View Full Version : [mythbuntu] Nvidia, HDMI - resolution issue

February 11th, 2011, 06:49 PM
I know this has been asked a thousand times.

I followed the instructions in this thread (http://ubuntuforums.org/showthread.php?t=884211) but it doesn't quite seem to work.

I still end up with massive fonts in the panel at the top of the screen e.g "Applications" and the clock and elsewhere. I could fix this by changing the font size in Appearance settings dialogue but that doesn't seem right to me (especially as if I then connect a screen via VGA instead, the fonts are minuscule!).

A couple of differences from the solution in that post:

@ 3 - I had to select CRT-0 to get the Acquire EDID option
@5 - I used DFP-1 as this was the option in Nvidia X Server Settings when using HDMI.

I've posted my xorg.conf below and would appreciate some comments.

In the /etc/X11/xorg.conf..
comment out the modules section

Post your /var/log/Xorg.0.log

I doubt you needed to use a custom EDID..just may have needed
Option "UseEDID" "FALSE"

Did you acquire EDID with display connected by VGA cable ?
Your display will (most likely) have a different (bad) video modes for VGA compared to HDMI.

Bicycler Boy, apologies for the very slow reply - your comments are greatly appreciated.

For some strange reason the machine has, I think, decided to give me the correct resolution. Not quite sure why.

Thanks for your help.
