• Remote Desktop between Ubuntu Machines

  - by user19192

  My desktop and my laptop are connected to the same router. I want to be able to remote login from my laptop to my desktop. Laptop is 12.04 and desktop is 12.10. I tried putting xrdp on my desktop, but remmina wouldn't work with it. I also tried the default screen-sharing, but it was very slow. Also tried rdesktop but it was very slow. I am on 12.10, FreeNX looks like a good option but they don't have a 12.10 release. And when I tried to install the 12.04 release, I got errors about dependencies missing. How can I get local-feeling remote login speeds?

• Adobe AIR install problem, Ubuntu x64 14.04

  - by Den Rimus

  Haven't seen this kind of error on askubuntu yet. Did everything as it says here: How can I install Adobe AIR? After sudo ./AdobeAIRInstaller.bin shows this image: dropbox.com/s/wg6cv03h5n1tqgr/adobe_air.png Meanwhile terminal shows a bunch of such messages: (setup:2579): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine", Nothing is installed. Those murrine - it showed another code before ( another than setup:2579) - I googled it, installed something, it showed another code - I googled it, installed something, etc. Doesn't seem to affect installation anyhow.

• Workspace Issues on ubuntu 12.10

  - by JaySch

  I'm having the following problem with 12.10 Unity running on a Toshiba A505 16" display laptop using an external 24" Samsung LED monitor (resolution 1920 x 1080 (16:9). Also using the default 2 x 2 workspaces: After powering up the laptop, I Click the Workspace Switcher and the 4 images which represent Workspace 1, Workspace 2, Workspace 3, and Workspace 4 are visible but are in a very elongated, stretched out aspect ratio. Also, any desktop icons placed on the left side of the screen don't show up when I go to full view on any of the 4 workspaces. To resolve this issue, I open up the laptop lid until the video display switches from the external Samsung LED monitor to the internal laptop display, which renders the four workspaces perfectly. I then close the laptop lid and now the workspaces display the correct aspect view; both in the workspace switcher thumbnail view an in full view. I can now see the full desktop, including any desktop icons. Is there a way to configure my system so that Workspaces work properly when the laptop is connected to an external monitor without having to open and close my laptop? Thank you.

• Problem with Ubuntu 12.04 boot

  - by Etienne

  I'm having a problem as stated in the title regarding bootup. What happens basically is that after grub is loaded the system doesn't boot. I get a black screen with cursor blinking then the screen darkens ( switches off ) and keyboard is unresponsive. Today I have re-installed everything on a new hard drive and it happened again. This has been observed when running kernel 3.5.0-30 and 3.5.0-28. System is an HP6550b. Can someone help me on this please ? Many Thanks!

• Ubuntu 12.04 + Bluetooth problems with maintaining connection

  - by ifndefx

  I have an Apple Wireless Mouse, Apple Wireless Keyboard, Apple Wireless Trackpad, and a pair of headphones. All of these connect to the computer via a Bluetooth dongle. After several hours I've managed to get the devices paired (all except the headphones) with the computer. However, I'm facing a problem where a connection can't be maintained even with one device. I first started with the gnome bluetooth applet, this couldn't even pick up devices, so I installed blueman, and this at least detected the devices but it couldn't keep the connection going. Then i read somewhere to get hidd installed and use the command line using the mac address of the device (which I got from blueman) and this worked really well, the connection was stable, but there's still a couple of issues that I need help with: If I am to use hidd I need to execute this via terminal, which means for the keyboard and the mouse I need to have two of each. This doesn't make sense. I need the bluetooth daemon to have started with the devices picked up a lot earlier, and especially at grub bootloader. The mouse and the trackpad both work if i use hidd, however, I cannot get the right mouse to work nor the scroll wheel to work. The headphones don't work period, they don't work with any of the bluetooth applets, and with hidd either. When I use blueman aplet, it attempts to pair and states 'Authentication Rejected". The headphone is Phillips SHB9100. If someone can help me with this, I would be grateful.

• Cheese Not Working in Ubuntu 11.10

  - by user34305

  When i launch Cheese, nothing launches nor the green light on may laptop webcam glows. I typed cheese in terminal and i got cheese:2293): Gdk-WARNING **: The program 'cheese' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 144 error_code 1 request_code 136 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

• Ubuntu worldtime desktop clock widget?

