Title says everything. Here is output of Boot info script: http://paste.ubuntu.com/1169338/

sudo os-prober returns only Windows partition:

sudo os-prober
/dev/sda2:Windows 7 (loader):Windows:chain

If I manually mount Arch Linux partition with Nautilus, sudo os-prober returns Windows and also Arch Linux partition:

sudo os-prober 
/dev/sda2:Windows 7 (loader):Windows:chain
/dev/sda6::Arch:linux

If os-prober don't find Arch Linux partition, Arch Linux don't show on the Grub2, so everytime kernel in Ubuntu is updated I have to manually mount Arch Linux partition and run sudo update-grub. Does anyone have any idea how to solve this problem?

P.S.: I use Ubuntu 12.04 LTS

I am trying to develop some program in QT with QT SDK. Yesterday I was reading about Unity Launcher API on official ubuntu website. But there is example only for Vala and python. Is possible to use Unity Launcher API(quicklists, counters, and progress bars) with C++ language and if it's possible, please post an example.

Laptop #1 is connected to the router via WiFi. Laptop #2 is too far away from router to be able to connect to them. I can create a access point or Ad-hoc if I am connected to the router via wired network. But Laptop #1 is not connected to router via cable, but via WiFi. Is it somehow possible to create acces point or Ad-hoc on computer, which is connected to router via Wireless? Any help is appreciated.

I want to install Ubuntu 10.04.2 on laptop, but first time I run Ubuntu live CD it runs perfect, but when a rebooted the live CD don't want to boot anymore. Live CD sometimes gives kernel panic(Kernel panic - not syncing attempted to kill init!), sometimes it goes to busybox. I also tried with acpi=off option, but still kernel panics or dropping to busybox. Live CD is ok, because I already installed Ubuntu on some computer from the same CD.

I tried with Ubuntu 11.04 live CD, but this version also gives kernel panics.

I also tested memory with memtest and computer past the test without errors.

Because the laptot have only 512 MB of RAM I tried to install Lubuntu 10.04, but when I boot Lubuntu from live CD it gives me kernel panic((process:289): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0), Num Lock light is blinking)

I sometimes get errors like Authentication failure, Input/Output error or

SQUASHFS error: Unable to read data cache entry [c4d70c8]

SQUASHFS error: Unable to read page, block c4d70c8, size e046

The laptop is Acer Aspire 5100 and it has:

• AMD Turion 64 (2.0 GHz, 512KB L2 cache)
• ATI Mobility Radeon X1300 128MB
• 60GB PATA HDD
• 512MB DDR2
• other things, like WLAN, bluetooth and so on

This laptop have Windows XP installed, but they are slow as hell(so slow, that they are impossible for normal use), so I want to install Ubuntu or Lubuntu, but it gives me various errors, while I am attempting to at least run live CD. Should I try with live USB?

Any help is appreciated. :)

UPDATE: I also tried Fedora 15(with Gnome shell) right now and it boots. Why the hell Ubuntu don't want to boot?

UPDATE2: It looks like the Ubuntu 10.04.2, Ubuntu 11.04 and Lubuntu 10.04 CDs are damagaed, acording to CD files check. But before I used this CDs on various computers, they just works. There must be something wrong with DVD-ROM on this laptop, because those CDs were OK before I tried it on this laptop. I am now downloading Ubuntu 10.04.2 iso image and I will make a liveUSB and then I will post results.

This question is similar to this: How do I limit internet bandwidth?. But the wondershaper and trickle cannot limit internet bandwidth for already started applications. So, how can I limit internet bandwidth for already started applications(but only for one application, not for whole system)? :)

I open .avi video with Avidemux and I set Video format to MPEG-4 AVC(under Configure, Bitrate tab I choose "Single Pass - Bitrate (Average)" and Target bitrate to 256 kb/s, under Filters I choose MPlayer resize to 480x360 and I also add a subtitles) audio format to AAC (Faac)(Under Configure, I choose Bitrate 96) and format to MP4(like a image below). When Avidemux convert video to .mp4 format I can play the file on my copmuter, but on my phone I can't. When I want to play it on my phone with native video player, it just show the error something like "Can't play this video". So the question is how to convert .avi video to .mp4 with Avidemux(because I want to have subtitles inside movie) to be playable with android phone(Android version 2.3.4) with native player.

Any help will be highly appreciated. :)

I have installed Ubuntu 11.04 on my laptop. And now I wanted to try Xubuntu and Lubuntu(both version 11.04). And when I installed Xubuntu and Lubuntu, grub2 recognize them both as Ubuntu instead of Xubuntu and Lubuntu. Any help is appreciated.

Is there any option in brasero to disable the checksum feature in brasero? It slows down the burning.

Is there any program that shows all hardware (e.g. Graphic card NVIDIA GeForce 9600GT, Network card, and so on) on your computer?
