  • Deleted some files from home folder

    - by narendra shah
    I have recently installed Ubuntu for the first time in my life. So I am fairly new to it. I have deleted some files from my home folder. But now the problems have started. The system volume automatically reduces to zero. Further, as soon as I restarted my system, my panel settings we restored to default. When I right click in my home folder, it gives an option of 'restore missing files' but I am not able to restore them. Please guide me how to restore them. Thanks Narendra

  • How does one find out which application is associated with an indicator icon?

    - by Amos Annoy
    It is trivial to do this in Ubuntu 10.04. The question is specific to Ubuntu 12.04. some pertinent references (src: answer to What is the difference between indicators and a system tray?: Here is the documentation for indicators: Application indicators | Ubuntu App Developer libindicate Reference Manual libappindicator Reference Manual also DesktopExperienceTeam/ApplicationIndicators - Ubuntu Wiki ref: How can the application that makes an indicator icon be identified? bookmark: How does one find out which application is associated with an indicator icon in Ubuntu 12.04? is a serious question for reasons & problems outlined below and for which a significant investment has been made and is necessary for remedial purposes. reviewing refs. to find an orchestrated resolution ... (an indicator ap. indicator maybe needed) This has nothing to do (does it?) with right click. How can an indicator's icon in Ubuntu 12.04 be matched with the program responsible for it's manifestation on the top panel? A list of running applications can include all processes using System Monitor. How is the correct matching process found for an indicator? How are the sub-indicator applications identified? These are the aps associated with the components of an indicators drop-down menu. (This was to be a separate question and quite naturally follows up the progression. It is included here as it is obvious there is no provisioning to track down offending either sub or indicator aps. easily.) (The examination of SM points out a rather poignant factor in the faster battery depletion and shortened run time - the ambient quiescent CPU rate in 12.04 is now well over 20% when previously, in 10.04, it was well under 10%, between 5% and 7%! - the huge inordinate cpu overhead originates from Xorg and compiz - after booting the system, only SM is run and All Processes are selected, sorting on %CPU - switching between Resources and Processes profiles the execution overhead problem - running another ap like gedit "Text Editor" briefly gives it CPU priority - going back to S&M several aps. are at the top of the list in order: gnome-system-monitor as expected, then: Xorg, compiz, unity-panel-service, hud-service, with dbus-daemon and kworker/x:y's mixed in with some expected daemons and background tasks like nm-applet - not only do Xorg and compiz require excessive CPU time but their entourage has to come along too! further exacerbating the problem - our compute bound tasks no longer work effectively in the field - reduced battery life, reduced CPU time for custom ap.s etc. - and all this precipitated from an examination of what is going on with the battery ap. indicator - this was and is not a flippant, rhetorical or idle musing but has consequences for the credible deployment of 12.04 to reduce the negative impact of its overhead in a production environment) (I have a problem with the battery indicator - it sometimes has % and other times hh:mm - it is necessary to know the ap. & v. to get more info on controlling same. ditto: There are issues with other indicator aps.: NM vs. iwlist/iwconfig conflict, BT ap. vs RF switch, Battery ap. w/ no suspend/sleep for poor battery runtime, ... the list goes on) Details from: How can I find Application Indicator ID's? suggests looking at: file:///usr/share/indicator-application/ordering-override.keyfile [Ordering Index Overrides] nm-applet=1 gnome-power-manager=2 ibus=3 gst-keyboard-xkb=4 gsd-keyboard-xkb=5 which solves the battery ap. identification, and presumably nm is NetworkManager for the rf icon, but the envelope, blue tooth and speaker indicator aps. are still a mystery. (Also, the ordering is not correlated.) Mind you, it was simple in the past to simply right click to get the About option to find the ap. & v. info. browsing around and about: file:///usr/share/indicator-application/ordering-override.keyfile examined: file:///usr/share/indicators file:///usr/share/indicators/messages/applications/ ... perhaps?/presumably? the information sought may be buried in file:///usr/share/indicators A reference in the comments was given to: What is the difference between indicators and a system tray? quoting from that source ... Unfortunately desktop indicators are not well documented yet: I couldn't find any specification doc ... Well ... the actual document https://wiki.ubuntu.com/DesktopExperienceTeam/ApplicationIndicators#Summary does not help much but it's existential information provides considerable insight ...

