Desktop freezes on login and while booting the ISO image

[Harjeet Singh]

Variants tested on which error found -
* Ubuntu-14.10-Desktop Final Release
* Ubuntu-Gnome-14.10-Desktop Final release

When booting the ISO (using grubentry method), the screen freezes and becomes unresponsive after 3 secs of showing up the desktop GUI screen. Not able to continue beyond that or even to the installation step. Do not face this issue with Beta 1 or Beta 2. The md5sum for iso file is OK. Problem is repeatable everytime.

I am attaching my laptop profile.

Face same issue when upgrade Utopic Beta2 release to Final Release (using apt-get dist-upgrade) and try to login.

This change was made by a bot.

Attaching syslog as well, if that helps.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Harjeet Singh (harjeetss)]

I tried mainline kernel v3.18-rc2 as suggested. It would not boot properly and took me to the intramfs screen (see attachment). Also while starting with that kernel the screen was stretched horizontally.

I have also updated BIOS to A12, the problem still persists with that BIOS version.

Status for various kernel version sis as follows :

  3.16.0-17 (Utopic-Beta2) - **WORKS**
  3.16.0-23 - Does not Work
  3.17.1 - Does not Work
  3.18.0-rc2 - Does not boot properly

[Doug Smythies (dsmythies)]

The 3.18RC2 kernel doesn't work for many people. Suggest you try 3.18RC1.

[penalvch (penalvch)]

Harjeet Singh, anything change testing 3.18-rc1?

As well, did you test v3.18-rc2-vivid, v3.18-rc2-utopic, or both?

[Harjeet Singh (harjeetss)]

I tested against v3.18-rc2-utopic as am trying Utopic install.

I have to test out 3.18-rc1 . Unfortunately since i test it out on what is my main dev laptop as do not have another machine to test on, it takes sometime in between. Will let you know soon.

[Harjeet Singh (harjeetss)]

Tested against v3.18-rc1-utopic. Does not work still (i.e. desktop freezes on login).
However does not give error like for 3.18-rc2.

[penalvch (penalvch)]

Harjeet Singh, the next step is to fully commit bisect the kernel in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
