Sudo runs the command following as another user (root by default)

So you open a terminal, then in that window, you write (or copy/paste)

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4E9CFF4E

which will run apt-key as root.

(If you're familiar with the Windows command line, the equivalent command would be something like runas /user:administrator "apt-get adv....")

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!

I made a shortcut to a program on the desktop, picked an icon for it and it looks and works great. Even shows the right icon in the dock. But when i drag the icon to the launcher, it reverts back to the jack in he box looking spring icon.

edit: figured it out

I created this file as ~/.local/share/applications/sublime.desktop

code:

[Desktop Entry]
Name=Sublime Text 2
Comment=Sublime Text
Exec="/home/robert/Downloads/Sublime Text 2/sublime_text" %F
MimeType=text/plain;
Terminal=false
Type=Application
Icon=sublime_text.png
Categories=GNOME;GTK;Utility;TextEditor;Development;Utility;

Then I copied the icone file included with the app to /usr/share/pixmaps/

Okay super, I'll give that a shot tomorrow. Thanks for the duh in your face answer. I/we are still extremely new at this.

I assume Sudo is the default terminal emulator in Ubuntu? I'd check but the computer isn't in front of me.

You don't need to mess around in the terminal to add repositories to ubuntu, in fact I recommend you don't. This page lists multiple ways to add repositories to ubuntu. Use the Ubuntu Software Center method if you're using the standard ubuntu install.

You shouldn't have to do anything special. I did it the other day to make sure 12.04 worked on my MBA and it booted off USB just fine.

PleasantDilemma: Dec 5, 2006; The Last Hope for Peace

anyone here have experience with Ubuntu cloud? I was playing around with the cloud live CD last night but having some issues. in the control panel it wouldn't create any volumes. I assume that's because it was running off USB. I was able to load the cirros image, but couldn't SSH into it from another computer in my LAN even though it was set as public.
is there an easy way to just install that live image, or do I have to install server edition on several computers and choose the MAAS option?

I want to shut down my computer with a cron job, but it doesn't work. shutdown -h, shutdown -P and shutdown -r all work fine when run in a console, but in a cron job it just shows the ubuntu shutdown screen (and suspends when using -h or -P) but never actually powers down or restarts.

I tried shutdown -r now in a cronjob and I got the usual broadcast message and it disconnected my ssh session, but did not actually reboot.

Since nothing happened, I reopened the ssh session and ran shutdown -r now, and it worked beautfully. :confused:

I used to use btnx on prior versions of Ubuntu, to map Home and End to extra mouse buttons. Now, btnx is apparently deprecated, I can't get the old source to compile cleanly, and I can't find any newer alternatives for 12.04.

Is there something which can easily map a keystroke to a mouse button, like btnx?

EDIT: I got it working by going to my 11.10 backup, and just copying the btnx and btnx-config binaries, and the config file btnx-config.glade. It is working perfectly.

Well, I don't really know what causes it, but I was able to make an acceptable solution.

My original try was

code:

0 1 * * * /usr/bin/setwake_to_630_and_shutdown.sh

That script then runs

code:

/usr/bin/setwakeup.sh `date --date "today 6:30" +%s`
/sbin/shutdown -h +5 "sleeping until 6:30, use shutdown -c to cancel"

setwakeup.sh:

code:

echo 0 > /sys/class/rtc/rtc0/wakealarm #this clears your alarm.
echo $1 > /sys/class/rtc/rtc0/wakealarm #this writes your alarm

Maybe I went too deep with my scrips or something. Anyway, the following crontab seems to work just fine:

code:

0 1 * * * /usr/bin/staticwakeup.sh
0 1 * * * /sbin/shutdown -P +5 "powering down until mornining, use shutdown -c to cancel"

where staticwakeup.sh contains

code:

#!/bin/sh
TIME=`date --date "today 6:30" +%s`

echo 0 > /sys/class/rtc/rtc0/wakealarm #this clears your alarm.
echo $TIME > /sys/class/rtc/rtc0/wakealarm #this writes your alarm

A little less fancy (I guess), but does the same thing

edit: Except now that it's the next day, I saw that it didn't work any better. :mad:

Maybe it's the length of the sleep or the countdown to it. With a 5 minute sleep and 1 minute warning to shutdown, it works the way I want to. ~5 hours shotdown and 5 minute warning and the computer does power down, but when it comes back up (or rather when I wake up and turn the tv back on) it's in the shoutdown screen. i.e. this screen: http://1.bp.blogspot.com/_4B7ZWQHqMpk/TMcEEwqP88I/AAAAAAAAAEc/uVUzQyc32Ik/s1600/boot1.png

I gave up on Ubuntu after 11.04 (mostly because of Unity) but I've been trying the new release on a VM and it seems like they solved most of the problems related to releasing Unity before it was ready for production.

