Does this occur on hardy? There's been a number of randr improvements to -ati since Gutsy. I've tested on several ATI cards and did not see this particular issue, although sometimes the list of available resolutions is limited.
If it does still occur, please attach your /var/log/Xorg.0.log from right after attempting to connect the external monitor. -- External monitor does not work with radion mobility M300 https://bugs.launchpad.net/bugs/78228 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
