hi,
I am having troubles with flicker on my Intrepid (GNOME) system. I am using a 19 inch CRT monitor and here is my video controller card from lspci:
VGA compatible controller: ATI Technologies Inc RS690 [Radeon X1200 Series]
My screen resolution is 1024 x 768, but when I go to
System > Preferences > Screen Resolution
I see that the refresh rate is zero! No joke! There is also no opportunity to choose a different refresh rate with that Screen Resolution tool, and I have been told that Intrepid does not use the file
/etc/X11/xorg.conf
and so modifying that file will not work.
I have installed these drivers:
xserver-xorg-video-radeonhd
xserver-xorg-video-radeonhd-dbg
As suggested by this page:
http://wiki.cchtml.com/index.php/Ubuntu_Intrepid_Installation_Guide
But apparently I need to somehow "turn on" those drivers, and I am not sure how to do it. Any tips welcome. Thanks!
