• Unity Desktop Displays strange lines

  - by Alex Holsgrove

  Didn't quite know what title to give this problem, but hopefully the screenshot will explain more. I am running a Samsung R60+ laptop on Ubuntu 13.10 with a Radeon X1250 GPU. After I login and the Unity desktop shows, I can see these strange lines at the top of the screen. I presumed it was perhaps a driver issue and found this article to see if I could resolve the issue: https://help.ubuntu.com/community/RadeonDriver I cannot get on with Unity at all (where are all of the menus gone!) so perhaps reverting back to Gnome may be a solution in my case? I'd welcome any ideas please.

• Getting Black screen after installing 12.04 on new Mac Pro

  - by Matteo

  I installed Ubuntu 12.04 on my new Mac Pro. I had some problems because bootcamp did not allow me to partition the hd without a Windows cd. I inserted a Windows cd and did the partition and then I stopped the installation. I completed the installation of Ubuntu that now works. The problem is that Grub can't start Mac OS. It sees the Mac OS X in the menu but if I try to start it I have a black screen or sometime just the boot manager. Has anyone else experienced this problem?

• Monitor not detected - low resolution only

  - by Jens

  I just installed Ubuntu 11.1 on my desktop pc. It was a clean install, no upgrading. I have a Samsung Syncmaster BX2450 connected to the PC. My problem is that I cannot make Ubuntu recognize my monitor - which is capable of more than 1024. I ran a shut down of lightdm, and ran sudo X -configure, but it gave me a "configuration failed".

• Xubuntu 14.04 black screen after monitor off/on

  - by Sampo Smolander

  I have a HP desktop machine with Ubuntu 14.04, with also Xubuntu and Gnome desktops installed. I mostly use the Xubuntu session. When using the Xubuntu session, when I power off my monitor, and power it back on, the screen stays black and I cannot do any work. With ctrl-alt-f6 I can open another virtual terminal, and then the screen works again, but if I to go back to the desktop session with ctrl-alt-f7, all I have is a black screen. But, if I login to Unity (the Ubuntu default session), or to Gnome, and turn the monitor off and back on, everything works ok. Also, if I log out, and while in the lightdm greeter, turn the monitor off and back on, everything works ok. What could be the cause for this, and how to fix this?

• Wifi function key not working on HP laptop

  - by lopsided98

  I have an HP Pavilion g7-1260 with Ubuntu 13.10 on it. I would like to be able to use the wifi toggle key on the keyboard to enable and disable wifi. My wifi works fine and the light on the key turns on when I enable wifi through the Ubuntu networking menu. The problem is that pressing the key does not do anything. It should be activated when I press fn + f12. I tried using xev to see if an event was generated but there wasn't one. I also tried the same thing with apci_listen but it didn't output anything. Does anyone know how to get the key to work?

• How to install Radeon Open Source Driver?

  - by Clintonio

  I have an MSI Radeon HD 7850 card. MSI provide no Linux support, and the AMD driver gives me an Unsupported Hardware watermark that does not show up in screenshots. I uninstalled the proprietary driver and found that Unity 3D no longer works, and I really only picked Ubuntu because of the excellent shortcuts provided in the recent versions. Trying to locate the open source driver has been a pain for me. According to the documentation I have read it is pre-included in Ubuntu 12.04, yet there is no Unity 3D support. I tried using the newest drivers from AMD's website, but that also had the watermark. Does anyone know how I can get the open source driver? If not, does anyone know how to remove the watermark. I'm on the verge of going back to Windows.

• Why won't my install on Macbook work?

  - by Wyatt

  I am trying to install Ubuntu 12.04 on my Macbook. The CD drive is broken, so I am going from a USB flash drive I created. I can get it to "Try Ubuntu" perfectly fine, as a matter of fact I'm using it right now. However, I really want to install. Everything is partitioned, rEFIt is installed. I run the installer and I follow the guide at Apple Intel Installation I get to the install part of the installer, and after running it ends with a fatal grub error. Anyone know how to get past this? I feel like it has something to do with the fact that I don't get the last dialog box of the installer with the "advanced" tab used in the guide. Any help is greatly appreciated!

• Setup shortcut keys not working

  - by Tim

  In my Ubuntu 12.04, in keyboard settings, I didn't find a shortcut key for restarting X, so in "Customer Shorcut", I set up Ctrl+Alt+Backspace for command sudo restart lightdm. But after that the shortcut doesn't work. Is it because it requires root privilege? Also I have a SysRq key on my keyboard, which I think to be the "Magic SysReq Key". My SysRq key is shared with PrtSc key (for screen shoot), and is in blue which means I have to press Fn key at the same time to invoke SysRq instead of PrtSC. But every time I press Fn+SysRq, it always shoots a photo of the screen, same as just hitting PrtSc i.e. without hitting Fn. I wonder how to use the Magic SysReq Key? Does it mean the shortcut has not been linked to any command that is supposed for Magic SysReq Key yet? PS: My laptop is Lenovo T400 and OS is Ubuntu 12.04. Thanks!

