Description Andrew.Chatto 2008-11-23 16:27:39 UTC
Description of problem:

Huge fonts in gdm and gnome.  I think it may be a problem with EDID

I have a Samsung LN-T4661F TV connected via DVI-HDMI cable.  The resolution is correctly set to 1920x1080 and looks fantastic.  The fonts, however, are HUGE.  If I create a xorg.conf with Option "DDC" "off", the fonts are correctly sized.  However, they are very blocky and hard to read.  Everything else is rendered wonderfully.

I can also call startx -- -dpi 96 and get the same results (good size but horrible rendering of fonts.)  I've read elsewhere (in Ubuntu forums) that this kind of thing is frequently because of bad EDID discovery.  

Version-Release number of selected component (if applicable):

Fedora 10 Preview fresh install, as well as with all updates.
xorg-x11-drv-i810-2.5.0-3.fc10.rpm

How reproducible:


Steps to Reproduce:

Actual results:

Huge fonts, fabulous graphics (the Fedora default blue sun in the background looks amazing.)

Expected results:

regular sized fonts.
Additional info:

I'll attach the Xorg.0.log, 

xrandr looks like this...

Comment 2 Matěj Cepl 2008-11-24 09:40:46 UTC
(I don't know why you bother with leaked versions, when we officially leak it on http://fedoraproject.org/get-prerelease ;-))

Anyway, could we get /etc/X11/xorg.conf as well, please?

xorg.conf that I use to get regular sized fonts (they are poorly rendered, however)

I didn't use an xorg.conf.  Fedora 10 does not generate one by default.  I've attached the one I used to try to fix the situation (although I'm no expert at these things.)   If you comment out the 'Option "DDC" "off"' line, you get the huge fonts.  With that line, you get correctly sized fonts that look blocky.

In addition, I didn't know what you meant by 'leaked versions'.  I installed the Fedora 10 preview from the links you showed.

Comment 4 Bug Zapper 2008-11-26 05:49:27 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:

Comment 5 Adam Jackson 2009-02-10 15:50:25 UTC
The DPI thing should be sorted in rawhide, as of 1.5.2-4 or thereabouts.  So, should also be fixed in F10 updates.

I still have the problem of large fonts in GDM in Fedora 11.

$ rpm -q xorg-x11-server-Xorg 
xorg-x11-server-Xorg-1.6.4-0.1.fc11.x86_64

I can set them just fine in the actual GDM session, but there doesn't appear to be away to fix in the GDM greeter.  I also have a Samsung LCDTV set very similar to comment #0.
