To get a GNU/Linux to reboot properly and not hang in the final step, you need to pass another parameter to the kernel. You need to pass reboot=pci to Linux.

Currently, Debian and Debian-derivatives such as Ubuntu tend to use Grub2 as the bootloader, by default. You need to:

• edit the /etc/default/grub configuration file, as root, and using your favorite editor
• find line that looks similar to GRUB_CMDLINE_LINUX=”"
• if it contained anything inside quotes, don’t delete those commands!
• into the quotes, add reboot=pci but do not delete existing text
• back in command line, run update-grub as root user

It should now work flawlessly!

Your X.org misbehaves? You don’t like what’s done in Ubuntu? To forcibly restart Xorg, you have two options:

In /etc/init.d/xorg.conf:

Section “ServerFlags”
Option “DontZap” “false”
EndSection

or use RightAlt+PrintScreen+K.

Imate problema s preglednikom Opera dok ste na Ubuntu, Debian ili na drugoj GNU/Linux distribuciji?
Simptomi su stisnut “mali” tekst, problemi s web stranicama koje nemate na drugim OSovima i browserima i accountima, ili problemi sa zaokruživanjem u Javascriptu.
Problem, a i lijek, je jednostavan.

Problem je u tome što ste si postavili hrvatski jezik. Najlakše rješenje je postaviti OS natrag na engleski jezik. Tehničko objašnjenje slijedi u nastavku na engleskom jeziku.

After a short explanation for Croatian users, here’s what the fuss is all about. If you set your locale to Croatian (set your environment variable LANG to value “hr_HR.UTF-8″) you’ll experience issues such as:

• condensed text with incorrect line spacing (demo: Wikipedia)
• incorrect Javascript rounding (demo)
• problem possibly occuring only on a single account, but cleaning most configs doesn’t help

Solutions (pick one):

• set your locale to English through the GUI
• set the environment variable LANG to en_US.UTF-8 or just en_US
• set the environment variable LC_NUMERIC to en_US.UTF-8 or just en_US

Some demo pics:

Wrong rendering: locale set to Croatian

Correct rendering: locale set to English; setting LC_NUMERIC is sufficient

(Yes, they were taken on different accounts. Yes, I have tested in case )

Reproducing:

• Launch terminal
• Install Croatian locale. Under Debian, install package locales and then, as root, dpkg-reconfigure locales and mark hr_HR.UTF-8; there’s no need to set it as system default afterwards
• Run Opera as regular user from Terminal: LANG=hr_HR.UTF-8 opera
• Visit one of these URLs:
• http://drupal.org/node/333967 (text invisible)
• http://daiwai.de/test/jsdecimals.html (rounding to 28 instead of 28.45)
• http://en.wikipedia.org/ (text extremely condensed)

Where does this bug apply (at least):

• Opera 9.64 build 2480 from official repositories
• Debian GNU/Linux
• Applies to both statically and dynamically linked builds

What this bug IS related to:

• your locale being set to hr_HR[.UTF-8]
• probably setting LC_NUMERIC to hr_HR[.UTF-8] is sufficient

What this bug is NOT related to:

• scim-qtimm – similar bug was occuring few years ago to users who had scim-qtimm installed under Ubuntu 6.06
• your Opera GUI language

A friend pointed this out to me:
http://kb.mozillazine.org/Browser.backspace_action

In short, if you’re a GNU/Linux user of Firefox (e.g. Firefox on Ubuntu and Iceweasel on Debian) you may want to get backspace to actually go back one page, like many browsers do (did?):

1. In addressbar, type about:config
2. If asked, confirm you want to change settings
3. In search, type browser.backspace_action
4. Set the value of browser.backspace_action to 0 (that is zero, not letter O) Zero is Windows default and makes pressing backspace go back in history; One is old Linux default and scrolls page up; Two is new Linux default and, like any other integer, simply unmaps the backspace key.

Now, enjoy pressing backspace to go back!
