• Not able to create screenshot of when menu is active [closed]

  - by gotqn

  Possible Duplicate: Screenshot of active window doesn’t work I am using Ubuntu 12.04 and I am searching for a program that will let me to do screenshot of my menus too. Also, it will be very useful if I am able to "cut" only part of the new screenshot and save it as a new image. At this moment, when a menu is shown (for example I click on my clock and the calendar is shown) the "print screen" button is not working. This happens to with applications launchers menus in the left navigation panel. On windows I am using Gadwin Pro. Is there any alternative on Linux?

• Low-res emacs24 icon in application switcher 12.10

  - by MTS

  I recently upgraded to Quantal, and also switched up to emacs24 from 23. Everything is great, except for one thing: the icon in the Application Switcher for emacs24 is a horrible, low-resolution eyesore. Compare the two side-by-side: I've seen a couple of questions addressing issues like this, but they're not quite the same. This one says that it is happening with all icons, but that's clearly not the case here. And this one seems more relevant, but it is talking about Gnome, not Unity. In the comments to the one answer for the second question, it says to look at the icons in /usr/share/icons to see if they are low-resolution, and if so to replace them with better ones. There's a ton of emacs icons, in fact. They are in various subfolders of /usr/share/icons/hicolor and they are in sizes ranging from 16x16 to 128x128, and also there are scaleable .svg versions of the icons too. I noticed that there are no 192x192 or 256x256 versions. But it seems like that shouldn't matter, since emacs23 also didn't have icons in those sizes. Any help would be much appreciated!

• How to reduce the size of a pdf file?

  - by Nicole

  I'm looking for a way in Ubuntu to reduce the size of a pdf (by reducing the quality of the images). I know that this can be done in Ghostscript by typing the following command in terminal: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf The problem is that I can't specify the quality with any accuracy. The parameter -dPDFSETTINGS=/screen is the one that decides the quality; but the alternatives are quite rigid (for example it is possible to do -dPDFSETTINGS=/ebook for slightly better quality). I'm looking for a way to reduce the size of a pdf in a way that allows me to specify the desired quality numerically. I know that this is possible in a Mac, so it must be possible in Linux -- right? Any help would be well appreciated.

• Allow any arguments for a given command with sudo

  - by Mark L

  I have the following sudo config entry which I added via sudo visudo: mark ALL = NOPASSWD: /usr/bin/lxc-ls* I can run lxc-ls with my user fine but I can't append any parameters without it demanding I prefix the command with sudo. $ whoami mark $ lxc-ls test-container $ lxc-ls --fancy lxc-ls: error: You must be root to access advanced container properties. Try running: sudo /usr/bin/lxc-ls Any idea how I can edit via sudo visudo to allow for any argument after the command? I don't want to prefix the command with sudo as I'm using a python library to execute the command and it's being funny about sudo prefixes.

• How much time to wait to upgrade to a non LTS release?

  - by Jhonnytunes

  For LTS upgrades the recomendation is wait 3 months or first point release to is where the major bugs are fixed and the release is "stable" for production. What is the recommended amount of time to wait before upgrade to a non LTS release? Im just talking about the desktop version of course. Im asking because found this where say all release from 14.04 will be based on debian unstable: Cutting Edge: Starting with the 14.04 LTS development cycle, automatic full package import is performed from Debian unstable1 This is due to deploying ProposedMigration in the Ubuntu archive. From here.

• Any command line calculator for Ubuntu?

  - by AgentCool

  I am looking for a Calculator which can do calculations in the terminal itself without any other extra prefixes and suffixes. For example: If I typed something like 10000-9000 in the terminal, the answer should come out as 1000. Once again I am saying, I just need a quick calculator in terminal, without any characters added. I know if I switch to Python, it can do that but I don't want it in such a way.

• "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this?

  - by fahadayaz

  I have recently purchased a Novatech nFinity N1410 laptop and am having problems with the wireless, which sudo lshw -C network tells me is Centrino Wireless-N 2230 and using the iwlwifi driver. The problem is that after the device has been suspended, I am not able to get the wireless working again without a restart. The network indicator states that the wireless disabled by hardware switch. Though Fn+F2 is meant to be the wireless switch, xev tells me that the system doesn't see it as anything at all when I press this hardware combination. Also, though the brightness up/down buttons work fine, the volume up/down buttons do not work either. What can I do to fix this? I am running Ubuntu 12.10 with all available updates installed.

