I changed video settings & rebooted, now I cant change it back - black screen ??
 

HI

[redhatlinux9] I was playing around with my graphics card settings and now I have the black screen of death :jawa: I cant see anything because my monitors frequency is now out of range -

ie: boots up goes through the 'OK' check list.... and then localhost appears - then atoumaticaly takes me into what is the graphical login screen but the monitor cant handle it and therefore goes black...... arrrgh! :cry:

So bascialy I dont know how to change the settings back?

Can anyone help? :confused:

(the next step would be to take out the video card then hopefully it would detect a new one..?)

Thanks

Press Ctrl-Alt-F1 to get to a textual login screen, log in as root, drop to runlevel 3 (init 3) then edit the /etc/X11/XF86Config file (or whatever it's called). There may be a text config program I'm not sure, but editing the text file to get the frequencies back in range will do the trick. Then return to runlevel 5 (init 5)

login in single user .. then convert run level to --
init 3 by editing /etc/vi initrd
change screen resolution

Hi mike

Thanks for reply, I tried that and it doesnt seem to give me a textual login screen-

although it does affect my monitor in some way- instead of a dark black it changes it to a gray black
(at this point in time I dont blame you for thinking I am insane but unfortunalty thats what it does :D ) but I still cant see the command prompt?

another piece for the puzzle?

maybe i am pressing Ctrl-Alt-F1 to late?

At what point in the boot up can i press Ctrl-Alt-F1

Thanks

hey waynah

i have the exact same prob
and my monitor is displayin frequency out of range

pls pass on the solution if u stumble on it
wil do the same

:D

After a faulty "driver" change in the "/etc/X11/xorg.conf" file, I also got a blank "out of range" screen.

After a reboot, linux tried to start X, but showed the "out of range" message. tried again, got "out of range" and so on and so forth, until (after about 2 minutes) I got a message that X-server couldn't be started (duh...:)), and that linux will try to start X with a fresh config.
After that, it worked. (and even let me choose the "driver" to be used out of a list).

I'm using Fedora Core 6... it might be a rescue procedure that exists only on FC6?
I dunno...

Good luck!

The same thing hapened when I installed Slackware 11 to my brothers computer, his monitor couldn't handle the default settings, and I had already changed the default runlevel! I got around this by booting a live CD, any will probably do, but I used SLAX. From there I did xorgconfig, and copied the file saved to RAM over the Slackware 11 file, that worked for me.

I have this same problem and I cannot get to the login screen. It just goes completely black on the screen and does not say "out of range" or anything else. I really really like Linux and DO NOT want to give it up but I have had this happen 4 times over a 10 month span and every time I have to reinstall. I can not keep doing this.

1. This happens randomly. I do not alter my settings.

2. I dual boot Windows

3. I cannot get the login text screen.

4. I am using Fedora Core 5. (Will upgrade to 6 provided I can see my screen)

Any help would be greatly appreciated and if you need any additionally information post and I'll reply ASAP

Ok oddly.......I reset my BIOS jumper on MB and now I'm good to go. I guess I want to know why this happened now. I did not change any values in my BIOS.
