How to change screen res. at boot??
 

I just installed Fedora 3 Redhat linux on my laptop (ibm thinkpad a21p), however i think i set the resolution wrong during setup so when i boot for the first time the login screen is really messed up...
how do i change the resolution of it before it gets to it??

like the shell bootup part is fine..
just not the GUI part

Edit your /etc/X11/xorg.conf file (or XF86Config)

Subsection "Display"
Depth 8
Modes "800x600" <--- edit the modes to your resolution
ViewPort 0 0
EndSubsection

lemme try

ok.. how do i use vi to save and exit?

also i have to display sections... they have multiple modes for each one..

box@LinuxBox420~$vi /etc/X11/xorg.conf

to insert text.

to get out of text mode and back into a neutral mode.

if you need to delete something while in the neutral mode...

to save you file...

vi

ok.. but i have 2 display sections

Edit them both or the one that is set default...

Section "Screen"
Identifier "Screen 1"
Device "NVIDIA GeForce"
Monitor "My Monitor"
DefaultDepth 24 <---- see the defaut

Subsection "Display"
Depth 8
Modes "800x600"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 1
Modes "800x600"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24 <--- so i would edit this one
Modes "800x600"
ViewPort 0 0
EndSubsection
EndSection

well.. guess i'm reinstalling FC3..

fucked up the config file, i'll be posting in about half an hour

when you do goto 'custom settings' then LCD display then select 1024x768

and then ok

then in the menu it should still say 800x600 but click it and your higher display res will be there for you to choice

1024x768 I think is generic laptop display. Works great on my My IBM Thinkpad T22

and when your done take a look at your /etc/X11/xorg.conf file and see how it is setup after for future reference

You don't have to re-install! Delete your /etc/X11/xorg.conf and run...

to make a new config file...

Hope your read this in time!

that wont always work, I just tryed it on my fc3 system with command not found

too late.. i'm starting install again..
i'll need ur guys's help once its up and going again

well now that you are installing...........when in the preferences at the last part, where you set a standered user login name and passwd there is an option for screen resolution, and becouse most likly it didnt pickup a monitor type you will need to do what I said a few posts ago clicking the 'custom settings' or somthing like that above the resolution menu

HAHA, I've done quite a few re-installs, too! Makes it easier on yourself the next time you do a re-install; practice makes perfect.

ok... now the login screen doesn't even want to come on at all..
time to reinstall again!!
