• Is it possible to modify a color scheme and windows decorations in Xfce4?

  - by Juhele

  just testing PCLinuxOS Phoenix XFCE Edition 2011-07 which I would like to install on my grandpa's PC instead older PCLOS 2009 with KDE3 (which is almost impossible to upgrade). The PC is relatively older one (Sempron 2200+ CPU, MSI K7N2GM2 board with integrated GeForce 440MX series graphics, 1GB RAM and 80GB IDE HDD) and I thought that it is too weak for KDE4. I already used Xfce in the past (Sam Linux 2006 and 2007), but in new Xfce4 I am not able to somehow change the windows color scheme and the windows decorations - the settings manager offers me switching between preinstalled themes but it is possible to modify them with some GUI?

• Why does a redirect from a local IP address assume localhost?

  - by Jeremy

  I am developing a web application on my desktop and it is running on port 80. I am able to access the application from my laptop connected to the LAN by entering my desktop's LAN IP address 192.168.1.8. Now, my application sends a redirect after login, but my laptop assumes the final address is localhost/login. If I manually type in the IP address and URI for any page, it shows that I am logged in, so it works as expected. So, why does the redirect assume localhost? Both of my machines are linux-based. The laptop being Chrome OS. I am running nginx which proxies non-static file requests to jetty on port 8080.

• Can't figure out how to make Slitaz USB persistent

  - by Dennis Hodapp

  I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent. One told me to add "slitaz home=usb" to the syslinux.cfg file like this: append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb but it didn't work for me. http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically. custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008) does anyone know the best way to make the USB automatically persistent?

• Is it my motherboard?

  - by jarodrussell

  Early this week my home server (a Linux machine) threw a kernel panic. Yesterday is happened a couple of times. Then all of a sudden, when I plugged a USB stick in to run a memory test, the monitor stopped coming on. Now whenever I turn it on, the system gets power...I heard the drives spin, I see the processor fan spin, and the hard drive light comes on...but nothing happens. I put a video card in the AGP slot, but still nothing. The light on the power button that usually comes on stopped coming on. I took the memory out to see if it would beep, but nothing beeped. It's like it's getting power, but it's not coming on. Does this sound like a motherboard problem to anyone else? I think it is, but a second opinion would be greatly appreciated. Thanks.

• KDE doesn't start up anything else

  - by Shane

  I just installed KDE under Arch Linux. Problem is, nothing is starting up right with it - no window manager, no panels, nothing. All I get is a small terminal window in the bottom right corner of the screen, which I'm assuming is konsole. From that single window I can do things like start kwin or launch programs whose names I happen to know (like chromium or firefox), but I don't have a panel for starting programs or switching between programs. It doesn't matter whether I start kdm through inittab or manually by typing # /etc/rc.d/kdm start. KDM looks great, but once I log in as my normal user I just get a console window with no decoration. Is there a startup script for KDE somewhere that needs to run, and usually has a bunch of programs by default - like a window manager, panels, widgets, and all the normal background programs that run in an ordinary GUI? If so, how can I "restore" the default behavior?

• Where can I configure wireless to be passed on to the Virtualbox guest?

  - by huahsin68

  I have WinXP install in virtualbox which host in Linux. I have a TP-Link (TP-WN321G) USB wifi adapter and have the driver installed inside WinXP. When I plug-in the wifi adapter, there is an option show "Ralink 802.11g WLAN [0101]" in the virtualbox's USB icon, tick on that option, the Device Manager able to detect the hardware which shows TP-Link, but when look into the properties, it says there is no driver was install. I did try to install Ralink driver but still no luck. Just curious why my wifi adapter is TP-Link, but the option show Ralink? May I know how can I emulate the wireless network inside WindowsXP?

• Global hotkeys: songbird on KDE

  - by alpha1

  I'm running songbird on opensuse 11.2 KDE 4.3.1 on my EEE pc. On windows, there is a hotkey thing inside Songbird, so i set META F9,10,11,12 as media keys and it work just fine. On linux, there is not hotkey thing in songbird, and I would like to set those same hotkeys. I've played around with the Amarok Hotkeys, which are now setup that way, and looked in all the KDE shortcuts, but cannot find a way to add a new program and new hot keys. I know its possible, I did it before once, but the KDE shortcut programs have changed and I no longer see the stuff i used to do it before. I'd like to do the same to banshee at some point, but Songbird is the important program. Any Ideas? Any way to set those keys to generic media buttons?

