After a power failure, I lost sound on every software (vlc, firefox, totem, ...) except for rhythmbox. The sound displayed when ubuntu starts worked too.
I tried rebooting, repairing the filesystem (no errors found), but it's still the same.
I am developing an app using Quickly and it has a few dependencies like 'python-xdg' for example.
When I do quickly share on a computer that has Ubuntu 12.04 without Pre-released updates (precise-proposed), those dependencies are well reflected in ./debian/control. But when I launch this command...
From the looks of the questions, it appears they would have been better off just writing a tutorial on how to package for Debian once the Quickly/Glade/PyGTK part was over.
And it's the "somewhere" that is the problem. I don't mind them pushing Quickly, I just mind them not bringing up say, Qt/roll-your-own-python/C++/Vala/$LANGUAGE. But, that's their choice, and I respect it. I disagree, but I respect it. Their competition, their rules and choices.
Well not really, but the BIG PR push has been for Quickly. Apart from George Edison, the non-quickly questions for app showdown can be counted on one hand. The odd dbus question, etc.

@izx A number of people have had this problem. Your solution seems obvious, but I feel like I've glossed over it and gone to more complex suggestions like changing GRUB's video mode. I'm very glad to see your answer. Do you know if this is the first time someone has asked this question explicitly?
Upon booting, when I should see the GRUB menu, my monitor simply says: "No optimum mode. Recommended mode: 1600*1200". If I wait for a short while, Ubuntu starts to boot and it reaches the desktop.
So I guess there is no video signal during that time, there's the grub menu but I cant see it and...
@EliahKagan I was thinking about that, and I'd go with that one. I'll edit to add a mention of dual-boot somewhere, that's the problem long-winded German lady had; that's the other common circumstance when you'd see the Grub menu by default.
See, syslinux (livecd bootloader) has this really nice hardware-info module. Perhaps Ubuntu should use it and automatically enable nomodeset when an Nvidia graphics card is detected.
For those who missed it, here's Linus on Nvidia (time-limited edition)
I installed 12.04, patched up to the latest, but transfers to USB 2.0 thumb drive take too long and consumes a lot of CPU. The same drive works fine on Windows using the same USB port, though.

is there a way to make the copy progress bar show real progress? http://askubuntu.com/questions/161393/is-there-a-way-to-make-the-copy-progress-bar-show-real-progress?atw=1 #nautilus
@izx when someone is so obviously irritated, it makes wanting to help them hard. also a warning on refresh rate, a weird monitor type, and a nvidia 2d/3d speaks to a relatively ancient video card (where blob glitches on 3d) or a new one with optimus. just too many variables for a one sitting answer imo
I think the best aproach would have being wiping out grub and letting him get back to windows, and take some time to figure out how to restore grub and drivers later. Although not relly on topic.. sortof.
with the "bizarre squashed screen" it sort of makes me wonder if it's his monitor doing something weird scaling its video to it's initial resolution...maybe up/down arrowing to get the grub menu to pause and power cycling the monitor to get it to probe again (long-shot i know)
here's how I messed up my ubuntu, I wanted to change file permissions of '/usr' folder and did by taking root privilege
sudo -i
I changed the file permission and logged back to my home user, but now I am not able to use 'sudo' command, I tried to change the permissions back by using chown a...
I enetered chmod -R 777 /usr/bin and now sudo is not working.
it is giving error that 'sudo must be setuid root'.
On looking into google few advice said that chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
On entering chown root:root /usr/bin/sudo it is showing 'opened in readonly mode'...
There needs to be a canonical Q/A on using a LiveCD to simply restore the stock permissions of critical system files/folders. @aking1012: not just chmod but chmod -R!?
@izx You can do that by running chmod with pkexec, too. Just like you don't actually need to reboot to fix broken sudoers, you don't actually need to reboot to change permissions (provided you are an administrator, and PolicyKit is installed).
If you read to the end of that loooong post (and I only know because I remember when that part was close to the beginning ;) she's running on an ancient GeF 6150 with an ancient 15" LCD. Jockey drivers are incompat, and the textmode fix worked, but XP won't boot. And yes, too big a data dump to process in one question, that too non-interactively.
@izx Of course, it's possible to break bothsudo and PolicyKit (or just the pkexec executable), plus you might make yourself not-an-administrator. Plus, PolicyKit is generally not present on Ubuntu Server systems. So booting from live media to fix permissions or sudoers is also a very important thing to be able to do.
@EliahKagan, ah yes. If you havent already you should do a tutorial type QA on using pkexec.
Anyone purporting to administrate a CLI server who is upto such shenanigans should stick to IIS
Is there an official "welcome, switchers" page/portal that advises people who want to try Ubuntu for the very first time ever on what to do? Eg on Windows, try Wubi first NOT dual-boot so that you still have Win as a backup? Etc.
boo @ wubi first line. virtualbox or bust and a note that you will have trouble migrating (redhat pulled their vdi v2p and p2v project...it was in the public domain once).
There are two general ways to run applications graphically as root (or, more generally, as another user). Programs like gksu, gksudo, and kdesudo are graphical frontends for sudo. In contrast, pkexec is a graphical frontend for PolicyKit.
When manually running programs as root (or as another, no...
@aking1012 Virtualization is voodoo for most. Wubi is great to "try" Ubuntu, IMHO. I agree that there needs to be a disclaimer NOT to make it your main system or use it heavily unless you know of the caveats; and better to install it dual-boot or solo if you decide to "buy" after you "try"....
@aking1012 Wow...I know I did it in alsa/esound way back when...don't know that much about the pulseaudio source/sink business, but yes, intuitively you should be able to...
I'd ask a question -- the explosion in HDMI/HomeTheater means there are a lot of pavucontrol/pa gurus around...
anyone that rage-quits linux should donated their aged hardware to an AU/Ubuntu user-group so someone could "I can touch the keyboard" troubleshoot it. (I've even refused friends when I can't touch the keyboard)
I learned that the hard way over the years, telling folks "Sorry, no can help remotely. If you want that, ask me what hardware/sw to buy the next time you upgrade and then I can try to help." (both Win/Lin)
Samsung's Kies does not work with Linux or Ubuntu. I have Ubuntu 12.04 64-bit and I have been able to use Air Kies and my USB cable to connect to my Samsung Exhibit II 4G phone (not the same as the Samsung Exhibit S II or Exhibit II S phone! No S!!) and access all the information on it. However, ...
What, if anything, is the difference between this command:
sudo apt-get clean
And this command:
sudo apt-get clean all
On my Lubuntu 12.04 system, simulating these commands reveals their behavior to be exactly the same:
ek@Apok:~$ apt-get -s clean
NOTE: This is only a simulation!