  - by ubuntico

  I am aware that in Unity we can add world time by clicking on time bar. However, it's still a list of locations and sometimes it may be hard to quickly find the timezone of interest. Is there any tool which can put a multiple clock instances on the desktop representing each timezone of interest? Similar to the clock in Windows 7. To be more clear, I am not looking for a weather widget, but a simple clock widget so that I can track time in different timezones.

• Graphics problems: noise-like glitch, and screen freezes in Ubuntu 13.04

  - by user207253

  I have recently upgraded to 13.04 and am using unity. I am experiencing two intermittent problems with the graphics: 1) All or part of the screen is taken up by 'noise', which lasts for about a second, see screenshot: 2) The launcher panel freezes. I can still move the mouse and the keyboard responds to function keys (I can dim the screen), but I cannot select anything. At the moment I recover by ctr-alt-f1, and restarting lightdm. My computer is a Samsung Chronos 7 laptop, model NP700Z5C, with Intel HD 4000 graphics The same problems occur with lightdm and gdm. I have attempted to install the intel drivers (as the screenshot hints) but these are not indicated as additional drivers in software & updates so I'm not sure whether they are in use. Any suggestions?

• WIfi Problems Ubuntu 13.10

  - by user289429

  i've been searching the forums for two days now but none of the answers seems to work for me. I have an acer extensa 5630 which has an Intel WIfi 5100. But even when i am right next to my router i cannot detect the wireless network. The weird thing is, that when i create a hotspot from my mobile phone it automatically detects it and connects to it.I think i do have the correct drivers installed. Thanks

• Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

  - by Villi Magg

  I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.

• HP 655 notebook (ubuntu 12.04) keeps consuming energy after closing the lid

  - by Bastian van Binsbergen

  I am unable to change power settings so that when I close the lid the battery stops consuming energy. There are three options in the power settings menu: When the screen is closed: 1 Do nothing 2 Pause 3 Sleep First I could not change anything. I see all the options but I could not click on option 2 and 3. (grey text instead of black) I already made it possible to put in to sleep mode. But I can't pause (suspend) the laptop. Anyone an idea?

• ACPI=OFF in Ubuntu 11.10

  - by Mark

  When I tried to upgrade from 11.04 to 11.10 the system froze, so I've been playing around with a couple other linux builds (Fedora, Mint, and Puppy) the last couple days and I keep coming around to the same problem: a lockup during boot; each build referencing a kernel error. On another board someone suggested booting with a boot up line of "ACPI = off". It works with other OS', but I'm not sure where to put this command. Can anyone 'enlighten' me, please?

• DVD wont mount Ubuntu 12.04

  - by CyborgGold

  I can't seem to be able to mount my optical drive. I have tried numerous solutions from this site with no results. I am not able to see the device inside the file browser either. There is a DVD in the drive. I am running 12.04 on an HP g60-235dx portable. I have a link below to the specs. I will also list what I have tried (that I can find back right now.) I know the drive is functioning, because just before Windows 7 crashed and my MBR went fubar I was watching movies just fine. I am fairly new to linux, so don't assume I know anything. Ok, so here is what I have tried: sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list sudo apt-get --quiet update sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring sudo apt-get --quiet update sudo apt-get install libdvdcss2 dmesg | grep sr0 (no output) apt-get install libdvdnav4 (already installed, and up to date) sudo /usr/share/doc/libdvdread4/install-css.sh ls -l /dev/cdrom /dev/cdrw /dev/dvd /dev/dvdrw /dev/scd0 /dev/sr0 ls: cannot access /dev/scd0: No such file or directory lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrom -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrw -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvd -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvdrw -> sr0 brw-rw----+ 1 root cdrom 11, 0 Sep 10 03:51 /dev/sr0 wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'TSSTcorp' 'CDDVDW TS-L633M' ------------------------------------------------------------------------- sudo lshw optical *-cdrom description: DVD-RAM writer product: CDDVDW TS-L633M vendor: TSSTcorp physical id: 1 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0200 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc sudo lshw | grep cdrom *-cdrom logical name: /dev/cdrom Spec sheet for portable: http://www.cnet.com/laptops/hp-g60-235dx/4507-3121_7-33496192.html If you need any more information than all of that... please let me know.

