[Bug 541501] Re: [RV515] [LENOVO T60] external screen display shows "shivering", horizontal refresh offset

[Gary B]

My screen (z61m also with ATI x1400) doesn't shiver horizontally as much
as vertically - it looks like vertical hold problems on an old TV.  I
hope it's the same bug.

In any case, I checked my radeon-kms.conf file, it already had 'options
radeon modeset=1' (I must have set that long ago, trying to fix other
issues with ATI back in the 8.04 install)  so I changed to modeset=0.
One immediate change after reboot was that previously, the splash screen
had been coming up in high resolution and the text in the virtual
screens (ctl-alt-F1, etc.) had been very, very tiny.  Now on the new
boot the splash is big and the text in the virtual screens is large
(same as it was in 8.04).  I have mixed feelings about the font size -
it was hard to read but allowed me to put a lot of text on the screen at
once! :)

I haven't seen the vertical hold issue again yet,.  It's been running
for about six hours.  So apparently changing the modeset works for me
too.
