Hi, The reasons for marking this as a certification blocker are three-fold:
1- This is a blocker for laptops and netbooks where plugging it to an external display is a common use case. 2- Although the workaround is simple, it's also not very obvious, and it's bound to leave users quite confused as to what to do / dissatisfied with the quality of the OS. 3- Per Certification policy, bugs that affect systems for which enablement work has been done (as is the case here) are marked as blocks-hwcert. Also, regressions (also the case) are marked as such. So systems here are of the highest priority to get this problem looked at, from the Hardware Certification point of view. @Sebastien: Affected systems are using Intel, NVidia and ATI/AMD chipsets. See comment #9 for a link to a table with some specs and comments on affected systems. So far all affected systems are running Unity; those that start a Classic session don't seem to be affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled upon restoring original resolution or connecting external displays -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
