  • Need to run a .sh as root on boot or login

    - by Graymayre
    Still new with linux and running ubuntu 12.10 I have a wireless stick (ae2500) which has known issues that has been partially solved using ndiswrapper. However, to use it I must run the same scripts every time I reboot, effectively uninstalling and reinstalling the driver. I made a .sh file to run every time to make it easy, but I must do the sudo login everytime. There are three solutions I am looking for and although not all are necessary to solve this particular problem, I would still like to know them all for learning purposes. run scripts or file.sh on boot (as well as other programs) run scripts or file.sh automatically with root privileges make the install permanent so as not to have to go through the process every time. Any additional information that can help me regarding this that I did not think to ask (including streamlining my commands), or general knowledge, would be greatly appreciated. Following are the contents of the file. I pretty much just made it as I would have entered it. cd ~/ndiswrapper-1.58rc1 sudo modprobe -rf ndiswrapper sudo rm /etc/modprobe.d/ndiswrapper.conf sudo rm -r /etc/ndiswrapper/* sudo depmod -a sudo make uninstall sudo make sudo make install sudo ndiswrapper -i bcmwlhigh5.inf ndiswrapper -l sudo modprobe ndiswrapper

  • Kernel panic on reboot after failed logical volume resize

    - by Derek
    I attempted to do a logical volume resize yesterday using the follwoing commands $sudo pvdisplay "/dev/sda8" is a new physical volume of "113.11 GiB" --- NEW Physical volume --- PV Name /dev/sda8 VG Name PV Size 113.11 GiB Allocatable NO PE Size 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID jwyO1o-b2ap-CW51-kx7O-kf26-arim-SM8V6m $sudo vgextend vg /dev/sda8 sudo vgdisplay vg --- Volume group --- VG Name vg System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 9 VG Access read/write VG Status resizable MAX LV 0 Cur LV 5 Open LV 5 Max PV 0 Cur PV 2 Act PV 2 VG Size 131.74 GiB PE Size 4.00 MiB Total PE 33725 Alloc PE / Size 4769 / 18.63 GiB Free PE / Size 28956 / 113.11 GiB VG UUID AhusW2-pzFv-3W32-mpv2-s5VG-FN7S-kVSadx $sudo lvresize -L +20GB /dev/mapper/vg-var So as you can see, it looks like adding the physical volume to the vg worked, because i see free space available there. When I typed the lvresize command, it never returned. I let this run overnight in the background, but this morning I still couldnt successfully do a "pvdisplay" or "lvdisplay" because I think it was waiting on a lock or something, so the command never returned. When i went to log onto the server's console, I saw a bunch of messages like: rcu_sched_state detected stall on cpu 2 Now when I boot, I get a kernel panic error, and a message about not being able to mount /mapper/vg-root cannot open root device "mapper/vg-root" or unknown_block(0,0) Kernel Panic -not syncing: VFS: Unable to mount root file system on unknown_block(0,0) What should I do to get my system back up and running? Did I attempt to do the logical volume resize correctly? Thanks

  • Automatically triggering standard spaceship controls to stop its motion

    - by Garan
    I have been working on a 2D top-down space strategy/shooting game. Right now it is only in the prototyping stage (I have gotten basic movement) but now I am trying to write a function that will stop the ship based on it's velocity. This is being written in Lua, using the Love2D engine. My code is as follows (note- object.dx is the x-velocity, object.dy is the y-velocity, object.acc is the acceleration, and object.r is the rotation in radians): function stopMoving(object, dt) local targetr = math.atan2(object.dy, object.dx) if targetr == object.r + math.pi then local currentspeed = math.sqrt(object.dx*object.dx+object.dy*object.dy) if currentspeed ~= 0 then object.dx = object.dx + object.acc*dt*math.cos(object.r) object.dy = object.dy + object.acc*dt*math.sin(object.r) end else if (targetr - object.r) >= math.pi then object.r = object.r - object.turnspeed*dt else object.r = object.r + object.turnspeed*dt end end end It is implemented in the update function as: if love.keyboard.isDown("backspace") then stopMoving(player, dt) end The problem is that when I am holding down backspace, it spins the player clockwise (though I am trying to have it go the direction that would be the most efficient at getting to the angle it would have to be) and then it never starts to accelerate the player in the direction opposite to it's velocity. What should I change in this code to get that to work? EDIT : I'm not trying to just stop the player in place, I'm trying to get it to use it's normal commands to neutralize it's existing velocity. I also changed math.atan to math.atan2, apparently it's better. I noticed no difference when running it, though.

