Good that you found a workaround to the issue. It's still a valid bug because a VT switch shouldn't be required to make the resolution changes take. Also, it is a driver issue in fact, since the underlying logic for implementing the resolution changes are inside the driver; this issue doesn't occur on -intel for instance.
Anyway, guess next step is to forward this bug upstream. -- External monitor resolution can't be changed on laptop (ati driver) https://bugs.launchpad.net/bugs/227520 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
