• Canon MP280 All in One prints but scanner not recognized

  - by Chris

  I recently installed Ubuntu 12.04 LTS after not using any Linux distro for several years. My Canon MP280 worked perfectly as far as printing goes and I was even able to set it up on a Samba share and print from a Windows 7 machine. However when I open Simple Scan it does not detect a scanner. I did find some instructions online but the scanner is still not recognized in Simple Scan even after installing a couple .deb packages from the Canon site. I also couldn't seem to find the ScanGear package after installing those .deb packages as well but I haven't had a chance to delve fully into it. Thanks for your time!

• New Dash features and Online accounts missing after 12.04 to 12.10 upgrade

  - by motobói

  I performed upgrade to 12.10 from 12.04 using update-manager. Unfortunately, there was some error, because when I came back from the coffee, the screen was black. I opened a terminal (Ctrl+Alt+T) and killall dpkg, which seemed to be waiting for user input for configuration file update (xdg package , if I remember well). After that, I did a do-release-upgrade, which seemed to work well, because I ended on a graphic session after reboot. The problem is that some 12.10 features are missing, as Online Accounts and Dash new online results. This made me suspicious of missing packages or something like that. Please take a look at upgrade logs and my new dpkg --get-selections output: https://gist.github.com/3919006 dpkg --reconfigure -a didn't solved the problem nor apt-get -f install showed any problem. do-release-upgrade say my system need no news packages (even if I change /etc/lsb-release to 12.04) If someone give me a dpkg --get-selections of a vanilla 12.10 installation, may be I can force system reconfiguration.

• Never before had a problem with Ubuntu desktop graphical display; Trying to use nvidia GT630

  - by focaccio

  I've been using ubuntu since 9.04 and never had a problem with Ubuntu brining up the desktop graphical user interface. However I am currently not able to see anything graphical past the install screens. I have an Intel DP55KG motherboard and just installed an nvidia gt630 graphics card (zotac), since the old graphics card failed. I can install the server and see text. So I do a apt-get install ubuntu-desktop...or apt-get install kubuntu-desktop...or apt-get install xubuntu desktop, but after the reboot there is no display...its like something is hung up. I tried using the Live quantal dvd and I do see the graphical prompt to try without installing, but after that the screen goes blank. I've tried two monitors and the same thing happens. There is a faint "glow" on the screen and I do not get a "no input signal" from the monitor, so something is happening. I can install an old OEM of XP so I know the video card and motherboard are at least semi functional. Any help is appreciated. Thanks, Greg

• Option Button in Keyboard Layout > Input Sources is not pressable

  - by user98647

  I would like to set the Caps-lock key as a Compose key, which you do, as far as I remember, by pressing the Options Button in Keyboard Layout Input Sources and then enabling the appropriate option there. That Button is not pressable though since I switched to 12.10. It did work in previous releases of Ubuntu. gnome-control-center puts out these errors, when I click on Keyboard Layout: (gnome-control-center:3645): common-cc-panel-WARNING **: Could not find current language '?\u0003C!\u007f' in the treeview (gnome-control-center:3645): common-cc-panel-WARNING **: locale '"en_US.UTF-8"' isn't valid I'm not sure if the errors are related though, maybe they are related to the "interface switching to chinese bug" which seems surprisingly widespread: Language changed to Chinese, how do I change it back? Language Support has an unwanted Chinese language option Nautilus Folders Turned Chinese Desktop 12.04 gnome/cairo suddenly in Chinese Unwanted Chinese language got set in system settings I cannot set my system back to English from Chinese Language Gnome-classic language turned into Chinese, how do I change it back to English? Strange display language in gnome shell I'm not sure they are related to this bug, but I just wanted to mention it, maybe it helps!

• Python (v2.7) requires to install plugins to create media files of the following type: Vorbis encoder

  - by LibraryGeekAdam

  This is the message I get when I try to rip a cd from any player. I usually use the stock Rhythmbox but have tried others to no avail. I have just updated to 12.10 from 12.04 and I had no problems in 12.04. I have read the other posts and have switched to the Main Server in the Software Sources menu. I have installed Ubuntu Restricted Extras. Nothing seems to help. I would appreciate any help. "Python (v2.7) requires to install plugins to create media files of the following type: Vorbis encoder" Thanks!

