Created attachment 11409 [details] [review] output of xrandr --verbose This should be fixed in ati git master. The flicker problem seems to be fixed indeed - we cannot reproduce with yesterdays git. Thanks! But the invalid values in the modeline are still present. Shall I file a separate bug for this? Thanks again and greetings (In reply to comment #4) > The flicker problem seems to be fixed indeed - we cannot reproduce > with yesterdays git.

As long as it works you should be ok. |

We have a Notebook Thinkpad R52 with internal panel 1400x1050. The internal panel shows a flickering screen (looks like a moire-effect) and so we checked the server log and the xrandr-output (both attached). We found an interesting line in the Xorg.log (and in the xrandr- output): (II) RADEON(0): Printing probed modes for output LVDS (II) RADEON(0): Modeline "1400x1050"x60.2 108.00 1400 34200 34312 1688 \ 1050 1051 1054 1063 (64.0 kHz) I have no idea whether this is related to the flicker problem, but in any case - something is wrong, probably an underflow and hope- fully the driver does not try to use these values for the panel :-) We did not have the flickering problem with the "old" radeon-driver without xrandr 1.2 support. I have learned that much of the mode handling is done in the server so this may also be a server problem. This is a Fedora 7 1.3 server, I scanned through the fedora specific patches but found not much related to mode resp. modeline handling.
