Upgrade to 2.6.32-27 breaks Compiz

[Philip Whateley]

(Apologies if I have not followed the correct protocol for reporting bugs - I have not had to file many reports, and would welcome feedback on improving reporting)

Upgrading to 2.6.32-27 appears to break Compositing. Restarting Ubuntu after update switches to basic graphics and Compiz cannot be restarted.

Output of compiz-check (http://forlong.blogage.de/entries/pages/Compiz-Check) is as follows:

Gathering information about your system...

Distribution: Ubuntu 10.04

Desktop environment: GNOME

Graphics chip: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

Driver in use: vesa

Rendering method: AIGLX

Checking if it's possible to run Compiz on your system... [SKIP]

Checking for hardware/setup problems... [SKIP]

At least one check had to be skipped:

Error: vesa driver in use

Would you like to know more? (Y/n) Y

The vesa driver is not capable of running Compiz, you need to install

the proper driver for your graphics card.

Check if there's an alternate (proprietary) driver available? (Y/n) Y

Compiz was working fine with 2.6.32-26, so I assume that the correct graphics drivers are installed. Please advise if you need further information and I will provide it.

[Philip Whateley (philip-whateley)]

Further to bug report above, I have tried reverting to 2.6.32-26 and then 2.6.32-27 repeatedly (only checked once before filing bug). On the third cycle, I was also able to get Compiz working on 2.6.32-27.

compiz-check now shows:

Not sure why graphics drives were not being picked up, but it looks like it's my problem - many apologies for wasting time.

Hi Philip,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
