  - by Jake Newkirk

  How do I change the color that the system displays just before the login screen is displayed? Here is the boot sequence on my machine in the order that things are displayed: The BIOS screen is flashed. A Black screen is displayed for a few seconds. My Plymouth splash screen is displayed. Purple screen is displayed for a few seconds (This is what I want to change). Finally, the login screen is displayed. Please let me know if you require any additional information while addressing this problem and as always, thank you for your time.

• AMD graphics drivers

  - by user284659

  I have a new laptop with dedicated graphics card and I decided I will go with Ubuntu 14.04. All is just fine and I love it but the repos for graphics drivers from Canonical are just well... old .Is there any problem if I install my graphics drivers from AMD's official website and not from Software Updater? It's just that from there i get the latest and greatest.I read the realease notes and 14.04 is supported.

• Mint 13 no longer using NVidia card after restart

  - by GenericUsrnme

  Here's the story; I bought a new graphics card, along with other parts, about a week ago. I put them in, install new drivers everything's working fine. Now after a restart I boot into some lovely 1024x768 resolution with only one screen on. I check in the NVidia X Server settings to see if my screen was changed there, there's nothing there except Application profiles and nvidia-settings. I check hardinfo to see if the card is actually recognised; VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1) (prog-if 00 [VGA controller]) I don't really know much about the graphics end of things so I'm not sure what I should be doing here to fix this, I don't even know what I should be looking FOR even, so any help is much appreciated! Thanks in advance

• Nautilus uses different permissions for mounted drives

  - by farhad0011

  I've written two bash scripts to give read-only or read/write access to my NTFS partition: read-only access: sudo umount /media/Data_Drive/ sudo mount -t ntfs-3g -o ro,user,auto,nls=utf8,umask=0000,uid=1000 /dev/sda2 /media/Data_Drive read/write access: sudo umount /media/Data_Drive/ sudo mount -t ntfs-3g -o rw,user,auto,nls=utf8,umask=0000,uid=1000 /dev/sda2 /media/Data_Drive It works perfectly if I only use terminal to work with the files. It also works with Nautilus in read-only mode but not in the read/write mode. In fact, Nautilus gives me an error when I try to copy a file to Data_Drive saying "The destination is read-only". More funny, when I look at the permissions (by right-clicking on Data_Drive and then properties-permissions) I have all the required permissions to write a file in Data_Drive! I am so confused why Nautilus behaves strangely. I appreciate if anybody could solve the mystery!

• Why does 12.04 try but fail to hibernate, even after I enabled hibernation?

  - by Roger Davis

  Regarding the below (-----) info from another post, my system will try (as is said below) to hibernate, but it won't get all the way there. Hard drive activity stops, but it does not shut down. If I turn the power off, then back on, it will start, but I have to "restore previous session" in the browser and other open apps don't restart, with the accompanying hassle. So because it tries, will the suggested fix then cause it to work correctly, or is the literal "try" not really what he means?!? PLEASE NOTE - this is a desktop system, not a laptop. Before enabling hibernation, please try to test whether it works correctly by running pm-hibernate in a terminal. The system will try to hibernate. If you are able to start the system again then you are more or less safe to add an override. To do so, start editing sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla Fill it with this [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes Save by pressing Ctrl-O and exit nano by pressing Ctrl-X Restart and hibernation is back!

• Manually activate Network Manager Applet

  - by diosney

  The issue I've is that when I connect via modem through gnome-ppp the Network Manager Applet don't detect a connection and don't let me use the configured VPNs via its interface. How Can I manually activate the Network Manager Applet? What I need is to enable the Network Manager apple in order to use the "VPN Connection" section of the GUI. When I don't have an ethernet cable connected and I connect through a modem the Network Manager applet doesn't enables itself, it is like if don't recognizes the ppp0 interface. My question is: there is a way to force the Network Manager GUI indicator to make it "alive"/"up"/"enabled" in order to use the "VPN Connections"section? Thanks in advance.

• 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.

• 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 :).

• Will the netinstall (minimal) work with a USB cellular modem?

  - by Z9iT

  Installing Ubuntu minimal is extremely easy when the system has a LAN card and connected to internet via Cable & Router... I Recently came across a situation where I needed to install Ubuntu Minimal on a system which wash not having a LAN card and cable internet anywhere around... The only access to the internet was through a USB Plug n Play Data-Card Modem. May anyone suggest something so that I may install Ubuntu Minimal using USB Modem as the only source of Internet, if it's possible at all?? (This relates to Ubuntu 12.04 in specific)

• thunderbird-bin causing CPU (core) lockup (12.04, 64bit, up-to-date)

  - by david6

  I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice?

