Hi everyone.

I got a problem to access the Control-Center.....
I want to change my Screen resolution from 640x480 to something like 1240x1024.....

I go to the Controll-Center then Connected Devices -> Screen and Display Devices
and then a loading progress starts but nothing happens then...
i get no configuration GUI for Screen and Display Devices and after a while even the loading progress disapears from the taskbar

can someone help me ???

thank you very much

Press

Ctrl + Alt + the "+" on the number pad

That'll siwtch between 1024x768, 800x600, and 640x480

If you want 1280x1024 when booting from cd, use the cheatcode:

knoppix screen=1280x1024

Have you tried to edit the file /etc/X11/XF86Config-4 by hand you should see a section similar to this:


Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
# SubSection "Display"
# Depth 1
# EndSubSection
# SubSection "Display"
# Depth 4
# EndSubSection
# SubSection "Display"
# Depth 8
# EndSubSection
# SubSection "Display"
# Depth 15
# EndSubSection
# SubSection "Display"
# Depth 16
# EndSubSection
SubSection "Display"
Depth 24
Modes "1152x768" "1024x768" "800x600" "640x480"
# ViewPort 0 0
EndSubSection
EndSection


Xfree will you the highest resolution possible in the subsection Display as long as the card and monitor timings will support it the DefaultDepth setting is the one that will be used. In this example it would use the 1152x768 if supported. You should have you monitor correctly set in the Monitor section similar to this:


# Acer AcerView 54e
Section "Monitor"
#DisplaySize 270 200 # mm
Identifier "Monitor0"
VendorName "API"
ModelName "4536"
HorizSync 30-54
VertRefresh 50-120
Option "DPMS"
EndSection


You need the proper settings for the HorizSync and VertRefresh for your monitor to have the X system to get the best possible screen resolution. Before making any changes to the XF86Config-4 file you should back it up first so you have a known working copy you can go back to.