• How to make my own web app

  - by pgrytdal

  After switchign to Ubuntu 12.10, I have discovered I like the Web App's feature. I do not, however, like the Gwibber application, or Twitter.com (and it's web app) because of lack of features. I do, however, like the Twitter client Hotot, but for some reason, is not working for me right now. I was wondering if there was a way I could make web.tweetdeck.com a Web App, until I can get Hotot working for me? Thank you!

• default mount point changed for external HD

  - by JhmL

  The default mount point for my external HD changed when upgrading from 13.04 to 13.10. Now the username is added as an extra level before the hd label. So it used to be /media/nameofhd and now it became /media/username/nameofhd This breaks a lot of links I have set up to this disk. I know that I can mount it manually and even automatically through /etc/fstab. What I want to know is why this behaviour changed and how I can change it back to the original? blkid and fdisk don't show anything suspicious. thx!

• tty1 prompt before lightdm

  - by David Weldon

  After upgrading to 13.10, every time I boot I'm shown a login prompt (tty1) for ~30 seconds before lightdm automatically starts. Everything works fine after that. Any ideas on what I could try to fix/debug this? My /var/log/lightdm/x-0-greeter.log contains lines like the following: ** (at-spi2-registryd:1381): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files ** (at-spi2-registryd:1381): WARNING **: Unable to register client with session manager WARNING: Failed to open sessions directory: Error opening directory '/usr/share/lightdm/sessions': No such file or directory ** Message: PID 1534 (we are 1534) sent signal 15, shutting down... ** (gnome-settings-daemon:1401): WARNING **: Name taken or bus went away - shutting down Searching for these errors results in a variety of bugs filed over the years. Maybe a clean install will fix this.

• How to protect Ubuntu from fork bomb

  - by dblang

  I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one never knows what can happen. I heard that some OS allows the administrator to place some limit on user processes to mitigate the effects of fork bombs, is this protection in Ubuntu by default or would a person with sudo privilege have to set this? If so, how?

• Intermittent sound on an Medion Akoya S5610

  - by ej159

  The sound on my machine (Medion Akoya S5610) works intermittently. If I reboot enough times I do get sound. This happened before I upgraded, when running Oneiric too. I have fiddled around with alsa-base.conf, putting in different values for model in options snd-hda-intel model=but still the issue persists (although I get the impression that I am more like to have sound on the next reboot if I have edited that file although I can't be sure of this). Adding index=0 does not help the situation either. I have been thinking that this problem could be related some how to the order that driver modules are loaded. The snd-hda-intel module is also used for the sound card (ALC888) in my graphics card. Could it be that these are some how competing? If so, how do I add a preference when they are using the same module? This is the result of lspci -nn | grep Audio (when sound was not working): 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 01:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI RV620 HDMI Audio [Radeon HD 3400 Series] [1002:aa28] I've been wrestling with this problem for ages and ages and have spent days looking for answers on forums but to no avail so I would appreciate any help you can give. Many thanks

• Unable to boot 12.04 server: no LVM activated and impossible to mount /

  - by baronKarza

  I'm stuck in the Busy Box shell after upgrading from Ubuntu server 11.10 to Ubuntu server 12.04 64 bit. During the booting phase the system hangs while mounting root filesystem. My system is so configured: /dev/sda1 -- /boot /dev/mapper/vg-lv_root /dev/mapper/vg-lv_var /dev/mapper/vg-lv_tmp When the boot process fails and I'm forwarded to the busybox shell, if I type vgchange -ay I can mount my volumes and all it's OK. But it does not enable LVM automatically so that it is impossible to mount root, var, and tmp. I tried to start with a Knoppix, chroot, reinstall (aptitude) both kernel and lvm2 as suggested by this tread "Fixing unbootable installation on LVM root from Desktop LiveCD": nothing changed. I can't figure out what is the problem. Any suggestion is welcome. Thanks in advance.

• How do I include a password with SSH command? (want to make shell script)

  - by Evan

  I'm trying to SSH to a server on startup with a .sh script, but that will require me to enter the password for the account on the server that I'm SSHing to. I did some RTFMing, and I see in "-o" that it has "PasswordAuthentication" but I'm not sure how or if I could use that option. As this will be in a shell script, obviously I'd like to have the password in that file, or in any case not have to enter in the password manually every time the script runs.

