• looking for dark, high contrast theme

  - by d3pd

  I am looking for a dark, contrast theme. Most dark, high-contrast themes I have tried do not give sufficient contrast to many edges, such as the edges of buttons, tabs, windows and other borders. Could you recommend themes that would provide such features? Alternatively, could you recommend a guide to changing a fairly dark theme, such as Numix-Cyanogen, such that it would feature light button, tab, window and other borders? Roughly visually, what I mean is to from this: to something like 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?

• Is a disk/ata timeout exception dangerous?

  - by j-g-faustus

  I have a few hard drives in mdadm RAID 5 configured to go to standby after a few minutes of inactivity. (Using hdparm.conf spindown_time.) At irregular intervals I get messages like these in dmesg: [ 1840.251661] ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [ 1840.251722] ata4.00: failed command: SMART [ 1840.251758] ata4.00: cmd b0/d5:01:06:4f:c2/00:00:00:00:00/00 tag 0 pio 512 in [ 1840.251759] res 40/00:14:50:2e:04/00:00:02:00:00/40 Emask 0x4 (timeout) [ 1840.251858] ata4.00: status: { DRDY } [ 1840.251888] ata4: hard resetting link [ 1840.600742] ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1840.601521] ata4.00: configured for UDMA/133 [ 1840.601547] ata4: EH complete [337877.713988] ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [337877.714019] ata4.00: failed command: SMART [337877.714038] ata4.00: cmd b0/d5:01:06:4f:c2/00:00:00:00:00/00 tag 0 pio 512 in [337877.714039] res 40/00:04:90:10:81/00:00:00:00:00/40 Emask 0x4 (timeout) [337877.714089] ata4.00: status: { DRDY } [337877.714107] ata4: hard resetting link [337878.063085] ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [337878.063743] ata4.00: configured for UDMA/133 [337878.063764] ata4: EH complete I think the exception is caused by smartd when a drive does not wake up quickly enough. There are no issues (that I can tell) in accessing the drives normally through the file system - it takes a few seconds longer than normal when they are asleep, but there are no exceptions. Is this something I should worry about, as a potential symptom on something that could corrupt a drive over time? Or can I safely ignore it as part of normal operation? Edit: By request: smartctl -a for sdaand sde, both disks are members of the array. If ata4is the same as scsi-4 then sde is the one that gave the error above, according to /dev/disk/by-path.

• Recovering data from /

  - by Abhijit Gavas

  I accidentally installed Ubuntu to one of my data drives from Windows. The drive was a NTFS drive and contained about 80 GB of important data. The size of the drive is 110 GB. Its new file system is ext4. In an attempt to recover the data, I downloaded foremost and tried the following commands: foremost -i / -o /media/281C8DB01C8D7998/Recovery/ -T -v foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v (sda7 is the drive in question.) It appears that with either command, foremost gets stuck reading some file. Here is the console output: abhi@abi-PC:/dev$ foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Foremost version 1.5.7 by Jesse Kornblum, Kris Kendall, and Nick Mikus Audit File Foremost started at Fri Sep 28 20:58:00 2012 Invocation: foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Output directory: /media/281C8DB01C8D7998/Recovery_Fri_Sep_28_20_58_00_2012 Configuration file: /etc/foremost.conf Processing: stdin |------------------------------------------------------------------ File: stdin Start: Fri Sep 28 20:58:00 2012 Length: Unknown Num Name (bs=512) Size File Offset Comment Killed As you can see I have to kill it from system monitor. This approach does not seem to be working. What else could I try to recover the files? Please help. The files are very important and I will be devastated if I cannot recover them.

• Stuck on Ubuntu startup screen (5 orange bullets)

  - by psyboy14

  I recently download Ubuntu 12.04 LTS onto my Macbook Pro 5-5. Everything worked seamlessly, save for the brightness control. I couldn't change the screen brightness from the hardware buttons, nor from the system preferences. To fix it, I used the instructions here: MacbookPro 5-5 LCD Brightness Control At #2, I restarted my laptop, only to see that it went straight to the Ubuntu Startup Screen, with the 5 orange dots (Usually they all startoff white, then turn orange to indicate progress). From there, I tried controlling the brightness from the keyboard, and it worked, but sadly, my computer is still stuck on the loading screen. (Yes, I have tried manually restarting it) Could you please help? Thank you in advance

• Why ISO master (editor) does not read Windows images

  - by Jacek Blocki

  I have the followjng problem with ISO master software: I try to edit WIndows 7 ISO image $ isomaster windows7.iso The file does open, unfortunately all I get is README with message: This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification. isomaster comes form Ubuntu repository, I am using 12.04. The system has kernel support for UDF installed, I can mount above ISO (mount -o loop) and see its content read only. Any idea how to fix it? Using other than isomaster tool is also an option.

• Dual Boot Ubuntu and Windows 7: BOOTMGR is missing when I tried to boot in Windows

  - by Simon Polak

  So, I don't know what exactly how I managed to delete the MBR record on windows partition. But let me explain what I did next, I ran the ubuntu boot repair tool and now Windows is not even listed in my grub loader. So I went and booted with windows cd and choose repair. Then I ran ubuntu boot repair again via live cd. Here is the log http://paste.ubuntu.com/1426181/. Still no luck. Looks like osprobe can't detect windows on my /dev/sda2 partition. Any clues ? Here is how my partitions look like: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x525400d1 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 509620669 254706911 7 HPFS/NTFS/exFAT /dev/sda3 509622270 976773119 233575425 5 Extended /dev/sda5 509622272 957757439 224067584 83 Linux /dev/sda6 957759488 976773119 9506816 82 Linux swap / Solaris

• Keyboard shortcut: Win key doesn't work for custom commands

  - by Xiè Jìléi

  It's all ok before upgraded from 10.04 to 12.04. It seems all right. In keyboard shortcut window, if I pressed Win+V, it can capture the key combination as Super+V, no problem. I've checked the output from xev utility, the left and right Win keys are translated to Super_L and Super_R correctly. I have found a workaround, though. Using gconf-editor, edit the entries /desktop/gnome/keybindings/*/binding and replace <Super> with <Mod4> for the problem bindings. However Super+... keys do work for most built-in actions such as "switch workspace", they just don't work for custom commands.

