[gentoo-user] Very small fonts after re-emerging xorg-x11

Hi!

Yesterday I re-emerged xorg-x11 and all my nvidia ebuilds (glx, kernel and settings) after unmasking
nvidia-* by ~x86, and adding dlloader to my USE flags (yes, it was not enabled by default, as I use
- -* and package-per-package use-flags).

After re-emerging that, I restarted xdm/kdm and when I logged in I found all fonts to be quite
smaller... to the level of thinking I had a bigger resolution :P (I use 1024x768 maximum).

Any idea?

What information can I provide?

Hi,
I used to have the same problems every time I upgraded xorg until I
found information about passing the screen dimensions in the xorg.conf
file so the server can determine (calculate) the DPI.

Basically, you can provide the screen dimensions in millimiters in the
following manner:

Section "Monitor"
    Identifier "CRT-2"
    VendorName "Sony"
    ModelName "CDP-G400"
    DisplaySize 355 264
EndSection

This way you'll get a consistent DPI for your display even after upgrading xorg.


Another way of achieving this is, if you do not boot right into
KDM/XDM, you log into the console and pass a DPI value when starting
xorg:

startx -- -layout <Your server layout of choice> -dpi 96

As you can see, in the example I am forcing a DPI of 96.

Hope this helps.

I have something like this:

Section "Device"
	Identifier  "Card00"
	Driver      "nv"
	BusID       "PCI:1:0:0"
	Screen      0
	Option	    "DPI" "100 x 100" # <-------- this is place to play!
EndSection

 Very nice! However, where does one find some sort of matix listing of screen
screen sizes, aspect ratios and the corresponding dimentions in mm ?

I do not know that...

I had to actually measure my monitor!! :-)

But I think a better solution has been mentioned in one of the
responses above, the one that uses a "DPI" option...

Ragards,

Why do you need a matrix?  Just measure and enter the actual
dimensions of your display.
Or if you want a specific DPI, do the math.  For example, for
1280x1024 at 100dpi:

width = 1280pix / 100pix/in -> 12.8in * 25.4mm/in -> 325mm
height = 1024pix / 100pix/in -> 10.24in * 25.4mm/in -> 260mm

So the dimensions should be 325x260.

Are you sure about this?  DPI is not a standard option for the Device
section, and doesn't appear in the nv man page.  It is valid for the
nvidia driver, but I think if you check /var/log/Xorg.0.log, you will
find that this is generating an error message with the nv driver...

Richard,

You are right, this is my mistake - the Option is nvidia driver trace :-)
There *is* a string:

(WW) NV(0): Option "DPI" is not used

For a 1440x900 portable;

       DisplaySize 366 229

worked great.

Thanks Richard!

DisplaySize 366 229     # display size in mm for DPI auto set

 width = 1440pix / 100pix/in -> 14.4in * 25.4mm/in -> 366 mm
 height = 900pix / 100pix/in -> 9.00in * 25.4mm/in -> 229 mm

Works like a champ on a 1440x900 portable screen.

thx,

James
