  • Quickly and Python Twisted

    - by Aaron
    I am creating a Quickly application that makes use of Python Twisted. When the user launches a window, I want to start the Twisted server I wrote. However, when I do this, it freezes the GUI, because the reactor.run method is constantly running after it is started. I need a way to start the Twisted reactor in its own thread, so that the GUI will continue to operate while the reactor is running. I have read about using Twisted with pyGTK in the Twisted documentation, but I am not sure how I would accomplish this with a Quickly application. What is the best way to start my Twisted server when a window opens without freezing the GUI? Update: My if __name__ == '__main__' statement at the end of my dialog file is: print 'Preparing GLib' GLib.idle_add(before_running) print 'Staring Reactor' from twisted.internet import reactor reactor.run()` I have imported and installed twisted.gtk3reactor earlier on in the file. The before_running method contains dialog = ClientDialog() and dialog.show, as well as the rest of the code I want to run when the dialog opens.

  • I don't have the password to update Ubuntu

    - by Steve
    I have bought a laptop with Ubuntu 12.04, which runs fine but wants to update. I don't have the password and it won't let me update anything. I have downloaded 12.04 in order to re-install it and it tells me it isn't suitable for my processor. The machine is a Dell latitude D505. I tried downloading the i386 version and on booting with the disc, I get: This kernel requires features not present on CPU. pae. Unable to boot. All I'm trying to do is to let software updater do it's stuff but as it asks for a password, I can't proceed. I've tried changing password in root shell but that doesn't work. Any ideas? Nothing seems to be working with this problem, so maybe I'll just wait for the next official release and try again.

  • 11.10 had sound, 12.04 doesnt. Acer Aspire One D257

    - by Jeff Welling
    I'm wondering if anyone else has had this same problem, because if so it might be worth while for me to file a bug, but it might also be chaos monkey so I wanted to check first. I have an Acer Aspire One D257 and the sound worked in 11.10 by default, but after doing a fresh install of 12.04 there is no sound. There used to be a speaker icon on the menu bar but now there isn't, and volume up and volume down hotkeys now do nothing, which leads me to believe it isn't detecting the sound card properly anymore. Googling for sound problems on an Acer Aspire One D257 on 12.04 isn't showing any helpful results, so I'm wondering if it's just me. Does anyone have an AAO D257 on 12.04 with the sound working, and if so did you have to do anything special to make it work?

  • issue with older laptops

    - by Adam
    I recently reimaged my Lenovo t400 with Ubuntu. However, after wiping two other systems (Compaq Presario 2100 and Dell Latitude D600) both hUbuntu 11.10 and Ubuntu 12.04 fail to load on boot. I am concerned that there is some type of issue using Ubuntu on these older systems as every part of the process has been repeated/attempted several times in the same manner as practiced in the successful load of the newer Lenovo t400. I now have two laptops without an operating system as the discs/thumb drives that were formatted to load on these devices do not seem to work. I would appreciate any assistance that you may be able to provide. Regards, -Adam

  • How to Boot from iRAM Solid State Drive on Ubuntu

    - by quickshiftin
    I've got an iRAM solid state drive. I'd like to use this to store a linux root filesystem; the trouble is the device is not recognized as a hard drive to the BIOS. It only shows up if a live CD environment is loaded and the scsi drivers are available (may be other drivers needed as well). I've heard of Boot to Ram and wonder if some variation of that could work here and I could run a linux install off the iRAM??

  • USB mouse / keyboard not working after suspend

    - by Frode
    After upgrade from 12.04 to 12.10, the USB mouse/keyboard is not working when the laptop wake up from suspend. I need to remove and insert the USB dongle to get keyboard/mouse working again. This was not a problem before the upgrade. 6 months ago I had the same problem when upgrading from 11.10 to 12.04. At that time I solved it by doing a clean install of 12.04. Updated: Issue resolved after installing ppa:xubuntu-dev/xfce-4.12

  • How to tune touchpad for smaller area?