• Compiz using 40% CPU on Ubuntu 13.10

  - by Olli

  After upgrading to 13.10, compiz process has started taking up to 40% of CPU resources. In addition, Unity is sluggish just like in this recent question Compiz at 30% of CPU on Thinkpad T420. My PC is HP Compaq NX6310 and Compiz version is 0.9.10.2. First I had error message during boot, but did find solution for that (Bug #1014289) by updating the kernel to newer 3.11.4, it did not change the CPU usage. For the CPU problem I tried solution for Bug #1221837 by adding the line MESA_GL_VERSION_OVERRIDE=1.4 in the file /etc/environment - that did not help me, so my problem seems not to be the same bug. Any suggestions on how to resolve this issue?

• No sound Ubuntu 12.04 through HDMI

  - by MikeMan

  Specs: Asus G73JH i7/720; ATI Mobility 5870 I have read through a lot of threads on getting HDMI sound to work and non of them have fixed my issue. Granted I am very new to Linux and know only the GUI aspect of what it does from finding similarities that Windows 7 has. I would like to become a Linux Power User and I figured this would be a good step to get started. I was able to successfully install my graphics driver and it shows in use. I connect the HDMI to my HD TV and I get no sound. I don't care about auto switch for sound, that would be great but not necessary. I just want my sound to work through the HDMI. What I have tried: Changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" pact set-card-profile 0 output:hdmi-surround Failure: no such entity Sound Settings: Right-click Sound indicator ? Sound Settings ? Output Tab, and set Digital Output (S/PDIF) Built in Audio Speakers Built in Audio I only get 2 settings. If I right-click the area below those 2 in the "play sound through" box, I get no "show hidden devices". I am also doing all this with the HDMI connected to eliminate any possibility for error.

• Sending Emails from existing SMTP host from Ubuntu Server

  - by ezgoodnight

  I feel like my problem is very simple, but I've been trying for quite some time and haven't cracked it. You experienced server guys will probably laugh at this, but I'm finally at the point I need help or I'll never get anywhere. I have a little box running 12.04 LTS and I've wanted to script some status checks and have the server send me an email and schedule this with cron. I basically want a command line mail client that I can set up as easily as Thunderbird to send through my existing SMTP through the command line. Something that can easily be rolled into my bash scripts. I already have a remote host handling our email, SMTP, MTA, all that garbage. I don't particularly want to set up a relay just to send email when I have one that everyone else in the company already uses. I've tried, but there are too many aspects I don't understand AND I don't see why I should set up something local when we already pay for a remote host to do these things. If I absolutely have to set up sendmail or postfix, then so be it, but I'd appreciate a simple alternative. I'm open to practically anything at this point.

• Ubuntu crash problem, need fix

  - by Brad

  Upgraded to 12.04 LTS Beta 2, on a Dimension E310. The unity Sidebar crashes while I use Software Center. The only way I can close Software center Is to either power off my computer or use force quit app on the unity side bar. Thats why I believe it's the sidebar crashing instead of the software center. But the other problem is, apport don't recognize the bug so nothing is sent. How do I file this bug? I looked in VAR/Crash and there was no crash report.

• Unable to start Ubuntu 12.04. The system is running in low-graphics

  - by kaleidoscpicsoul

  I am a newbie to Ubuntu. I installed Ubuntu 12.04 using a USB Stick and it was running all fine for a few weeks and this error popped up. According to one of my friend, the best way was to re-install Ubuntu. Being from a non unix background i thought the same too and after the second install it happened again, but only this time was much quicker, in 3 days. I don't want to re-install Ubuntu every time this happens. I am a complete newbie to Linux which means that i am really bad at using terminal. I know there are other people who fixed this issue using this very same forum, but unfortunately the answers provided are too complex for me to understand. Please let me know how to do this. Things I want to let you know: I would need help step by step if that is alright with you. After i get the error i get the options and i click exit to console login I get the following message in a black screen (which i think is a command line sort of thing): * Stopping save kernel messages [OK] apache2: Could not reliably determine the server's fully qualified domain name,using 127.0.1.1 for ServerName [OK] * Starting web server apache2 and a blinking cursor. So basically it looks like a dead end for my non unixy eye. And one final thing is before this issue had happened i had tried configuring Python to Apache2. For that i had uninstalled and installed LAMP server several time and edited the configuration files too. I don't know if this really is a concern, but I don't know.. I have a USB with Ubuntu 12.04 in it so i can install it anytime. (But i want to know what the issue is rather than running away) . I migrated to Ubuntu from Windows and i have no plans to go back. I think that's from my side. Please let me know if there are any questions.
