[Bug 372911] Re: Wrong resolution on ATI Radeon HD 4670 after connecting an HDMI output device

 

I have found a similar problem described for a different video card,
look at bug 281486 .

I have applied the following workaround as described on the bug comments
(it works):

In order to do this, edit the /etc/gdm/Init/Default file (a script run @
the start of gdm), and insert a line similar to the following:

xrandr --output VGA --auto

Where "VGA" is the output name of your external monitor (can be found by
looking at the output of "xrandr -q").

** Summary changed:

- Wrong resolution on ATI Radeon HD 4670 with an HDMI output device
+ Wrong resolution on ATI Radeon HD 4670 after connecting an HDMI output device

--
