<pre wrap="">Morning all,
I wonder if anyone can help here - I have an Advent 4312 which runs
beautifully in Ubuntu, but when I plug in my Chuntex 16" monitor
(formerly CTX) I can only get 1152x864 resolution. I have checked the
xorg.0.log file and hal is deciding that any higher resolutions are not
supported by the monitor (which they are - to at least 1280x1024).
xorg.conf doesn't have any reference in it at all to VGA1 which is the
external monitor.
Searching the web I have noticed that there are a number of issues
around the new xorg subsystem and the suggestion is to use xrandr to
generate a new mode and use that. The problem I now have is that I
can't find all the requisite settings to create the new mode - clock,
refresh etc.
Has anyone had any success overriding hal and forcing true resolutions?
Cheers,
DM

<pre wrap=""><!---->Yes thanks,
If you use google and type in xorg resolution calculator that should
give you the line you require for xrandr. I'll double check for the
site tomorrow for you.

Cheers Dave - You de Man... ;-) Through your suggestion I have found
the gtf tool. Simply provide the x y and refresh values, and it spits
back a mode line that can be used in xrandr:<br>
$ gtf 1280 1024 60<br>
<br>
# 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz<br>
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025
1028 1060 -HSync +Vsync<br>
<br>
$ xrandr --newmode Andy 108.88 1280 1360 1496 1712 1024 1025 1028 1060<br>
$ xrandr --addmode VGA1 Andy<br>
<br>
All I need to do now is work out how to automate this and persuade xorg
to put the monitors in the correct sequence, but that can wait for a
while - at least I can now see what I am doing :lol:<br>