  • Connecting to wireless networks from command line

    - by Balaji
    I need to write a shell script which connects to one of the two available wi-fi connections. One is a un secure connection and the other is secure connection. My question has 2 parts- 1.How to connect to the un-secure (un-encrypted and no password required) connection from command line (or by executing a shell script) when I'm connected to the secure connection? I followed the steps in http://www.ubuntugeek.com/how-to-troubleshoot-wireless-network-connection-in-ubuntu.html for in-secure connection. I put all the commands in a script and executed it (I made sure that interface name and essid are correct) - sudo dhclient -r wlan0 - sudo ifconfig wlan0 up - sudo iwconfig wlan0 essid "UAPublic" - sudo iwconfig wlan0 mode Managed - sudo dhclient wlan0 But nothing happens - I'm not disconnected from the current network and connected to the new one 2.When I want to connect to the secure wi-fi network, I understand from http://askubuntu.com/a/138476/70665 that I need to use wpa_supplicant. But I enter a lot of details in the interface when I connect via UI security : wpa and wpa2 enterprise Authentication : PEAP CA certificate : Equifax... PEAP version : automatic inner authentication : MSCHAPv2 username : password : How to use wpa_supplicant to mention all these details in the command line? The conf file network={ ssid="ssid_name" psk="password" } doesn't work for me.

  • Procedure or function has too many arguments specified

    - by bullpit
    This error took me a while to figure out. I was using SqlDataSource with stored procedures for SELECT and UPDATE commands. The SELECT worked fine. Then I added UPDATE command and while trying to update, I would get this error: "Procedure of function has too many arguments specified" Apparently, good guys at .NET decided it is necessary to send SELECT parameters with the UPDATE command as well. So when I was sending the required parameters to the UPDATE sp, in reality, it was also getting my SELECT parameters, and thus failing. I had to add the extra parameters in the UPDATE stored procedure and make them NULLABLE so that they are not required....phew... Here is piece of SP with unused parameters. ALTER PROCEDURE [dbo].[UpdateMaintenanceRecord]        @RecordID INT     ,@District VARCHAR(255)     ,@Location VARCHAR(255)         --UNUSED PARAMETERS     ,@MTBillTo VARCHAR(255) = NULL     ,@SerialNumber VARCHAR(255) = NULL     ,@PartNumber VARCHAR(255) = NULL Update: I was getting that error because unkowingly, I had bound the extra fields in my GridVeiw with Bind() call. I changed all the extra one's, which did not need to be in Update, to Eval() and everything works fine.

  • Correct nvidia+intel graphics setup in 14.04

  • Languages like Tcl that have configurable syntax?

    - by boost
    I'm looking for a language that will let me do what I could do with Clipper years ago, and which I can do with Tcl, namely add functionality in a way other than just adding functions. For example in Clipper/(x)Harbour there are commands #command, #translate, #xcommand and #xtranslate that allow things like this: #xcommand REPEAT; => DO WHILE .T. #xcommand UNTIL <cond>; => IF (<cond>); ;EXIT; ;ENDIF; ;ENDDO LOCAL n := 1 REPEAT n := n + 1 UNTIL n > 100 Similarly, in Tcl I'm doing proc process_range {_for_ project _from_ dat1 _to_ dat2 _by_ slice} { set fromDate [clock scan $dat1] set toDate [clock scan $dat2] if {$slice eq "day"} then {set incrementor [expr 24 * 60]} if {$slice eq "hour"} then {set incrementor 60} set method DateRange puts "Scanning from [clock format $fromDate -format "%c"] to [clock format $toDate -format "%c"] by $slice" for {set dateCursor $fromDate} {$dateCursor <= $toDate} {set dateCursor [clock add $dateCursor $incrementor minutes]} { # ... } } process_range for "client" from "2013-10-18 00:00" to "2013-10-20 23:59" by day Are there any other languages that permit this kind of, almost COBOL-esque, syntax modification? If you're wondering why I'm asking, it's for setting up stuff so that others with a not-as-geeky-as-I-am skillset can declare processing tasks.

