You've cited a "short-term solution" that has meaning only within a<br>

software tool, that is presumably<br>
part of Ubuntu's GNOME suite. </blockquote><div><br>More details below. <br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Very likely, the tool fetched some (unidentified) package, installed<br>
it, then either made some edit to the configuration files in<br>
/etc/event.d/ or to /etc/xorg.cong (but I doubt the latter even exists<br>
in your distro). <br></blockquote></div><br>Apparently, what happened is that enabling the ATI FGLRX driver allowed me to chose from a wide range of screen resolution and refresh rates. Before I enabled this non-Free driver, when I ran xrandr from the console, all I could see was this:<br>
<br>cje@rb:~$ xrandr<br>Screen 0: minimum 640 x 350, current 1024 x 768, maximum 1024 x 768<br>default connected 1024x768+0+0 0mm x 0mm<br> 1024x768 0.0* <br>

Identifier "Generic Monitor"<br> Option "DPMS"<br> HorizSync 28-64<br> VertRefresh 43-60<br>EndSection<br><br>When I tried to change screen resolutions by clicking on System > Preferences > Screen Resolution, all I saw was this:<br>

# 'man xorg.conf' says you can set the pixel clock in KHz.<br>

EndSection</p>but no joy. Still the same flicker and I am still not seeing any options other than zero when I click on <br><br>System > Preferences > Screen resolution <br><br>However, after I enabled the non-Free ATI FGLRX driver, I was able to chose from a wide variety of settings:<br>
cje@rb:~$ xrandr<br>Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1024<br>default connected 1024x768+0+0 0mm x 0mm<br> 1280x1024 60.0 47.0 43.0 <br> 1024x768 75.0* 72.0 70.0 60.0 43.0 <br>
800x600 75.0 72.0 70.0 60.0 56.0 <br> 640x480 75.0 72.0 60.0 <br> 640x350 70.0 <br> 1280x960 60.0 <br> 1280x768 60.0 <br> 1152x864 75.0 70.0 60.0 47.0 43.0 <br>

<br>Now, my problem is solved, except that I am using a non-Free driver. I am hoping that problem will resolve with Jaunty. But at least I can choose the screen resolution that I need, whereas before I downloaded the non-Free ATI FGLRX driver, I was not able to do so. Before enabling the non-Free drivers, I was using the FOSS radeohd drivers (there are two of them) which you can find by searching your repositories for radeonhd<br>
