Re: I need a little Xorg.conf training Please

Yeah, that'd fix it.

Anyway, the best way to redo your xorg.conf is to just execute "sudo dpkg-reconfigure xserver-xorg", because you don't really want to much around with hardware settings unless you REALLY know what you're doing. This way, your hardware is detected and probed and stuff.

Oh, and could you do something about that long line? It's stretching the page...

Re: I need a little Xorg.conf training Please

You could also try changing the following:

Section "Screen"
Identifier "Default Screen"
Device "NVIDIA Corporation NV28 [GeForce4 Ti 4200 AGP 8x]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024@75" "1280x960@60" "1280x854" "1280x960@85" "1152x768@54" "1280x1024@85" "1152x864@75" "1280x1024@60"
"1024x768@43" "1280x960@75" "1024x768@60" "1400x1050@60" "1024x768@70" "1400x1050@75" "1024x768@75" "1600x1200@65"
"1024x768@85" "1600x1200@60" "832x624@75" "1600x1200@75" "800x600@60" "1600x1200@70" "800x600@85" "1600x1200@85"
"800x600@75" "1792x1344@75" "800x600@72" "1792x1344@60" "800x600@56" "1856x1392@60" "640x480@85" "1856x1392@75"
"640x480@75" "1920x1440@60" "640x480@72" "1920x1440@75" "640x480@60" "2048x1536@60" "2048x1536@75"
EndSubSection
EndSection

If you look at the section entitled 'Modes', you'll notice the resolution "1280x1024@75" is located first in the line; try placing the
resolution "1920x1200@60" just before "1280x1024@75". The configuration file seems to use the first resolution listed here as
the default resolution for your pc; I've just had a fiasco configuring my xorg.conf file, that's how I learned this tip. After reconfiguration,
it should look something like:

Section "Screen"
Identifier "Default Screen"
Device "NVIDIA Corporation NV28 [GeForce4 Ti 4200 AGP 8x]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1920x1200@60" "1280x1024@75" "1280x960@60" "1280x854" "1280x960@85" "1152x768@54" "1280x1024@85" "1152x864@75" "1280x1024@60"
"1024x768@43" "1280x960@75" "1024x768@60" "1400x1050@60" "1024x768@70" "1400x1050@75" "1024x768@75" "1600x1200@65" "1024x768@85"
"1600x1200@60" "832x624@75" "1600x1200@75" "800x600@60" "1600x1200@70" "800x600@85" "1600x1200@85" "800x600@75" "1792x1344@75"
"800x600@72" "1792x1344@60" "800x600@56" "1856x1392@60" "640x480@85" "1856x1392@75" "640x480@75" "1920x1440@60" "640x480@72"
"1920x1440@75" "640x480@60" "2048x1536@60" "2048x1536@75"
EndSubSection
EndSection

If you would like to, try the above and see what it does, remembering to restart the xserver after you configure the file. You can't really do anything irreplaceable
as long as you have a backup copy of the xorg.conf, and this shouldn't harm your computer anyway.

Re: I need a little Xorg.conf training Please

Thanks Integr8e;

How exactly do I restart X ? Can I simply open a terminal window and enter:

sudo startx

Please advise.

Re: I need a little Xorg.conf training Please

Just startx will do it.

Re: I need a little Xorg.conf training Please

Or Ctrl-Alt-Backspace.

Re: I need a little Xorg.conf training Please

Okay, the dpkg reconfigure command corrupted the file somehow so after a terminal file copy from backup and reboot, I made some manual changes to the xorg.conf file.

I added the optimal video mode for my new monitor and I also tailored the mode line under the screen section so it starts with 1920x1200@60 as recommended. I rebooted the system (forgot about Ctrl-Alt-Bkspace from my BSD days). The screen did auto-adjust to a new resolution, but Kubuntu sysinfo still reports 1600x1200 and I really don't see any difference or any more screen real estate like I expected.

Is there any way to verify screen resolution from a terminal?

Here's the end of my new xorg.conf file:

Code:

Section "Monitor"
  Identifier   "monitor1"
  VendorName   "Dell"
  ModelName   "2407WFP"
  Gamma      1
EndSection

Section "Device"
  Identifier   "NVIDIA Corporation NV28 [GeForce4 Ti 4200 AGP 8x]"
  Driver     "nvidia"
  BoardName   "nv"
  BusID     "PCI:3:0:0"
  Screen     0
EndSection

Section "Device"
  Identifier   "device1"
  Driver     "nv"
  BoardName   "nv"
  BusID     "PCI:3:0:0"
  Screen     1
EndSection


Section "Screen"
  Identifier   "Default Screen"
  Device     "NVIDIA Corporation NV28 [GeForce4 Ti 4200 AGP 8x]"
  Monitor    "Generic Monitor"
  DefaultDepth  24
  SubSection   "Display"
    Depth    24
    Modes   "1920x1200@60" "1280x960@60" "1280x1024@60" "1024x768@60" "1600x1200@60"
  EndSubSection
EndSection

Section "Screen"
  Identifier   "screen1"
  Device     "device1"
  Monitor    "monitor1"
  DefaultDepth  24
EndSection

You can see that I updated the "Monitor1" section for me Dell flat panel, but I don't know if X is using it or the other Monitor section. I also still don't understand why I have two Sections called "Screen." I'm not even sure if the screen section (Identifier "Default Screen") is being used by X or not. I'd really like to delete the Monitor section (Identifier "Generic Monitor") since it only applies to my old CRT, but again, I don't know what X is using. Any ideas?

Re: I need a little Xorg.conf training Please

You have default screen and screen1. The card you show is a Ti4200, the same one I have. This card has two outputs, one for a monitor and a tv out(dvi). The tv out would be screen1 your monitor would be default screen or screen0.
