• Wvdial randomly drops 3G connection - How to auto-reconnect?

  - by askvictor

  I'm using a 3G modem for a router running Ubuntu server 10.04. I have the connection established using wvdial, which works successfully, but sometimes the connection drops. I would like it to auto re-connect. I've set the "auto reconnect" in wvdial.conf, but this does not seem to work. Any ideas? Am I missing a config option, or should I try writing a script which polls the network status and resets if ppp0 has gone down?

• How To Log Into The Desktop, Add a Start Menu, and Disable Hot Corners in Windows 8

  - by Chris Hoffman

  If you don’t have a touchscreen computer and spend all your time on the desktop, Windows 8’s new interface can seem intrusive. Microsoft won’t allow you to disable the new interface, but Classic Shell provides the options Microsoft didn’t. In addition to providing a Start button, Classic Shell can take you straight to the desktop when you log in and disable the hot corners that activate the charms and metro app switcher. There are other programs that do this, but Classic Shell is free and open-source. Many of the alternatives, such as Start8 and RetroUI, are commercial apps that cost money. We’ve covered Classic Shell in the past, but it’s come a long way since then. How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?

• Cannot connect to Internet after using Windows XP on dual booted machine

  - by babelproofreader

  I have a dual booted Windows XP and Ubuntu 10.10 box (AMD64) and have an unusual problem in that after connecting to the internet on Windows I cannot connect using Ubuntu. I don't believe it is actually a problem with configuring my Ubuntu connections because when I get up in the morning Ubuntu connects without any problem - this problem only exists (and persists for at least several hours) if I try to connect using Ubuntu immediately after connecting using Windows. I don't know how long the problem actually lasts because I usually just go to bed and then in the morning I can connect without problems. It is not problem with my provider's service as I have a second Ubuntu 10.10 box which I manually connect and works even when the dual booted one (on Ubuntu) won't. It is a particular problem with the dual booted box. A power down reset does not solve the problem.

• How to emulate Fn (function key) keypress in xte

  - by komputes

  xte is part of the xautomation package. After hours of man page reading and looking for documentation or working examples, I still cannot get xte to emulate a Fn-F7 keypress. xte 'keydown Meta_L' 'key F7' 'keyup Meta_L' I've tried Meta_L, Meta_R, Multi_key, key F7, keydown F7 then keyup F7. No combination seems to work. Any idea how I can emulate a combination key press with a Fn key from a command/script?

• A rather long question about installation/uninstall

  - by user2364312

  Ok so here's the deal guys, last week I decided I want to install Ubunutu again because I really missed it. (Last time I had an ubunutu was 7.somehting) I downloaded 12.04 and isntalled it via bootable usb device. Knowing how dual boots works I cleared up some space on my hard disc before hand using the windows 7 built in disc manager. During Ubunutu's installation I thought that by choosing "Install Ubuntu alongside Windows 7" will automatically just use the space I cleared before, but apperentaly it did not since that partition is still 100% free space. On what partition is Ubunutu installed when using that method? And how can I uninstall it to re-install it back on the space I cleared up for it? Thank you very your time reading and helping!

• Problem with gnome-shell-extensions-user-theme

  - by sodiumnitrate

  I'm trying to install themes with gnome tweak, and I need to install gnome-shell-extensions-user-theme because otherwise I cannot see the shell extensions tab. However, I cannot install shell extensions. I have tried to install by adding the PPA with the following: sudo add-apt-repository ppa:webupd8team/gnome3 Then, sudo apt-get update Finally, when I try to install: sudo apt-get install gnome-shell-extensions-user-theme It gives an error: The following packages have unmet dependencies: gnome-shell-extensions-user-theme : Depends: gnome-shell-extensions-common but it is not going to be installed E: Unable to correct problems, you have held broken packages. I am convinced that there is a problem with the package. So I went on and tried to install the extensions from the website: https://extensions.gnome.org/ But even though I use Firefox (15.0), I cannot see the "switch" that is being mentioned to install the extension. Maybe the version of Firefox is too new. Is there any workaround that you know of? (By the way, I use Ubuntu 12.04, freshly downloaded and installed.)

• Install build-essentials in ubuntu 12.04

  - by Mukul Shukla

  After I install a fresh copy of ubuntu and I need to install build-essentials, I have to type: sudo apt-get update and sudo apt-get upgrade before installing build-essentials These two commands take a LOOTTT of time and install many things. Is there a way to install build-essentials without running these two commands, or a way that these two commands don't install all the updates and hence will take less time.