  • Terminal Errors/Package Erros

    - by Bryan
    After running some updates a week ago or so, I've noticed that after any installations via the Ubuntu Software Center or any installed in the GUI have given an error message stating that there was a package error. Also any installations done through the terminal have given the E: Sub-process /usr/bin/dpkg returned an error code (1) message at the end of each install. Oddly, the software is still installed and seems to function properly. Is there any way to get rid of this? I've tried to run apt-get autoclean as recommended on another site, but this doesn't seem to work. I'm fairly new to Linux/Ubuntu, just FYI.

  • Port listening on localhost:8000 but not on ip:8000

    - by Marionette
    Hello I'm running a web application on port 8000. When I access it from the host server localhost:8000 it responds ok, 127.0.0.1:8000 also works, but 192.168.1.7:8000 does not work. 192.168.1.7 is the ip of my server. Also if i try to go to another web application running on port 80 it works 192.168.1.7 I enabled ufw firewall and set ufw default allow. I am using ubuntu server 12.04 Any suggestions on why I can't get to my app on port 8000 using the ip-address:8000? Thanks in advance!

  • Can't build gcc anymore since upgrade to 11.10

    - by Raphael R.
    On Monday I've upgraded to from Ubuntu 11.04 (my initial installation) to 11.10 and now I can't build gcc from source anymore. Since I forgot to uninstall the gcc package before the upgrade, Ubuntu replaced my 4.7.0 compiler with it's stable 4.6.1. So I tried to build the SVN sources again, but it fails. I've most recently tried it with SVN revision 180193. After some time, the build fails with the following message: /home/raphael/devel/gcc/build/./gcc/xgcc -B/home/raphael/devel/gcc/build/./gcc/ -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -isystem /usr/i686-pc-linux-gnu/include -isystem /usr/i686-pc-linux-gnu/sys-include -g -O2 -O2 -I. -I. -I../../src/gcc -I../../src/gcc/. -I../../src/gcc/../include -I../../src/gcc/../libdecnumber -I../../src/gcc/../libdecnumber/bid -I../libdecnumber -I../../src/gcc/../libgcc -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -I. -I. -I../.././gcc -I../../../src/libgcc -I../../../src/libgcc/. -I../../../src/libgcc/../gcc -I../../../src/libgcc/../include -I../../../src/libgcc/config/libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS -DUSE_TLS -o _ashldi3.o -MT _ashldi3.o -MD -MP -MF _ashldi3.dep -DL_ashldi3 -c ../../../src/libgcc/../gcc/libgcc2.c \ -fvisibility=hidden -DHIDE_EXPORTS In file included from /usr/include/stdio.h:28:0, from ../../../src/libgcc/../gcc/tsystem.h:88, from ../../../src/libgcc/../gcc/libgcc2.c:29: /usr/include/features.h:323:26: fatal error: bits/predefs.h: File or directory not found. I've cofigured it with: ~/devel/gcc/build$ ../src/configure --prefix=/usr --enable-languages=c++ And make it with: ~/devel/gcc/build$ make -j4 Just to be sure, I did a rm -rf * in the build directory in case there's some broken stuff inside. Didn't help, though. That's the backstory. I tried to fix it and searched for the bits/predefs.h. It's inside /usr/include/i386-linux-gnu. I temporarily fixed the problem by doing ~/devel/gcc/build$ C_INCLUDE_PATH=/usr/include/i386-linux-gnu make -j4 Which is only temporary because now gcc complains that it can't find crti.o. Which i can find in /usr/lib/i386-linux-gnu. Now i could also set C_LIBRARY_PATH - actually it doesn't work - but I feel like I'm fighting the system here. Also, even if it succeeds, my newly built compiler would also not know about the i386-linux-gnu stuff. So I would have to set C_LIBRARY_PATH and C_INCLUDE_PATH before every build of every project I have. I could add it to my .bashrc but that subverts the system even more. So, how do I tell the build process: That there are additional include/lib directories, and That it should build a gcc which respects them too? Edit: I forgot to include the command which causes the above error message. Also I can think of another solution: Copy the stuff from /usr/include/i386-linux-gnu to /usr/include (same thing for /usr/lib/i386-linux-gnu to /usr/lib). But that doesn't feel right, either. Finally, the system's gcc 4.6.1 can compile other applications just fine, except mine, which use C++11 features not present in the 4.6 series.