• How are typical users expected to read the documentation in /usr/share/doc?

  - by ændrük

  I only recently learned that there is a huge pile of documentation in /usr/share/doc. How on earth is a typical user supposed to find out about that? It seems like much of it is gzipped, and inaccessible with administrative privileges: $ gunzip examples/letter.tex.gz gzip: examples/letter.tex: Permission denied Are users expected to duplicate each item in their home directory just to read it, or is there a less tedious solution? This arrangement hardly seems conducive to regular browsing. How do normal people read this documentation?

• Evolution and thunderbird sharing same mail data?

  - by balki

  Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

• "Backup Intervals" in rsnapshot.conf?

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• Uninstalling ATI's drivers and installing NVIDIA's?

  - by whydidithavetobreak

  I replaced my card but I'm not sure how to set things up on Ubuntu. When the computer boots, it doesn't start GDM (I think that's what it's called). Instead, it asks me to log in the command line. If I try to do a startx, it tells me there is no AMD device connected or something to that extent. I originally installed the ATI drivers using the GUI. It said that I was using the limited drivers or something to that extent with a popup on the right of one of the taskbars, so I clicked there and updated it. I think it could also be reached by going to system administration restricted drivers or something close to that. I tried installing the nivida drivers by doing a "sudo apt-get install nvidia-glx-185" and then doing "sudo modprobe nvidia" and "sudo nvidia-xconfig" as this guy says but that didn't work. Modprobe couldn't find anything related to Nvidia and nvidia-xconfig wasn't an available command for me. Since I wasn't sure how to remove the ATI drivers I did that without messing with them. Not sure if that was a good idea.

• Share between Ubuntu machines

  - by Anero

  I'm sure it might be a very easy way to do this, but I haven't found how... I have two machines with Ubuntu 10.10 on the same network (just workgroup, no domain involved). On one of them I have shared a folder through Nautilus Folder Sharing. When opening the Network place on the second machine, I cannot see the first one listed, just Windows Network and when going into this folder I can see the Workgroup though when trying to go into it I get an Unable to mount. Failed to retrieve share list from server error. Is it required to do something else when sharing the folder through Nautilus?

• Gnome 3 panel and menus are all gone?

  - by Hannes

  I am running Ubuntu 11.10 using gnome 3 shell. I have set my pc to automatically log into gnome shell so I do not see the login screen. Today I installed some updates and now the gnome panel is gone. When my pc logs in I ONLY see the background. There are no menus, nothing! Even the exit, minimize and maximise buttons in the top tight corner of the windows are gone. Also, alt+f2 also does not work. Any ideas how to fix this? I have a Nvidia Geforce 7900GTO with the Nvidia proprietary drivers installed. I have also used the recovery mode and removed some packages that apparently were broken. Still does not work.

• My internet connection slows or dies unexpectedly

  - by genesis

  I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them. On Windows, everything's working fine and I had no problems with this. My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes. My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure. Is there a fix for this? iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Fsite1" Mode:Managed Frequency:2.442 GHz Access Point: C8:3A:35:40:43:68 Bit Rate=0 kb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=43/70 Signal level=-67 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

• AMD 6870 Twin Frozr II video adapter issues

  - by user35427

  Hardware: AMD 6870 Twin Frozr II (1GB), ASUS 990 chipset Software: Ubuntu 11.10 Built a new PC from scratch, loaded it with Ubuntu 11.10. It's displaying, but with poor resolution, unable to change, as it says no drivers are installed. Ubuntu indicates that there are 2 proprietary drivers available to download: ATI/AMD proprietary FGLRX Graphics driver (Post-release update) ATI/AMD proprietary FGLRX Graphics driver The first won't even finish downloading. The second downloads and installs, but when I restart the PC as requested it boots up, I see purple in the background, then the video feed just stops with a black screen. I can still hear ubuntu boot up though. It seems like I just need the latest drivers, googled around and not had much luck. I'm pretty new with Ubuntu, but have basic knowledge. Any potentially helpful information would be welcome.