  • Difficulty Mounting Volumes on a Partitioned External HD

    - by Todd
    I'm having a great deal of difficulty with an external hard drive. I'm currently running a dual boot system (XP Service Pack 3 and Ubuntu 11.04 Natty Narwahl) on a Dell Inspiron B120. I'm trying to set up a new 80 GB Hitachi external HD. Using GParted, I formatted the drive and set up the partitions. The partitioning scheme is as follows 10GB NTFS Primary, 2GB Linux-Swap Primary, 50GB FAT32 Primary, 12GB Unallocated. After applying those changes, I went into Disk Utility and the HD appears along with the correct partitions. When I try to mount the volumes for partitions 1 and 3, I get a pop-up stating: Error Mounting Volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. When I try to to check the filesystem I get a pop-up stating: Error Checking filesystem on volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. Throughout the time that I'm attempting to troubleshoot the problem, the external drive light is on and blinking. With my frustration hitting a boiling point, I try to shut down the drive and remove it so that I can plug in a different external HD that works PERFECTLY. However, when I try to shut down and safely remove the drive, I get a pop-up stating: Error Detaching Drive An error occurred while performing an operation on "80GB Hard Disk" (HTS548080m9AT00): The daemon is being inhibited. Can anyone tell me what I'm doing wrong? I'm a newbie and not that skilled with terminal commands, so please dumb it down for me if you request specific command output.

  • Custom daemon script: works, but does not run at boot / startup

    - by pearjoint
    this is Ubuntu 10.10 Maverick. I have the following shell script in init.d that I want to run as a "daemon" (background service with start/stop/restart really) at system startup. There is a symlink in rc3.d. I tried 4 and 5 too. (Ideally this would initialize before graphical login happens and before a user logs in.) IMPORTANT: the script works 100% as expected and required when testing this with service MetaLeapDaemon start and service MetaLeapDaemon stop. (This shell script calls a Python program which makes sure the appropriate .pid files are both created at startup and deleted at exit.) So generally it works fine but now my only issue is why it will not be run at any of the run-levels I tried. I know for sure it isn't run because the log file it normally creates does not get created. As you can see (by the lack of any uid:gid args in the start-stop-daemon commands) this would currently run only under root, is this forbidden in a default setup? Here's the script, pretty much your run-off-the-mill daemon script really: #! /bin/sh DAEMON=/opt/metaleap/_core/daemon/MetaLeapDaemon.py NAME=MetaLeapDaemon DESC="MetaLeapDaemon" test -f $DAEMON || exit 0 set -e case "$1" in start) start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; stop) start-stop-daemon --stop --pidfile /var/run/$NAME.pid ;; restart) start-stop-daemon --stop --pidfile /var/run/$NAME.pid sleep 1 start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart}" >&2 exit 1 ;; esac exit 0