  • How do I make changes to /proc/acpi/wakeup permanent?

    - by Jolan
    I had a problem with my Ubuntu 12.04 waking up immediately after going into suspend. I solved the problem by changing the settings in /proc/acpi/wakeup, as suggested in this question: How do I prevent immediate wake up from suspend?. After changing the settings, the system goes flawlessly into suspend and stays suspended, but after I wake it back up, the settings in /proc/acpi/wakeup are different from what I set them to. Before going to suspend: cat /proc/acpi/wakeup Device S-state Status Sysfs node SMB0 S4 *disabled pci:0000:00:03.2 PBB0 S4 *disabled pci:0000:00:09.0 HDAC S4 *disabled pci:0000:00:08.0 XVR0 S4 *disabled pci:0000:00:0c.0 XVR1 S4 *disabled P0P5 S4 *disabled P0P6 S4 *disabled pci:0000:00:15.0 GLAN S4 *enabled pci:0000:03:00.0 P0P7 S4 *disabled pci:0000:00:16.0 P0P8 S4 *disabled P0P9 S4 *disabled USB0 S3 *disabled pci:0000:00:04.0 USB2 S3 *disabled pci:0000:00:04.1 US15 S3 *disabled pci:0000:00:06.0 US12 S3 *disabled pci:0000:00:06.1 PWRB S4 *enabled SLPB S4 *enabled I tell the system to suspend, and it works as it should. But later after waking it up, the settings are changed to either: USB0 S3 *disabled pci:0000:00:04.0 USB2 S3 *enabled pci:0000:00:04.1 US15 S3 *disabled pci:0000:00:06.0 US12 S3 *enabled pci:0000:00:06.1 or USB0 S3 *enabled pci:0000:00:04.0 USB2 S3 *enabled pci:0000:00:04.1 US15 S3 *enabled pci:0000:00:06.0 US12 S3 *enabled pci:0000:00:06.1 Any ideas? Thank you for your response. Unfortunately it did not solve my problem. all of /sys/bus/usb/devices/usb1/power/wakeup /sys/bus/usb/devices/usb2/power/wakeup /sys/bus/usb/devices/usb3/power/wakeup /sys/bus/usb/devices/usb4/power/wakeup as well as /sys/bus/usb/devices/3-1/power/wakeup are set to disabled, and the notebook still wakes up by itself right after going to sleep. The only thing it seems to react to are the settings in /proc/acpi/wakeup, which keep changing (resetting) every time i power off/restart my notebook.

