font anti-aliasing and dpi settings

How to change font anti-aliasing and dpi settings in lxde? lxappearance doesn't look like it has an option for these...

thanks in advance for any replies...

As far as I know, font antialiasing should Just Work. It may be that you have some leftover on your system that is preventing it. As to DPI, this should be automatically calculated by the X server when it starts from the monitor-reported EDID. Why don't you take a look in your /var/log/Xorg.0.log for clues if your monitor isn't set correctly at startup, and work with your distro to solve these issues. They know what configuration files they ship and how their startup is intended to work.

thanks Marty. I need to change the hinting to full for the anti-aliasing settings and xorg somehow messed up the dpi settings for my monitor. Looks like there is no gui tool in lxde to do that. I'm attaching the screen shot of a similar tool found in xfce.

A bit of searching indicates those settings might be in ~/.Xdefaults, which you could certainly edit by hand.

!Xft settings
Xft.dpi: 96
Xft.hinting: 1
Xft.hintstyle: hintfull
Xft.antialias: 1
Xft.rgba: rgb

For now I'll take it as an investigation item to see if we should be adding this to LXAppearance.

On Debian just run dpkg-reconfigure fontconfig-config

Or edit .fontconf

</fontconfig>

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font" >
<edit mode="assign" name="autohint" >
<bool>true</bool>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="rgba" >
<const>none</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="hinting" >
<bool>false</bool>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="hintstyle" >
<const>hintnone</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="antialias" >
<bool>true</bool>
</edit>
</match>
</fontconfig>

You check the dpi easily enough.

$ xrdb -query
*customization: -color
Xcursor.size: 16
Xcursor.theme_core: true
$ xdpyinfo | grep resolution
resolution: 95x96 dots per inch

I am trying out Debian Squeeze with LXDE.
debian-live-6.0.3-amd64-lxde-desktop.iso
I could not find a simple interface for Font Aliasing, Hinting and DPI as was available in Xfce.
In Xfce I could set hinting to 'slight' and adjust a few other settings.
The current LXDE in Debian Squeeze does not have that facility, although it may have been added to Debian unstable.
So I decided to search the forums.
I tried some of the methods posted on the forums (some posts were quite old and so some of the solutions didn't work anymore).

The 'fonts.conf method' does work (with most of my apps including Iceweasel) but not with my latest version of Opera browser (11.60 build 1185) which seems to ignore fonts.conf.
Through experimentation and research I have found that creating a file named .Xresources instead of fonts.conf works for all my apps including my latest Opera browser.
https://wiki.archlinux.org/index.php/Xresources
Note: ~/.Xdefaults is deprecated, so use ~/.Xresources instead.

! Xft settings ---------------------------------------------------------------

Xft.dpi: 96
Xft.antialias: true
Xft.rgba: rgb
Xft.hinting: true
Xft.hintstyle: hintslight

Logout and Login for the settings to take effect.
I hope this helps someone and saves them some time and I also hope it works for people who were about to give up and revert back to Xfce (excellent though it is).
