  • How can I set a spin button?

    - by espectalll123
    I've done some spin buttons with Glade for my Python/GTK3 app, but I don't know how to set things like default, lower or higher value. How can I do it? Using the following things for development: Python 2.7.3 GTK 3 Glade 3.12.1 1) I need to change things from script, as I need to set default value and maximum value as a variable; 2) I saw the PyGTK documentation before, it's not working for GTK3; 3) please don't direct me to the GTK3 docummentation... I can't understand it :P

  • Remote reboot over ssh does not restart

    - by Finn Årup Nielsen
    I would like to remotely reboot my Ubuntu 12.04 LTS server via ssh. I do sudo reboot and I loose connection and the server connection does not reappear. It does not ping. When I go the the physical computer with a screen attached I see a black screen and hear that the server is still on. I do a hard power off (press power on button for a few seconds) and the server halts. After I press power on the server boots with no problem. As far as I remember the remote reboot has previously worked on that server. I wonder if sudo reboot & will help? I suppose I could also try sudo shutdown -r and see if that does any difference. I have listed an excerpt of /etc/log/syslog below. The last thing it records is the stopping of the logging. Oct 24 10:14:49 servername kernel: [1354427.594709] init: cron main process (1060) killed by TERM signal Oct 24 10:14:49 servername kernel: [1354427.594908] init: irqbalance main process (1080) killed by TERM signal Oct 24 10:14:49 servername kernel: [1354427.595299] init: tty1 main process (1424) killed by TERM signal Oct 24 10:14:49 servername kernel: [1354427.637747] init: plymouth-upstart-bridge main process (20873) terminated with status 1 Oct 24 10:14:49 servername kernel: Kernel logging (proc) stopped.

  • AceCypher is an Addictive Cypher Slide Puzzle Game

    - by Akemi Iwaya
    Are you ready for a game that will test your logical thinking skills while providing hours of fun? Then you may want to have a look at this awesome cypher slide puzzler! AceCypher is great puzzle game for those times when you only have a few minutes to play or want a fun way to pass the time while relaxing. The overall premise and style of game play for AceCypher is simple. You move individual rows (left, right) or columns (up, down) one space at a time in order to shift the positions of numbers on the game board through ’round-a-bout’ trading. The goal is to make the four numbers in the red square match the code shown in the upper right corner (including positions). Sounds simple so far, right? But the challenge comes from the random boards you will be given to work with…some will not be too hard to solve while others will tax your brain (and patience!) quite well.

  • Package management fails in update-manager with gzip problems and compilation errors. U12.04LTS

    - by HarveyP
    Similar to but not the same as Package management system corrupted. Cannot install or remove packages. U12.04LTS (an earlier problem) with package management system. Followed all of L. D. James suggestions in his answer to no avail. This time as well as the gzip error I am also getting compilation errors. The difference may be due to a lack of compilation in my earlier problem so it may be the same error. The packages concerned are enumerated in the output from update-manager below. Also included below that is the output from apt-get -f install apt-get autoremove gives same output. Tried update without SSL updates - 9 to install and got "Unhandled Error in aptdaemon". Output number 3 below. One at a time - output 4 - is for firefox, first in the list of packages. Falls over at libssl1.0.0 despite deselection of it from update ... Tried apt-get install --reinstall dpkg which succeeded, apt-get install --reinstall tar and apt-get install --reinstall gzip both of which failed at libssl1.0.0 as ever. (as suggested by Subv3rsion elsewhere in this forum) Now cannot apt-get update with complete success even after changing server and apt-get clean - output number 5 below ... 1).

  • Is my computer slow due to lack of swap

    - by Kristian Jensen
    A few months ago, I installed Ubuntu 12.04 alongside with Windows 7 on my Asus EEE-PC 1015bx. It has a tendency of freezing and when trying to investigate I found that a swap partition of only 256 MB had been created. The Asus EEE-PC 1015bx is born with 1 GByte RAM only and it is not possible to add further or exchange the existing 1 GByte with a larger card. When looking at the system monitor, it looks like all swap is being utilized along with 70-75% of the RAM, even with very few applications running. Can the lack of much swap space be the reason for my computer running slowly and at times freezing? How can I add a swap partition? Or should I add a swap file instead? At the moment, I see two partitions when viewing the system monitor: one 28.6 GByte ext4 partition which must be the one containing Ubuntu and one 100 GByte fuseblk partition which I assume is the one holding Windows. It shows that I have 18.6 GByte free space on the ext4 partition. Can I "take a bite" from the ext4 partition and convert this into a swap partition? I was thinking something like 3 GBytes for swap considering my limited RAM. I hope that someone can guide me through. Thank you. 20th Oct 2012 - Further details Thank you for below answer which I find very useful. I am certainly considering switching to one of your suggested shells as I can see from the Internet that many have posted that these require much fewer resources than ubuntu. It seems to me that lubuntu is the perfect match for my very limited computer. I will have to wait a few days, though, as I am presently limited by a very slow and restricted Internet connection via satellite. But will lubuntu install as simply another shell replacing unity or will it replace ubuntu all together? Will the software that I have installed under ubuntu still be accessible in lubuntu? And can I return to ubuntu if required? Regarding the actual question of swap: When I run gparted, it shows me that there is one ntfs partition of 100 GBytes from where it boots and the before mentioned ext4 partition of 28.6 GBytes is not mentioned. Could it be that my ubuntu installation resides inside this 100 GBytes ntfs partiotion? And if so, can I take a bite of this for my swap partition? Realising that gparted is shown in Danish, I hope that you can make out what I mean. System monitoring shows below details: Once again I sincerely hope that you can help. Thank you.