• Ubuntu installer thinks my drive is empty, does not see windows paritions.

  - by John

  Hello, I am trying to install Ubuntu10.10 64bit. I just installed Windows 7 64bit moments ago. My drive is currently partitioned like so: 100MB Boot partition (automatically made by windows 7 installer) 390GB Windows partition ~1.6TB free space When I go through the Ubuntu installer it does not give me the option to install alongside another operating system. My only options are to use the entire disk or to specify partitions manually. When I chose to specify partitions manually it tells me that the drive is all free space! Windows is still booting and behaving normally, and I had not doing anything in Windows yet (had simply installed, booted for first time, then immediately restarted). I am even able to mount the windows partition within Ubuntu Live CD, and see it in the disk viewer (not gparted). Gparted in Ubuntu Live CD again reports no partitions, all free space. Not sure what to do :S. I have installed Windows7 alongside Ubuntu countless times, even Ubuntu 10.10. Thank you very much for your help :).

• See configured rules even when inactive

  - by Bryan

  Hello, I'm wondering if it's possible to get UFW to list the configured firewall rules even when it's not enabled. I only have ssh access to the server at this time, and I don't want to enable UFW if there's not a rule configured allowing ssh. However, since UFW is currently not enabled, I just get an "inactive" message when I run "ufw status". Is there a special flag I can use or even some config file I can look at to see what rules are configured even when the firewall is disabled?

It captures one screen but doesn't show the rest. I can capture my screen running if I use my flip camcorder but recordmydesktop will not work. Is there a way to capture live video playing on the desktop without using an outside camera? Brian

• How do I access the system tray?

  - by Jon

  So I'm messing around with Natty a little, and I noticed that all the apps that would normally use the system tray (or "notification area"?) aren't displaying there. Is that a bug, or is that the way it's going to be? I heard something about Ubuntu getting rid of that feature entirely. Is there a way to add it back? I mean, I didn't really like it, either, especially when there were apps that used it unnecessarily, but I can't use CryptKeeper at all now, or easycrypt, and I don't know whether Dropbox has synced without opening Nautilus.

  I'm using Ubuntu 11.04 and I'm having trouble connecting to internet via wifi. Ethernet cable works though. So when I log on it auto logs on to my wifi connection at home but after about a minute or so it gives me a popup: network disabled something about .local domain and something about Avahi network (sorry if you need more on what the popup says I will reboot and look at it again). I am using Atheros wireless card. My laptop is Asus G73SW and on the forum at notebookreview.com G73SW Owner's Lounge people said they had no problem with connecting via wifi from install. Please help me because I would love to keep using this beautiful OS.

• How can I use two video cards to power three screens?

  - by notatoad

  I have two Radeon 6450 graphics cards in my computer, with three screens. Only the screens plugged into the first graphics card are recognized and configurable in the displays setting panel. How can I use the displays plugged into my second graphics card? Both cards are present in lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc NI Caicos [AMD RADEON HD 6450] 01:00.1 Audio device: ATI Technologies Inc NI Caicos HDMI Audio [AMD RADEON HD 6450] 02:00.0 VGA compatible controller: ATI Technologies Inc NI Caicos [AMD RADEON HD 6450] 02:00.1 Audio device: ATI Technologies Inc NI Caicos HDMI Audio [AMD RADEON HD 6450] I'm using the open source driver instead of the proprietary driver because the proprietary driver won't output 1440x2560.

• FFMPEG not extracting part of the video

  - by DNA

  I used FFMPEG to extract portion (5 seconds) of a video like this: ffmpeg -ss 00:30:00 -t 00:00:05 -i original.avi cut1.avi and also like this: ffmpeg -ss 1800 -t 5 -i original.avi cut1.avi But what FFMPEG did was create a file starting at 00:30:00 and included the rest of the file instead of just 5 seconds. So instead of having a 5 second video clip, I now have the whole file except the first 30 minutes. What went wrong? I tried this with mencoder as well -- same result. EDIT 1 Strangely, this worked on OS X....
