See the man page for chkconfig, example;

chkconfig --levels 345 kudzu off
chkconfig --levels 345 kudzu on

Try removing the rhgb portion from the kernel line in /boot/grub/grub.conf for the blank screen problem. When the grub bootsplash screen is displayed press any key. Highlight the Linux boot choice and press the 'e' key. Highlight the line that begins with something like 'kernel /vmlinuz' and press the 'e' key, delete the 'rhgb' portion and one space. When done press the 'Enter key' followed by the 'b' key.
If this one time change works make it permeant, rpm -e rhgb

hi Lenard, check with you that you say See the man page for chkconfig? under this forum or in my terminal?

I want to disable the service nVidia-glx (for the time been)

the reason is every time I bootup need to press "i" for interact... (what ever that call) then the splash screen will show the text for detect what I got. so when the Service nVidia glx appear i need to press "N" then the rest i press c then it will contuine by itself then to the login screen (normal)

So which / how I need to do for the setting?

I (root)
type:

Code:

chkconfig --help
chkconfig version 1.3.29 - Copyright (C) 1997-2000 Red Hat, Inc.
This may be freely redistributed under the terms of the GNU Public License.

usage:   chkconfig --list [name]
         chkconfig --add <name>
         chkconfig --del <name>
         chkconfig [--level <levels>] <name> <on|off|reset|resetprioritie

so what should I need to set or type for chkconfig

and as you say level 345 what that mean for ?

now I have list the nvidia-glx

Code:

chkconfig --list nvidia-glx
nvidia-glx      0:off   1:off   2:on    3:on    4:on    5:on    6:off

so am I going to type (root):

Code:

chkconfig --levels 2345 nvidia-glx off

then as you write below:

Try removing the rhgb portion from the kernel line in /boot/grub/grub.conf for the blank screen problem. When the grub bootsplash screen is displayed press any key. Highlight the Linux boot choice and press the 'e' key. Highlight the line that begins with something like 'kernel /vmlinuz' and press the 'e' key, delete the 'rhgb' portion and one space. When done press the 'Enter key' followed by the 'b' key.
If this one time change works make it permeant, rpm -e rhgb

how to I going do that, could you show me out (me still new for FC also i'm

)

FireGunz · 03-30-2006, 09:18 AM

ok, i think should be this way (please see where I'm done the correct way)

type:

Code:

chkconfig --levels 345 nvidia-glx off

type:

Code:

service nvidia-glx stop

then as for -> Try removing the rhgb portion from the kernel line in /boot/grub/grub.conf for the blank screen problem.

you mean edit or delete the grub.conf file (if edit, how using which program to open it OR if delete, how to delete the file?

Gethyn · 03-30-2006, 09:43 AM

Don't delete your grub.conf file! That would be a really bad idea. You want to edit it, using whichever text editor you prefer (though you will need to be root to do so). You will have a line that looks something like this:

Code:

kernel /vmlinuz-2.6.12-10-686-smp root=/dev/sda8 rhgb

You need to change it to something like this:

Code:

kernel /vmlinuz-2.6.12-10-686-smp root=/dev/sda8

In other words, all you need to do is remove the rhgb kernel option. Note that your grub.conf will not look exactly as shown above, but similar - you need to find the line(s) beginning "kernel".

FireGunz · 03-30-2006, 09:46 AM

ok, i got the link for that -> http://www.linuxquestions.org/questi...hreadid=188870

type:

Code:

service nvidia-glx stop

also will do.... thank to Lenard help. thank you.

now does anyone got any idea how to got back the loading splash screen (which you able to switch to show/hide the detail) which after the grub bootsplash screen.

Lenard · 03-30-2006, 03:17 PM

Just add the rhgb postion back the same way you removed it.

Change it from somthing like this;

kernel /vmlinuz-2.6.12-10-686-smp root=/dev/sda8

Back to something like this;

kernel /vmlinuz-2.6.12-10-686-smp root=/dev/sda8 rhgb

FireGunz · 03-30-2006, 06:01 PM

hi Lenard,

I did check it, I still got/have the rhgb at grub.conf ?

but there is no loading screen for me.

any idea? the only thing I did turn off the nvidia glx yesterday. then the loading screen is missing.....

FireGunz · 03-30-2006, 06:15 PM

i even turn on the Service nVidia-glx also never get back the loading screen...

type:

Code:

chkconfig --levels 345 nvidia-glx on

type:

Code:

service nvidia-glx start

now i had disable the Service nVidia-glx and also check it I got the "rhgb" at grub.conf

here is my grub.conf at below:

kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVo100 rhgb quiet

and still missing the loading screen (interactive)...