  • Log php errors in ubuntu

    - by resting
    I followed the setup here: Where is the PHP error log When I look into /var/log/php_errors.log, I could see some PHP errors. PHP Warning: file_get_contents(/var/www/...): failed to open stream: No such file or directory in ... But what I'm trying to see is the error when I removed a semicolon from a statement. That error above has no relation to file from where I removed the semicolon so we can just ignore that. When I access the page with the removed semicolon, I get The website encountered an error while retrieving https://myapp/download/decode/testfile. It may be down for maintenance or configured incorrectly. HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request. But no logs in /var/log/php_errors.log. How do I see the error that usually says which line and which file the process failed? The real reason for trying to see the error is because I have a very huge loop, that throws the HTTP 500 error and I can't see the exact error. I'm just simulation with a removed semicolon to test things out. Other settings: error_reporting = E_ALL & ~E_DEPRECATED display_errors = On On Ubuntu 10.04.4 LTS Update Ok, I managed to get the error message to display. Parse error: syntax error, unexpected T_IF in ... However, it's still not logged. It wasn't displaying previously because Cakephp's debug level was at 0. Setting it to 2 displays the message, but no logs.

  • How to make Xbox joypad work with Bastion?

    - by Alistair Buxton
    I have an XBox joypad: Bus 005 Device 004: ID 045e:0289 Microsoft Corp. Xbox Controller S When I start Bastion from the terminal the following is output: Number of joysticks: 1 Number of buttons for joystick: 0 - 10 Number of axes for joystick: 0 - 6 Number of PovHats for joystick: 0 - 1 When I load up the game it displays a message "press any key" and at this point, if I press a button on the joypad it advances to the main menu. However, the up/down/left/right controls do not work and the button will not operate the menu. When I enter the control configuration, the joypad section is disabled and displays a message "joypad not detected." If I enter the control customization and try to reconfigure one of the controls, noises can be heard when pressing joypad buttons, but the input is otherwise ignored. Further information which may or may not be relevant: My controller is an original Xbox controller, not a 360 controller. XNA games on Windows apparently only work with Xbox360 controllers because they use xinput rather than direct input, see eg here. My controller works (almost) properly with MonoGame trunk samples, but Bastion uses a modified MonoGame and crashes when run against trunk, so I can't add debugging to see where the problem is. Bug can also be reproduced with a Xbox 360 wired controller.

  • Fonts look horrible in any java application

    - by Eirik Berg
    All fonts in java applications look horrible. I have seen a few questions about this previously, but they are quite old now(11.04 was the most recent, but that didn't seem to be the same problem). For some reason java applications do not use the system font (Ubuntu 11), but rather some elongated font that doesn't seem to have any anti-aliasing. So what I'm asking is if this is an open bug(couldn't find any on launchpad), something the developers have done wrong, or if there is a way to configure the fonts used in java application. Perhaps this is just a shortcoming of openjdk and I should install the Sun version instead? Attached an image showing jitsi, but the problem is also present in minecraft, my internet-bank and anything else involving java. I'm on 12.04, but since I couldn't find anything on launchpad I'm assuming that isn't relevant. Edit: actually managed to forget the picture... Thanks!

  • How to control CPU frequency

    - by Tim
    I am using CPU Frequency Scaling Monitor 2.30.0 on the panel to show and control CPU frequency. My CPU frequency by default will change according to load. But I want to make CPU work at the lowest level and so I choose 800 MHz in CPU Frequency Scaling Monitor. After a few seconds, however, it automatically changes back to Powersave or Performance mode which has automatic adjustment to CPU frequency. I was wondering how to actually make CPU work at the lowest level? Thanks!