• What does dd conv=sync,noerror do?

  - by dding

  So what is the case when adding conv=sync,noerror makes a difference when backing up an entire hard disk onto an image file? Is conv=sync,noerror a requirement when doing forensic stuff? If so, why is it the case with reference to linux fedora? Edit: OK, so if I do dd without conv=sync,noerror, and dd encounters read error when reading the block (let's size 100M), does dd just skip 100M block and reads the next block without writing something (dd conv=sync,noerror writes zeros to 100M of output - so what about this case?)? And if is hash of original hard disk and output file different if done without conv=sync,noerror? Or is this only when read error occurred?

• Wine not finding some files

  - by Levans

  I'm having strange issues with Wine : If I look a C:\windows\system32\drivers\ in wine explorer, the directory looks empty, while the directory ~/.wine/drive_c/windows/system32/drivers is not. Plus, having the H: drive mapped to my home directory, I can look at H:\.wine\drive_c\windows\system32\drivers and it is not empty, the files are here ! Thus it seems Wine has the rights to access these files. So why don't they appear on the C: drive ? Some of my programs need them. I'm using Gentoo Linux, and Wine is version 1.7.0 compiled with these useflags (from eix) : X alsa cups fontconfig gecko jpeg lcms ldap mono mp3 ncurses nls openal opengl perl png prelink run-exes ssl threads truetype udisks xcomposite xinerama xml -capi -custom-cflags -dos -gphoto2 -gsm -gstreamer -odbc -opencl -osmesa -oss -pulseaudio -samba -scanner -selinux -test -v4l ABI_MIPS="-n32 -n64 -o32" ABI_X86="32 64 -x32" ELIBC="glibc" EDIT: I just updated to wine 1.7.4 and nothing changed.

• Watch Filesystem in Real Time on OS X and Ubuntu

  - by Adrian Schneider

  I'm looking for a CLI tool which will watch a directory and spit out the names of files that change in real time. some_watch_command /path/to/some/folder | xargs some_callback I'm aware of inotify (inotify-tools?) and it seems to be what I need, but I need something that is both Linux (in my case Ubuntu) and OSX compatible. It doesn't need to be lightning fast, but it does need to trigger upon changes (within a second is reasonable). Also, I don't necessarily need the exact CLI program mentioned above. If some underlying tech exists and is easily scriptable on both platforms that would be great too.

• Remote Control Home PC from Corporate Work PC

  - by muncherelli

  Here is my situation: I am currently on a Windows XP workstation at work. I have an android tablet that I use to splashtop into my home PC. I would like to be able to use my work keyboard and mouse to control my home PC while I am splashtop'd into it using my tablet. My work PC is on a corporate LAN, and not on the same network as my tablet. The company I work for provides wifi for personal devices, but they are not accessable to the internal network. I thought about going the Synergy route, however that would require my home PC to be able to connect to my work PC which isn't really possible. The opposite would work though, if I could reverse connect the server to the client, but the Synergy software doesn't really support that. I do have a couple linux boxes running at home, so I can ssh into my home network and tunnel ports via SSH if needed. With what I have, how can I accomplish seamless keyboard and mouse sharing between my work PC and either my home PC or my android tablet?

• Windows 7 wake from sleep and UTC?

  - by Joshua Elliott

  I've been having problems with windows 7 waking from sleep after one minute or so on my laptop. I also have ArchLinux installed on this computer. A while back I tried a registry tweak to get windows to use UTC so it would play nice with Linux. The registry tweak didn't seem to work and my windows clock was always wrong. Today I deleted the registry entry that I added, and the problem with sleeping seemed to go away. Can anyone make sense of this? The registry entry I added was: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation] "RealTimeIsUniversal"=dword:00000001

• Bash & 'su' script giving an error "standard in must be a tty".

