  • How Do I make an Acer T230H Touchcreen work on Ubuntu 9.10?

    - by N Rahl
    I've done this so far: sudo nano /etc/udev/rules.d/99-touchscreen.rules And added: SUBSYSTEM=="usb", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="usb/quanta_touch" SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="input/quanta_touch" sudo service udev restart then the instructions here: http://ubuntuforums.org/showpost.php?p=8932808&postcount=36 And then added to my xorg conf: Section "InputDevice" Identifier "Acer T230H" Driver "hidtouch" Option "SendCoreEvents" "true" Option "ReportingMode" "Raw" Option "Device" "/dev/usb/quanta_touch" Option "PacketCount" "13" Option "OpcodePressure" "852034" Option "OpcodeX" "65584" Option "OpcodeY" "65585" Option "CalibrationModel" "1" Option "CornerTopLeftX" "0" Option "CornerTopLeftY" "0" Option "CornerTopRightX" "1920" # 1920 for 23" Option "CornerTopRightY" "0" Option "CornerBottomLeftX" "0" Option "CornerBottomLeftY" "1080" # 1080 for 23" Option "CornerBottomRightX" "1920" # 1920 for 23" Option "CornerBottomRightY" "1080" # 1080 for 23" Option "CornerScreenWidth" "1920" # 1920 for 23" Option "CornerScreenHeight" "1080" # 1080 for 23" EndSection Section "ServerLayout" Identifier "Touchscreen" InputDevice "Acer T230H" "SendCoreEvents" EndSection And restarted.

  • Understanding the Linux Root

    - by Zac
    I've been using Linux (Ubuntu) for about 2 weeks now and am still struggling with some basic concept surrounding the root user: (1) Some terminal operations (such as making subdirectories inside a FHS directory such as /opt) require me to prefix the command with sudo - why? I guess what I'm choking on is: if I'm already logged in as a valid system user, why do I have to be a superuser/root in order to modify things that the sysadmin has already deemed me worthy of accessing? (2) Is there a GUI (Gnome, KDE) equivalent to sudo? Is there a way to assume a superuser role through a graphical context, rather than from inside a new shell? (3) I can't access the /root directory logged in as myself... but I installed the system to begin with and was never asked to create a root account! How do I log in as root and gain access to /root?!? Thanks for all feedback & input!

  • Missing APR on apache2 ./configure

    - by arby
    I want to build the latest stable version of apache2. I downloaded the source and put APR & APR-util in the srclib folder, then changed directories to ./srclib/apr and ran: ./configure --prefix=/usr/local/apr sudo make sudo make install This seemed to install APR ok, but when I run ./configure from the apr-util directory, I receive the error: configure: error: APR could not be located. Please use the --with-apr option. Using ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr, the error becomes: checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file. Why can't it find APR?

  • Munin does not show Apache/mySQL stats in web view

    - by Chris
    I'm facing a very strange Problem. I just set up Munin on a fresh Ubuntu slice with a common LAMP Stack. Everything works great, except that Munin does just not show the Apache/mySQL stats in the web view. Everything else in the web view works great, Apache works, mySQL works. I even tried calling the plugins via console: sudo munin-run apache_accesses And it works fine. AFAIK Munin log files are not telling me any problems.. My only hint: when I run munin-run without sudo it gives me a "Permission denied" - could this be the problem?

  • OSX Time Machine: deletion of backup folders

    - by jml
    I saw this question and was hoping that someone could expand upon the chosen answer (which I understood): Can you sudo mv Time Machine backup files as sudo from the trash to their original locations? I have tried doing this as root to no avail (operation not permitted). If not, can you successfully rm them via the trash via the terminal, faster than what the endless 'preparing to empty the trash' dialog suggests, and If you get the files back out of the trash can you tell if they are intact via disk utility (and how) Can you force indexing on a Time Machine drive in the same way that you would a normal drive to rebuild the TM index? I realize that a single answer could clarify all of the above, but I wanted to include details to be clear on what I am asking. Thanks for any help.

  • Install problems with XSendFile on Ubuntu

    - by Dan
    I installed the apache dev headers: sudo apt-get install apache2-prefork-dev Downloaded and compiled the module as outlined here: http://tn123.ath.cx/mod_xsendfile/ Added the following line to /etc/apache2/mods-available/xsendfile.load: LoadModule xsendfile_module /usr/lib/apache2/modules/mod_xsendfile.so Added this to my VirtualHost: <VirtualHost *:80> XSendFile on XSendFilePath /path/to/protected/files/ Enabled the module by doing: sudo a2enmod xsendfile Then I restarted Apache. Then this code still just provides me with an empty file with 0 bytes: file_path = '/path/to/protected/files/some_file.zip' file_name = 'some_file.zip' response = HttpResponse('', mimetype='application/zip') response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name) response['X-Sendfile'] = smart_str(file_path) return response And there is not in the Apache error log that pertains to XSendFile. What am I doing wrong?