  • LSI SAS 9240-8i on Ubuntu 12.04 Hangs on Modprobe

    - by Francois Stark
    I used the LSI 9240-8i card on a smaller Intel motherboard with no problems in Ubuntu, with ZFS. However, we rebuilt the server to allow for more disks, using the ASROCK X79 Extreme 11 motherboard. It has 7 PCIe slots, and a LSI 2008 on-board. At first I thought the LSI 9240, when plugged in to PCIe, clashed with the on-board LSI 2008. Every time I plugged in the LSI 9240, modprobe would hang. Then I completely disabled the on-board LSI 2008, and the problem persisted. Last night it booted perfectly ONCE - all LSI cards and connected disks visible... However, all subsequent reboots failed. Both LSI cards' bios scans appear and they both see the disks connected to them, but Ubuntu modprobe hangs.

  • Wine / PlayOnLinux dependency issues when trying to install

    - by Glutanimate
    I am curious as to why installing PlayOnLinux entails removing seemingly unrelated packages like google-earth-stable. Is this the expected behaviour? This is the output I get when trying to install playonlinux through apt-get: The following packages were automatically installed and are no longer required: python-scour pax ncurses-term Use 'apt-get autoremove' to remove them. The following extra packages will be installed: binfmt-support fonts-horai-umefont fonts-unfonts-core libcapi20-3 libgif4:i386 libmpg123-0 libodbc1 libpam-winbind ttf-umefont ttf-unfonts-core unixodbc winbind wine wine-gecko1.4 wine-gecko1.4:i386 wine1.4 wine1.4-amd64 wine1.4-common wine1.4-i386:i386 winetricks Suggested packages: libmyodbc odbc-postgresql tdsodbc unixodbc-bin dosbox Recommended packages: gettext:i386 unixodbc:i386 The following packages will be REMOVED: alien cdbs debhelper dh-make dh-translations gettext google-earth-stable intltool intltool-debian lsb-core po-debconf The following NEW packages will be installed: binfmt-support fonts-horai-umefont fonts-unfonts-core libcapi20-3 libgif4:i386 libmpg123-0 libodbc1 libpam-winbind playonlinux ttf-umefont ttf-unfonts-core unixodbc winbind wine wine-gecko1.4 wine-gecko1.4:i386 wine1.4 wine1.4-amd64 wine1.4-common wine1.4-i386:i386 winetricks 0 upgraded, 21 newly installed, 11 to remove and 0 not upgraded.

  • Ubuntu boots to totally blank after I installed some graphic card updates

    - by baboonWorksFine
    I am using Ubuntu 10.04 LTS, dual boot with win7 on ThinkPad T400, I followed Ubuntu update hints and installed some update for my ATI Radeon graphic card, but when I boot to Ubuntu(means I can still load GRUB), the tragedy happened, the screen goes to blank and no matter what key stroke, I can not get any responds, I try to go to text terminal, but impossible! However when I hit the power button, the computer would pop out the Ubuntu shutdown screen briefly and shut down. I figure out I should delete the updates package of my graphic card, but I don't even get a chance to go to text terminal, please help me!

  • Best VNC client for remote desktop assistance?

    - by e.m.fields
    Poll on best VNC / remote desktop software for assisting others on Windows/Mac machines from Ubuntu? I've heard good things about TeamViewer and Fog Creek Copilot, but I'm wondering if the included GNOME Vinaigre VNC client is good enough for this. To specify, I'm looking for best option based on: SIMPLEST ease-of-use for client to download/use on their end. See #1. Works cross-platform I am able to control client's mouse and/or keyboard from remote machine.

  • Brainworkshop won't go fullscreen

    - by user1777025
    I am unable to run brainworkshop in fullscreen mode. After correctly changing the config.ini file to launch the script in fullscreen mode all I get is a window of the same size as before but with no frame or title bar, aligned to the top right (below the menu bar and to the right of the edge of the screen). I tried posting a screenshot but as I'm a new user I wasn't allowed to... I tried looking around in the pyglet files to see if I could find anything that might be causing this but it's all beyond me. Any suggestions? Right after posting this I relaunched the script and now the same borderless, resizeable window is launched aligned to the bottom right hand corner of the screen... I'm running ubuntu 12.04 and brainworkshop 4.8.4.

  • What can I do to give some more love and disk space to my database on Ubuntu?

    - by Yaron Naveh
    I'm new to linux. I've deployed a db to ubuntu server on amazon and found out I'm low on disk space. did df (see below) - and found out that I'm 89% capacity on one file system, but less on others. What does this mean? Do I have a few partitions and can now utilize others besides /dev/xvda1? Also /dev/xvdb seems large, is it safe to put the db in it and only use it? If so do I need to mount it or do something special? $> df -lah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 6.7G 914M 89% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 3.7G 8.0K 3.7G 1% /dev devpts 0 0 0 - /dev/pts tmpfs 1.5G 164K 1.5G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.7G 0 3.7G 0% /run/shm /dev/xvdb 414G 199M 393G 1% /mnt