  - by sHz

  Folks, I'm having an issue with a bash script which runs a particular command as a different user. The background: Running on a Linux box (CentOS), the script is quite simple, its starting the hudson-ci application. declare -r HOME=/home/hudson declare -r RUNAS=hudson declare -r HOME=/home/hudson declare -r LOG=hudson.log declare -r PID=hudson.pid declare -r BINARY=hudson.war su - ${RUNAS} -c "nohup java -jar ${HOME}/${BINARY} >> ${HOME}/${LOG} 2>&1; echo $! > ${HOME}/${PID}" & This is the bridged version of the script, when run, the script exists with "standard in must be a tty". Any ideas on what I could be doing wrong? I've tried Dr Google and all the advise hasn't helped thus far.

• Tool to make screenshot-based "screencast"

  - by liori

  Hello, I'd like to make a simple animation: some screenshots with added text. Something like screencast, but simpler, no audio... and hopefully very quick to produce--this is my main requirement. Googling for "screencasts" gives me full-blown tools to record video and audio, and I don't need them. I can make screenshots manually, then add text in GIMP... but maybe there is something easier, quicker? Very preferably something that works on Linux.

• "Fuzzy" Display Problems on New OpenSUSE 11.3 Install

  - by Kryten

  Hi, I have a old Desktop that has a new installation of OpenSUSE 11.3 on it. To get straight to the point, whenever I try to start-up OpenSUSE, my display goes "fuzzy" (almost like a badly tuned TV) and sometimes (not always) my monitor goes black and says "Out of Range: 15.6kHz/49Hz": I assumed that this was a driver problem, so I download the drivers from nvidia and ran the shell script, completed and rebooted. Then OpenSUSE failed to boot with something like "nscd failed to start". At that point I decided to re-install and I did, but this time I tried un-checking "Automatic Configuration" to see if that helped. Got through the install and still have a problem. Unfortunately, my Linux troubleshooting skills are non-existent, so has anyone got any ideas on what could be the problem (is it the display driver?) and how I can fix the problem?

• Enabling Compiz Viewport Switcher key bindings

  - by David Moles

  I'm running compiz 0.8.2 with compizconfig on Scientific Linux 6.2 with Gnome 2.28.2. In the compizconfig "General Options" I have "Desktop Size" set as follows: Horizontal Virtual Size: 6 Vertical Virtual Size: 1 Number of Desktops: 1 This gets me the layout I want, i.e. 6 workspaces in a horizontal layout. Ctrl-alt-cursor-keys work fine for switching between them. However, I can't figure out how to get key bindings for specific workspaces. I've tried enabling "Viewport Switcher" in compizconfig, and tried various combinations both in "Number-based viewport switching" and "Go to specific viewport", to no apparent effect. My first thought was that something else was eating the specific key bindings I chose, but I think I've tried every combination of shift, control, alt and super (i.e., the Windows key) by now. I tried setting 6 desktops under "General Options" instead of one desktop with horizontal virtual size 6, but that doesn't seem to make a difference either. What am I missing?

• How can I fix an inconsistent NTFS file system without Windows?

  - by Demetri

  I have a Dell laptop that came with Windows from the factory. Since then, I have installed Linux and replaced the hard drive with an SSD. The NTFS partition is inconsistent (a result of bad sectors on the HDD) and needs to be fixed, but I cannot boot into Windows to run chkdsk. How do I fix this problem? Until I do, I cannot move my NTFS partition to expand space on my root filesystem, which is critically low. EDIT: All of my partitions were cloned from my dying HDD to my SSD via Clonezilla. There are no bad sectors on the SSD, but the NTFS partition is still in an inconsistent state.

• Visual annotator for large images

  - by pts

  I have a few hundred images of 30000 x 10000 pixels in size. Each image has lots of text (rendered as pixels) on it. I'd like to translate all text to another language. I speak both languages, and it's fine for me to translate each phrase manually. I need an image editor which can open these images quickly (faster than Inkscape, which needs about 60 seconds to open such an image), lets me zoom and rotate by 90 degrees, lets me erase (i.e. change the color of a selected rectangle to solid white), lets me add text, and lets me save the file as quickly as possible. I'd like to minimize the time I have to wait for the software to load, render and save images. Which is the best program for that on Windows? On Linux?

• Does Wake-on-LAN from power state S5 require any OS configuration?

