Re: HOWTO: change resolution/refresh rate in Xorg
I did try a custom modeline. My xorg.conf included this:
Section "Monitor"
Identifier "aticonfig Monitor 0"
HorizSync 31-101
VertRefresh 60-160
# V-freq: 85.00 Hz // h-freq: 94.05 KHz
Modeline "1400x1050" 211.42 1400 1512 1768 2248 1050 1050 1054 1106
EndSection
Section "Monitor"
Identifier "aticonfig Monitor 1"
HorizSync 31-101
VertRefresh 60-160
# V-freq: 85.00 Hz // h-freq: 94.05 KHz
Modeline "1400x1050" 211.42 1400 1512 1768 2248 1050 1050 1054 1106
EndSection
I saw no difference with this configuration.
The thing that looks wrong to me is that the NoDDC and IgnoreEDID options are being ignored by the ATI driver. Is the syntax different? Is there some other way to get the driver to ignore the EDID?
Re: HOWTO: change resolution/refresh rate in Xorg
Just a guess, but you could try:
Code:
Option "UseEdidFreqs" "0"
Re: HOWTO: change resolution/refresh rate in Xorg
Hi,
Very nice guide. I just want to make a small suggestion. In the end, instead of restarting gdm, one should first test if the configuration is right. As most newbies wouldn't know what to do if their X is lost, it's better to do
where one can see the result on a new X (ctrl+alt+F9) without losing the first. If something goes wrong, one can easily use the backup configuration under their surviving X (ctrl+alt+F7).
Re: HOWTO: change resolution/refresh rate in Xorg
I tried this, and got the same message in /var/log/Xorg.0.log indicating that the setting was not used/recognized:
(WW) fglrx(0): Option "UseEdidFreqs" is not used
Is this the right place to be asking this question or should I be trying to ask someone at ATI?

Great tip :D thanks! Would anyone mind telling me, though, how to stop that secondary X once it's started? Very useful, not having to restart the computer and all :P could have saved me half an hour at least as I'm working with this xorg stuff
Re: HOWTO: change resolution/refresh rate in Xorg
No one out there has any ideas?
Thanks for anything!
Re: HOWTO: change resolution/refresh rate in Xorg
This is the crummy response I got from ATI:
"
ATI does not provide direct technical support for laptops/notebooks at this current time (telephone or email). If you require direct technical support please contact the system manufacturer of your laptop/notebook.
"
ugh... i'm out of leads on this. i am afraid that i'm going to have to give up on ubuntu. i have had *constant* problems with the wireless and video card drivers. Basic functionality doesn't work well: vpn, docking, hibernation. I can't easily install current versions of core software: firefox. And the desktop search is still mediocre and broken: beagle.
The tools that I'm using linux for (emacs, ethereal, apache, gimp and a good terminal) have major problems running on windows, but I can use cygwin and run them on a server.
I had high hopes for ubuntu but when current off the shelf hardware requires many hours of tinkering, and even then you don't end up with a robust system, what's the benefit? I've had ubuntu crash on me and demonstrate more instability than any windows installation i've ever used.
Re: HOWTO: change resolution/refresh rate in Xorg

The command "sudo /etc/init.d/gdm stop" should only get you to the command line (you won't see the Desktop Environment GNOME or KDE). Are you sure it restarted you computer?
Re: HOWTO: change resolution/refresh rate in Xorg

thanks for helping