So, I'm thinking about installing Ubuntu again. I have one question though, is there anything similar to Photoshop that is not GIMP? I used to use a Windows VM just for Photoshop and I'd like to avoid that this time.

I'd say it depends on what you're trying to do. My father uses inkscape in production, but that's just to create logos for his products. There's also LibreOffice Draw, although I can't attest to its quality.

I do a lot of things with it, from making website mockups (including graphical resources like logos, backgrounds, icons, etc) to perfectly ordinary photo editing.

Lately I have been making mockups directly into HTML but I still need something to make things to fill up that mockup.

vvvv
Last time I tried that, Photoshop ran actually slower than on a VM and it had some graphical issues. :v:

So there's a fantastic bug in 12.04 that affects laptops. The Fn+F1 shortcut on Dell computers no longer functions properly. There's a patch, but I have no idea how to use the patch command. The patch is something that can be applied to an install right, it's not for the source code?

The way to apply a patch is actually quite involved -- you have to get the package source, apply the patch to that, rebuild the package, and then install the resulting binary packages.

There's Krita which seems pretty powerful, though I haven't tried it myself yet.

There's also MyPaint which seems pretty solid (and it starts up quicker than GIMP).

I'm having a wireless connection problem since I've upgraded to 12.04. I'm able to connect to a wireless but not to the internet. Other devices are able to connect successfully with internet to the same connections (another laptop and my android phone). What's weird is I'm able to connect to the open ATT wireless connections. I was briefly out of the country when it stopped working. I've reset the country code back to the US using iw.

I don't want to make Apport ignore the crash (which is an option), I just want it to be sent automatically.

Speaking of mice: Can anyone recommend a touchpad manager that has the same functionality as Synaptiks but, you know, actually loving works?

Master_Odin: Apr 15, 2010; My spear never misses its mark...

ladies

when using gnome classic, is there a way to have all three menu options at the top (which are Applications/Places/Admin. Admin seems to be missing which then makes it slightly harder to get rid of.

Additionally, it seems like Alt+Tab is broken as well. (I installed gnome by using sudo apt-get install gnome-shell. should I remove it/install gnome through the fallback method?)

I wanted away from unity because when using steam through playonlinux (which uses WINE), it would create a black box to the lower right of the window as well as eventually causing the bar on the top and left sides of the screen to disappear completely (though I could still select icons/menu tabs). I guess I'd settle for fixing unity as it does bootup faster than gnome.

You mean the connection to the machine you just put in sleep mode? Yeah, that's how suspend works. It takes down pretty much everything except what's needed to keep the RAM going. That means programs won't do anything while it's sleeping, and the network cards are powered down.

If you want to decrease power consumption, make sure you have cpufreq and laptop_mode installed. The basic settings should be enough to decrease it quite a lot, and they'll be active immediately after installation IIRC (well, assuming your hardware has support for that kind of stuff).

I'm using a Macbook 2,1; dual-booting OSX and Xubuntu 12.04. The laptop seems to have a lot of trouble connecting to my wireless network. Xubuntu reports the connection as successful and a great signal, but I can hardly do a thing with it. There is a lot of latency and it takes forever to actually load anything. I'm not sure what kind of diagnostics checks I can do here, so I was hoping someone here could give me a hand getting this to work.

For the record, wireless works fine in OSX.

EDIT: Guess I should mention that my other computer (Toshiba Satellite running Windows 7) connects without a problem as well. It's just Linux...

I've had problems on two computers now where the installer wrote GRUB to the USB drive rather than the hard drive. It's not too hard to fix from a live CD/USB, but it seems like the installer should be more intelligent.