  - by TARehman

  I am configuring a HTPC which I would like to be able to power on using Wake-on-LAN, from the S5 state (full shutdown, still plugged in). The system is running Linux Mint 14 Cinnamon. I'm getting some conflicting information in my searching on the Net. I am not concerned with using WoL to change the state from standby or hibernate to on. Because of the current interface to our TV, the system must be either turned on or turned off. So, basically, this system will cycle from S0 to S5, and from S5 back to S0, and so on. Some tutorials suggest that I need to use ethtool to configure things after enabling WoL in my BIOS, but my understanding is that doing an S5 - S0 power on only requires the BIOS to be configured (since when the computer is in state S5, the OS hasn't even been loaded anyway). Can I use WoL with only the BIOS configured to go from state S5 to S0, or will I need to configure the OS as well?

• What is fastest way to backup a disk image over LAN?

  - by David Balažic

  Sometimes I boot sysrescd or a similar live linux on a PC to backup the hardrive over local network to my server. I noticed many times, that the transfer speed is not optimal (slower than HDD and network speed). Any rules of thumb what to do and what to avoid? What I typically do is something like: dd bs=16M if=/dev/sda | nc ... # on client nc ... | dd bs=16M of=/destination/disk/backup1 # on server I also "throw" in lzop (other are way too slow) and sometimes on the fly md5sum calculation (both of uncompressed and compress source). I try to add (m)buffer (or other alternatives) to improve throughput (and get a progress indicator). I noticed that even with enough free CPU, adding commands to the pipeline slows things down. Typically the destination is on a NTFS volume (accessed via ntfs-3g, with the _big_writes_ option).

• Can Autodesk Flame run with an nVidia Quadro FX3800 SDI and output to preview through SDI???

  - by cragno

  I am running on Linux RHEL 4.3, DKU 5.0.1. Everything seems to be ok on the xorg.conf and init.cfg, but when I start my projects and Flame enables output to preview I start having preview on my SDI monitor and stop seeing on my main monitor (which is connected to the DisplayPort). Could it be posible that Flame needs Quadro FX4x00/5x00 series with dual DVI to output both monitors?? Cause the FX3800 has only one DVi (which is connected to the SDI card) and 2 DisplayPorts as additional output monitors. Anyone knows a config or workaround this problem?? Thanks ahead!!!

• Are there any command line utilities which can calculate and/or limit how fast a pipe is running?

  - by stsquad

  I'm doing some basic stress testing of a Linux kernel network IWF with netcat. The set-up is fairly simple. On the target side: nc -l -p 10000 > /dev/null And on my desktop I was running: cat /dev/urandom | nc 192.168.0.20 10000 I'm using urandom for some poor-mans fuzz testing. However I find that even at this rate I can break something quite quickly. EDIT So I've been playing with trickle to rate limit how fast I'm generating data: cat /dev/urandom | trickle -u 10 nc 192.168.0.20 10000 But it's hard to tell if this is working. What would be really useful is a the pv equivilent of trickle that can work with pipes.

• Why can't mplayer/libdvdcss/whatever play my DVDs?

  - by che

  To put it bluntly, mplayer is unable to correctly play video DVDs. It seems to correctly find the title and everything, but the picture is broken or not displayed at all, with messages like: a52: CRC check failed! a52: error at resampling [mpeg1video @ 0xa8d840]sequence header damaged [mpeg1video @ 0xa8d840]Missing picture start code Now, this all is on amd64 Gentoo Linux system. I believe the problem is not in mplayer itself, since the playback also breaks in VLC or when i copy the VOBs via vobcopy and try to play them afterwards. I use libdvdcss-1.2.10 and libdvdread-4.1.3_p1168 (current stable in Gentoo), and tried previous versions of both libs, but it didn't change a thing. The DVDs I have tried play fine in regular DVD player or on a Windows laptop. I remember the playback used to work about a year ago and I don't know what to try next. Any hints would be welcome.

• Gnome 3 - Unable to change date and time

  - by Chris Harris

  I am running Arch Linux with Gnome 3. Unfortunately, although my time and date settings in /etc/rc.conf show that HARDWARECLOCK='UTC' and TIMEZONE='America/LosAngeles'. I continue to get the timezone of Europe/London. If I try to change the date and time via the GUI. It requires root access. After authorizing root access, the date and time may be changed; however, after closing the GUI window, it automatically reverts back to the previous incorrect timezone. I am able to use pool.ntp.org in order to sync my time to the correct one; however, this works only for the current session and is not fixed. This solution is inconvenient since there is not always network access. What other solutions are available for this problem?
