Hi,

I've just installed Debian 4 on my desktop PC with a ASUS EN7600GS (NVidia) graphical card and a 21" monitor.

The maximum screen resolution by default is 1280x1024 with a refresh rate of 60Hz.

Now I want to increase the screen resolution to 1600x1200 because the 7600GS is capable to handle this higher screen resolution.

I've modified the /etc/X11/xorg.conf file with:

Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation G70 [GeForce 7600 GS]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1600x1200" "1280x1024" "1152x921" "1152x900" "1024x768" "960x720" "832x624" "800x600" "720x400" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1600x1200" "1280x1024" "1152x921" "1152x900" "1024x768" "960x720" "832x624" "800x600" "720x400" "640x480"
EndSubSection
SubSection "Display"

Modes "1600x1200" "1280x1024" "1152x921" "1152x900" "1024x768" "960x720" "832x624" "800x600" "720x400" "640x480"
EndSubSection

EndSubSection

EndSubSection
EndSection

When I reboot, I still cannot switch to the 1600x1200 screen resolution. The highest screen resolution is still 1280x1024.

debian:/etc/X11# uname -a
Linux debian 2.6.18-4-686 #1 SMP Wed May 9 23:03:12 UTC 2007 i686 GNU/Linux


What do I missing here?

Thanks if you known the answer.

Try reconfiguring X:

Run "nvidia-settings" to see if that resolution is actually available to you.

When I run nvidia-settings, I got a window with on the left frame a text: "nvidia-settings Configuration" and nothing more.
On the right frame I got some toggle buttons with:
- Enable ToolTips
- Display Status Bar
- Slider Text Entries
- Include X Display Names in the Config File
- Show "Really Quit?" Dialog
and a Help and Quit button.

Is this normal?

No, that's not right. There should be a number of selections above the "nvidia-settings Configuration" selection.

Look at your Monitor section in the xorg.conf the refresh rates are usually set too low to allow higher resolutions, so find the settings for your monitor to put in there then once logged out of your display manager at the login screen use the CTRL + ATL + Backspace keys at the same time to kill off then respawn the X server with the new settings used. An example below of a configured section with the proper numbers used.

Hi,

Changing the Horizontal Synchronization and the Vertical Refresh Rate are the solution to be able to increase the screen resolution.

My settings in the /etc/X11/xorg.conf file are now:

# Sun GDM-20E20
Section "Monitor"
DisplaySize 406 305 # mm
Identifier "Monitor1"
VendorName "Sun"
ModelName "GDM-20E20"
HorizSync 28-80 # 30-115 # DDC-probed
VertRefresh 43-75 # 50-160 # DDC-probed
#Option "UseDisplayDevice" "CRT-1"
#Option "DPMS" "true"
#Option "BackingStore" "On"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation G70 [GeForce 7600 GS]"
Monitor "Monitor1"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1600x1200" "1280x1024" "1152x921" "1152x900" "1024x768" "960x720" "832x624" "800x600" "720x400" "640x480"
EndSubSection
...
EndSection

This works now and can increase the screen resolution to 1600x1200.
Thanks for your valuable hint!