    Im on Ubuntu 10.04. I want to execute script on system boot. I added it to rc.local. If I execute rc.local manually it works fine.

    - by gletscher
    Hi I want to write a bash script that when called shuts down another computer on the lan. Maybe using ssh? The other computer is an ubuntu machine.

Also I'm not sure how to obtain the rights for the sudo command, hence how to handle the communication between the server and client from within a bash script. Any suggestions are greatly appreciated.

  • enable/disable ntp service on ubuntu 12.04

    - by ntphelp
    Our application runs on Ubuntu 12.04 Precise. On this server, we have both ntpdate and ntp. How to enable and disable the NTP service on-demand? I tried # sudo update-rc.d -f ntp remove/default and # sudo update-rc.d ntp enable/disable commands, but when I reboot server the ntp service starts running! I suspect ntpdate is starting ntp service on reboot. I removed ntpdate package from one of my experimental server, then ntp didn't start on reboot after issuing: # update-rc.d ntp disable Is there a way to control this? or is there way to permanently disable ntpdate?

  • How do I run a beanshell script on my Mac?

    - by jonalv
    My Ubuntu-friend told me to testrun a Beanshell script by doing: bsh #filename# and when I told him that I don't know what bsh is nor have it he told me: sudo apt-get install bsh Being on a Mac I instead ran: sudo port install beanshell But still no bsh command available. A listing of the package content revealed a jar file named: /opt/local/share/java/bsh.jar but when I try to run that with my script file a complete Window manager written in Java starts up (and does not run the script file btw). Now, clearly I am doing something wrong, I am sure there must be a way of running beanshell scripts on a mac terminal although it does seem more natural for the linux users. What am I doing wrong and what should I do to run that script?

  • ipv6 auto configuration not working in ubuntu natty

    In win7, my computer can automatically get a IPV6 global address and use ipv6 network, but in ubuntu natty, I can't find out how to let stateless configuration work. My network is a university campus network,so I don't need tunnels. I think if one thingg can silently and successfully complished in windows it shouldn't be impossible in linux. I did can manually edit /etc/network/interfaces and use a static ipv6 address, and I can use ipv6 this way, but I just want to use auto-configuration. I found this post: How to disable autoconfiguration on IPv6 in Linux? and try sudo sysctl -w net.ipv6.conf.all.autoconf=1 sudo sysctl -w net.ipv6.conf.all.accept_ra=1 but no luck

When I run sudo mount -a I get the following error: topsy@monolyth:~$ sudo mount -a mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) topsy@monolyth:~$ I followed this guide when setting them up: http://ubuntuforums.org/showthread.php?t=288534 So I tried removing them by doing the reverse, and then rebooting, then adding them again and rebooting.

  • Mac Terminal: changed my shell, now can't start it

    - by kch
    I installed bash 4.0 via MacPorts, then used sudo chsh -s /opt/local/bin/bash my_user to change my shell. Before that I tried just running plain chsh without sudo, but it wouldn't allow me to change my shell to that path. Now when I try to start Terminal I'm getting a message that my shell has an illegal value, so Terminal won't start. I click Quit, and, unsurprisingly but annoyingly, it quits immediately. How do I reset my shell so I can start Terminal again? How do I set my shell to bash installed via MacPorts in a way that it'll work? Why does Terminal think my shell is illegal anyway? Is it siding with the neo-prohibitionists? Mac OS X 10.5.8. Everything super mega up-to-date.

  • Power cut during Ubuntu upgrade to 10.04 - boots to command line, apt-get and dpkg do not work.

    - by Macha
    I was upgrading Ubuntu to 10.04, when a tripswitch tripped, cutting power to the computer. When it was restarted, it booted into a command line prompt. Google tells me to try: sudo dpkg --configure -a This gets me a lot of output that ends with a list of packages. I can't tell you what the output is, as piping the output to more/less does not work (still just all scrolls by and moves to next prompt), and redirecting it to a file just results in an empty file. Google also suggested: sudo apt-get install -f This also didn't work. Is a fresh install the only solution at this point?

  • Start tomcat webapp with root privileges

    - by Hagay Myr
    I built a webapp that uses libpcap (via jpcap). In order to be able to get the network interfaces list or to bind to a network interface, the application (in this case a webaap that runs from tomcat server) must be running with root privileges. During development I simply ran Eclipse with root privileges (sudo eclipse) and my webapp worked just fine with Eclipse's local tomcat server. However, when I try to deploy my webapp to the "real" tomcat server, it isn't working. I Also tried to start the tomcat6 service with sudo and changed the TOMCAT6_USER definition (defined in /etc/init.d/tomcat6) from "tomcat6" to "root" but it made no difference. What should I do to make it work?
