• Frequent GUI pauses in Ubuntu 13.04 / Unity / Intel HD4000

  - by Simon

  I'm experiencing very frequent (and regular) GUI pauses on my system. Every 30 seconds (pretty much exactly) the GUI will freeze for maybe .25 to .5 seconds. The mouse stops moving, keys stop echoing and a stopwatch timer briefly pauses. I'm using the Intel Graphics driver available from: https://download.01.org/gfx/ubuntu/13.04/main I've looked in a few places and tried a few things for a solution: I've checked cron and anacron for scheduled processes. I've disabled background processes (eg mysql, postgres, apache) not that these were doing anything anyway I've checked the following posts and tried the suggestions there: Unity GUI pauses/freezes for less than a few seconds How to go about troubleshooting frequent system pauses I've watched the system using top and System Monitor and there are no spikes (or even blips) of cpu usage when the pauses occur. There are no obvious error messages in dmesg or syslog There is loads of free RAM (8GB+) and no swap usage If it helps it's a ZooStorm i5 laptop with a HD4000 GPU, 16GB Ram and an SSD. Any help / suggestions would be very gratefully received.

• Ubuntu 12.04 resolution issue ATI radeon x1600

  - by JP Hellemons

  I have a brand new Ubuntu 12.04 installation, but my resolution is set to 800*600 4:3 and my resolution using windows xp is 1440*900 but that option is unavailable for me. When I search for restricted drivers, there are none. So I searched the ati website and downloaded a .run file of about 80 mb. but that gave me an error when I tried to open it. I downloaded some fglrx thing from the repositories and now there are some widescreen options available but still no 1440*900 there is some ATI controlpanel installed, but when I try to open it, it fails telling me that there is now suitable driver. ps. my video card is a 512MB ATI Radeon Sapphire X1600 AGP

• Setting up ubuntu as a wireless accesspoint

  - by nixnotwin

  I have an android phone which doesn't connect to ad-hoc networks. I use ad-hoc network to share internet among my pcs. I want to setup my ubuntu laptop as a wireless access point. But I don't want my ubuntu laptop to be a router as described here as I'll be using suid3 as a http proxy. It should be just a wireless accesspoint which broadcasts it's SSID like a home wireless router. The ubuntu laptop has athros wireless card which requires athk9 driver.

• Installing wireless drivers without internet access [closed]

  - by Lucas Jones

  Possible Duplicate: How can I install and download drivers without internet? (This is related to my other question; my approach there didn't work.) My friend has (I'm quite sure) a Broadcom wireless chipset. However, he doesn't have any wired internet access on the machine, so his only option is to boot into Windows (he is using Wubi) and download packages there. This means we can't use the Hardware Drivers dialog to install the drivers. He can't fetch the repository information, so the Broadcom driver packages aren't showing up in Synaptic. Is there any way to get Wi-Fi working?

• Which Large File System Format to use for USB Flash drive compatible with Ubuntu/Mac/Windows?

  - by wajiw

  I've had this problem for a long time and can't find a solution. I switch between the 3 OSes all the time and use a 1TB USB Drive to do so. I can't seem to find a format that is compatible across all systems that handles large files (at least 8-9 GB). Does anyone have a solution for this? Recently I've tried exFat but that messes up the filesystem when trying to read on windows after adding files from Ubuntu (using the fuse driver). The OSes currently I'm using are Windows Vista/7, Mac OS X (10.6.5) and Ubuntu 10.10

• Cursor freezes for 5 secs every now and then

  - by user20560

  I've installed Ubuntu 11.04 (64bit) on my new Thinkpad Edge 11 laptop from Lenovo with the following specs: Processor type AMD Athlon II Neo Processor Speed 1.8 GHz Memory Type DDR3 SDRAM RAM 2048 MB Hard Drive Type HDD Harddisk 250 GB Grafic processor ATI Mobility Radeon HD 6310 Ubuntu has found all my hardware and it works perfectly. I have one irritating problem though: From time to time (sometimes every minute, other times every hour)the cursor freezes for about 5 sec. This happens independently from the number of processes running on the laptop. It's only the cursor that freezes - I can still tab between windows and use the keyboard. I've installed GPointingDeviceSettings, activating the trackpoint, which btw works perfectly. Also I have installed the ATI Catalyst proprietary display driver. Anyone has an idea of whats wrong? Thank you in advance Best regards, Jens

