Everything is starting ok. but by the time it gets to the login screen my monitor is unreadable.

Do you manually type "startx" or does it automaticly start?

gregrh · 03-23-2005, 04:09 PM

No it starts automaticly.

Hmm...I'm not sure how you can stop it, but can you try booting it using a rescue cd, rescue floppy, or live-cd? If you use the live-cd, you can mount the hard drive and change the settings.

Can you find the settings for your monitor? Do you have the monitor docs?

I tried the rescue cd but I was booted into I think it's been two days since I work on this problem. (\sbin\???) and could not start the config pgm. and not knowing where it is I could not find it or that portion of the hard drive was not mounted. I don't have a live-cd or a rescue floppy. Where can I get either? and yes I do have the docs on the monitor.

Can you edit files on the computer using your rescue cd? If you can try editing the xorg.conf file in /etc/ (I can't remember where exactly it is but look around. It may be in a folder called X or something similar.

while booting, if you add "init 3" as a parameter it should start command line only. no gui. once in there, you can edit your xorg.conf file (vi /etc/X11/xorg.conf) and make the necessary changes.

hope that helps

You should still have access to a virtual terminal and the command line with <Ctrl>-<Alt>-F1 through F6, without having to reboot.

Questions:
1) Are you using the correct driver for your video hardware?
2) What distro and version are you using? Some are still using /etc/X11/XF86Config instead of xorg.conf for configuration.
3) You may need to edit the config file in question with new horizontal and vertical display settings based the model's specifications (should be in the instructions/manual/webpage).

I just found out that to terminate and Xserver you type <ctrl>+<alt>+<backspace>. You hold down control and alt and backspace. Then you should have the command line. Type

Code:

vi /etc/X11/xorg.conf

Now to edit text press "Insert" on your keyboard. Once you are done, press "Esc" and type ZZ (make sure it's in caps).
Use your monitors docs.

NOTE: That is the slackware 10.1 config file. Replace "xorg.conf" with the name of your config file.
To find it type

Code:

ls /etc/X11

and replace xorg.conf with the name of the x*.conf file, * being a wildcard.

Thank you all VERY VERY VERY Much. I tried (ctl-alt-backspace) and the (init 3) on boot options. Both worked GREAT.....

calcon · 03-24-2005, 02:27 PM

You're welcome. Hope everything works out for you
