This is an 14.04 installation packaging issue because I'm running 14.04 now on this laptop upgraded from 13.10

Please let me know what other information you'll need.

Can you see if this issue also happens with the latest development release, which can be downloaded from:

cdimage.ubuntu.com/daily-live/current/

[Jerry Ji (jerryji1976)]

I confirm that this bug is absent from yesterday's (May 28th) image ( utopic-desktop-amd64.iso ).

So the fix will be back-ported and a new 14.04 (desktop) image will be released soon, right?

Jerry Ji, thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1324085/comments/4 the bug has been fixed in the latest development version of Ubuntu - Utopic Unicorn.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention. As well, one would want to fully reverse commit bisect the kernel in order to identify the fix commit as outlined in https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F .

This bug is fixed in Utopic Unicorn, but how about Trusty Tahr? I disagree with closing this critical bug because:

1. So many Dell XPS L502X owners out there are not able to install 14.04 (directly) due to this bug

2. It may also affect other similar models

3. If I mess up with my system in the future, I can only boot back with 13.10 or 14.10 release image, but not 14.04

In summary, I find it mind-boggling to leave such a critical installation bug in a LTS release.

Instead of seeking to "reverse commit biset the kernel", why not just package a new 14.04 release image (with the proper kernel)?