  • Display clock frequency per core using Conky

    - by cfbaptista
    I am using Conky to display a lot of information of my system. I managed to display the load percentage per core. But I do not know how to display the clock frequency of each core. What I have now is: ${font sans-serif:bold:size=8}PROCESSORS ${hr 2}${font} CPU1: ${cpu cpu1}% $alignr ${freq} MHz $alignr ${cpubar cpu1 8,60} CPU2: ${cpu cpu2}% $alignr ${freq} MHz $alignr ${cpubar cpu2 8,60} CPU3: ${cpu cpu3}% $alignr ${freq} MHz $alignr ${cpubar cpu3 8,60} CPU4: ${cpu cpu4}% $alignr ${freq} MHz $alignr ${cpubar cpu4 8,60} CPU5: ${cpu cpu5}% $alignr ${freq} MHz $alignr ${cpubar cpu5 8,60} CPU6: ${cpu cpu6}% $alignr ${freq} MHz $alignr ${cpubar cpu6 8,60} CPU7: ${cpu cpu7}% $alignr ${freq} MHz $alignr ${cpubar cpu7 8,60} CPU8: ${cpu cpu8}% $alignr ${freq} MHz $alignr ${cpubar cpu8 8,60} But this only gives me the global clock frequency and not the individual clock frequency per core. Does someone know how to get the individual clock frequency per core? System information Linux Mint 13 KDE, 64 bit (based on Ubuntu 12.04) Intel i7-2670QM (quad core with multithreading)

  • Empathy chat notification

    - by user3215
    I am using Empathy IM Client for my google hosted mail domain on 9.04, 9.10, 10.04 desktops. I could able to chat from the google mail chat to Empathy and I have set empathy notification to get notified when a message is received and it pops up(not always, don't no why). Whenever it pops up, it show the complete message of the sender which I don't like/want the message to be revealed to everyone whoever looks at my desktop. Is there anything I could do so that the actual message is not shown whenever empathy pops up instead showing any message something similar to "You have got a new message"?.

  • Installing CUDA on Ubuntu 12.04 with nvidia driver 295.59

    - by johnmcd
    I have been trying to get cuda to run on a nvidia gt 650m based laptop. I am running Ubuntu 12.04 with the nvidia 295.59 driver. Also, my laptop uses Optimus so I have install the driver via bumblebee. Bumblebee is not working correctly yet -- however I believe it is possible to install CUDA independently. To install CUDA I have followed the instructions detailed here: How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? However I am still running into problem building the sdk. I made the changes specified at the above link in common.mk, but I got the following (snippet) from the build process: make[2]: Entering directory `/home/john/NVIDIA_GPU_Computing_SDK/C/src/fluidsGL' /usr/bin/ld: warning: libnvidia-tls.so.302.17, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libnvidia-glcore.so.302.17, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link) /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv018tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv012glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv017glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv012tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv015tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv019tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv000glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv017tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv013tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv013glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv018glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv022tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv007tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv009tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv020tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv014glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv015glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv016tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv001glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv006tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv021tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv011tls' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv020glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv019glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv002glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv021glcore' /usr/lib/nvidia-current/libGL.so: undefined reference to `_nv014tls' collect2: ld returned 1 exit status make[2]: *** [../../bin/linux/release/fluidsGL] Error 1 make[2]: Leaving directory `/home/john/NVIDIA_GPU_Computing_SDK/C/src/fluidsGL' make[1]: *** [src/fluidsGL/Makefile.ph_build] Error 2 make[1]: Leaving directory `/home/john/NVIDIA_GPU_Computing_SDK/C' make: *** [all] Error 2 The libraries that ld warns about are on my system and are installed on the system: $ locate libnvidia-tls.so.302.17 libnvidia-glcore.so.302.17 /usr/lib/nvidia-current/libnvidia-glcore.so.302.17 /usr/lib/nvidia-current/libnvidia-tls.so.302.17 /usr/lib/nvidia-current/tls/libnvidia-tls.so.302.17 /usr/lib32/nvidia-current/libnvidia-glcore.so.302.17 /usr/lib32/nvidia-current/libnvidia-tls.so.302.17 /usr/lib32/nvidia-current/tls/libnvidia-tls.so.302.17 however /usr/lib/nvidia-current and /usr/lib32/nvidia-current are not being picked up by ldconfig.

  • Cannot connect to postgresql on port 5432

    I installed the Bitnami Django stack which included PostgreSQL 8.4.