  • Impossible to enable bluetooth under Ubuntu

    - by PCh
    I just installed Ubuntu 12.04 (dual boot, kept Windows just in case) on my new Acer Aspire One 756-877. As soon as I installed it I also installed the Broadcom driver, since wifi wasn't working, and that solved it right away. But when I tried Bluetooth, I had a problem that I see is quite recurring: -The hardware is on (and working fine under Windows) -The icon shows up on the menu, giving me the options of turning Bluetooth on or off, and then just "Bluetooth preferences". -I can apparently turn it on that way, which only lights up the icon but makes no difference at all (and doesn't give any other options in the Bluetooth menu) -When I open "Bluetooth preferences" (whether Bluetooth is apparently on or off, it makes no difference), it says it's disabled and will not let me slide the button to enable it. I've rebooted, but nothing happens. -The material is Broadcom and the port (if it's relevant at all) is Port_#0001.Hub_#0003 I tried the following commands suggested in other similar questions, with no result at all: sudo dmesg | grep blue and sudo service bluetooth start and sudo /etc/init.d/bluetooth start Any other clues on what I can do? Thanks for your time!

  • Terminal closing itself after 14.04 upgrade

    - by David
    All was fine in 12.04, in this case I'm using virtualbox in Windows. Last days the warning message about my Ubuntu version no longer being supported was coming up pretty often, so, yesterday I finally decided to upgrade. The upgrading process ran ok, no errors, no warnings. After rebooting the errors started to happen. Just after booting up there were some errors about video, gnome, and video textures (sorry I didn't care in that moment so I don't remember well). Luckly that went away after installing VirtualBox additions. But the big problem here is that I can't use the terminal. It opens Ok when pressing control+alt+t, but most of the commands cause instant closing. For example, df, ls, mv, cd... usually work, although it has closed few times. But 'find' causes instant close. 'apt-get' update kills it too, just after it gets the package list from the sources, when it starts processing them. I've tried xterm, everything works and I have none of that problems. I have tried reinstalling konsole, bash-static, bash-completion, but nothing worked. I have no idea what to do as there is no error message to search for the cause. It seems something related to bash, but that's all I know.

  • Getting "Unable to find a medium containing a live file system" when installing 10.10

    - by Krastin Konstantinov
    I got this error while trying to install ubuntu 10.10 from a bootable USB stick on to Sony Vaio P series laptop. The disk boots into the language and installation type screen. After that it goes through the splash and pulls up this error: BusyBox v1.13.3 (Ubuntu 1:1.13.3-ubuntu11) built in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Unable to find a medium containing a live file system After getting this error the installation fails to start. I have used the same USB stick on some other laptops and the installation started as usual. Any help will be appreciated. My installation is i386 and my machine is Vaio P VGN-P610. I've tried every possible thing: Bios: [enable boot external] Boot order: [external] [hard drive] [network boot] Tried 2 different USB drives Tried 2 different external CD drives Tried 6 different downloads of both the desktop and netbook remix.

  • Delaying a Foreach loop half a second

    - by Sigh-AniDe
    I have created a game that has a ghost that mimics the movement of the player after 10 seconds. The movements are stored in a list and i use a foreach loop to go through the commands. The ghost mimics the movements but it does the movements way too fast, in split second from spawn time it catches up to my current movement. How do i slow down the foreach so that it only does a command every half a second? I don't know how else to do it. Please help this is what i tried : The foreach runs inside the update method DateTime dt = DateTime.Now; foreach ( string commandDirection in ghostMovements ) { int mapX = ( int )( ghostPostition.X / scalingFactor ); int mapY = ( int )( ghostPostition.Y / scalingFactor ); // If the dt is the same as current time if ( dt == DateTime.Now ) { if ( commandDirection == "left" ) { switch ( ghostDirection ) { case ghostFacingUp: angle = 1.6f; ghostDirection = ghostFacingRight; Program.form.direction = ""; dt.AddMilliseconds( 500 );// add half a second to dt break; case ghostFacingRight: angle = 3.15f; ghostDirection = ghostFacingDown; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; case ghostFacingDown: angle = -1.6f; ghostDirection = ghostFacingLeft; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; case ghostFacingLeft: angle = 0.0f; ghostDirection = ghostFacingUp; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; } } } }

  • Failed to fetch *.deb Size mismatch, then packages with unmet dependencies [solved]

