• Google Chrome on Ubuntu 12.04 not rendering webpages correctly

  - by sumit_gt

  I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem? PS: here's the output of lshw -c video: *-display description: VGA compatible controller product: Madison [Radeon HD 5000M Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=fglrx_pci latency=0 resources: irq:46 memory:e0000000-efffffff memory:f0020000-f003ffff ioport:d000(size=256) memory:f0000000-f001ffff Here's the output of lspci -nn: output of lspci -nn

• Map Ctrl and Alt to mouse thumb buttons

  - by murphyslaw

  I'm running Ubuntu 12.04 and have a multi-button Microsoft mouse. I would like to map the CTRL and ALT modifier keys to the left and right thumb buttons of my mouse, respectively, so I can ctrl-click and alt-click without touching the keyboard. My thumb buttons are buttons 8 and 9. I tried the solution in this question: How do I configure a mouse thumb button? which explained how to map a double click to a thumb button - this worked for the double-click but I couldn't figure out how to modify the solution for CTRL and ALT I also tried this: How to map Ctrl/Shift to thumb buttons of Mouse? which used xdotools and xbindkeys. I modified the script to this: ~/.xbindkeysrc: "xdotool keydown alt" b:9 "xdotool keyup alt" release + alt + b:9 "xdotool keydown ctrl" b:8 "xdotool keyup ctrl" release + control + b:8 Which ALMOST works. It simulates a CTRL-key press when I click the left thumb button, but I can't actually hold the button and click at the same time - holding the thumb button seems to prevent it from listening to other input until it is released. Does anyone know how I can make my mouse thumb button actually work as a modifier key, so I can use thumb_button+click instead of CTRL-click?

• VNC Server not responsive after a few days

  - by assylias

  I am new to Ubuntu (11.10) - I installed Ubuntu on a box which has no screen and no keyboard. I connect to that box via tightvncserver. The box is mostly used as a file and media server (i.e. samba + XBMC). So far so good. I can connect via VNC to the box and take control of it. But after a few days, when trying to connect via VNC, I don't get a response. The media server is still on, ping is fine, but VNC is down. The only solution I have found is to plug a screen and keyboard and reboot. I am not sure how to diagnose the problem (maybe some log files?) or if this is just a configuration issue. Any help appreciated.

• Graphics card support

  - by Daryl

  Brand new user to Ubuntu and Linux. Quick question that I think already know the answer to: Does Ubuntu 11.10 have an updated driver for my graphics card? I was planning on being able to s-video out and watch videos on my tv like I could when I had Vista installed. daryl@daryl-Aspire-3050:~$ lspci -nn | grep VGA 01:05.0 VGA compatible controller [0300]: ATI Technologies Inc RS482 [Radeon Xpress 200M] [1002:5975] ATI Radeon Xpress 1100 is the actual card. As it is, Ubuntu is not recognizing when I plug an s-video cable into my laptop. I've narrowed it down to using what I think is a generic driver because all of the s-video enable commands I found and tried have failed.

• Restricting access to sites

  - by Paul

  I'm having some problems configuring my local proxy server so that it would restrict access to certain websites. The proxy server I'm using is Squid; I edited its configuration file found in /etc/squid/squid.conf to include the following: acl wikipedia dstdomain .wikipedia.org http_access deny wikipedia I tried to redirect elinks to use Squid. According to Squid's config file, it listens to port 3128, so in /etc/elinks/elinks.conf I added the following: set protocol.http.proxy.host = "localhost:3128" I also restarted Squid with sudo /etc/init.d/squid restart, but I can still access the banned websites using Elinks. What did I do wrong?

• Wireless connection keeps losing connection

  - by Santiago

  I'm having this annoying problem with my Ubuntu 12.04.1, upgraded from 10.04. The thing is that my wireless connection keeps going out of connection every 15-20 minutes, and sometimes I have to reboot my laptop. I've started having this problem about 1 month ago, but back in my 10.04 I had the same problem. If anyone has any idea it would be great. Also any info you need about the laptop, please tell me the commands I need to run to give it to you. Thanks and hope you help me.

• I installed Ubuntu alongside Windows but I can't see it in Windows' boot menu

  - by André Hallé

  I have a second machine where Ubuntu 12.04 LTS and Debian Squeeze are installed on the same HD and when I boot, I have this grub menu where I can choose which partition I will used. It works perfectly! But in my Windows environment that's another story. Now after making almost everything that I know, to make it work along Windows 7, there is no entry in the boot menu of Windows (I know, Ubuntu use grub but anyway there is surely a way to fix it, access it?). Why there is no Ubuntu entry? Why the installation gave me no error while I have this strange situation of having a "ghost OS" called Ubuntu installed somewhere in my second HD in a partition made especially for it and not being able to access it, starting it, having it working? Am I wrong? If I am, what's the problem? If I'm not, what's the need of Wubi?

• System Settings and Software Center does not pull up after fresh install 11.10 amd64

  - by hydroparadise

  I've had a few install rounds with ubuntu ever since 8.04 and has worked flawlessly every time. However, for some reason, when I try to click either System Settings or Software Center, the icon pulses as if it were working to come up but never does. The same goes for System Settings. I would expect that a password dialog would appear, but nothing shows. Is there bug with 11.10 that didn't exist with 11.04?

• Broke my sudoers password, how do I reset it without using sudo?

  - by Eric Dand

  I thought it would be a good idea to finally take the password off my little netbook since it has never actually been of any use, and has mostly just slowed down . But when I went to change my password, there wasn't even an option to make it blank, and any attempt to make it a few easy characters was met with "Password too weak". So I did what any good geek would do and popped open the terminal, read the manual entry for passwd and quickly used the -d option to remove the password from my account. It all went well for a couple days (I even managed to also make my keychain password blank) until I tried to update the thing. My sudoers password is not blank, and it's not my old password. I have no idea what it is. How do I reset it (or even better, make it blank) without the use of the sudo command?