  • How to make bash quit tab autocompleting hidden directories

    - by Kristopher Micinski
    Most of the time, I don't need autocompletes for my hidden directories. In fact, that's the point of them being hidden! However, annoyingly, bash takes these directories into account when considering tab autocompletion. This is particularly annoying when I have the following scenario: a .svn foler along with a single folder that I want to traverse into by simply pushing tab. (This typically comes up with deep Java packages...) Is there any way to change the default behavior? Worst case scenario I have to type '.' before tab, which seems like a no brainer for my usability.

  • Mounting with Nautilus works but fstab gives "Host is down" error?

    - by Annan
    I'm connecting to my university's VPN so I can connect to the network drive. The VPN seems to be working fine and I can connect to the drive by typing the address into Nautilus and entering my login details: smb://139.___.___.140/home However, this fstab entry doesn't work: //139.___.___.140/home /media/___ cifs domain=CS,username==___,password=___,uid=sai,gid=sai 0 0 Nor does manually mounting it: sudo mount -t cifs //139.___.___.140/home /media/___ -o domain=CS,username=___,password=___,uid=sai,gid=sai,user The only error it gives is: mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) It's obvious the host isn't down since I can view the share from Nautilus. Why is Nautilus mounting it fine but not the normal mount command? What could cause this error?

  • GRUB2 prompt instead of BURG boot screen after mistake during BURG installation

    - by Tomas Lycken
    I just installed BURG, but during the installation I made a mistake: after the package was installed, I got to some command-line based GUI for configuration, where I forgot to mark my (only) hard disk as the boot device before I hit OK. I tried to reinstall (apt-get purge burg && apt-get autoremove followed by apt-get install burg) but I wasn't able to get to the same screen again (I didn't find the GUI). When I now start my computer, I am taken to a GRUB2 prompt and no BURG (or GRUB2) boot menu is shown. Since I don't know any GRUB commands and I am helpless. How do I reinstall GRUB/BURG correctly? Update: I rebooted my computer, and got a BURG prompt (which appears to be the same thing as a GRUB prompt, but if there's a difference I wouldn't know it...). I have booted from a Live USB, but I don't know what to do next. The text above has been updated to reflect this new situation - for the original text, please see the previous versions of this post. (No answers were posted when this was edited...)

  • Error when running binary with root setuid under encrypted home directory

    - by carestad
    I'm using a VPN script for Juniper's Secure Access protocol form here, which executes a binary located under ~/.juniper_networks/network_connect/ncsvc with the following permissions: -rws--s--x 1 root root 1225424 okt. 25 13:54 ncsvc But when I do, I get the following error: ncsvc> Failed to setuid to root. Error 1: Operation not permitted Moving/copying the ~/.juniper_networks folder to e.g. /opt/juniper (with the same owner permissions), I don't get the error. In the forum thread at Ubuntuforums someone pointed out that it's probably because I have encrypted my /home and thus a "problem" with ecryptfs. How can I fix this?

  • ath9k driver does not weak up

    - by shantanu
    I know this is common question but i found no suitable answer, so i am asking this again. I installed ubuntu 11.10. I found the bug for ath9k, so set first network boot from BIOS menu. That's worked. I have upgraded to 12.04 yesterday. Now ath9k is creating problem again. First network boot is still enable. ath9k works at start. But failed(connect again and again) after couple of minutes. dmesg show error that it can not weak up in 500us. So i tried #compat-wireless-3.5.1-1. But result is same.

  • "isolinux.bin is missing or corrupt", when attempting to boot using disk in USB CD DRIVE

    I have an external CD drive which connects to USB. I burned 11.10 Ubuntu image to CD-R. The disk correctly shows me install page when I autoload disk within Windows 7. When I restart to attempt to boot from disk to install Ubuntu I get the following error for a split second before I continues to boot to Windows. "isolinux.bin is missing or corrupt". Clearly my computer knows that this is a Linux disk in the usb cd-drive...What went wrong? edit: I reburned another disk, same error

