    Known Lucid Lynx issues/bugs with workarounds

    Disclaimer : The purpose of this thread is to list known Lucid Lynx issues and bugs, and give the corresponding workarounds and launchpad entries.

    Feel free to propose other known Lucid Lynx bugs to be listed here but please provide a link to the workaround and a link to the corresponding launchpad entry.

    -------------------------------------------------
    Warning: Before upgrading or attempting a reinstall make sure you backup essential files.
    Please read the Release Notes:-

    http://www.ubuntu.com/getubuntu/releasenotes/1004

    Upgrade 8.04 -> 10.04 can break apt-get.
    The package flashplugin-nonfree has been problematic when upgrading 8.04 -> 10.04 and breaks apt-get;

    Bug Report

    For those not wanting to read the bug report in detail, the fix is :

    Code:
    sudo rm /var/lib/dpkg/info/flashplugin-nonfree.prerm
    
    sudo dpkg --remove --force-remove-reinstreq flashplugin-nonfree
    sudo dpkg --purge --force-remove-reinstreq flashplugin-nonfree
    Nautilus location bar, bread crumbs vs text based.
    Breadcrumbs is now the default. The button to switch between the two has been removed. Users can switch with ctrl+l and then esc to revert to breadcrumbs. To permanently switch to text users have to use gconf-editor from a terminal. Note: gconf-editor has been removed from the menus. The key is.
    apps>nautilus> preferences> always_use_location_entry


    Minimize, Maximize and Close button placement.
    A decision has been taken to move the placement to the left. Mark Shuttleworth explained that this was because "something" is going to be placed in the right hand area in the next release. Moving the buttons now would help enable this change.
    [Update ]http://www.markshuttleworth.com/archives/333

    The buttons are in the old location on all default themes apart from Ambiance,Radiance and Dust, If you still want the Ambiance ,Radiance or Dust theme but with buttons on the right, choose one of those other themes and use the Customize button to achieve what you want. e.g.
    1. System > Preferences > Appearance
    2. Select the theme icon "New Wave"
    3. Click the button "Customize.."
    4. Select tab "Controls" and select "Ambiance"
    5. Select tab "Window border" and select "Ambiance"
    6. Select tab "Icons" and scroll down and select "Ubuntu-mono-dark"
    7. Select "Save Theme" to your choice.
    Using gconf-editor is not the right approach as this could bork future themes. This change makes it easier for themes to do interesting things with window borders. Unfortunately, if the wrong approach spreads, they won't be able to do that.


    Problem with Huawei and possibly other usb mobile broadband dongles.
    Please see this bug report and click the affects me button if you have this bug.
    Try this first
    Code:
    sudo apt-get install usb-modeswitch
    A fix is committed. https://bugs.launchpad.net/ubuntu/+s...ux/+bug/446146.
    Also fix/workaround here. https://bugs.launchpad.net/ubuntu/+s...ux/+bug/509547 See post #32


    Bootup/Plymouth.
    Users should experience a much faster boot however some users may experience problems with Plymouth after the nVidia graphics driver has been enabled. Users may experience plymouth using lower graphics resolution.
    https://bugs.launchpad.net/ubuntu/+s...th/+bug/551013

    Graphical solution : http://news.softpedia.com/news/How-t...4-140810.shtml

    Command line :
    (Some of the fixes put forward dont work for everyone.)
    One that works for nVidia and to try is this.
    Code:
    gksu gedit /etc/default/grub
    and add the line in BOLD.
    # The resolution used on graphical terminal
    # note that you can use only modes which your graphic card supports via VBE
    # you can see them in real GRUB with the command `vbeinfo'
    #GRUB_GFXMODE=640x480
    GRUB_GFXPAYLOAD_LINUX=1680x1050 Save the file and run
    Code:
    sudo update-grub
    The resolution chosen should be your monitors native resolution.

    Other graphics card users including nVidia may get a black screen with flashing cursor and then a very short duration plymouth.
    https://bugs.launchpad.net/ubuntu/+s...th/+bug/540801
    One fix for this is to create this file.
    Code:
    gksu gedit /etc/initramfs-tools/conf.d/splash
    and add this option FRAMEBUFFER=y, save the file.
    Then
    Code:
    sudo update-initramfs -u
    Plymouth now has a hard dependency on mountall thus trying to remove Plymouth would remove half the OS. The advice is, if you don't want a graphical boot then uninstall any plymouth themes.

    If the problem is a slow boot, and you have no floppy drive, disable the floppy in the bios. This has been reported as a fix to this.
    https://bugs.launchpad.net/ubuntu/+s...ks/+bug/539515 FIX Released.
    https://bugs.launchpad.net/ubuntu/+s...ks/+bug/551712

    If the problem is plymouth not displaying, and a black screen from grub to gdm, this could be due to graphics drivers needing to be loaded quicker. This is bugged.
    https://bugs.launchpad.net/ubuntu/+s...ux/+bug/539787

    Plymouth is installed with 2 themes by default you can install more via synaptic.
    To change themes this code is used.
    Code:
    sudo update-alternatives --config default.plymouth
    Java.
    Sun java has been deprecated. Openjdk is now the default, i.e installing ubuntu-restricted-extras with recommends will install openjdk and the icedtea plugin. Openjdk has been certified by Java SE Test Compatibility Kit (TCK) and is compatible with the Java(TM) SE 6 platform on the amd64 (x86_64) and i386 (ix86) architectures. However sun-java is in the partner repo.
    There's a bug regarding the icedtea plugin and certain applets.
    https://bugs.launchpad.net/ubuntu/+s...-6/+bug/551328.
    Not fixed yet. Workaround may be to create a new Firefox profile.


