Also seeing this issue with a fresh Lucid install on IBM T60 ThinkPad ATI Radeon Mobility X1400 IBM/Lenovo 20" Monitor
For the external monitor in Lucid, setting refresh rates of either 70Hz or 72Hz results in an "Input signal out of range" message on the external monitor. In Karmic, either of those settings (as well as 60Hz & 75Hz) worked fine. Setting a 75Hz refresh rate shows less of the 'vibration' effect, but it's still quite bad. I don't think this is particularly relevant, but the Lucid Monitor Preferences dialog identifies the external monitor as 'Lenovo Group Limited 20"', while the Karmic dialog identified it as simply as 'Lenovo 20"'. -- [Lucid AMD64] Dual monitor distortion / crash - ATI mobility Radeon X1400 https://bugs.launchpad.net/bugs/573290 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
