Hi, everybody,
I recently had a monitor blow out (turned it on one morning and got nothing but a white screen and white raster lines), and ever since I plugged in a different, working monitor, BFX2 appears to shut off the video after it loads.
My desktop is set for dual booting. I can boot up in Windows without a problem, and the BFX2 -r3 live CD also boots just fine.
But when I boot to BFX2 on my hard drive, I get the usual info--enabling DMA for drives, checking filesystems, setting system clock, setting up CUPS and so on--and then the screen goes blank.
I've tried editing the kernel line to add failsafe, screen=1280x1024 and fb1280x1024, but it seems to make no difference.
Is there some kind of switch that I can reset, maybe by getting in there via the live CD? I'd hate to lose all the programs I've painstakingly installed over the months.
Any help would be appreciated.
Thanks!

Try copying /etc/X11/xorg.conf over from the LiveCD to installed one.

Hi Kevin!
Well, it's rather obvious why that happens. The old monitor perhaps did 1280x1024@100Hz, while the "new" one only does 1280x1024@85Hz. If the monitor recieves the 100Hz (configured in xorg.conf) it shuts off to avoid getting fired.
You can either replace the xorg.conf with the one from the LiveCD, like alloydog suggested, or you can boot the LiveCD access the BFX2 partition and edit with the values of the new monitor (vertical (Hz) and horizontal (KHz) refresh rate).
I'd prefer the latter, because it is not sure, that the LiveCD will detect you monitor correctly. Especially the refresh rates are usually off a bit. The technical data of the monitor should be in the manual. Replacing xorg.conf would be the easier solution, though.

You can usually get the vert/horiz details for the monitor from the manufacters website, or if you have access to a Windows PC, look in monitors ini files - they contain the same information as xorg.conf.

Thanks, guys,
I'll try to get the vert/horiz stuff through Windows first, and swap in xorg.conf if I'm unsuccessful.
By the way, I actually tested 2 working monitors (both used) and got the same results, although one of them asked "Is PC setting correct?" before I heard the little click of a relay and the video shut off.

What is the monitor's make & model?

It's a Compaq Presario 1525 color monitor, Model 312A.
Haven't found the specs yet.
Correction: The monitor might be a Compaq CPQ1506. At least, that's how BFX2 identifies it. The above info was on the back of the monitor itself.

Update: I went to copy xorg.conf from the live CD to my installed BFX2, and when I booted up the live CD (revision4) the screen became very dim. Even with the brightness and contrast controls cranked all the way up, I could hardly see the icons, and the taskbar at the bottom was a dull white/gray. The cat was only visible in outline. This has not happened before with the live CD. If I boot to Windows on the same computer, the screen looks normal.
Do all these problems simply mean that the monitor is too old? (I'm saving for a new-to-me laptop, and that's why I didn't get a better monitor.)
Again, thanks in advance for the help.
Kevin

alloydog,
Oh, sure, go ahead and rub it in: my monitor is so old it's not even on the MonitorsDB list.
OK, I get it. I bought a 3-year old NEC monitor today. Just copied the xorg.conf file from the live CD to the HD install. Hope it works...

Newer monitor seems to have solved the problem. Thanks everyone!
I do have a persistent problem with horizontal shadows, though, by which I mean that if there's a dark object on the screen, everything to the left and right of it looks like it's shaded. I started having this problem a while ago, and even with the new monitor it's there.
Does anyone know what causes this?
Thanks again!
Kevin
PS alloydog, hope you didn't take offense. I was just joking.
PPS How can I add "SOLVED" to the topic line?

@PPS Just edit your first post's title.