• Ubuntu boot is slower than Windows 7

  - by Alex Bixel

  One of the reasons I installed Ubuntu (Wubi installer) was for a supposedly quick boot time. My boot time with Windows 7 is about 20-25 seconds, while my boot with Ubuntu is 30-40. I judged the boot times from the time after I selected the operating system on the initial selection menu and the grub menu, respectively. This is even after following all sorts of online guides to improve it. I've done driver profiling (and yes, I remembered to remove the "profile" edit in the grub file afterwards), I've cut a fair few startup programs out, and I've installed the preload package. But I'm still getting startup rates phenomenally slower than Windows 7. Any help here?

• Ubuntu 12.04 Touchscreen Calibration

  - by Lee

  I have a machine with Ubuntu 12.04 installed, with dual monitor, via VGA and DVI Interface. The monitor is one touch screen and the other one is regular LCD Monitor. The touch screen is made in China with some unknown brand, and I am using eGalax Driver. The touch screen is now detected and works, but i need to do some calibration since it does not correctly perform click on touch. The problem is, when I’m using xinput_calibrator, it shows 4 crosses to be clicked on, because I’m using dual monitor, the crosses is now show 2 on the touch screen (touchable) and the others on the other monitor which is regular non-touch monitor. Please help, thank you.

• Does 64-bit Ubuntu work on the Acer Aspire One D255

  - by hippietrail

  The Acer Aspire One D255 is the cheapest dual core netbook on the market right now. It has an Intel Atom N550 which should be able to run a 64-bit OS. But when I try to boot the Ubuntu 64-bit live CD I only get one line of diagnostic output that it "found something" on the USB CD drive before locking up. I haven't been able to find anything by Googling yet. Could it just be driver issues for this machine or could the platform be inherently frail for running 64-bit? (My machine is two days old on trial and Windows 7 and Ubuntu 32-bit run but it has locked up under casual use on both OSes.)

• No internet access since 12.04

  - by Roelof

  I have updated yesterday to Ubuntu 12.04 but can not access the Internet. It is an old PC without wireless. But the older Ubuntu I had installed up until now (11.??) worked perfectly. I'm not that familiar with Ubuntu, and I have been trying Google for some time know, but I cannot find the answer. I noticed that running nm-tool resulted in some things that don't sound right: Type: wired Driver: ne2k-pci state: unavailable Default: no Carrier: off Does anyone have a way to fix the connection?

• Wifi won't work without ethernet (Ubuntu 12.04)

  - by alok

  I have a strange problem. I am running Ubuntu 12.04 on a Dell Studio 1558 laptop. I'm usually unable to access Wifi (I have a BCM43224 wireless card with the STA proprietary driver installed.) So I have to unplug the ethernet cable from my Wifi router and stick it into my laptop's ethernet port to access the Internet. But when I stick the cable back into the Wifi router and try connecting to Wifi, Wifi inexplicably starts working. How can I get Wifi to work all the time without having to 'jumpstart' it with an ethernet connection?

• Installing drivers for an ATI 6950

  - 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.

• How to completely shutdown Ati card

  - by Celso

  I would like to know how do i prevent my Ati card from turning on when i enter on ubuntu 11.10. My bios only lets-me shutdown intel hd card or leave the both on but i want to know if is possbible to completely shutdown without having to access to the bios.( if is possible to turn of without using Vgaswitcheroo even better!) My system is: Acer 3820tg-- intel core i3 350M, 2.26 Ghz L3, Ati Mobility Radeon HD 5470 up to 2138 MB hyper memory, 13,3" HD LED LCD, 4gb DDR3, SSD corsair 60GB sata 2. EDIT: I now know what is missing on the answers! I edited /etc/rc.local file and added the next lines: Sleep 3 echo ON /sys/kernel/debug/vgaswitcheroo/switch echo IGD /sys/kernel/debug/vgaswitcheroo/switch echo OFF /sys/kernel/debug/vgaswitcheroo/switch And then save the file and restart. It should be possible to use only the intel card now. By the way, i didn't blacklisted the radeon driver because doing it make my ati card wake up. (use it at your own risk. i only tested in my system)

