how do I set the default resolution? (slackware-current)

Drone4four · 08-10-2006, 05:19 AM

The default resolution on startup (when kdm loads) is 1152 x 900. I can't actually see the whole screen. I need to move the mouse around to view a different section. It's hard for me to explain. Anyways, only once I've logged into my window manager I can enter the command “xrandr -s 0” which then changes the resolution to 1024 x 768. I hate having to enter that xrandr command every singly time I log in. What command do I enter to permanently set the resolution to 1024 x 768?

edit: grammar

Edit your /etc/X11/xorg.conf so the 'largest' resolution is 1024x768. (The first one on the list would be your default)

It's the virtual desktop feature where the desktop size > screen size. You need to disable it. Run xorgconfig and manually reconfigure with the resolution of your choice and disable virtual desktop. Or alternatively, just edit your /etc/X11/xorg.conf

I removed all references to 1152x768 in my xorg.conf. For some reason, 1152x900 is still an xrandr option.

Code:

invert@314:~$ xrandr 
 SZ:    Pixels          Physical       Refresh
*0   1024 x 768    ( 390mm x 305mm )  *85  
 1    800 x 600    ( 390mm x 305mm )   85  
 2    640 x 480    ( 390mm x 305mm )   85  
 3   1152 x 900    ( 390mm x 305mm )   85  
Current rotation - normal
Current reflection - none
Rotations possible - normal 
Reflections possible - none
invert@314:~$

Here is the screen section of my xorg.conf:

Code:

# **********************************************************************
# Screen sections
# **********************************************************************
        
# Any number of screen sections may be present.  Each describes
# the configuration of a single screen.  A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.

Did you restart X after changing the file?
