• Can't edit/drag-and-drop widgets in QtCreator in Unity, Gnome3 - ok

  - by Maksim

  I have QtCreator 2.4.1 (Qt 4.7.4) installed on Ubuntu 12.04 LTS x86. When I try to change UI - drag-and-drop any widget (buttons, label, etc.) it won't let me do it, like it's read-only. The icon when I drag is a circle with a line through it. I've found that problem in Unity and it's suggested to install Gnome3 shell - Can't edit/drag-and-drop widgets in QtCreator I tried to install Gnome3 and it works fine as expected. But the question, is there any other way to work proper with QtCreator in Unity?

• VLC Ati Radeon 6870 Ubuntu 12.04 image skewed flicker

  - by Aaron

  I'm running Ubuntu 12.04 with ATI Radeon 6870 connected to my 40' Sharp TV. The video image is slightly jigged, like breaking a bit and slightly delayed. It just isn't smooth. The computer is very fast, like i7 with 12gb ram. I tried to run the same video with my mac laptop and on the tv with the same connection cable and it was running smoothly. i tried changing the video output in VLC to x11, increase caching, h264 skip loop filter to all, increase monitor refresh rate although it's already at 60 and it's an LCD tv. this is my xorg.conf : Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[3]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "0-DFP9" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-DFP10" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x1024" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "amdcccle-Device[3]-0" Driver "fglrx" Option "Monitor-DFP9" "0-DFP9" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Screen" Identifier "amdcccle-Screen[3]-0" Device "amdcccle-Device[3]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

• How do I keep track of modifications to a new server?

  - by eveo

  I purchased a server for the sole purpose of familiarizing myself with the CLI so I don't get royally screwed when I enter a real development environment. However, I have some questions. I've managed to SSH into my server, all is fine and dandy, installed LAMP too which went flawlessly. Now I'm wondering, the more changes I do, the more cluttered my server will become. Can I revert changes? I don't want to keep customizing things and installing things and just having a cluttered server overall. Where can I track changes to my system?

• Cisco Linksys AE2500 wireless adapter not working

  - by makuto

  I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

• Configuration of the network manager via DBus: how to set the ad hoc mode

  - by Andrea

  I have an hard nut to crack: a nice bottle of italian Chianti wine to the solver! :) To automatically configure Wifi, I first have to kill the network manager and than activate the wifi via the commandline: I do this all automatically in my application and works great. However... it is not the right way to do this. As the user has no network gui anymore to configure some other network access. A much better and transparent way would be to configure wifi directly via network manager over the DBus interface. I was able to configure it, but I wasn't able to set it to ad hoc mode... Searching the web for a while: a lot about configuration in general but nothing related to ad hoc mode. I think the only way to do figure that out is to look into the source code of the network manager...maybe someone already did it and he can answer.

How to save this permanently?

• Safety of installing Ubuntu alongside Windows

  - by giowck

  Is it really safe to chose the "Install Ubuntu alongside Windows" option from the Ubuntu installation program? I never used that option, instead I used other tools such as partition magic or windows 7's disk tool to resize my partitions. Since I'm going to install Ubuntu across a lot windows (XP, Vista and 7) machines. It would not be nice to damage those Windows partitions. What is your experience? Can I use this feature without concerns?

• Changes to 'resolveconf' discarded when connecting to a new network

  - by sudheer

  I have upgraded to 12.10 from 12.04 recently and I am having issues with connecting to the Internet. I got an IP address and am able to ping other LAN IPs in the local network but I am unable to connect to the Internet and am even unable to ping www.google.com from a terminal. Somehow making changes in /etc/resolv.conf and restarting resolvconf service and rebooting works but I need to do this every time I connect to a new network. How do I make these changes permanent? Can someone suggest a solution to this issue?

• 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.

• Ubuntu 12.04 host – Virtualbox 4.1.12 Guest=Windows 7 – Network will not connect

  - by user287529

  Ubuntu 12.04 host – Virtualbox 4.1.12 Guest=Windows 7 – Network will not connect. I'm using Ubuntu 12.04 on an Acer Aspire 5742-7645 laptop with 4GB memory, Intel Core i3 processor, Intel HD Graphics, DVD drive, 802.1 b/g/n, and 500 GB HD. I connect to my router via a wireless connection. I have installed Virutalbox 4.1.12 from the Ubuntu Software Center and installed Guest additions 4.1.12 in the Windows 7 guest session. I have Windows XP and Windows 7 installed as guests in Virtual box The network settings are different for XP and 7 – see below. Network Settings XP guest = Adapter 1: PCnet-FAST III (NAT) - Network works perfectly and has worked well for several years. Network Settings Win 7 = Adapter 1: Intel PRO/1000 MT Desktop (Bridged adapter, eth1) Promiscuous Mode = allow all Cable connected = checked When I originally installed Windows 7, I tried NAT and the guest network would not connect. Once I changed the setting to the above (Bridged) the Network worked perfectly. However, what I believe is after updates (not sure if it was an Ubuntu or Windows update) the guest network stopped working and I can not get it to connect.

