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?
The LG tries to be smart, but look at those numbers -- this is too far out of range.
Perhaps the ISOLINUX notice flashes by too quickly ... but as soon as the DVD boots the screen blanks.
A few notes:
- 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?
And then I carry the machine up from the basement and plug it in in the office with the 'production' setting, the LCD, and ... well, no, it won't see the EDID and settles for 800x600 and won't shift. I've tried editing the boot line, the grub/gfxboot and the xorg.conf to include 1024, 1280 with various modelines. NADA.
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?
No, I've tried 3 generations including one that won't go beyond 1024, and old Philips. I'll see if I can get a HP to try...
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.
LOL! Yes I know abut that. People were throwing out LGs by the cartload and some of us 'rescued' them and, as you say, applied 'hit iron'.
No, this LG is solid. As I say, it works just fine with Fedora 15 though 17.
As I said:
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.
My typo. I just crept round the back and the label says 1953TS. The manual I have says 1280x1024 http://www.lg.com/uk/monitors/lg-L1953S-lcd-monitor
When I look at the boot command line I see edd=off highres=off nomodeset nohz=off Now why did it put all that in there?
I just tried editing the command line as you suggested. No change.
