Kubuntu and Ubuntu are the same in terms of kernel/drm/kms stuff. If you get a black screen after the boot splash you are not affected by this bug.
In addition this bug is about a dual-link DVI issue and has nothing to do with dual-head setups (remember, dual-link DVI is for digital signals higher than WUXGA [1920 × 1200]). So you'll have to see if there is another bug available that looks like yours or just file a new one. -- URGENT for upcoming release: Resolutions requiring dual link DVI on radeon result in no display https://bugs.launchpad.net/bugs/564559 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
