Fedora 15 Nvidia drivers - DPI settings

[HTF]

Hello,

I've installed Fedora 15 on my laptop with Nvidia drivers however the native resolution ( 1920x1200) is to small for me. I previously used 1440x900 on Ubuntu but this resolution is not available on Fedora and there is no any other resolution that would fit to my screen (19:10) so I though that I will increase DPI.
I updated my /etc/X11/xorg.conf file as follow:

Section "Monitor"
Identifier "Monitor0"
Option "DPI" "120 x 120"
Option "UseEdidDpi" "false"
EndSection

- I also uncommented ft.dpi: 360 in /etc/X11/Xresources file but I still don't see any changes after reboot.


Could you please advise where is the issue here or if there any other solution to achieve 1440x900 resolution as the native one is really small.

Regards

I had a similar problem with the MythTV frontend system connected to my TV, except the fonts were way too big, but this solution should work for you. too.

You will need to move the:
Option "UseEdidDpi" "false"
line from the Monitor to the Device section of xorg.conf.

If moving the UseEdidDpi to the Device section doesn't seem to make a difference, try changing the line:
Option "DPI" "120 x 120"
to:
DisplaySize XXX YYY
(No quotes around XXX or YYY) in the Monitor section, where XXX and YYY are the screen dimensions in millimetres. Start with actual screen size measured values and work from there until you find numbers to your liking.

Note that the UseEdidDpi option may not be available for every video card driver. Look in the /var/log/Xorg.0.log file to see if the option is being flagged as an error, ie (EE) near the start of line showing with UseEdidDpi.

To tell if the DisplaySize option is being used, look in Xorg.0.log for a line like:
'DPI set to (168, 16; computed from "DisplaySize"'

I prefer to use the native resolution of a screen as everything will appear crisper, so, imo, adjusting the DPI is a better option than forcing a screen to a lower resolution.
Hope it helps.

My advice is to use the maximum resolution (1920x1200 or whatever) and configure Xorg to use bigger fonts if the default ones (75dpi?) are too small. This provides you with the biggest range of options.