• 12.10 Wireless networking

  - by user108594

  I downloaded ubuntu 12.10 using WUBI and cannot connect to the internet. I removed it and downloaded ubuntu 12.04 still cannot connect. This I assume rules out the program being the problem. I reinstalled 12.10. When loaded I get the same message W/red (x) stating Internet not connected. I went to the Settings drop down box and it does not reveal the network list but (enable networking has a ck mark). Am running a HP Laptop with a w/7/64 OS that has a kill switch that indicates (orangeno connection) I downloaded 12.10 on my desktop (on the same network) and everything OK.

• How can I personalize my MacBook Pro Touchpad?

  - by Barkerto

  I'm running Ubuntu 12.04 LTS on a MacBook Pro 5.5. I'm just wondering if there is something that takes all the kinks out of the touch-pad. It works good, but it feels sluggish, double tap works about 75% of the time and sometimes while I it somehow selects something on a different page (although I'm not sure if that has to deal with the touch-pad and not weird laptop bugs for a new LTS) If there are any programs, apps, commands aside from the built in system preferences mouse and track-pad touch-pad menu that allow someone to "optimize" touch-pad potential.

• Acer Aspire One 725 - missing graphic card driver for Radeon HD 6290?

  - by Melon

  Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with (or something similar) AMD Radeon HD 6290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: I have tried installing fglrx but I get the following error (either I don't have libraries or someone didn't make a clean build before release ;) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘KCL_MEM_AllocLinearAddrInterval’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:5: error: implicit declaration of function ‘do_mmap’ [-Werror=implicit-function-declaration] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘kasInitExecutionLevels’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: error: ‘cpu_possible_map’ undeclared (first use in this function) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: note: each undeclared identifier is reported only once for each function it appears in /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: warning: left-hand operand of comma expression has no effect [-Wunused-value] Update 2: After fixing the erros in compilation, ubuntu acts bizarre and unstable (no left icon panel, no upper panel, cannot run any programs, I only see desktop)

• I have Ubuntu 11.10 and for no apparent reason my sidebar suddenly will not hide, how can I reverse this?

  - by cathy

  I have Ubuntu 11.10 and for no apparent reason my sidebar suddenly will not hide, I did not go into system settings or anything like that. I googled this, but everything I found had me downloading something to be able to fix it. However, as it changed without me downloading anything, I'm hoping it's possible to change it back without downloading anything. I read somewhere that I should go into "System setting", "appearance", "behaviour" and change it to "auto-hide", but I did not have a "behaviour" tab in "appearance". I would normally be able to just deal with it, but it is preventing me from being able to click the "back" button when I am in a browser. Does anyone

• How to remove session entries from LightDM?

  - by Lexalt

  I recently added Cairo Dock to my GNOME Shell in 11.10. Cairo Dock is GREAT, but I'm left with one little problem that I'd like to fix: after installing Cairo Dock, LightDM includes two extraneous entries to non-working desktops. (The entries to working desktops remain unaffected, so I guess I could just ignore the extraneous entries, but...) So I'd like to remove/edit the extraneous entries in LightDM. I've looked and looked for discussions on how to do so, but haven't had much luck. Any suggestions on how to go about editing the login menu in 11.10?

• I want to fix a bug. Where do I start?

  - by Ingo Gerth

  Although I am not a professional programmer, I have written a program or two. Yet, nowadays every engineer and scientist learns to program a bit as well, and as such I am used to writing programs in Python, C and MATLAB. Now I want to give back a bit to Ubuntu and its great folks and fix a bug! I had a look at the list of the bitesize campaign and had to find that most of them are not that easy for me to fix as I suspect they require a lot of time to get into the matter, and I do not have that. Still I discovered this one and it looks manageable and like a cool feature to me. As I have never written a patch or released a program to the wild before though, I have no idea where to start. What should be my first step to tackle that problem? Bottom line: Where and how do I start fixing that guy?

The Nexus 4 had the initial Touch dev preview on it, FYI. I saw no separate instructions for upgrading from that.
