** Description changed: + + [Impact] + + Due to a bug in GTK+2, mate-display-properties crashes when the screen + resolution is changed *outside* of it (e.g. by changing the resolution + not via that app, but somewhere else). + + The attached patches fix the issue in GTK+2 and prevent crashing of + m-d-p. + + Since this issue caused much inconvenience for users, the fix should be + backported to all current stable releases of Ubuntu. + + [Test Case] + + The easiest way to reproduce it is via Virtualbox: + + 1. Run mate-display-properties in the VM. + 2. Make the VM go full-screen. + 3. See m-d-p crash. + + [Regression Potential] + + After several months of testing the patched version of GTK+2 in Debian Jessie, I found no regressions. + I consider the regression risk very low here. + + There were originally some bugs with a few applications (notably + Spotify) crashing. We think we've backported patches to fix that - some + refcounting issues - but please check a few apps to see they still work. + + [ Original report ] + Changing extrnal screen resolution with dual mon ProblemType: Crash DistroRelease: Ubuntu 14.10 Package: mate-control-center 1.8.1+dfsg1-4 ProcVersionSignature: Ubuntu 3.16.0-6.11-generic 3.16.0-rc7 Uname: Linux 3.16.0-6-generic i686 ApportVersion: 2.14.5-0ubuntu3 Architecture: i386 CrashCounter: 1 Date: Sun Aug 3 07:09:21 2014 ExecutablePath: /usr/bin/mate-display-properties InstallationDate: Installed on 2014-08-03 (0 days ago) InstallationMedia: Ubuntu MATE 14.10 "Utopic Unicorn" - Alpha i386 (20140731) ProcCmdline: mate-display-properties SegvAnalysis: Skipped: missing required field "Disassembly" Signal: 11 SourcePackage: mate-control-center UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo
