• ubuntu 12.04 ambiance dark side bar issue when clicking folder on desktop

  - by Lou Crittenden

  ubuntu 12.04 gnome: concerning an updated custom ambiance theme: why is there no dark side bar when I click on a folder, like the home folder icon on the desktop, but the theme works as planned when I type "nautilus" in the terminal to open the home folder or when opening a folder up as root? Permissions issue perhaps? note: i am using cinnamon instead of unity and i noticed it uses the nemo file manager instead of nautilus and i suspected that it was causing me the grief. so i uninstalled it and now am using nautilus only as the file manager. i found this out when i typed: "sudo killall nemo" and the problem went away. i'll see how this goes... (and hopefully cinnamon doesn't care about it...) has anyone else had any issues with this?

• Trouble after Ubuntu 12.10 upgrade

  - by highsciguy

  Over night I tried to upgrade to (k)ubuntu 12.10. Unfortunately kdm (neither lightdm) doesn't show up after boot. I found several posts describing errors due to the migration from kdm to lightdm. Some sugest reinstallation of kdm. Therefore I logged into a shell and tried to install it using apt-get. However it turned out that network is not available. ifconfig showes that only the loopback device lo is available. What can I do to get lan or wlan network working on the commandline? I relized that grub still runs the old tuxonice kernel which I installed from ppa. Is it possible that the installation didn't finish and left me in an inkonsistent state in which the kernel version does not match the modules? How can I proceed the installation from the downloaded packages?

• LIRC-ZILOG on ubuntu 12.04

  - by aoman

  I followed these guides to configure a Hauppauge PVR, and after compiling the hpvr modules, I have this problem: (that also includes the zilog one) # locate zilog /lib/modules/3.2.0-29-generic/kernel/drivers/staging/media/lirc/lirc_zilog.ko /lib/modules/3.2.0-34-generic/kernel/drivers/staging/media/lirc/lirc_zilog.ko /usr/src/linux-headers-3.2.0-29-generic/include/config/lirc/zilog.h sudo modprobe lirc_zilog FATAL: Error inserting lirc_zilog (/lib/modules/3.2.0-34-generic/kernel/drivers/staging/media/lirc/lirc_zilog.ko): Invalid argument The PVR works and I can get a test video with sound. The remote does not. I want the transmitter to work so it can automatically change the channel on the cable box and find the video I wanted to record. The LIRC sources are not on Ubuntu sources and so I can only guess at what commands I might have to use. How do I resolve the error and get the remote working?

• Problem with graphic Ubuntu 12.04 (not sure if it's because of the graphic driver)

  - by Duy Nguyen

  Ubuntu 12.04 was functioning properly . Then after an update, some graphic elements stop working properly. I could not launch programs that has 3D elements. Work space switcher's window displays 2D window instead of a 3D like usual. In Details menu, the Graphic row is blank. I am using Intel GMA 4500MHD graphic card. I am guessing that the driver is not properly installed? Anyone has the same issue? Please help!

• How to prevent Ubuntu from changing screen brightness?

  - by cholazer

  I have recently installed 12.04 on ASUS-K53SV-V300. I can change the brightness on start-up with: echo 0 > /sys/class/backlight/acpi_video0/brightness >> /etc/rc.local or manually by Fn key. But, whenever Ubuntu dim my screen brightness to save power or wake-up from suspend or inactive for 20-30 seconds, brightness reset to high (my problem get much more when on battery). How can I disable screen brightness service to prevent it from changing my brightness? What service work on screen brightness? If I disable this service, can I manually set brightness by command? I found a program to work on brightness instead of default power manager.

• Unwanted authentication request window at login after upgrade to Ubuntu 13.10

  - by UBod

  I recently upgraded to Ubuntu 13.10 (64bit) on my Dell Laptop. Since then, at each login, a dialog window entitled "Authentication request ... Please enter the password for account "[email protected]"." appears (I would rather post a screenshot if I could, but I am not entitled to do that because I do not have the necessary 10 reputation credits). I neither have any idea why my password (I checked it a hundred times) does not work ("Password was incorrect") nor why this dialog is displayed at all. As said, I never saw it before 13.10. I looked around in different forums and it seems (please correct me if I am wrong) that it stems from evolution server. I also deleted ~/.config/evolution/ entirely - without any effect. Further note that I am not using evolution at all and I would rather like to get rid of it completely, but I do not dare to remove evolution-server. Any ideas? Thanks in advance, Ulrich

• Multiple Monitors using nvidia-prime or bumblebee on Ubuntu 13.10

  - by user205626

  I've been unable to get multiple monitors to work with Ubuntu 13.10 using nvidia-prime or bumblebee. Could someone point me in the right direction? With nvidia-prime, I've tried the xorg.conf here http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html, but I boot into "low graphics" mode and have to revert to get a desktop back. Any suggestions would be appreciated. Thanks. Edit: I've given up on nvidia-prime; I missed the fact that it never turns off the discrete card... So, I'm back to trying to get VIRTUAL displays working with Bumblebee.

  Like every single update on Ubuntu system, my graphical system is completely broken after updating to version 11.10 http://i.imgur.com/YIHfA.png As shown in the image, the date is in the middle of the panel, There are many icons missing (network connection icon, skype) There's no right click menu when I try to right click on the panel and many programs don't have their menus (file,edit,view... those things). How do I fix this? I have gnome-panel, I don't want Unity and I'd rather install windows 95 before I switch to it.

• Is there a better way to run ubuntu from usb disk

  - by Adam Butler

  I have an old laptop with a broken hard drive controller and am running the previous ubuntu from a usb. I installed this as per standard instructions by running some program that copied the live cd to the usb. This has had a few problems, it seems like it was just made for trying and not for everyday use. Ideally I would like to do a proper install to the usb disk instead of just running off the installer disk. Is there a way to do this? The main problems I have are: When adding mounts to fstab it gets overwritten on each reboot When installing updates the kernel cannot be updated

• Configure firewall (Shorewall/UFW) to allow traffic for services on an Ubuntu Server

  - by Niklas

  I have an Ubuntu Server 11.04 x64 which I want to secure. The server will be open to Internet and I want to be able to SSH/SFTP into the machine and the SSH-server runs on a custom set port. I also want a web server accessible from the Internet. These tasks seems not to hard to perform but I also want SAMBA-shares to be accessible from within the local network and this seems to be a bit trickier. If possible I also want to be able to "stealth" the ports necessary to protect the server further but also allow the SAMBA-shares to be automatically found within the local network. I've never configured firewalls before except for a router and I always bump into a bunch of problem when doing it all by myself so I was hoping for some tips or preferably a guide on how to this. Thank you! Update: On second thought I'd could just as likely go with UFW if the same settings are achievable ("stealth" ports).

• Ubuntu 12.10 automatic logout

  - by anthony

  I just had a new desktop constructed and installed ubuntu 12.10 which was successful for the most part but every time I open up some applications like thunderbird I get automatically logged out and all my windows are closed. System error messages also come up from time to time. Also I'm not sure if this helps but if I select the "Use system title bar and borders" in chromium I will also get logged out and from that point won't be able to use it without getting logged out in the future. If I click on particular links as well. If anyone has any tips on how I can isolate and fix the problem I would greatly appreciate it.

Please have a look at the log file for details: /var/log/jockey.log"

• 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?

• Ubuntu slow on HP 2000 notebook with Apu e1-1200

  - by user169861

  I am using HP 2000 notebook which initially came with Windows 7 64bit. It has 4gb ram, AMD APU E1-1200 (1.4ghz) with Radeon 7310. With Windows it worked ok, so I decided to switch to Ubuntu. I installed 13.04 64bit at first, but responsiveness wasn't that good (opening windows, menus, Firefox, dash search) even if it was way better during the testing from live USB. I tried different kind of drivers for graphic card, 13.6beta, 13.4, fgrlx proprietary, upgraded kernel but the situation was the same. Then I tried installing 32bit version but the results were identical. After that I tried LTS version 12.04 and Xubuntu 13.04.. Responsiveness wasn't that different at all. Not sure what to do, and I wouldn't want to go back to Windows. This machine is not a beast, but it should be enough to deal with Unity or Xfce without troubles. Oh yes, I have insydeH20 BIOS with not so many options at my disposal. Thanks and best regards,

  Back on 13.04 it didn't occurred.

• Ubuntu 12.4 cursor changes

  - by mantic0

  I have a weird problem with my Ubuntu 12.4 dual screen setup (Toshiba laptop + one monitor). After a while the cursor on one screen completely changes its shape (not every time). I don't really know how to describe it because it's always something else. Sometimes I get four or five vertical lines instead of a cursor, sometimes I can only see part of the cursor, etc, sometimes weird shade appears. This only happens on one screen simultaneously. If I go to the other screen, the cursor appears to be fine but when I change screens, the cursor changes. I tried to do a screenshot but when I do, the cursor looks just fine. I'm using Unity and Gnome 3 but the problem is on both desktop environments. Nothing is wrong with my screen though because I'm also using Windows and I don't have any problems there.

• how to recover deleted ntfs patition with data entirely while installing ubuntu 13.04

  - by Anson Varghese

  I've installed ubuntu 13.04 onto my hp 2231tx computer. During installation all of my data was erased. I didn't know all of my three partitions would be deleted. I was shocked after finding out that all of my personal data was erased. I didn't know what to do to resolve this problem so I search google for an answer. I found a program called testdisk and I used it to recover about half of my data. Among this data weren't my personal photos and videos. Is there a way to recover the other half?

• Ubuntu 12.10 "Turn screen off when inactive for: Never" still turns off

  - by Will

  After a fresh install of Ubuntu 12.10, my screen still goes off after about ten minutes. I've been to the Brightness and Lock control panel. The Turn screen off when inactive for: setting is set for Never. I've been through the dconf Editor searching for power, screen, and idle changing parameters. This doesn't seem to have any effect on the display timeout. Here's one more interesting thing, the screen doesn't go off, per se. It just goes black. Meaning, the back lighting is still on, and all the pixels are black. When it goes black, it does a very pleasant quick dim to black. Similarly, it quickly un-dim's after a key press, mouse movement, or mouse click. So, I'm feeling this is more of a software setting the timeout, not a power saving function.

• Boot Ubuntu from a bootable USB hangs on purple screen

  - by user210946

  I recently bought a laptop (Lenovo Y410P) with Windows 8 pre-installed and I'm trying to dual boot Windows 8 and Ubuntu 13.0. I created a bootable usb using Pendrive. Then I changed the Boot Mode to Legacy Support and the boot order so it boots from the flash storage first. When I restarted the computer, I got the error message "SYSLINUX 4.06 EDD 2012-10-23 Copyright (c) 1994-2012 H. Peter Anvin et al" and it just hung there. Fair enough. After some googling I formatted my flash drive in FAT format instead of FAT32. The "SYSLINUX..." error message is gone but now it hangs on a purple screen http://imgur.com/WbdXpZN Does anyone have a suggestion what to do here? I've looked at various posts but none of them seems to have a solution that the author confirmed it worked.

• Wifi won't work without ethernet (Ubuntu 12.04)

  - by alok

  I have a strange problem. I am running Ubuntu 12.04 on a Dell Studio 1558 laptop. I'm usually unable to access Wifi (I have a BCM43224 wireless card with the STA proprietary driver installed.) So I have to unplug the ethernet cable from my Wifi router and stick it into my laptop's ethernet port to access the Internet. But when I stick the cable back into the Wifi router and try connecting to Wifi, Wifi inexplicably starts working. How can I get Wifi to work all the time without having to 'jumpstart' it with an ethernet connection?