• How can I get my mysqld-swamped CPU under control?

  - by Shay Guy

  I was AFK for about 24 hours and came back to find gnome-system-monitor saying all four CPU cores on my laptop were running at full throttle. mysqld is taking up more than one full core; when I tried to end the process, it restarted with a new PID. Then there's ksoftirqd/0-3, which apparently has something to do with interrupts, but I can't tell from Google what I'm supposed to do with those four particular processes. They're taking up a quarter or more of my processor cycles. Then there's Chrome, but I can probably handle that on my own -- how do I cool down the other processes giving me problems?

• Mounting Samba share whenever it's available, unmounting when it's not

  - by Laurynas Biveinis

  I am trying setup permanent samba share mounts. That's not too hard using these instructions. But, I want them to Automatically remount whenever I join the network where these shares are available. Automatically unmount (or make access requests fail immediately instead of hanging) whenever I leave the network, i.e. avoid this automatically. Googling suggests that AutoFS might be helpful. I gather it takes care of the 1. above but I am not sure about the 2. The other questions about automated Samba mounts, i.e. How to mount a samba share permanently?, do not seem to address automatic remounts/unmounts, so I think this is not a duplicate. Thanks.

• Is there an open source alternative to "Adobe Digital Editions"?

  - by soulsource

  For the moment I run Adobe Digital Editions under Wine to download ebooks burdened with ditigal restriction management. I only use it to open .acsm files supplied by ebook-shops, which contain authentication information required to download the actual DRM'ed ebook files, which I then transfer to my reader-device with calibre. My question is, if there exist open source alternatives to Adobe Digital Editions. They don't need much functionality. I just want to put the .acsm-file in and get the .epub out (no, I don't want to remove the drm, that'd be illegal afaik).

• 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....

• SSD options in /etc/fstab stop machine from booting

  - by nbubis

  I just recently installed 12.10 on a new Lenovo T430, and added these options in \etc\fstab: discard, relatime To \sda1 on which \ is installed. When I rebooted, I got an error claiming that it couldn’t read \, and got thrown into a read-only shell, which necessitated booting from a rescue disk to revert to the original fstab. So: What are the correct options for SSD, and how can I make sure I won't get locked out of the system again?

• Ubuntu Installer offers to show differences, then doesn-t

  - by R B

  When I was installing updates under 12.04 LTS today, the ubuntu installer warned that there were differences between the local copy of smb.conf and that in the installer package. It offered me a drop/down list of options. I chose one which reads something like "show differences side by side" and clicked the only available button (other than help, I think it was labelled continue) The installer then proceeded with updates and asked for a reboot. Even after rebooting, no comparison was shown. How can I find out now whether I still have my previous smb.conf or the one from the installer, and what the differences are?

• ProStar gaming laptop, which had Ubuntu 10.10, won't boot past Grub. Thoughts?

  - by Richard Zak

  At work we have some high-end gaming laptops we use for their dual GPUs. The machines have second generation i7 CPUs, and came with Windows 7. On most of them I installed Ubuntu 10.10, and all was fine. There were two laptops that I wanted to repurpose and wanted to reinstall the OS. It boots the CD (burned Ubuntu installation CD, I've tried 10.10, 11.10, and 12.04, as well as CentOS 6), and when Grub tried to boot the kernel, I just get a cursor blinking in the upper left corner of the screen. I tried the disabling of ACPI and the other items in the advanced menu, but nothing works. I could still boot to the current Linux installation though. I was able to install Windows 7 again, and use WUBI, but I think that works because it uses the Windows bootloader and not Grub. How could it have worked before and not now? I have confirmed that the CD is fine, as are the hard drive and CD drive. I also had the same problem with Debian, and had to boot through Windows 7 to install it.

• 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.

• How do I get my folders back on my desktop?

  - by Christopher Allen

  Using the 12.04 version. This morning the Update Manager popped up, I clicked it and it said some items will be un-installed and some will be upgraded and new ones will be installed. I did it and restarted. On restart, I entered my password about 5 times and it said it was incorrect. I changed the shell from Gnome to Ubuntu and logged on then changed it back to Gnome and I was able to log on. However, all my folders on the screen are gone but they appear under Desktop in the Home folder. How do I get then back on the screen?

• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

  Problem: MacBook hard drive crashed and is ruined.