• Lexmark E240 printing issues

  - by NoamH

  I have Lexmark E240 laser printer. I have been using it with 12.04 (32bit) for 2 years with no significant issues. Since lexmark does not support this printer on linux, I used alternatives drivers that were suggested by the community, such as HP-lasterjet, E238, generic PS, etc. They all worked fine, more or less. After upgrading to 14.04 (64bit fresh install) I tried to configure the printer as before, but now I have problems. The test page is ok, but when printing, most of the times, the first page in the document will be printed very partially and in 300% zoom. Next page might be ok. If I turn off the printer and back on, the first page might be ok, but in the next print job, it will be broken again. I used all the above printer options. Same results. I did NOT install the lexmark drivers since they are intended for 12.04 and the package manager report that it is in "bad quality" (don't know why). Does anyone has any experience with this printer in 14.04 64bit ?

• ubuntu 14 painfully slow on dell r200

  - by sirmonkey

  I didn't notice it at first. The machines (there is 20 plus) are to be used a simple file servers. It wasn't until samba just wouldn't act right that I installed a desktop gui and started more diagnoseing the problem did I catch the slow preformance... I've tested 4 servers they all suck. And windows 7 runs fantastic on them. I have Google and searched. But nothing to explain this. The easy test is dmesg is so slow you can almost read it. I'm guessing it's an apic or cpu power management issue. What output would you all like????? It is a core2 machine with 4Gb of ram. On board data.

• System freezes while not in use, how do I fix this?

  - by PHLAK

  Bare with me, the following is a bit winded. I have Ubuntu 10.10 Desktop 64-bit installed on my laptop and up until a few weeks ago it has been running great. Then one day, while I was not using the laptop it froze. I was logged in as my user but had locked the screen locked and closed the lid. I didn't notice that it had frozen until I opened the lid and wiggled the mouse to try and log in. The screen remained black and I got no response. I immediately tried Alt + F2, F3, F4, etc. but got no response. The only thing I could do was hold the power button to power off the machine. The freezing has happened as quickly as within 10-20 minutes of the system being logged off and lid closed and as long as 4-6 hours. My machine is NOT configured to go into standby when plugged in and this has happened both on AC power and battery. Troubleshooting I have performed: I uninstalled programs I knew that I had installed between when it was working fine and having problems. Those programs were CrashPlan, Shutter and Conky. After uninstalling ALL of these programs the freezing still occurs. Next, I decided to SSH into the machine from my desktop and leave an htop and tail of the syslog running. Here are screenshots of the last thing shown on both when the system froze: htop, syslog Here is a dump of my syslog after another freeze. The freeze happened at 9:14 and I didn't notice it until about 10 minutes later and rebooted, hence the 10 minute gap from 9:14 to 9:24. In the above syslog dump I noticed a lot of NVRM: os_raise_smp_barrier(), invalid context! and upon investigating that message learned it was from the proprietary Nvidia driver I had installed. Thinking this could be part of the problem I uninstalled the Nvidia driver and reverted to using the Nouveau driver. The computer still froze after a few hours. Lastly, thinking the problem could be caused by overheating I used compressed air to blow out any dust in the CPU vents and all other openings on the laptop. None of the above troubleshooting has helped and the freezing still occurs. What other steps can I take to troubleshoot and/or fix this problem? Note: Yesterday X started to eat up a lot of CPU power and eventually froze my system while I was forwarding an X session over SSH (from another PC to my laptop). I'm unsure if this is related or not as it doesn't match any of the symptoms of the problem above. Aside from this, the system has never frozen while in use, even under heavy load. EDIT: I just ran Memtest86+ and it made it through two passes without any errors. Just eliminating possible causes here.

• Installing drivers for an ATI 6950 in Ubuntu

  - by aj.esler

  Is there any way to get ubuntu to recognise an ATI 6950? I have tried installing the proprietary ATI drivers, but these do not seem to work properly. It seems to screw up the gnome desktop, and starts booting into terminal. I'm somewhat of a linux newbie, so not really sure whats going wrong. I don't want to game on ubuntu, I just want it to recognise my dual monitor setup rather than mirroring the monitors, so any driver that does this is fine by me. It seems like the open source ATI radeon drivers will not support the 6950/6970 for some time, at least until kernel 2.6.38 is released. The card is also flashed with the 6970 firmware, not sure if this is important. I am running a 64 bit version of ubuntu, I installed ubuntu server 10.10, then installed gnome-desktop.

• Windows Error After Wubi Install

  - by user106563

  The initial install on my laptop was Windows 7. I installed Wubi on Sunday - the install seemed fine. I was able to log in and use both Ubuntu and Windows. On Monday I started receiving the following error in Windows: windows cannot access the specified device path or file This occurs on every link I click on - essentially rendering Windows unusable. I do not experience the same problem when Windows is started up in safe mode. I have tried numerous virus scans (Malware bytes, Avg, AdAware) and have removed various trojans etc. Windows is still unusable. Ubuntu seems fine so far. My question is, can this error be attributed to the Wubi install?