• Restoring windows path on Windows 7

  - by Renso

  Issue:You changed the windows path and made a mistake and now want to reset it.Solution:In short, you can't. If you restore to the system default, you will loose any paths that were appended when you or the manufacturer installed software and drivers. Each time you install some sort of software or driver, MS Office, Turbotax, etc., it creates/appends to the path so that it points to it's start-up program.Too late now, but you should create a restore point BEFORE you touch the windows path if you are not sure what you are doing:http://www.sevenforums.com/tutorials/700-system-restore.html http://www.sevenforums.com/tutorials/2083-system-repair-disc-create.html At a minimum you need the following:%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\AT worst you can reset it to the above, and go through each application as you use them and run into problems to fix the path. The REPAIR option when you select to change/uninstall a program can help with that.

• Stuck on busybox after a fresh install

  - by user54841

  I installed 11.10 and was getting stuck on Busybox unless I type exit. After grabbing the latest updates it then didn't get stuck on busybox but instead on a black screen of nothingness. I've now reformatted and started again using the exit technique for the time being. I had a search here before posting and none of the answers gave much insight, other than it 'could be a gfx card driver issue'. I'm using new hardware that has no issues with Mint, Win7 or WinXp. BUT note, I'm not dual booting, its a complete fresh install formatting the entire drive. Any help is appreciated as I'd really like to get stuck into Ubuntu. Thanks in advance. -Luke

• Cannot login via Unity login screen after upgrade to 12.04

  - by codesurgeon

  Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message - my user account and credential verification seem to be OK. I suppose that my individual graphics configuration causes problems ... I'm not sure how to reset that. I've tried stopping the UI via sudo service lightdm stop executed sudo nvidia-xconfig and restarted the UI sudo service lightdm start to no avail. My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07. Anybody have an idea how to get this fixed? Your help is appreciated :)

• Toshiba satellite L500 no Wifi anymore!

  - by Benjamin Piller

  I have a Toshiba Satellite L500 with Ubuntu 12.04 and its wifi suddenly stopped working!! I've never seen like that before.. I tried also using external USB wifis but no success. I am not able to turn it on with the function keys nor using rfkill commands and similar WLAN manipulator Commands in the terminal! It was working before for at least 4-5 months!! The computer says it's turned off by hardware. I checked it and the Driver is fine. So why can i not use any Wifi on my computer?? Why it is suddenly disabled? I checked the BIOS too there is enabled the WLAN. I spent 10 hours for searching for solutions but i am out of ideas!!! Please Help!

• How should I handle using two databases with a legacy PHP application?

  - by Toby Allen

  I have a legacy PHP application that was written in 2004 and uses MSSQL as a database backend. At this stage MSSQL is still supported by PHP but only just via a Microsoft driver. I have looked at converting to mysql via automated tools, which work quite well, but I have quite complex views which need a lot of individual work to convert. I don't have a great deal of time to do this. Many tools I wish to use and frameworks I would like to move the application to, don't support MSSQL, so I was considering adding new features using a new mysql database and wondered if anyone had opinions on the pros and cons of using two seperate database backends in a single application?

• Split screen and other issues on Ubuntu 11.10 with ATI graphics card

  - by garus

  Ever since updating my Ubuntu 11.04 to 11.10 I experience issues with graphics. The biggest is the "split screen" effect where my desktop is shifted to the right, resulting in having Unity bar in the middle of the screen. As shown here: http://i.imgur.com/I8nmZ.jpg This changes from boot to boot, sometimes it's on the left, sometimes in the middle. What I tried: Removing fglrx drivers completely Installing post-update version of them, but installation is broken ATM in the Ubuntu, so no go. No one is even trying to fix it (bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/873058 and a couple of duplicates out there) Also using the open source "radeon" driver results in the same (I have a better successful boot ratio with this one, proprietary rarely lets me boot) Other artifacts are: serious screen tearing weird lines flickering in random places lagginess Did anyone experience that? My specs: Ubuntu 11.10 AMD Radeon HD 6950 1GB
