SOIMiMozO, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc2 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-203 needs-upstream-testing regression- potential ** Summary changed: - ASUS Taichi21 External screen doesn't work. + [ASUS TAICHI 21] External screen doesn't work. ** Description changed: - This report is another entry for the bug#1205694 described - here:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1205694 - - External screen on ASUS Taichi21 ultrabook doesn't show anything.
