FAQ - Workarounds

Introduction

Some of the annoying little bugs (paper cuts) in Lubuntu are on the list of things to be sorted out. Many have been addressed in later releases of Lubuntu and backported to earlier versions, but some paper-cuts persist. As most of these involve the use of the command line, if you are new to it, please do have a read of LXterminal. When you see

some instructions

That means you need to type them into LXterminal.

If you cannot find your issue listed here, please also check Guides for additional information.

Lubuntu Software Center not working

[Ed.: refers to non-released version of Lubuntu] This shows itself as when you select Lubuntu Software Center from the menu, nothing happens. To confirm that the problem you are having is the known problem, please carry out the following.

lubuntu-software-center

If you get a lot of errors regarding python then please carry out the following

rm -r ~/.config/lsc

That will force Lubuntu Software Center to rebuild next time you start it from the menu (it may take a little while to rebuild).

Problems with Abiword

This is a known bug. There is a workaround available from here.

LXPanel disappeared and after lauching lxpanel again, it looks ugly.

lxpanel --profile Lubuntu

Note: The command above is case sensitive!

When clicking in Chromium "Show in Folder" it spawns a new tab that shows only directory listing

gksudo leafpad /usr/bin/xdg-open

replace following lines in the end

    generic)
    open_generic "$url"
    ;;

with lines:

    generic)
    open_lxde "$url"
    ;;

After upgrade my keyboard layout changed

gksudo leafpad /etc/default/keyboard

replace

XKBMODEL="a4techKB21"
XKBLAYOUT="us,af"
XKBVARIANT=""
XKBOPTIONS=""

to

XKBMODEL="a4techKB21"
XKBLAYOUT="fi"
XKBVARIANT=""
XKBOPTIONS="terminate:ctrl_alt_bksp"

replace fi with your desired language, de,uk,it, you name it.

and then reboot your computer, as restarting udev service doesn't change it.

sudo reboot

Entire disk with encryption doesn't prompt for disk password

If you install LVM entire disk encryption, you may encounter the bug where you are not prompted for your password on bootup. Without this password, the system cannot decrypt your drive, and will not continue booting. This is only a problem for certian graphics cards.

Workarounds for this bug:

1) When you land at the blank screen (it is waiting for your LVM encryption password) just type your password. Alternatively, hit one of the up/down arrow keys to get to the GUI and enter your password (you will need to hit backspace twice to remove the two characters that were put in by the one arrow key press)

2) Edit your /boot/grub/grub.cfg file. In the menu entry for the kernel you wish to boot, add the text "plymouth:force-drm" (without the quotes) to the end of the line that starts with "linux /boot/vmzlinux-3.2.....". If you do this workaround, you will need to re-apply this fix anytime the kernel package is updated or grub is otherwise modified as the file is completely re-written each time.

3) Use the un-modified kernel. Read: https://wiki.ubuntu.com/KernelMainlineBuilds to manually download a mainline kernel and install on your system.

Taskbar or LxPanel Background is the wrong color

If you don't set the opacity of LxPanel, in the appearance tab (under LxPanel Settings) It doesn't look right. On the color chooser, you can set the color to non-transparent.