    Boot options hidden by default on Desktop and Netbook LIVECDs
    The Ubuntu 10.04 LTS Desktop and Netbook CDs feature a new boot interface that is non interactive by default.
    To configure advanced boot options, press any key at the first boot screen.


    Scrolling with ALPS Laptop Touchpads
    Various users who have ALPS touchpads have reported that scrolling no longer works in the final release. A bug report is already open on the case, and the current workaround is to run:
    Code:
    sudo rmmod psmouse
    sudo modprobe psmouse proto=imps
    If this works, you can make it permanent by putting:
    Code:
    options psmouse proto=imps
    At the bottom of the file /etc/modprobe.d/options


    Ubuntu shuts down after unplugging Laptop power cord
    A problem known with MSI wind and some Vostro users.

    Current workaround is to open gconf-editor and browse to:
    Code:
    /apps/gnome-power-manager/general
    And de-select the option use_time_for_policy

    There is no need to restart, just close the configuration editor.

    Re: Known Lucid Lynx issues/bugs with workarounds

    A lot of users are overwriting their windows boot sector due to a confusing message with the grub2 install. It says something like 'Choose where to install grub. If you are not sure select all partitions'. And this leads some to select their windows partition.

    NOTE: if you are reading this before you upgrade, the only place you should install grub is to the drive you are booting from. For most people it's /dev/sda . If you installed from within windows (a WUBI install), do not install the grub2 bootloader - leave all boxes unchecked.

    The fix and diagnosis is at: http://sourceforge.net/apps/mediawik...ms:Boot_Sector courtesy of meierfra.

    This is not the same as the bug that caused the re-release of certain iso's. That had to do with the windows not being listed in the grub menu. In this case, the windows option is listed but fails to boot.

    Re: Known Lucid Lynx issues/bugs with workarounds

    Another issue - when upgrading to 10.04 from a wubi install (not sure if it affects normal upgrades) it gets into a tight loop. What it says is 'Preparing memtest86+' and if you click on the terminal windows it just shows the line 'found linux image linux-2.6.xxxx' repeating.

    Anyway, if you hit CTRL+C it continues successfully. Some people have tried rebooting or canceling the install which leaves their ubuntu broken.

    Here's a link with a picture: http://ubuntuforums.org/showthread.php?t=1467754


    Looks like this is the launchpad bug for it: https://bugs.launchpad.net/ubuntu/ka...in/+bug/540579

    Edit: I can confirm I didn't get this with a normal (non-wubi) upgrade.

    Re: Known Lucid Lynx issues/bugs with workarounds

    We also have a common bug if you have not encountered it. FSCK hangs or crashes on bootup.

    Related bug reports:
    https://bugs.launchpad.net/ubuntu/+s...ll/+bug/571707
    https://bugs.launchpad.net/ubuntu/+s...th/+bug/572786

    Essentially if it hangs, it may finish in about 5 minutes or more. Sometimes hitting an arrow key around the 85% mark I believe helps it continue for some reason. This bug needs more investigation, but it will definitly bother many people. Just to test it, you can sudo touch /forcefsck and see if you have the problem on bootup. Thanks for making this post a sticky, keeping common bugs together for everyone to see.

    If Pitivi gives errors, and the gstreamer packages have been installed, reinstall pitivi from synaptic.

    Also, thanks for the gconf min-max-close syntax.

    Another, minor issue: the upgrade removed xscreensaver from my sister's computer. The fix, of course, is simple: use the package manager to reinstall it.
    Registered Linux user #470359.
    Any advice in this post is worth exactly what you paid for it.
    Remember, folks, I don't use Ubuntu, I just support it.

    Re: Known Lucid Lynx issues/bugs with workarounds

    Hi, there is a rather permanent problem with the propietary ati drivers. Maximizing and unminimizing is terribly slow with compiz enabled. There are several workarounds, however. You could either try the no-backfill xserver, the back-clear patch or enable Direct2D.

    Direct2D can be enabled with the following steps:

    1. backup your current xorg.conf

    ~$ cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak


    2. delete the contents of xorg.conf

    3. let aticonfig make an initial configuration:

    ~$ sudo aticonfig --initial

    4. then enable Direct2D:

    ~$ sudo aticonfig --set-pcs-str=DDX,Direct2DAccel,TRUE

    I personally prefer the backclear patch as I noticed that although the maximizing issue is reolved with Direct2D, scrolling in for example emacs becomes totally sluggish. You can find more information on the backclear patch here:

    log out and in and enjoy your fancy desktop. hope it helps.
