Add support for blacklisting some drivers from using unredirected fullscreen windows

Bug Description

Note: the blacklisting is only needed on precise. If/when included in quantal, it doesn't do anything practical since the blacklisting default only blacklists Mesa 8.0 drivers.

[Impact]

Some drivers can be broken when using unredirect fullscreen windows. For those drivers, there has to be a way to disable this feature.

IMPORTANT For Quantal: although currently for quantal there are no drivers that are to be blacklisted and theoretically this feature is not needed there. But we still think that this branch needs to be included as an SRU for quantal. The main reason is that without it, backporting fixes from trunk will become much more complicated, as most branches will have to be modified additionally. The feature itself is tested not to have any regression potential.

[Test Case]

No clear test case, one possibility is to:
1. Start a system running on one of the blacklisted drivers (noveu, Intel).
-> Make sure unredirect fullscreen windows is not running

[Regression Potential]

Not working unredirect fullscreen windows on all drivers.

This is a prerequisite before we can resolve bug 1063690 on precise.

Hello Daniel, or anyone else affected,

Accepted compiz into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/compiz/1:0.9.7.12-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Tested that blacklisting (intel) works correctly with the default setting, and if the setting is removed unredirecting gets enabled again. The nouveau part of the blacklist string should work similarly.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package compiz - 1:0.9.7.12-0ubuntu1

windows at all (LP: #1041066)

- Unredirected fullscreen windows freeze and stay on top when wall
sliding (Ctrl+Alt+Left/Right) (LP: #1084401)

(LP: #1051802)
- HTML5 video in Firefox continues to tear (LP: #1086337)
- Add support for blacklisting some drivers from using unredirected
fullscreen windows. By default intel and nouveau on Mesa 8.0
are blacklisted, configurable via ccsm. Users can upgrade to
Mesa 9.0 around 12.04.2 time. (LP: #1089246)
- Unredirect fullscreen windows should be the default for optimal
performance (LP: #1063690)
* debian/patches/workaround_broken_drivers.patch:
- Updated to apply.
* debian/patches/force_unredirect_enabling.patch:
- Enable unredirect_fullscreen_windows unconditionally. Because of
gconf hurdles we can't easily migrate existing users into the
new default otherwise. Unredirection can be easily disabled with
the new unredirect_match option, by blanking it completely,
including removing the '(any)' part.
* debian/patches/compiz-package-gles2.patch:
- Update for the new blacklisting feature as well
* debian/patches/blacklist_no_xml_double_escaping.patch:
- Cherry-pick fix for the default string (LP: #1091103)

[ Michael Terry ]
* debian/patches/blacklist_no_xml_double_escaping.patch:
- Update to also blacklist Mesa 9.0, which precise users may have from
the x-updates PPA. 9.0 seems to have similar problems as 8.0 on
Intel hardware.