  • "Never hide" Unity launcher via CCSM & gconf doesn't work

    - by Jim Holman
    All: I am running Unity 3D and I want to set my launcher to never hide. I first ran ccsm, and set "Hide Launcher" to "Never". I rebooted then logged back in and it was still auto-hiding. I then ran gconf-editor, I navigated to /apps/compiz-1/plugins/unityshell/screen0/options and then set launcher_hide_mode to 0. I again rebooted and logged back in. The launcher is still auto-hiding. Checking gconf-editor, launcher_hide_mode is set to 0, but this setting isn't active however. What can I do to get the launcher to Never hide? Thanks, Jim

  • Why is Gnome-Shell thinking my "d" key minimizes all windows?

    - by Limitless
    I am on Ubuntu 12.04 LTS (in gnome-shell) and I am unable to use my "d" key. Regular gnome-2 works perfectly fine, but for some reason I cannot use my "d" key in gnome-3. I recently installed it and have been trying to figure this out, but I have no clue what's going on. I attempted to disable the keyboard shortcut that minimizes active windows, but that did not work. (My only option right now is to use CTRL-V to paste my "d"s.) On top of this, my arrow keys automatically move my windows and I cannot move through text using them. What's going on here, folks?

  • Bootloader error Ubuntu 12.04, system goes to Grub-rescue instead of booting

    - by user83508
    I am trying to install ubuntu 12.04 on my system but it is constantly giving me bootloader install fail error. I have tried to lot to solve this issue but reading articles over the internet but still no gain. Firstly since the bootloader was not getting installed I tried to install it on all the alternative paths given in the installer, failing with I selected install ubuntu without bootloader. Then I tried to manually install bootloader via terminal at try ubuntu via grub-install, but I was not able to do that. Then I tried using boot-repair and it was also not able to install the bootloader because after it my system shows grub-rescue. I tried to use boot-repair and install bootloader on a seperate partition mounted to /boot and still my system is booting and it still shows grub-rescue. The error which my system shows during boot is: Error : no such device : 04ac0510-bd4f-43b8-b885-b885-11c4dec21db8 I am not dual booting and ubuntu is the only OS I am installing. I am using Raid 0 with two blue western digital hard drive so I am not sure whether it is right or not. The details given by boot-repair are in the below mentioned link; http://paste.ubuntu.com/1147208/ Afterwards, I made one more change I installed ubuntu again and this time I installed the bootloader at a different partition on /boot. After this the bootloader error has gone but I am still not able to boot to ubuntu as I get the same error I was getting before. I have not installed dmraid, I feel it is neccessary for Raid0, but I thought ubuntu already has Raid drivers. Moreover in the dmraid installation instructions for 12.04, I used the one for 10.04 and selected to install bootloader at the partitions from the dropdown. This time the installation finished normally without an error but still I am not able to boot my system as the same error shows during booting this time also. Now I am stucked and I have no clue on how I can boot my system. Please tell me how can I boot my system.

  • Persistence problem when installing USB Ubuntu variant using Windows

    - by Derek Redfern
    I'm part of a project called One2One2Go - we're developing a Live USB Ubuntu variant for use in schools in Somerville, MA. We have the project files compiled into an iso, and when installed using the native Ubuntu Startup Disk Creator, the USB works fine. When installed using a tool on a Windows machine (LiLi at linuxliveusb.com or liveusb-creator at fedorahosted.org/liveusb-creator), the USB works, but does not have persistence. This happens even if the creator is specifically set to allocate an area for persistent files. When comparing files on sticks created in Windows or Ubuntu, the one file that is different is syslinux/syslinux.cfg. I have printed the contents of the file below: Installed on Windows: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 Installed on Ubuntu: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 For troubleshooting reasons, I changed the Windows-created syslinux.cfg to match the one created by Ubuntu and persistence worked on it. I think the problem is that on the stick created by Windows, there is no "persistent" flag, but I don't know why. Is this a problem with our disk image or with the creator? How would I go about fixing this problem? Thanks in advance for your help. Derek Redfern
