Black screen - wassup?


Hi,

Ok, those that know, know that I got F12 running. There is a snag. It runs on a Compaq P50, but not on an HP75. What I get is the boot splash (animated), a cursor left-top and the screen being turned off (light blinks) when the X is supposed to come on. I tried to login (blind) and that seems to work.

Any ideas?

Thanks.

Thor

Well, no.

Hi,

Thanks for a reply. The snag is that my system (HP/Compaq) DOES show X on a P50 but not on an HP75 (D8900)

The specs of the card:

and the log didn't seem to give any errors...see the attachment if you need to...

When I use the system on the HP75, I get the boot splash, then a black screen, though the system seems to be up and running (HD is active), but the light blinks, as if it did a power-save on the monitor...

Any in-sight would help, really

Thanks

Thor

We need the specs for the two boxes. The video chipsets may be different. I had a similar experience with my Debian box when the video card died. It defaulted back to the onboard video and would not run X system. I could just get cli prompts.

Not sure what is going on here.
No errors in your X.log, but a couple of warnings.

The xorg.conf I used:
You should not need to use an xorg.conf Modern Xorg versions configure everything pretty much automatically and you may find you do not even have an xorg.conf in a perfectly working system.

Is this the xorg.conf your F12 installation gave you, or did you make it yourself?

Ehrm...it is one box, the one box works with a Compaq P50 monitor, but not on an HP75 monitor...

Right now, it works bare-bones (no xorg.conf) on the P50 (15" - the size of a stamp, basically), I tried to get it to work on the HP75 (17" - bit bigger stamp) but both with and without xorg.conf failed on that one...

Hi,

Well, as I noticed that the system did not work with the 17", I made one using the info on this page

http://www.freebsd.org/doc/en_US.ISO.../x-config.html

And, yes, it didn't have an xorg.conf as it came "out of the box", as you pointed out. I was under the very same impression that X nowadays didn't even need one. So I hoped to give the system a (very gentle) nudge with an xorg.conf...

Hi,

Me again...I regenerated a new xorg.conf (since having no xiorg.conf does'nt work anyway) and tested it with

X -config xorg.conf.new

I got a black screen, but at least, the monitor kept being lit...

As I dropped back to the prompt (ctrl-alt-backspace) it complained that fbcon could'not be found, it is there, but not in the path...µ

newbie question: where do I set/append the path (script) for runlevel 5?

I thing I have to append the path with the path to this fbcon...

Tnx

Thor

Code:
PATH=$PATH:/path/to/add
export PATH
But fbcon is a module, not an executable the $PATH is meaningless in this context.

If you need fbcon, insert it (you need to be root) like this:

Code:
modprobe fbcon
Does the monitor work on another PC? Maybe one running a different OS?

Hi,

Yes, the monitor works, it is my main monitor. I still have F10, I installed F12 on another PC with another screen (the P50) in the hope to have it fully tweaked and installed before putting it in service - on the main (HP75) monitor...

Luckily I'm still up-and-running on the F10!

So, modprobe. Ok, I'll have to "freeze" that in a start up script, because using it in a console means that it will "disappear at reboot

Let me try it in a console...

I'll be back with an answer.

and...it says

FATAL module not found

I did an updatedb and then a locate, what I founs was a wakeup for the monitor, perhaps, because fbcon cannot be found, the monitor does not "wake up"...

So, looking for that module...

Thor
(they said Linux is an adventure, well, they were right )
Oh and, yes, I tried a yum install fbcon, but that came up empty...

I tried something, using this for an xorg.conf:

Quote:
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
I do get X to run, of course, it's only vesa...