• 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.

• How can I assign custom icons to folders?

  - by Frank Souza

  How do I assign custom icons to folders, as well as the default folders Desktop, Downloads, Music, etc.? I know that one way is to assign the properties of folders, but I want to assign icons in the same way that are assigned the default folders, so the custom icons will also appear in the Nautilus bookmarks. I've also seen this question custom icon in "Places" menu <<, but that is not what I seek. UPDATE My main intention is this: I want the markers to display custom icons like the dolphin. I know it's possible, because the folder "Desktop", "Documents", "Music" has its own custom icons in bookmarks. How?

• Wifi speed with driver rtl8187 drops

  - by Peter

  I am using lucid lynx with this USB adapter and drivers rtl8187. When I start a download, it starts at 1500kpbs (if i use "iwconfig wlan0 rate [more than 11MB]" it starts at a lower speed), it transfers a few kbs but then the speed starts to drop constantly and nothing is being transferred. I've also tried the driver r8187, but I have the same speed problem only that with this driver the download starts at only 10kbps, and drops from there. What can I try to identify the cause and fix this problem?

  The desktop does not show after I installed nvidia experimental drivers. I tried nvidia simple proprietary drivers, and they did not work either. Here is how it looks. This is not cropped or any thing. This is how it looks, after the installation of the drivers the desktop resolution decreased from 1440X900 to 1024X768 The desktop only shows desh and panels when I use the open source drivers. Is there any way to fix this so I can get better performance? Thank you in advance.

• After login I only get a terminal window

  - by Ambidex

  First of, let me tell you I'm a n00b at ubuntu. I have updated my Ubuntu mediacenter to a later version of ubuntu, currently at 12.04. I'm working through a lot of updates to get to the latest. But since my first update I got the new login screen (lightdm?) and my autologin wasen't working anymore. So I Googled how I could make lightdm autologin. I've managed this by making my /etc/lightdm/lightdm.conf look as follows: [SeatDefaults] greeter-session=unity-greeter user-session=ubuntu autologin-user=my_user autologin-userutologin-user=-timeout=0 Which seemed to work... But now that it automatically logs in, I seem to get the following type of screen (through nomachine remote desktop client): Sorry... I am unable to post my screenshot here because I do not have the 10 reputation points in askubuntu yet.... darn it... But the screen has a terminal at the top left of the screen (not an actual "window"), and the ubuntu loading screen is still behind it. I've tried running startx as you can see. But, this seems to actually be x server. But if I run unity --reset, it seems that a lot of the desktop gets restored, but... with a lot of errors and warnings and the next time I boot, it's the same story all over again. Also, when I close the terminal window after getting my desktop back, I get thrown back at the login screen. Please bear with my lack of knowledge of ubuntu and it's underlying unix. I thank you in advance.

• How to change keyboard layout?

  - by swedishhh

  I'm on ubuntu 12.04. Recently I bought a cheap apple style bluetooth keyboard. It pairs OK. I paired it with the current 102 key still attached. Anyway I noticed that the character mapping is incorrect. Most keys do not type anything - some keys on the right (k, l, ;') etc give numbers, but that's about it. So I rebooted, with 102 kbd unattached, and the bluetooth keyboard on, ready to connect. After boot at the login screen, the bluetooth keyboard had paired. I typed my password, and it logged in fine!! However after the user login was complete it reverted to the broken behaviour. A glance at the layout chart shows ubuntu thinks I still have the 102 layout, even though it remained disconnected. Any ideas? Thanks, Dave

• Hosting Bazaar shared repositories

  - by Kishor Kundan

  What i want ? We operate in a small team of 9 people including developers, QA and designers. I want to setup a version control. We have a ubuntu (server edition) and i want to host all our repositories there. I have no understanding that even if it is possible. What I have done? We have setup bazaar on all distributions. We are using Bazaar explorer as our gui front-end. The command edition from console isn't very comfortable to all members. We have gone through the manual, but it hasn't been very helpful. Our inexperience being the cause. Team The designers are using windows distribution and developers & QA are using ubuntu distributions. I have googled around and i am really struggling to find a good tutorial for this setup. So any links/guides/leads towards accomplishing the same would be very helpful. While posting links or answer please do consider our inexperience. Thank you !!! cheers

• 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.

• Internal Mic not working on Dell Adamo 13

  - by AFD

  So I'm using Elementary Luna Beta (based on Ubuntu 12.04 LTS) on a spare HDD after successfully using Jupiter release (based on 10.10) for many years. In Jupiter I had my internal mic work out of the box and with Skype installed from deb it was all setup without having to step foot inside the terminal. In Luna Beta the internal mic is not recognised by the OS and so also not recognised by Skype. I believe the hardware is this (from sudo lshw): *-multimedia description: Audio device product: 82801I (ICH9 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=HDA Intel latency=0 resources: irq:46 memory:f8600000-f8603fff As well as this I ran cat /proc/asound/card0/codec* | grep Codec which gave me: Codec: IDT 92HD73C1X5 Codec: Intel Cantiga HDMI How do I tweak Luna to get this hardware working properly? I'm able to switch out my Luna HDD with the Jupiter HDD to help troubleshoot what the differences are between the two and why the more recent OS can't find / use the mic correctly. Thanks in advance for any help you can give.
