Other changes

  • IBus dropped from the default installation, see known issues
  • The image viewer and organizer gThumb is dropped, Ristretto is still included for photo viewing

Known issues

As with any software and software collection, Xubuntu has some bugs and issues. These include:

  • Xfce4 Power Manager does not restore screen power (1259339). You can try running xrandr, which has worked as a problem-free workaround for some users. Alternatively, to restore a working desktop go to TTY1 (Ctrl+Alt+F1) and restart lightdm with sudo service lightdm restart. NOTE: You will lose all unsaved work in progress! It appears that all instances of this bug so far are caused by suspending by closing the laptop lid - suspending from the logout dialog works to the best of our knowledge.

  • Window manager shortcut keys don't work after reboot (1292290)

  • Sorting by date or name not working correctly in Ristretto (1270894)

  • IBus is dropped from the default installation due to a high-influencing bug (1284635); the team looks to get this bug fixed soon and to reintroduce IBus in a future point release. If you are upgrading to 14.04 from a current version in which IBus is still installed but unused - you will need to either set-up IBus for your keyboard layout after rebooting or purge it. Alternatively purge IBus before upgrading.

  • Due to the switch from xscreensaver to light-locker, some users might have issues with timing of locking; removing xscreensaver from the system should fix these problems


Known issues in common infrastructure

Boot, installation and post-install

  • Automatic install is broken on drives that contain partitions that either do not have an operating system installed (eg. a user data partition like /home on Linux or D: on Windows), or partitions that have Windows 8 installed. Selecting automatic install (or upgrade) on these systems will result in the whole drive being wiped and all existing data will be lost. There are also problems dealing with systems with multiple drives. This bug is present in released media of 14.04 and 14.04.1, but is fixed for 14.04.2 and later. If you have a drive with any pre-existing partitions, or multiple drives, then you should use manual partitioning. Ensure you have backups. (1265192)

  • The desktop image installer cannot unlock existing encrypted (LUKS) volumes. If you need to make use of existing encrypted volumes during partitioning, then use the "Try Ubuntu without installing" boot option to start a live session, open the encrypted volumes (for example, by clicking on their icons in the Unity launcher), enter your password when prompted to unlock them, close them again, and run ubiquity to start the installer. (1066480)

  • When using installer to upgrade or reinstall an existing installation with encrypted swap, the installer may fail to reuse the partition. A warning will be shown, however the installation can be completed. The installed system will not have swap activated and users are advised to recreate swap on their systems. Please see advice about adding and activating swap at: https://help.ubuntu.com/community/SwapFaq (1066342)

  • Installs on very small memory systems may fail to start or exit without completing with no error. It is recommended that swap be created before install for such systems. Please see advice about adding and activating swap at: https://help.ubuntu.com/community/SwapFaq (1172161)

  • In rare circumstances the 'Next' button on the installer 'Install Type' screen is non-functional. This is intermittent and may be resolved by hitting 'Back' and retrying. (1172572)

  • On some systems, after installation, pressing 'Enter' doesn't reboot the system and a hard reset is required (1297851)

  • Live session starts with keyboard set to English US and time zone as UTC even if non-english languages are selected (1297234)

  • In OEM mode, language packs are not installed when the end user selects a non-english language and there is no notification (1307983) To install additional languages, open "System Settings -> Language Support", the language support tool will the propose to install missing language packs.

Upgrade

  • Automatic upgrade on drives containing user data partitions, including from other operating systems, and all Windows 8 systems, will result in the whole drive being wiped and all existing data will be lost. This bug is present in released media of 14.04 and 14.04.1, but is fixed for 14.04.2 and later. If you have a drive with any pre-existing partitions, or multiple drives, then you should use manual partitioning. Ensure you have backups. (1265192)

  • When the system is upgraded from a previous release via the installer, the user has to re-enter their credentials. If the user's home directory is encrypted and the password differs from the password on the pre-upgrade system, the upgrade succeeds but the user cannot login (1308530)

  • Configuration of the package tex-common fails when 12.04 LTS is upgraded to 14.04 LTS (1304972)

  • Configuration of flightgear fails during upgrade from 12.04 LTS to 14.04 LTS (1308338)

Power Management

  • On some systems, when opening lid, there is a kerneloops with a suspend/resume failure message seen. (1054732)

Desktop

  • On rare occasions Unity's Dash doesn't display (nor search for) any applications (1308037)

Migration

Graphics and Display

Networking

  • In order to improve compatibility with other local nameserver packages, NetworkManager now assigns IP address 127.0.1.1 to the local nameserver process that it controls instead of 127.0.0.1. If the system's /etc/resolv.conf is absent or is a static file instead of the symbolic link to ../run/resolvconf/resolv.conf installed by default then this static file will have to be updated by the administrator in order to continue using the NetworkManager-controlled nameserver.

AppArmor

  • The major tools in apparmor-utils AppArmor 2.8.95 have been rewritten to improve maintainability. While this allows us to better support them and add fixes going forward, currently the aa-genprof and aa-logprof CLI tools contain several bugs (1294797, 1296218) that affect their utility. These bugs should be fixed before release or in an SRU. It is recommended that people develop policy manually at this time. Update: these and other bugs with the python tools have been fixed and the new tools are expected to work better than tools in previous releases.

Kernel

  • 1292467 - Some laptops (particularly netbook class) with older graphics can experience poor graphical performance when starting with a high resolution external monitor attached. The reason for this is that some graphics cards (like the Intel 945GSE) cannot support accelerated 3D graphics when the combined width of both screens exceeds a certain threshold (typically 2048 pixels). See the bug for appropriate workarounds.