• Windows move to external monitor when closing lid

  - by Martijn

  I'm using Cinnamon (on 12.10) on a laptop (Compaq 6710b business model) with an external monitor. Both screens run at 1680 x 1050, the external monitor is located on the right. During normal operation everything works fine; windows open in whatever monitor my mouse pointer is when they open and I can freely drag them to the other monitor. When I close the lid of my laptop both displays shut down as expected. When I open the lid, however, the lock window opens on the external monitor and any windows that were open on the laptop screen have moved to the external monitor as well. Nothing happens between closing the lid and opening it; no suspend, powerdown, hibernate or anything, monitor stays attached; even mouse is untouched (pointer on laptop screen). Is there any way to fix it so my windows stay on whatever monitor I left them before closing the lid? Alternative solutions are welcome.

• Jupiter seems to break multimonitor setup

  - by Philippe

  If Jupiter is in the startup my multimonitor setup will fail. Instead of two separate desktops the monitors will be mirrored, one over the other with the smaller notebook-desktop in the larger screen: After each new log-in I have to reset the Display settings in the "System Settings..." dialogue to two not mirrored screens, the changes don't seem to be saved. Given the the entry from xsession-errors /usr/lib/jupiter/scripts/resolutions: line 42: /var/jupiter/available_resolutions_LVDS: Permission denied I assumed that it's coming from Jupiter. Infact, if Jupiter is removed as startup application the desktop settings are fine. Any idea how to solve that issue?

• How to start contributing to Unity?

  - by Mad-scientist

  I just forked the source code of Unity. I am new to contributing to the project. Do unity developers use any specific IDE? I am asking this because I am confused about where to start and how exactly do I check a change after I do it? Should I recompile entire natty? If so, then how? I know I am asking a lot of questions, but it would be really helpful if someone could write some kind of beginner friendly introduction to unity development.

• I have permanent connections to Canonical servers, what are they for and how can I turn them off?

  After the recent upgrade to 12, I notice permanent connections to canonical servers.

• Use a Coffee Cup Sleeve as a Temporary Lens Hood

  - by Jason Fitzpatrick

  Whether you left your lens hood at home or you don’t even have one, this quick and dirty hack turns a coffee cup sleeve into a temporary lens hood. Slide the sleeve around the lens, take the photos, toss it in the recycling bin. Except for making a quick cut with pocket knife to adjust the size (if need be) there’s not much else you need to do for this simple sleeve-to-hood hack.

• removed ati proprietary driver, tried to hibernate, destroyed ubuntu installation. help?

  - by Niklas

  I totally ruined my Ubuntu 10.10 Desktop x64 installation today. I've never been able to hibernate or suspend (not with my laptop, server or htpc), not even through this guide. So I read a post here on askubuntu.com that said that the proprietary drivers may be in the way for it to work. Therefore I removed my ATI-drivers, rebooted, then tried to hibernate the system. I got some error about "blk_something_something didn't work, resubmitting1". So I turned off the computer and then tried booting up. I see the ubuntu splash but after that I'm greeted with this screen: The upper dot is the mouse pointer since I can move it with the mouse (I have ubuntu set to login automatically). I don't know how this happened. What can I do to fix this? I'm getting seriously irritated over how buggy ubuntu is, why doesn't even suspend/hibernate work (remember that I have 3 different systems where it fails)? So what is the next step? I want to get into cli mode and reinstall the driver but since I'm relatively new to ubuntu I don't know how to get into a terminal without logging in first. And if I press shift during boot I can't get into grub either and try something from there. Please come with all suggestions you can think of! Thank you very much! edit: Can I use ubuntu on a usb to insert the driver I need - if that is the problem?

• Cannot assign keys to Wacom scroll wheel anymore

  - by UncleZeiv

  Hi all, my Wacom Graphire 4 used to work perfectly well until, I think, Ubuntu 10.4. At that point something changed in the configuration and I couldn't assign a key to the scroll wheel anymore (note: the pad's scroll wheel, not the mouse's), i.e this command: xsetwacom set "Wacom Graphire4 6x8 pad" AbsWDn "key +" returns silently without error but nothing happens. Same goes for AbsWUp, RelWDn, RelWUp. Apparently though the problem is even deeper as pressing the wheel in a xev window doesn't seem to have any effect. Moreover I am thoroughly confused on how the various pieces (kernel driver, xorg driver, evdev, HAL, xinput?) are supposed to work together and if the wacom module that ships with Ubuntu is the one from linuxwacom or not. Any ideas? I don't want to become an X.org hacker just to understand what's going on... it used to work! NOTE: I have already read question 3940, but that's not the same problem.

• Touchpad two finger sensivity problem

  - by sagarchalise

  Having asked about touchpad not only once but twice. I have again come back to same topic :D. Basically I have a working two finger scrolling after adding the following line in /etc/profile after I enabled two finger scrolling in touchpad section of mouse. xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 40 But my touchpad sensitivity quite irritates me as it jumps around sometimes and also behaves scrolling as well as right click on single finger sometimes. Anyone can suggest me any tips to minimize this if not avoid ? Anyone know if I could use pinch zoom(Finally got the right term:)) as my touchpad says it supports such activity as well? Thanks in advance.
