, F2, F3 and the menu of install/boot from hard dis and whatever else.
Did you try the auto-adjust function while it displayed the out of range message?
Perhaps the ISOLINUX notice flashes by too quickly ... but as soon as the DVD boots the screen blanks.
A few notes:
- It happens with *All* my LCD screens.
More than one I don't recall you mentioning previously, not that my recall is anything to be proud of. :-p
- If I dig out an old CRT from my closet and plug that in, then I
see the boot screen and can work with the install.
Since you can, does it really matter if the 12.2 DVD doesn't like your display?
Its a crappy old 15" that buzzes ..
So it buzzes an hour or two until you finish installing. Is that a real problem?
- If I try installing an old version of openSuse, 11.2 or 11.4
for example, I don't have this problem with the LCD screens.
So what is it with the ISOLINUX on the 12.2 DVD? Is it booting from a late model - grub2 - version of ISOLINUX or something?
Pretty sure only ISOLINUX on DVD boot. But, the installation kernel makes it go, and KMS could well be the culprit if it is a KMS kernel.
Any ideas, guys?
Assuming DVD is OK, could be some bug in the installation kernel's KMS function that only shows up with your display's particular EDID. Did you md5sum the iso and the burned DVD?
Yes, the MD5 is OK.
As I say, its specific to LCDs
Oh, so you tried more than one LCD, and all you tried are LG195x models?
Do you have another cable you could try, especially one with EDID function inoperable due to a missing pin?
Same cable, same card/machine with Fedora and Mageia works.
The point was to see if a different video card or cable changes anything. Now that we know you have a garage full of LG LCDs it probably doesn't matter. :-)
http://www.badcaps.net/forum/showthread.php?t=15217 implies you may have tried those longer than a short time ago. What you could be experiencing is what http://en.wikipedia.org/wiki/Capacitor_plague describes. ISTR out of range might have been what clued me that my ViewSonic was exhibiting that problem, since solved in about 30 minutes with a soldering iron and less than $3 in parts already on hand.
I can set them nosplash and watch the messages and see the 'jump' when they see EDID and change resolution.
Can that PC already boot something else from Grub? If it can, load the installation kernel and initrd with Grub instead of starting from the DVD, from which you can use vga=791 and/or video=1366x768@60
Ah, this LG1952 only goes to 1280x1024@60.
In http://lists.opensuse.org/opensuse/2013-01/msg00026.html you wrote LG1953. Offlist you wrote LG1953S after which Google found me http://www.digi.co.id/lcd-lg-1953s.html that told me what you have is 1366x768. LG1952 is indeed 1280x1024, so if 1952 is in fact what you have, put video=1280x1024@60 on cmdline and see what happens, even if it means you must first boot Knoppix, install Grub, and put the installation kernel and initrd on it so you can initiate installation without a DVD.
And I'm not sure what you're asking/how to do that.
I didn't know whether or not you were trying to install to an empty HD.
This is an INSTALL. Unless I'm using another distribution .. Think of it as a blank disk.
OK, but that needn't stop you from installing without using a DVD that doesn't work as expected. I rarely install from OM, and almost as infrequently even download an iso.