• VirtualBox install

  - by Chris

  I am using Win 7 Ultimate. I have the current version of Virtualbox. I downloaded Ubuntu 12.10 from the Ubuntu website and the install as disc image. Ubuntu probably goes thru about 75% of the install and then I get an error message saying that there is a hardware issue and cannot continue. The error message also says it cannot read the disc, etc, etc. I have downloaded 2 different versions of Ubuntu. I had downloaded and re-installed VirtualBox twice. I also tried 12.04 but came into the same issue. I downloaded the "desktop AMD-64" Thank you in advance for your help.

• How can I show Thunderbird Lightning tasks and events in the Gnome Clock applet?

  - by Niriel

  We used to have this functionality with Evolution: clicking on the date-time in the gnome panel would show a list of events/tasks/appointments from the Evolution Calendar. As an interesting side effect, one would receive alarm notifications even when Evolution wasn't running. Now that Thunderbird is the default email client, I'd imagine that there is a similar functionality for Lightning (Thunberbird's calendar). I just can't find it. Maybe it's not ready ?

• Flickering/Flashing screen problem related to keyboard

  - by LeandroCR

  This will seems quite bizarre but that's a huge problem for me, I'm facing it for a long time since Ubuntu 12.04. My Ubuntu/Linux Mint/Debian (Unity/Gnome) always starts flickering after using the computer for a while, I always thought this had something to do with the video board. I have an Vostro 3550 (Radeon 6xxx/Intel Onboard). First I realized that when I was navigating trough an website, when i selected with the mouse a combo, the combo closed it self automatically then the screen starts flickering. The i realized when i was trying to make the login in the terminal (crtl + alt + f1) a strange character appears, like: ^@ repeatedly. When i keep CRTL pressed the system never flickers! I have absolutely no problem using Windows. What can i do? There is no such thing as Keyboard driver on Dell Support. I would love to use Ubuntu only, but this is very annoying. Problem happens on Ubuntu 12.04, .10 and 13.04 Linux Mint 15 (Cinnamon) Debian Live with Gnome

• How to clear unshown OSD notifications

  - by Avatar Parto

  I am a webmaster of 2 active websites. Every time I start Thunderbird, it downloads all the new messages from the admin mail addresses of these sites - [email protected], [email protected], [email protected], etc. There are about 20 of them - this includes my personal email accounts. Now, am not always connected to the internet and there arises cases where I need to access already downloaded mails. Thunderbird then tries to connect to the internet, which it can't coz am offline, and then displays about twenty OSD notifications, one after the other, telling me that connection for each email address has failed. That's frustrating and it really eating me up. Am looking for a way, either: 1. To tell Thunderbird NOT to connect to the internet when am offline, or 2. To clear all these notifications after like the first one shows. And if it will help, am using ubuntu 13.04 and Thunderbird 24.0 and I always keep my computer fully updated. Any help is welcome. Thanxs.

• New to emacs -- my key bindings are different from what is described in the tutorials. How to fix this?

  - by MountainX

  I'm using emacs v24 [GNU Emacs 24.0.94.1 (x86_64-pc-linux-gnu, GTK+ Version 3.3.20) of 2012-03-26 on meitnerium, modified by Debian] on Kubuntu 12.04. My basic problem is that emacs is not behaving the same as the tutorials I'm reading. I either need different tutorials or I need to make my emacs work as described in the tutorials. Being new to emacs and KDE, I don't know where to start because of this incongruence. My specific problem is this: When I shift-left-mouse-click, I get a buffer dialog popup. That differs from my understanding of the documenation: shift mouse-1 Draws lines, rectangles or poly-lines, erases, cuts, copies or pastes. I also want to use CUA mode. The CUA mode documents seem to indicate that shift-left-mouse-click produces: rectangle highlighting by dragging the mouse while holding down the shift key. I don't get that result either. In fact, I can't select using any modifier keys together with a drag action. Maybe this is a KDE issue. I don't know.

• WiFi AdHoc Network: Unable to access peer by ip

  - by Pranav

  I've set up a WiFi AdHoc network in Maverick and selected the IPv4 settings as "Shared to other computers". On the client computer, I joined the network with the same SSID and set IPv4 method to Manual and I gave it an IP 10.42.43.2 (As on the first computer, the auto generated IP was 10.42.43.1). From either of the computers, I'm not able to access the other using the IP (in browser). Any idea why? (If I browse to 10.42.43.1 from the first computer, it works) Thanks!

• Share between Ubuntu machines

  - by Anero

  I'm sure it might be a very easy way to do this, but I haven't found how... I have two machines with Ubuntu 10.10 on the same network (just workgroup, no domain involved). On one of them I have shared a folder through Nautilus Folder Sharing. When opening the Network place on the second machine, I cannot see the first one listed, just Windows Network and when going into this folder I can see the Workgroup though when trying to go into it I get an Unable to mount. Failed to retrieve share list from server error. Is it required to do something else when sharing the folder through Nautilus?

• Connection timed out when connecting to a website (ubuntu only)

  - by S.C.

  I've been struggling with these problem for months. It happens randomly and it happens on Ubuntu only (12.04). It's about my hosted company website. Some facts: I can ping it I can traceroute it I can dig it I can make a nslookup But whenever I try to open it in Chrome it won't open. I also tried using polipo but got same connection time out issue. I'm connected through a LAN network and I'm experiencing no problem with any other website. Is there a more accurate debugging technique I'm missing other than pinging/tracerouting, etc.?