    - by user113907
    I recently bought the wonderfully looking and reviewed Amnesia The Dark Descent and I'm trying to install it. The first time I tried to download it, I had to stop in the middle of the download (may have broken something). The second time I tried to download, at the end of the download it gave me the following error: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/amnesia/ubuntu/pool/main/a/amnesia/amnesia_1.2.1-0ubuntu2_i386.deb Size mismatch Now, whenever I try to download it, it gives me this error: The following packages have unmet dependencies: amnesia: Depends: libalut0 (>= 1.0.1) but it is not going to be installed Depends: libc6 (>= 2.4) but 2.15-0ubuntu10.3 is to be installed Depends: libfontconfig1 (>= 2.8.0) but 2.8.0-3ubuntu9.1 is to be installed Depends: libfreetype6 (>= 2.2.1) but 2.4.8-1ubuntu2 is to be installed Depends: libgcc1 (>= 1:4.1.1) but 1:4.6.3-1ubuntu5 is to be installed Depends: libopenal1 (>= 1:1.13) but 1:1.13-4ubuntu3 is to be installed Depends: libsdl1.2debian (>= 1.2.10-1) but 1.2.14-6.4ubuntu3 is to be installed Depends: libstdc++6 (>= 4.1.1) but 4.6.3-1ubuntu5 is to be installed Depends: libxft2 (> 2.1.1) but 2.2.0-3ubuntu2 is to be installed Depends: zlib1g (>= 1:1.1.4) but 1:1.2.3.4.dfsg-3ubuntu4 is to be installed I already searched the net and ran a few command line commands. Ex: sudo dpkg --configure -a sudo apt-get install -f Or configure the software packages to download from Main instead of the local UK server. But I'm really not figuring out a solution. I have a fresh install of the latest LTS (12.04). The only non-standard thing so far is that I installed gnome-shell (?) because I really can't stand Unity. Help would be much appreciated. I am currently more than entertained enough with World of Goo and Command & Conquer, but I will want to play Amnesia in the close future.

  • How to install .deb file from within preinst script

    - by Ashwin D
    I have my own application packaged using dpkg. The application depends on several deb files which I'm trying to install from within the preinst script of my application. The preinst script checks if a dependent deb file is installed, if not it goes to installt it using the dpkg -i command. This is repeated for all the dependent deb files needed by the main application. When I try to install the main application using dpkg -i, the commands returns failure when trying to execute the preinst script. Below is that error message. dpkg: error: dpkg status database is locked by another process I deleted /var/lib/dpkg/lock file and retried to install the application. But to no avail. If I run the preinst script separately like any other shell script, it runs without any issue. All the deb files will be installed properly. So, the issue is only when this preinst script is being run automatically by the dpkg -i command. I'm lost trying to determine the root cause. If anyone can shed some light on what the real issue might be, their help will be greatly appreciated. Thank you. Ashwin

  • How should I load level data in java?

    - by Matthew G.
    I'm setting up my engine for a certain action/arcade game to have a set of commands that would look something like this. Set landscape to grass Create rocks at ... Create player at X, Y Set goal to "Get to point X Y" Spawn enemy at X, Y I'd then have each object knowing what it has to do, and acting on its own. I've been thinking about how to store this data. External data files could be parsed by a level class, and certain objects can be spawned through that. I could also create a base level class and extend it for each level, but that'd create a large amount of classes. Another idea is to have one level parser class, but have a case for each level. This would be extremely silly and bulky, but I mention it because I found that I did this at 2 AM last night. I'm finally getting why I have to plan out my inheritances, though. RIP project. I might be completely missing another option.

