Adding user kev to group root
Done.

$ cat /etc/sudoers
cat: /etc/sudoers: Permission denied

After adding myself(kev) to group root, I still cannot read /etc/sudoers.

I don't know why. Thanks for your help.

Update Manger has frozen for about 60min when downloading flashplugin-installer.
And the Cancel button of Applying Changes dialog is disabled.
When I click the top-left x, it doesn't response.
How to cancel downloading flashplugin-installer?

When I start gvim:

$ date; /usr/bin/gvim; date
Tue May 29 10:45:45 CST 2012

** (gvim:6030): WARNING **: Unable to create Ubuntu Menu Proxy: Timeout was reached
Tue May 29 10:46:11 CST 2012

To stop ubuntu menu proxy:

export UBUNTU_MENUPROXY=0

And test it again:

$ date; /usr/bin/gvim; date
Tue May 29 10:46:47 CST 2012
Tue May 29 10:47:13 CST 2012

No warning. But it still takes 26 seconds to start gvim.

Why it's so slow? Is there any season to make it happen (both 26 sec)?

Currently, I use:

alias gvim='gvim -f'

But I cannot detach from shell anymore.
Hope Ubuntu developer fix this problem as soon as possible.

I have both Windows XP and Ubuntu installed.
I want to set Ubuntu as my default system when boot the machine.
I don't want to press Down+Enter every time.

I am using Wubi.

Original boot.ini:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
C:\wubildr.mbr = "Ubuntu"

Modified boot.ini:

[boot loader]
timeout=30
default=C:\wubildr.mbr
[operating systems]
C:\wubildr.mbr = "Ubuntu"
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

But nothing changed.

Firefox constantly keep moving platformHTMLBindings.xml when it upgrade.
I want to replace it to support vi key-bindings. But I cannot find it any more.

sudo find / -name platformHTMLBindings.xml -o -name toolkit.jar -o -name omni.jar

Thanks for your help.

Edit:

I finally found it. It's called omni.ja now.

This is my editing to platformHTMLBindings.xml:

  <binding id="browser">
    <handlers>
      <handler event="keypress" key=" " modifiers="shift" command="cmd_scrollPageUp" />
      <handler event="keypress" key=" " command="cmd_scrollPageDown" />

      <handler event="keypress" key="k" command="cmd_scrollLineUp" />
      <handler event="keypress" key="j" command="cmd_scrollLineDown" />
      <handler event="keypress" key="h" command="cmd_scrollLeft" />
      <handler event="keypress" key="l" command="cmd_scrollRight" />

After Editing, I restart firefox, and clear the cache.
chrome://global/content/platformHTMLBindings.xml is correct.
But the j/k/h/l shortcuts didn't work.
