Notebook: Dell INSPIRON 1564. There was no such problem in Ubuntu 11.04. Don't upgrade to 12.10, you will encounter ugly interface problem (see here).
Noticed from here: askubuntu, a method was proposed, which was to modify a line in /etc/default/grub
into
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi=Linux"And then update and reboot
sudo update-grub sudo reboot
Although I tried the same, I don't confirm this will definitely work. My experience is, if you tap slowly one at a time until it changes the brightness and show the notification, then proceed, it will be okay. If you are stuck in such freezing state, any keyboard combo can't save you out.
That is what I wanted to do. Ubuntu didn't save (or the video driver) the last-time configuration of brightness. (link)
The solution, I too confirm, is to add a local script to be executed on reboot. Here is the excerpt.
sudo vi /etc/rc.local
Add the following due to your folders under /sys/class/backlight
(you might need play around with it)
echo 0 > /sys/class/backlight/acpi_video0/brightness exit 0
My machine uses a default video driver (non-proprietary) and the video card ATI RV710.
grep "foo\|bar" grep -E "foo|bar" egrep "foo|bar" grep -e foo -e bar
grep foo | grep bar
grep -v foo
This app is basically a link to a website.
Create manifest.json
with the following content
{ "name": "BBC News", "description": "BBC World News", "version": "1", "manifest_version": 2, "icons": { "128": "bbc-icon-128.png" }, "app": { "urls":[ "http://www.bbc.com/news" ], "launch": { "web_url": "http://www.bbc.com/news" } } }
I got this icon,
At chrome://extensions/
, turn on Developer Mode, and click Load unpacked extension, locate the folder, that's it!

If lucky,
CTRL + ALT + DEL
If still lucky, call a terminal
CTRL + ALT + F1/.../F5
If not so lucky,
ALT + SysRq (PrtScr) + K
Ah, everything fails. Here is the magic wand for Linux kernel
CTRL + ALT + SysRq (PrtScr)
That is to hold Ctrl+Alt, tap SysRq, then type in order:
REISUB
which is BUSIER in reverse order.
I run into a period that I have to give up my hard disk (hardware failing).
Download OS ISO from the links provided in Windows Community (search "windows 7 home / professional iso etc.")

You know how. :) I downloaded Home Premium version (didn't find an Italian version which I was using).

Windows 7 USB/DVD Download Tool
is an open project from Microsoft that allows you to burn to USB easily. Try it, it is neat.
One thing needs to mention. you might see setup was unable to create a new system partition...
. Windows 7 seems to find difficulty in identifying the primary drive. In this case, configure your booting priority from BIOS so that your HDD is the first. Then choose from boot options for starting from USB. Hope this helps.
It is said to be working (confirmed now by me) if you have an OEM (most of us do) product key (on your COA label at the back, needed at installation). After installation, you will have three days to activate it. Go to Control Panel > System and Security > System, under Windows Activation, call the toll-free number shown, enter the numbers in groups, then you will receive the same amount of numbers to activate the system. It is indeed working!
An OEM product key is said to be reusable for the same machine. I replaced my hard disk with a new one, I think this doesn't make my notebook a new one according to Microsoft. The fact is I did have installed the English Win 7 Home Premium with my Italian Home Premium Key.
I guess Microsoft is encouraging customers to solve problems on their own so as to get rid of lots of unnecessary labor. And you are able to legally download their whole system (though not emphasized officially)!

Substitute foo
in file names to bar
:
for f in *; do mv $f ${f/foo/bar} done
Prefix all .jpg
files with foo
and a counter:
i=1 for f in *.jpg; do mv $f 'foo-'$i'.jpg' i=`expr $i + 1` done
Notice spaces in expr
can not be omitted.
You can start a MINGW32 shell command line from git cmd under Windows.
i=0;for f in *.jpg; do mv $f $i'.jpg'; i=`expr $i + 1`; done