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the commands below.
sudo apt-get autoremove
sudo apt-get clean all
sudo apt-get update
Once you do that, then you can run: sudo apt-get install gnome-shell
i still can't boot into Ubuntu. It starts loading with the Ubuntu logo and the small dots underneath but after a few minutes the dots would stop moving and stay that way for almost an hour! I can move the mouse pointer but that's it. nothing happens. I've already run fsck on the Ubuntu root partition and everything was fixed.
i did that already, it would suddenly stop loading on boot. I was thinking maybe it was because of the NTFS partitions. So I wanted to see if there's a way to check ntfs partitions while running Ubuntu liveCD
no i said i was able to boot to a liveCD, because last night when I was here I was asking advice about not being able to boot with a liveCD, since I was using liveUSB you told me to burn it to a CD-R
it just taking a long time to boot and I simply cannot wait for a very long time for it to finally get to the desktop, last night I've waited for almost an hour but still I didn't get to the desktop
I even just let it on and I went to sleep when I woke up it was still loading....don't know what is wrong...so I'm not sure if Ubuntu can't boot or what....I might as well run on LiveCD than wait for hours
Boot into text mode then. Press e as jokerdino explained at grub boot menu. Then replace quiet splash at the end with the word text. Press ctrl-x to boot.
Just want to suggest that it would be great to see a Responsible Web Server Module built into the Layered(ring) security design of Linux. We hear all the time about Security, Portabilty, Usabilty, Maintainabilty, etc of Systems. Which is essential for good design. But the main reason being withou...

This is gonna be fun: Ubuntu countdown says App Showdown end is sometime after 23:59 UTC July 9; dpm says end is 00:01 UTC July 9, and a Google Plus event somewhere says end is 12:00 UTC or something....
on the other one that asked why would you install yum, i thought about weighing in with something like "to get rpm or srpm to feed to alien" and yes...i take your point
@aking1012 Thx. Agreed with ^^^; it's often a good idea to divine OP's intentions when presented with such questions, but I think it's best for OP to reply (if at all) rather than create a meta-discussion.
I would stay away from multiple package managers. The only viable use case I could see for installing yum would be to get rpm or srpm packages to feed to alien in a more streamlined fashion without resorting to something like rpmbone.
meant to say that 7z x blah.deb gives you nice filesystem.tar and control.tar archives (on Linux); 7z on Windows will gobble control info and just give you a filesystem.tar
Well...while you CAN install them, the target of AU is to provide useful/meaninful answers as community support. As such, we stay away from highly custom things that will in all probability break stuff *e.g. custom kernels, mixing package managers, and from source installation*
agreed. and we go back to something like my 7 star comment. if you have to ask, maybe you shouldn't be doing it. it'ld be like asking how to change a tire then wanting to rebuild a car engine
@aking1012 Agreed, I give up on that Q though. As Jorge was telling me earlier today, just gotta shrug at these things and move on, if you get embroiled in things you won't survive.
If they'ld post a page-link on the developer portal to probable finalists it might get through to the media powers of the inter-tubes
I wonder if @Agmenor ever finished his YT download app...so many UI difficulties he had, but didn't want to do the worker code first... cli app with all the worker classes first, then snap-on a UI was always my idea of a design pattern
If I were a naive-ish contestant, I might be pissed at this if I'd relied on it (countdown clock on AppShowdown page showed ~24 more hours). "Until July 9th" is very ambiguous, and "00:01 UTC $day+1 " is never a good deadline time, "23:59 UTC $day" is...

Here's an even simpler answer. All it requires is picking up the phone:
Canonical Support
I enetered chmod -R 777 /usr/bin and now sudo is not working.
it is giving error that 'sudo must be setuid root'.
On looking into google few advice said that chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
On entering chown root:root /usr/bin/sudo it is showing 'opened in readonly mode'...
It seems a bit of a meta tag to me.
But I can also see some desire to keep it (I have used it myself!)
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the commands below.
sudo apt-get autoremove
sudo apt-get clean all
sudo apt-get update
