Ubuntu

DPI is not recognized by UBUNTU, so fonts, icons and the whole system is too small

Asked by Pkhetan

Hi,

I'm using a 147x145 DPI screen. The fonts, icons and all the whole system seem too tinny.

If I change the System>Preferences>Appearance>Fonts>Details...>Resolution from 96 to 145, the fonts of the desktop get better, but the icons still too tinny, and the fonts in any other applications is still tinny.

I know that i can change the resolution of the screen to a smaller one (actual is 1920x1200) but i don't want to do that because it downgrade the quality of the display.

in Firefox, i can use Ctrl + to increase the fonts size, but this leads sometime to bigger fonts in small frames so sometimes i can't see all the fonts in a frame, or the frames can interfere with each others, and the enlarged photos are really bad quality.

My question is :

Is there a real way to make all the fonts, icons, photos and the whole system in all the applications to appear in a normal size instead of this tinny size that i get only because i have a 1920x1200 on a 15" screen ?

in termianl :

~:/var/log$ grep DPI Xorg.0.log

(--) NVIDIA(0): DPI set to (147, 145); computed from "UseEdidDpi" X config

~$ xdpyinfo | grep reso

  resolution: 147x145 dots per inch

And this is the right DPI of my screen 1920x1200 pixels (332x210 millimeters), but i don't know why the operating system is not applying these DPI?

My config :
Clevo M860TU with Quadro FX 2700M
UBUNTU 9.10 ( but this problem was also in earlier releases )
Driver : NVIDIA 185 ( but i tried also 173 )

Thanks

could u try 'nvidia-settings' to tweak.

$ sudo nvidia-settings

maybe, u will need to install it.
also, u can try 195 drivers: https://edge.launchpad.net/~nvidia-vdpau/+archive/ppa

In nvidia-setting > X screen 0 > X screen information > Resolution : 147x145 dots per inch. So it already recognize the right DPI and any way I can't change this information in this place, it's only for information not configuration; unless you know other place in nvidia-setting where you can configure the DPI. If yes, please provide.

For the 195 driver, i have tried the UBUNTU Lucid alpha which has a 195 driver and it had the same problem. What is strange that all the Xorg.0.log & xdpyinfo nvidia-setting recognize the right DPI, then why the operating system doesn't use that DPI?

so, i see. i propose to create bug report / convert this question by just clicking on not link 'Create bug report' =).

after bug created u can use number for following command:

$ apport-collect <bug_number> -p xorg OR nvidia-glx-185 OR nvidia-glx-195

just before reporting bug, could u try disable NVIDIA drivers and try xorg drivers to be sure NVIDIA issue only.

When i remove the NVIDIA proprietary driver, nothing change for the small display problem but these change :

~:/var/log$ grep DPI Xorg.0.log
(==) NV(0): DPI set to (96, 96)

~:/var/log$ xdpyinfo | grep reso
  resolution: 147x147 dots per inch

I'll report a bug

Thank you
