= Known Issues (Core) =
== Boot, installation and post-install ==
 * In Virtualbox, the installer currently has a bug where after the installation is complete, the installation medium will eject, but you will be unable to press ENTER to reboot. Powering off and back on should boot you into your installed system. This is being tracked in bug Bug:1447038
 * The amd64 (Intel x86 64bit) images specifically targeted at Apple hardware (amd64+mac) are no longer produced. Most Apple computers are now capable of booting the amd64 image directly using the EFI (not legacy) boot method so long as their firmware is up to date. If for some reason your hardware doesn't boot properly using the amd64 image, make sure you don't have a pending EFI update and if that still doesn't ##work, then patch the 64-bit ISO using the software in [[https://bugs.launchpad.net/ubuntu-cdimage/+bug/1298894/comments/16|bug #1298894]] (tested working on Macbook 2,1). Alternatively, simply use the ##i386 (32bit) image instead.
 * Due to changes in syslinux, it is not currently possible to use usb-creator from 14.04 and earlier releases to write USB images for 15.04; we believe that it is also not possible to use usb-creator from a 15.04 system to write USB images for earlier releases. For now the workaround is to use a matching release of Ubuntu to write the images, but we intend to issue updates soon to work around this incompatibility. [[Bug:1325801]] (Lubuntu suggested workaround is to use [[https://help.ubuntu.com/community/OBI|OBI]] which is not affected by this problem).
## * On OEM installations, after the end user configuration in a different language than the default initial ##OEM installation, extra language packs are not installed (Bug:1446539) You can install extra language packs ##by selecting "Language Support" in "System Settings". A dialog will prompt you to install missing language ##packs.
## * During installation on a ''blank disk'' on a UEFI system, if the user creates custom partitions, the ##installer displays a 'Force UEFI installation?' dialog while there is no pre-installed system ##(Bug:1447256). This dialog is not displayed if the custom partitioner is not used. This message is harmless ##since no previous installation exists on the system and you can proceed with the installation.
##* Systems running multipath with a very large number of paths might experience long delays and issues ##during boot (for example, failure to mount the root filesystem or other filesystems); for details and ##work-around see bug Bug:1467989.
## * On DELL XPS 13, the EFI partition is wiped if the option "wipe whole disk and install" is selected in ##the partitioner (Bug:1499323) The EFI partition and the boot can be restored by following the instruction ##documented in the bug report.
##
 * The Unetbootin versions in the Ubuntu repos are old ([[https://bugs.launchpad.net/ubuntu/+source/unetbootin/+bug/1497604|1497604]]) (Lubuntu suggested workaround is to use [[https://help.ubuntu.com/community/OBI | OBI]] which is not affected by this problem).
 * Guided partitioning shortcut "max" gives minimum space instead [[http://launchpad.net/bugs/1163908 | 1163908]]
Line 103: Line 94:
 * If several keyboard layouts are configured before upgrade, the wrong layout might be selected after upgrade (Bug:1447157) Re-select the keyboard layout of your choice from the keyboard indicator or system-settings to make it the default. This setting will then persist upon reboot.

New Features in Lubuntu 16.04 LTS

  • Kernel is now the 4.4 LTS kernel to sync with the 16.04 release.
  • General bug fix release as we prepare for LXQt.
  • Many LXDE components have been updated with bug fix releases.
  • An update of the artwork (more icons, theme update, more compatibilities ...).
  • lubuntu-extra-sessions: In the past, selecting different sessions (netbook, gaming etc.) was installed by default. This is now an optional extra that can be installed by those who want this added functionality.
  • Lubuntu PPC Mac images are available in this LTS release.

Lubuntu Applications

System Requirements

Lubuntu is a good operating system for many old computers, but not for all of them. Some computers have too little horsepower or memory. A rule of thumb is that the computer should not pre-date 2000. The desktop images for lubuntu 16.04 requires a DVD / USB device to write it to, the alternate images are for those with have non-standard setups or Low RAM.

Memory (RAM)

For advanced internet services like Google+, YouTube, Google Docs and Facebook, your computer needs about 1 GB of RAM.

For local programs like LibreOffice and simple browsing habits, your computer needs about 512 MB of RAM. See minimal for systems below that RAM.

Processor (CPU)

The minimum specification for CPU is Pentium 4 or Pentium M or AMD K8.

Older processors are too slow and AMD K7 has problems with flash video.

Graphics chip / card

Nvidia, AMD/ATI/Radeon and Intel work out of the box, or the system can be tweaked to work fairly easily. You can get help at the Ubuntu Forums. With such graphics, or if you don't know, try the current Lubuntu version.