  • Architecture of an action multiplayer game from scratch

    - by lcf
    Not sure whether it's a good place to ask (do point me to a better one if it's not), but since what we're developing is a game - here it goes. So this is a "real-time" action multiplayer game. I have familiarized myself with concepts like lag compensation, view interpolation, input prediction and pretty much everything that I need for this. I have also prepared a set of prototypes to confirm that I understood everything correctly. My question is about the situation when game engine must be rewind to the past to find out whether there was a "hit" (sometimes it may involve the whole 'recomputation' of the world from that moment in the past up to the present moment. I already have a piece of code that does it, but it's not as neat as I need it to be. The domain logic of the app (the physics of the game) must be separated from the presentation (render) and infrastructure tools (e.g. the remote server interaction specifics). How do I organize all this? :) Is there any worthy implementation with open sources I can take a look at? What I'm thinking is something like this: -> Render / User Input -> Game Engine (this is the so called service layer) -> Processing User Commands & Remote Server -> Domain (Physics) How would you add into this scheme the concept of "ticks" or "interactions" with the possibility to rewind and recalculate "the game"? Remember, I cannot change the Domain/Physics but only the Game Engine. Should I store an array of "World's States"? Should they be just some representations of the world, optimized for this purpose somehow (how?) or should they be actual instances of the world (i.e. including behavior and all that). Has anybody had similar experience? (never worked on a game before if that matters)

  • How can I find which "command" corresponds to opening a gnome-panel menu, for use in a keyboard shortcut?

    - by Ryan Jendoubi
    There are many questions and answers here and around the web on setting basic keyboard shortcuts in GNOME. Most of them are either for launching applications, or Compiz settings, or for changing defaults for other things for which Ubuntu provides defaults shortcuts. What I want to know though is how to refer to a gnome-panel menu item in a custom keyboard shortcut. I'm using Ubuntu 11.10 with GNOME Classic, and the old GNOME 2 / Ubuntu 10.04 keyboard shortcuts for the main menus (Alt-F1) and the "Me Menu" (Super+S) don't seem to work. So my question is two-fold. Primarily I'd like to know how to set those shortcuts. But a second-order question is how I could have found this out myself: is there some program I can use to see what signals or commands are fired off when I click on various things, in this case gnome-panel menu items? I'm interested in the broader question because I've sometimes wanted to set shortcuts for specific menus or menu items in GNOME 2, so a way to find out what command I need there would be useful. Give a man a rod, as they say :-) I've had a look at a good lot of keyboard shortcut and menu related items here to no avail. One somewhat relevant question is this one, but it's just a "how do I do it" question, and applies to Unity, not GNOME, although it would be great if whatever investigatory method answers this question might also apply under different desktops, like Unity. The answer to this question is essentially how I was doing it in 10.04 / GNOME 2, although the questioner's query isn't exactly addressed - how to get directly to "Broadcast" with a key combination. Again, it would be great if an answer delving into how such menus work and how they interact with the rest of the system would be applicable to pinpoint menu items.

  • Very large log files, what should I do?

    - by Masroor
    (This question deals with a similar issue, but it talks about a rotated log file.) Today I got a system message regarding very low /var space. As usual I executed the commands in the line of sudo apt-get clean which improved the scenario only slightly. Then I deleted the rotated log files which again provided very little improvement. Upon examination I find that some log files in the /var/log has grown up to be very huge ones. To be specific, ls -lSh /var/log gives, total 28G -rw-r----- 1 syslog adm 14G Aug 23 21:56 kern.log -rw-r----- 1 syslog adm 14G Aug 23 21:56 syslog -rw-rw-r-- 1 root utmp 390K Aug 23 21:47 wtmp -rw-r--r-- 1 root root 287K Aug 23 21:42 dpkg.log -rw-rw-r-- 1 root utmp 287K Aug 23 20:43 lastlog As we can see, the first two are the offending ones. I am mildly surprised why such large files have not been rotated. So, what should I do? Simply delete these files and then reboot? Or go for some more prudent steps? I am using Ubuntu 14.04.