    - by M.L.
    I just purchased the Asus Zenbook UX31A and I require some advice regarding tuning the touchpad. Basically my problem is that the mouse buttons are withing the touch area and I would like it to be disabled. Such that only part of the touch area is recognized. I have attached an image to clarify the idea. Basically only the red area in the image should be recognized. I have two reasons for this request. Firstly, I like to hold my thumb on the mouse button instead of holding it in the air. This is problematic, because touchpad thinks that I'm trying some kind of two finger gesture all the time and cursor stops moving. Clicking is also problematic since every finger movement -- regardless of how insignificant it might be -- on the "button" will move the cursor. I have been playing with some synclient settings like AreaBottomEdge etc. They have some effect but then I cannot highlight text or right button stops working. How could I solve this?

  • External hard drive issue

    - by Blind Fish
    I am running Ubuntu 12.04 and I have a 500GB external hard drive, formatted in ext4, which I have used for about a year to store batches of data that I am sifting through. About once a week I move a chunk of data from the external drive to my internal drive for processing. As I do that I delete the data from the external drive and empty the trash, thereby clearing up space on the external and also preventing myself from grabbing stuff that I've already sorted through. The vast majority of this is text files, but there are a few .jpegs and .mp4s thrown in, if that matters. Anyway, this has been working without a hitch for nearly a year. So today I plug in the drive and I have an odd issue. I was able to move folders from the external over to my internal drive with no problem, but when I tried to delete those files I was unable to do so. I kept getting the "unable to send file to trash, do you wish to delete permanently?" message. I clicked yes / delete all, but no files were actually deleted. It just sat there. Even worse, while the system was trying in vain to delete those files I was unable to move more files over. In short, I was stuck. I canceled the operation, unmounted and remounted the drive, and then I had an even bigger problem. I have a spreadsheet of all the different folders on there ( exactly 818 ) and yet when I opened the drive in Nautilus, it was only finding 512 folders. So I had 306 missing folders, but my free space was unchanged. Immediately I think that the drive may be corrupted. I went into Disk Utility and ran the check disk option. It said that the drive was NOT clean, but offered no remedy or option to repair. I went back into the drive in Nautilus and once again attempted to delete the files I had already moved. Same issue. I clicked on Details and it said that it was unable to create a trashing file I/O error. I've looked, and it's not a permissions issue. The drive and all folders that are in it all belong to me, and they are all read / write. I've started running badblocks on the drive, but it looks like that is going to take several hours to complete. Any ideas?

  • IRQ Conflicts Causing Video Card and Boot Problems?

    - by sanpatricio
    tl;dr - I have 4 devices sharing 1 IRQ. Is this bad and how do I tell the BIOS to stop it? Background: I have an old Dell GX280 dual Pentium 4 that I (semi) resurrected last weekend with an installation of Ubuntu 12.04. Everything was going fine the first several hours until a problem that plagued me when WinXP was on that machine happened -- it froze. Completely froze. None of the myriad of ways I have found here on askubuntu helped me to regain control except a long-press of the power button to shut it off. Clearly, this wasn't a software/WinXP issue. After much googling, I found that hardware conflicts can often cause this sort of total lock-up and with all the odd blocks of yellow and flecks of color showing on my screen (both WinXP and Ubuntu) I figured my old GeForce 7600 was failing and causing me these odd issues. (A good canned-air dusting of the entire interior fixed the color fleck problem) Again, through much googling and numerous answers found on askubuntu, I somehow stumbled my way onto the lshw command. After going through it, line by line, I found that I have four devices sharing IRQ 16: eth0, wlan0, ide0 (DVD-RW), and my video card. In hindsight, I can recall weird instances of my Ethernet connection to another computer not working when I thought it should. I never full troubleshot those issues so it could be a coincidence. The other thing that has been plaguing me since installing Ubuntu (wasn't there during WinXP) has been periodic moments of my monitor getting no signal from Ubuntu during boot. The first couple days, it would disappear after the Dell boot screen and reappear at Ubuntu login. Now, it disappears after the Dell boot screen and doesn't return at all -- I have to hit F12 where I can load a safe mode version of Ubuntu and get more details like dmesg and lsdev. I also ran memtest86 overnight and woke up to zero errors, so failing RAM is out. Where do I go from here?

  • How to install Edubuntu on a system with low memory (256 Mb)?

