As is to be expected at this stage of the release process, there are several known bugs that users are likely to run into with Ubuntu 9.04 Beta. We have documented them here for your convenience along with any known workarounds, so that you don't need to spend time reporting these bugs again:

 * The "encrypted home directory" option that was available in the desktop installer in previous alpha milestones has been disabled due to outstanding issues and will not be enabled as an install option for the final release.

 * A new XServer, version 1.6, is included in Ubuntu 9.04 Beta. The binary proprietary fglrx driver is not yet supported for this server and will exhibit various serious issues if run against it. Users of this driver are encouraged to wait or to switch to the open source -ati driver in the meantime. Bug:313027

 * Users of Intel i845 or i865 video chipsets are unable to load X, getting an error message of "Fatal server error: Couldn't bind memory for BO front buffer". Users on these systems are advised to wait for a resolution to this bug before upgrading. Bug:304871

## * The OEM mode on Kubuntu images fails after reboot in Jaunty Alpha 5. Investigation of this issue is ongoing. Bug:309482

 * Ctrl-Alt-Backspace is now disabled, to reduce issues experienced by users who accidentally trigger the key combo. Users who do want this function can enable it in their xorg.conf, or via the command {{{dontzap --disable}}}.

 * Font sizes may be abnormally small or large on monitors which mis-report their capabilities. If you suspect this may be the case, please see [[X/Troubleshooting/HugeFonts]] for steps to troubleshoot this issue.