  • ALPS touchpad stops working after reboot

    - by user58289
    I recently upgraded to 12.04 LTS. My Compaq Presario CQ-40 324la touchpad worked after first restarting after installation. But after restarting a second time, the touchpad is completely disabled, without having changed anything in the system. I've tried solutions but haven't had good results. The applications I've installed (fro "solutions" are: Pointing Devices Synaptiks Dconf-Tools I've also tried updating GRUB, adding this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") I tried these commands in a terminal. Neither has worked. sudo modprobe -r psmouse sudo modprobe psmouse proto=imps El Touchpad ALPS se desactiva al reiniciar Recién he actualizado a Ubuntu 12.04LTS y a mi parecer ha mejorado mucho con respecto a 11.10... Pero ese no es mi punto ahora. El Touchpad funcionó correctamente luego del primer reinicio después de la instalación. Pero luego de volver a reiniciar, el Touchpad queda totalmente deshabilitado sin haber hecho cambio alguno en el sistema. He probado las soluciones en su mayoría y no he tenido buenos resultados. Las aplicaciones que he instalado (de las "soluciones") son: -Dispositivos apuntadores. -Synaptiks -DConf-Tools Y he intentado también actualizando el grub (añadiéndole una linea así: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux") Intenté en la terminal con el comando: sudo modprobe -r psmouse sudo modprobe psmouse proto=imps Ninguno me ha resultado bien. La laptop es Compaq Presario CQ-40 324la

  • How do I disable touchpad tap to click?

    - by AWE
    You've heard this a million times but the "tap to click" is a pain in the behind and I want to disable it. There is no touchpad in gpointing-device-settings and neither in mouse and touchpad in system settings. I've tried some commands in terminal but it's all crap. Dconf-editor doesn't react. How about solving this once and for all? xinput list: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PS/2 Generic Mouse id=13 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ?

  • A terminal emulator for ex-Windows users

    - by Dan
    There are several things I would like to be better in Ubuntu Terminal Emulator. coloring, like in the source code Copy and paste keyboard shortcuts that I used all the time in Windows: Ctrl-C and Ctrl-V (Most of people here in Ubuntu use Ctrl+C and Ctrl+V keyboard shortcuts to copy and paste everywhere except the terminal! I think it's annoying for newcomers, and I don't worry about historical reasons) A feature to save all the output to log file UPDATE: Can the terminal be a powerful feature-full user-friendly tool like a modern IDE? The Linux user can spend 30% of time in the terminal. Programmers no longer code in a notepad. Can I see the history pane? Suggestions? Directory pane? Commands list? Search for words in an output? Contextual behavior? "Search in Google" for a mouse right-click. Tips and tricks learning? Time is money! Please, people, give me a link to the 21st - century terminal.

  • Ubuntu 12.10 with kernel 3.5.0-18

    - by Chaitanya
    I had ubuntu 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I cant take screenshot of that. It looks something like, [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; something like this. Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that wierd error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help..... Thanks, Chaitanya.

  • Can I install new version of Ubuntu in spair RAIDed partition with unetbootin

    - by artfulrobot
    I have Ubuntu 11.04 running on my home desktop which has 2 hard drives mirrored by RAID. The drives are partitioned with a big data partition, a swap partition and a couple of 20Gb partitions for OSes, one is 11.04 which is in use, and the other is kept spare for installing a later version. Which is what I'd like to do now. The idea of a 2nd partition for new OS is that I can try it, and if it's problematic, I can boot back into the original one - the machine is shared with others, so I need it to stay available! I have had horrible problems with software RAID after using a Live USB stick - basically it messes up the internal numbering of the RAID drives or something, anyway, the result is you can't boot after using it :-( and have to spend ages re-assembling the arrays, trying to remember grub commands etc etc. Quite a shocker when you consider booting from a Live USB is supposed not to affect the existing system. As I'm installing in a RAIDed disc, I would typically use the Alternative install (sad to hear that this is going to be dropped in future). However, I think I might be able to use unetbootin to trick the system into working on top of the existing system that understands RAID, with the normal ISO? If unetbootin loads from drives that are already understood to be RAIDED, then presumably it will only see md0... instead of sda, sdb... and as long as I don't need to repartition (I don't) it should be fine, right? Or is that just plain foolishness? Please tell me before I end up with a dead system (again!)