    - by int_ua
    I'm preparing an old system with 256 Mb RAM to send it to some children. It doesn't have Ethernet controller and there are no Internet access at the destination. I've chosen Edubuntu for obvious reasons and modified it with UCK trying to minimize memory usage just to install, let alone using it yet. But Ubiquity won't start even in openbox (edited /etc/lightdm/lightdm.conf) because there are no space left on /cow right after booting. I've already deleted things like ibus, zeitgeist, update-manager (no network access after all), twisted-core, plymouth logos. I'm thinking about creating a swap partition on HDD, can it be later added to expand this /cow ? Is there a package for the text-mode installation which is used on Alternate CDs? I don't want to re-create Edubuntu from an Alternate CD. This behavior is reproducible in VM limited to 256Mb RAM.

  • Nautilus ignores / misinterprets view size

    - by BlueZero4
    I noticed that a lot of my folders had suddenly switched to higher view sizes than I had specificied. I was assuming that somehow nautilus had suddenly decided to create per-folder entries for said folders with incorrect view sizes. So I found this question: How to reset all per-folder view settings in nautilus? I found the folder specified in the answer (~/.local/share/gvfs-metadata) and found that it was actually important to delete the files INSIDE the folder, because for some reason deleting the folder itself didn't work for some reason. After doing that, I discovered that the odd setting was for the default view settings, not for a handful of files. Nautilus actually handles the per-folder settings like it should, but it ignores the global folder settings. I want Nautilus to, by default, display all non-specified folders as compact view, 50%. My folders are using the compact setting like I want, but they are not down to 50%. At a guess, they are at 100%. Altering the view size of the icon view can set the compact view to 33%, but I'm not sure by what mechanism this functions. I haven't extensively tested the other view sizes because I don't plan on using them much at all. Next I looked up questions like How do I reset nautilus to the default configuration? I'm expecting the problem to be a corrupted config file or something of the sort, so I hunted down directories like ~/.nautilus, ~/.gconf/apps/nautilus, and ~/.gnome2/nautilus. (I don't have a ~/.nautilus directory, so I'm assuming that's only for older versions.) I attempted to remove the contents of each, but I can't seem to force Nautilus back to default configuration settings. Actually viewing Nautilus's preferences in GConf made the settings look like they were what I wanted them to be, which is odd. I'd like to force Nautilus to default settings, basically. Though if something else will fix it, I'll take it too. I'm not interested in doing a full uninstall, reinstall of Nautilus if I don't have to. ==EDIT1== Turns out that Nautilus just writes the settings in GConf for the heck of it. Nautilus only really uses the settings that it stores in DConf. I did gsettings reset-recursively org.gnome.nautilus, which actually did reset Nautilus to default, but it still doesn't like my view size settings.

  • On-the-fly file search in gnome 3?

    - by jan groth
    I recently switched to Gnome 3 (on Onereic 11.10). I was a big fan of gnome-do (on Gnome 2), where I heavily used the "files and folders"-plugin. This allows to configure a list of files and folder to be searched on-the-fly while typing. E.g. starting to type "timesheet" opens "timesheet_2011.ods" from my dropbox account... I can't find anything like this in Gnome 3. I know that there is a list of "recent items", and also the name of bookmarked folders in nautilus is searched, but that's not (exactly) what I'm looking for... So, what I want is this: tell Gnome 3 where my files are (certainly not only in my home folder) have them searched on the fly while I'm typing I think Unity offers something like this - but hey, I'm using Gnome 3 ;-) Anything I missed?

  • One monitor getting spilled over into other monitor: how to do a 100% reset of gnome graphics configuration

