KDE font resolution

[Rumpty]

Running a clean install of Kubuntu. Monitor resolution 1024x768. In the quest for nicer looking fonts, I have been trying to change the system resolution to 96dpi, without success. Had no trouble doing it in Ubuntu (Gnome) which is on another partition, but in Kubuntu, no luck.

Tried the DisplaySize 270 203 entry in xorg.conf, which worked in Ubuntu, but it has no effect in KDE on my machine. Then I tried putting -96 dpi into the ServerArgsLocal line in /etc/kde3/kdm/kdmrc. This changes things, but the result is strange. With the entry -96 dpi, xdpyinfo reports a resolution of 77x72 dpi. If the -96 dpi entry is changed to (for instance) -124 dpi, xdpyinfo reports a resolution of 99x93 dpi! (After rebooting)

Can anyone tell me what is going on, and why I don't get the expected resolution please? Should I expect xdpyinfo to report 96x96 with the -96 dpi entry in kdmrc, or have I got things wrong?

Yes, you should expect xdpyinfo to display 96x96 dpi after adding the -dpi 96 parameter to kdmrc... At least that's how I got it to work, but I have no idea why it isn't working in your setup... good luck anyway !

Double check that you put DisplaySize 271 203 in Section "Monitor". Instead of 270, try 271 or more (276, 280,... experiment). Same for the other value.

Thanks for the tip. I'll experiment more with the numbers.

Maybe the dpi is calculated for the wrong screen resolution.
Can you post /etc/X11/xorg.conf and /var/log/Xorg.0.log (as attachments).

Sorry for hijacking this thread, but the issue i'm having is <kindof> the same.
Everytime i make a clean install, using the nv driver gives me the correct font size. And also, everytime i install the "nvidia" driver all fonts get rather big. This bugs the *hell* out of me really, and i havent figured out how to get my old state back. why, is this happening?
I dont think DisplaySize was set before, and it isn't now so what made the difference...
As always, any suggestions would be greatly appriciated.

Yep, the nv driver does that indeed. I solved the oversized font issue by setting DisplaySize to get 96dpi.

i was having the same problem with my nvidia card using the latest nvidia driver on debian stable and heres how i fixed it, the same steps should work just fine with ubuntu also.
edit your /etc/X11/xorg.conf file and scroll down to the "Device" section and add this after the BusID

	Option		"UseEdidDpi" 		"FALSE"

it should look something like this

Section "Device"
	Identifier	"NVIDIA Corporation NV18 [GeForce4 MX 4000 AGP 8x]"
	Driver		"nvidia"
	BusID		"PCI:1:0:0"
	Option		"UseEdidDpi" 		"FALSE"
	Option		"NoLogo"
	Option 		"RenderAccel" 		"true"	
EndSection

then follow the steps here http://www.ubuntuforums.org/showthread.php?t=20976
to find the display size option for your resolution
i use 1024x768@85hz so mine would be

	DisplaySize	270	203

and add that to the "Monitor" section mine looks like this

Section "Monitor"
	Identifier	"COMPAQ FS7600CPQ"
	HorizSync	30-70
	VertRefresh	50-160
	Option		"DPMS"
	DisplaySize	270	203
EndSection

save the file and restart the xserver now when you run
xdpyinfo | grep resolution
it should display
resolution: 96x96 dots per inch
hope this helps.

I acctually followed this guide
http://www.ubuntuforums.org/showthre...e+fonts+nvidia
yesterday, wich is essentially what you recommended, but it didn't work. But with your UseEdidDpi option it did

Option "UseEdidDpi" "FALSE"

Thanks man, you truly are my hero

[obibok]

Instead of calculating DisplaySize, apparently you can simply set DPI in a clear way:

Option   "UseEdidDpi"   "FALSE"
Option   "DPI"   "96 x 96"

I haven't tested this but if you want to give it a shot and post your comments, others could learn something too