• GUI Application Resolution from Text Mode OS

  - by brettw

  I'm trying to turn a computer into a Linux thin client via Ubuntu. I have a Dell OptiPlex 755 loaded with Ubuntu 14.04 installed and fully patched. I've configured the OS to run in text mode and automatically launch the VMWare Horizon's client, which works. The issue is that when the Horizon client launches, its resolution is only 1/4 of the screen. I've played with the resolution settings in grub which appears to modify the text environment but not the application environment for Horizon's. Can someone point me in the right direction on how to increase the resolution for a GUI application launch from text mode so it's full screen. Thanks!

• Logitech G700 mouse scrollwheel is way too sensitive, how can I configure it?

  - by Snir Hassidim

  I am trying to migrate my brother to use Ubuntu. However, his Logitech G700 mouse's scroll wheel is extremely sensitive. By sensitive, I mean that, due to the fact that it uses high-resolution scrolling, every minor nudge is interpreted as a scroll attempt. I have no way to configure this in Ubuntu - I want the OS to ignore every few events from the mouse scroll wheel to make it work properly. xev in a terminal is going crazy whenever I even lay a finger on the scroll wheel. How can I fix this issue?

• How do I control remote Windows 7 machine? VNC/RDP/?

  - by artfulrobot

  I have a Windows 7 laptop that's going out and about and I'd like to be able to admin' it from my Ubuntu (precise) desktop. While the laptop is in my office I can use Gnome's "Remote Desktop Viewer" (Vinagre) to connect via RDP. However, when it's in the office I don't really need RDP of course! And when it's out of the office I cannot control the routers/firewalls along the way, so I won't know the IP and cannot set up port forwards. I'm looking for a Ubuntu compatible way to achieve this. Nb. I can set up port forwards at the my office end, so a service on the laptop could try a "backwards" connection to my client.

• Where did all of the options go? [closed]

  - by Devan

  In the last version of Ubuntu I used (10.04) I had the following options, which I can not find on 11.10: Set amount of time before screen dims Show percent instead of time in battery icon Change/add screensaver Change default applications (especially in the new launcher) Also, is there any way to make it so unity opens to more apps/all instead of the current default? Basically I just need to know if there's any way to customize Ubuntu that little bit more. Any help with any of the options above would be greatly appreciated! Note: I'm a noob and don't know much about command line, so gui apps would be preferred, if possible.

• Suggestions about php editors and file sync programs

  - by Deus Deceit

  I'm working with ubuntu and lately I decided to learn php. I have everything setup and I'm currently using aptana 3 as my php editor and for file sync. It seems like the process for file sync is too much, it has to check all files just to upload 1 file. So if someone can tell me how to update a file at once without delay, that's welcomed. I find aptana not being what I like. It's a good editor, but I would like to know if there are alternatives out there. Can someone suggest a good php editor for ubuntu?

• Why does starting a program log me out?

  - by Bruce McKean

  I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause? I'm interested in learning more about the Linux system. How to correct any future problems like this? Computer Specification: Processor : 8x Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz Memory : 8155MB (1092MB used) Operating System : Ubuntu 12.04 LTS Graphics Card : GeForce GT 520/PCIe/SSE2

• How can I force the (re)discovery of PulseAudio network sound devices?

  - by Christian

  I'm using the PulseAudio feature of network sound devices (not Multicast/RTP) to play sound from my netbook on the audio equipment connected to the HTPC when at home. This creates a virtual sound device that I can then use instead of the physical built-in one. Most of the time this works just fine. Sometimes however, the virtual sound device just doesn't appear. Disconnecting from and reconnecting to the network helps sometimes but not always and it's annoying and potentially bad for existing TCP connections. So my question basically is: Is there some way to tell PulseAudio "Hey, just look again if you really can't find a network sound device."? Edit: Unloading and reloading the module-zeroconf-discover with pacmd does not help either and it doesn't appear to be an avahi problem per se since avahi-browse -t --all | grep PulseAudio shows lots of right-looking stuff, even when the devices aren't listed in pavucontrol or pacmd list-sinks. Edit 2: I'm using Ubuntu 12.04 on both boxes for all the difference it might make.

• Lubuntu wireless issue with Broadcom chipset

  - by Variant Web Solutions

  I'm a web dev that just started a new venture in buying wiped laptops in bulk and selling them at a low cost to lower income families that want a laptop that will simply preform and not become virus ridden and require constant maintenance, so naturally I opted for a linux distro and after some research, lubuntu was my top pick. I'm not a stranger to linux as all of my servers for my web dev business are linux, but I am however new to L/Ubuntu and I'm having some issues with both wifi (broadcom chipsets) on the 20 or so dells that I have right now, D800's, D810's and E5400's. Not sure if you can point me in a solid direction, I've scoured (and implemented) the suggestions on ask ubuntu and still coming up short.

• Ati Radeon HD 5850 + two screens with different resolutions

  - by Nikolas

  How can I use these screens like I would use in Windows? When I turn off "copy" it gives me an error. I have tried community drivers and AMD drivers but both fail at this task. I use Ubuntu 12.04 with latest updates. It did not work in Ubuntu 11.10 either. I use DVI to connect my PC to my monitor and HDMi to my TV. It is a Sony Bravia, bought in 2008. I can't remember the model. Also, this same problem occurs when I connect to two Full HD monitors, both DVI. I cannot turn of the cloning of screens. How do I turn it off? Windows can do that.