    - by Paul Nathan
    I had to kill a VMWare process and afterwards, my monitor's configuration is buggy. I have 2 monitors in a side-by-side configuration. My right-hand monitor is the secondary monitor. Upon its right-hand side there are about 50 pixels showing from the left side of the lefthand monitor (ie, as if it was wrapped around). Further, my mouse clicks are registering as about 50 pixels sideways from where they should be. It's as if those 50 pixels between monitors got gobbled. What have I done? I've reset the screen configuration in multiple ways, using xrandr, multiple monitors app, etc. This persists in different side-by-side configurations, and also persists with another user. It does not occur with XFCE. Resetting the Window manager with the Compiz reset WM app does not fix this. I've concluded the burn-to-the-ground approach is likely the best, and would like to do a 100% reset of my graphics settings. It's an Intel integrated chipset. Removing ~/.config/monitors.xml did not work. Also, interestingly, the mouse can mouse-over the 50 errant pixels on the rhs of the right-hand monitor. I hypothesize that it's a compositing problem occurring at the layer where the background, selection, and clicks are caught. Also, inverting the right-hand monitor removes the issue, but renders the screen unusable. Even more datapoints: This happens in KDE as well Sometimes logging into Gnome and running xrandr --output DVI1 --auto resets it, but the issue immediately reappears when I press alt-tab. With Compiz Application Switch turned on, the workspace is 'pushed back' a bit, and the slice on the RHS follows it as well. I'm wondering if it's a flaw in the compiz workspace compositing configuration. I suspect the error was in the compositing configuration. I installed 11.10.

  • How can I run Ubuntu if it's not on my main drive?

    - by Stephen
    I have a 120GB SSD and a 750GB HDD in my computer. My SSD has Windows 7 installed and my HDD has Windows 8 installed. When I boot my computer normally, I boot it to my SSD. I went through the installation process, putting Ubuntu on a separate partition on my HDD. When I restarted my computer, it didn't give me an option to boot to Ubuntu. If it helps, I believe I used ext4 and only set it to '/'. If I want to make Ubuntu bootable from my computer, how would I go about doing that?

    I have an old PC that is now my new Ubuntu machine. Currently I was working on sharing a drive so that backups and streaming could take place. I have it set up perfectly on my windows 7 laptop (able to read and write to it). For some reason however my wife's windows 8 laptop is not showing up on the Ubuntu and vice versa. I turned on network discovery on the win8 machine, but that didn't help. Thanks in advance edit- I have my win7 and win8 in the same homegroup and both can see each other in the network. Also the workgroup is the same.

  • Can I use Ubuntu to write a Windows 7 ISO to USB?

    - by Salim Fadhley
    I need to create a Windows installation USB drive from an ISO file. I used UNetbootin which seems to be the only tool that can write non-Linux images. The USB disk boots (sort of), but it gets stuck at the very first stage. A UNetbootin splash screen appears that keeps counting down from 10 to 0, and then restarts. The screen looks like this: Is there a way to make Windows boot from a USB image created on Linux?

  • Acer Aspire microphone issue

    - by Dr_Bunsen
    I have got an Acer Aspire 7750G: More info It has been running Ubuntu since I bought the laptop (12.10 as of now), but a few updates ago, I lost my microphone. It doesn't recognise the internal mic or the mic jack (although alsa seems to recognise it). I have been looking around, and I fixed it, but this was only temporary, after a reboot my mic was gone again. I haven't been able to find the fix, so I wanted to know whatever you guys know what I have to do to fix this. Thanks in advance.

  • How to remove non-working session entries in LightDM?

    - by Lexalt
    I recently added Cairo Dock to my GNOME Shell in 11.10. Cairo Dock is GREAT, but I'm left with one little problem that I'd like to fix: after installing Cairo Dock, LightDM includes two extraneous entries to non-working desktops. (The entries to working desktops remain unaffected, so I guess I could just ignore the extraneous entries, but...) So I'd like to remove/edit the extraneous entries in LightDM. I've looked and looked for discussions on how to do so, but haven't had much luck. Any suggestions on how to go about editing the login menu in 11.10?

  • Upgrade to 12.04, nothing in dash, no date&time

    - by Nicolas
    I've upgraded from ubuntu netbook remix something to 12.04 lts, and I've got two issues. (Got an Asus eeePc 32bits, Intel 945GME x86/MMX/SSE2 and Intel Atom CPU N270 @ 1.6Ghz x2) Nothing in the dash. Only the "home" tab, other tabs are missing. No search result whatsoever. Missing elements in the system panel, privacy and date&time. No date&time on the right corner either. I've tried to reset unity with the terminal but the process was a whole mess full of errors. It did show date&time in the system panel (not on the top-right corner) while the process was going on in the terminal. But then it was such a mess (no more icons on the right corner amongst other things), and the process wouldn't complete: so I had to reboot the computer and get unity as before, still no date&time and privacy. Thanks for any help. nic
