• laptop screen goes blank after waking from sleep

  - by Tojo Chacko

  I have been facing this issue from the last week after some update. Whenever my laptop wakes up from suspend state it just shows me a blank screen. Regardless of whatever I do(move my mouse, press keyboard buttons) it just refuses to wake up. I am forced to do a restart and lose all my unsaved files. Has this issue been reported for Ubuntu 12.04? I am using a Lenovo X200 with Intel Mobile 4 Series Graphics Chipset. Please let me know if any body has found a fix for this.

• Ubuntu freezing after boot

  - by jbm1991

  I have ubuntu 12.04 LTS dual booting with windows 7 on my laptop without any problems and felt like doing the same on my desktop. However now that I have installed Ubuntu on the desktop through Wubi, if I boot into ubuntu the log in screen is as far as I get. I see my username and the password box but everything is completely unresponsive. I can move the mouse around the screen fine I just can't click on anything and the keyboard doesn't seem to work at all as I've tried a few shortcuts and there's no response at all. I have done a some searches and I think it's a driver issue but I don't know how to fix them as I'm pretty new to ubuntu and cannot log in at all. Desktop specs if needed: Intel core i7 2700k, NVidia GTX 580, 8GB RAM. Thanks in advance

• Kernel Panic while Installing Ubuntu 12.10 from USB Drive

  - by user100889

  Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

• Fan working non-stop on a Dell Inspiron 5110

  - by cankemik

  First of all i'm new at ubuntu. I've only tried 11.10 before 12.04. Since then my notebook's(Dell Insprion 5110) fan was working non-stop. And also battery lasts in 2 hours. So i made a research. Some said it's about graphics card driver. I've tried so many things, so many codes but i get no result. I must say that i've tried ironhide and bumblebee. non of them worked 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff)

• dual display breaks unity

  - by dougleduck

  I find that most of the time, when I plug in my Dell 19" monitor with an HDMI lead, unity can't decide on the configuration; it will switch between different resolutions, and setups every 2-30 setusecond until I either ctrl-alt-backspace or unity crashes so I have to hard boot. Alternatively all the windows decorations and unity get killed. My setup is 11.10 64 bit,Dell Vostro 3550, AMD Radeon HD 6630M 1GB, Intel Core i5-2520M processor 2.50 GHz with integrated graphics card Currently I don't think the Radeon graphics card is working properly, but I'm not sure.

• Why do my window titles lag behind the window contents?

  - by user8758

  The window title displayed in my maverick is often for the previous window. This is most noticeable in Firefox after using the back key to go to the previous window, but it also happens in file search and various media players. This even occurs in brand new installs of maverick and linux mint 10, so I know it has nothing to do with any configuration file snafu. I am using a Toshiba Satellite notebook with Intel graphics. Oddly enough, linux mint does not display this glitch when running in virtualbox (don't know about maverick in vbox). Any help with this issue would be greatly appreciated.

• Ubuntu slows down even after cpu-intensive process is ended

  - by Matt2

  After a Skype video call, or the use of virtualbox, Ubuntu slows down to a crawl, even after the process is ended. Running htop reveals that processes that used little CPU before are now all using about 30% cpu (namely Compiz, Firefox, Python, and Skype, but I'm sure there are others), to the point where all my cores are at 99%. All I can do from here is restart. Any idea why this is happpening? I'm running Ubuntu 12.04 64-bit on 3.7 GiB of memory, Intel® Core™ i3 CPU M 330 @ 2.13GHz × 4, VESA: M92 graphics driver. Not sure why I'm running VESA, I installed fglrx, but I suppose that's a different question. Thanks in advance!

• How do I check whether partitions on my SSD are properly aligned?

  - by elementz

  I just installed ubuntu on my new intel SSD. Now I am not sure, whether paritions are properly aligned in respect to my specific SSD. Here's my fdisk output. $ fdisk -l Platte /dev/sda: 120.0 GByte, 120034123776 Byte 255 Köpfe, 63 Sektoren/Spur, 14593 Zylinder Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000a6294 Gerät boot.

If it is the case, that my partitions are not properly aligned, what could I do to fix this without having to reinstall everything?

  - by daveu1

  I have a new Samsung RV520 and have just installed Precise Pangolin 12.04 LTS. I am having serious problems now with the wifi constantly disconnecting.

I am using a Intel Centrino N wireless card. Please can anyone provide any guidance as to how to resolve these issue on this machine. Many thanks for your help.

• Can I get some advice on graphics cards please?

  - by Victor9098

  I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

• Bad sound quality and headphones not working

  - by wifi

  Using Ubuntu 10.10, on a HP Pavilion t3019.es, which has a Realtek ALC880 soundcard. It has 6 rear jack outputs, plus digital audio input and output, plus 3 front jacks (mic, headphones and a blue one which i don't know what's for). The sound on my computer is very low, and when i raise the volume up to 50%, it starts sounding distorted, crackling. Also, the headphones don't work when i plug them (it just keeps on playing through the speakers). I tried to comment the "/etc/modprobe.d/alsa-base.conf" file according to the soundcard and jacks in my computer, but none of the lines added worked (naturally, didn't added them at once). I found out that adding "options snd-hda-intel model=generic" to it made the sound better, but it's not as good as in Windows yet. Any ideas? Other than setting the PCM value, didn't work for me. Thanks.

  I have an Acer monitor and an Intel Pentium 4 running 12.04 32-bit. Chrome renders all webpages like this: This is how CNN should look: I have Firefox installed and its images/fonts look fine.

Thanks in advance.

• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• Very slow startup after update to 12.04

  - by M Legoh

  My hardware: Dell Latitude D600 laptop Processor: Intel Pentium (r) 1.8 GHz Memory 1.2 GiB Graphics R200 (RV250 4C66) x86/MMX/SSE2 TCL DRI2 Disk: 37.7 gb I did an update from 11.?? using the automatic system update that pops up when you switch/log on. Ever since then when I switch on the machine it takes approximately one hour to get to the login screen. Sometimes the actual login will take time too, but sometimes within a couple of minutes I am logged in. Once I am logged in I find I can work normally, the response is not swift, but is neither too slow that I cannot work. I was wondering if there was anything I could do to speed things up. I deliberately did not do a clean install from disk, because I did not want to loose settings on the machine.

• 3TB non-boot hard disk on older motherboard

  - by Bcos

  It is time to expand the capacity of my Ubuntu home file server so I would like to purchase some 3TB hard disks. However, I am concerned with potential compatibility issues. I've tried searching around but I haven't found information which clearly addresses my particular situation. My server is running Ubuntu 10.04 on an Intel P35 chipset based system. The motherboard does not support UEFI (and, by extension, GPT?). However, Ubuntu does support 2TB disks. Will I be able to properly utilize these new disks, or does the motherboard limitation trump all else? The boot disk is <2TB and will not be updated nor am I dual-booting; these disks will be used strictly as slaves in a pure Ubuntu environment. I'd hate to pull the trigger on these new disks just to be unpleasantly surprised, so any feedback is appreciated. Thanks!

• No Sound via HDMI

  - by Goony Hill

  I have ubuntu installed on a Acer aspire revo 3700 intel atom processor with nvidia ion graphics this is plugged into a celcus 32 inch TV via HDMI (1080p). The video driver shows as an nvidia which I can select. I have set the sound to play via HDMI and the output to HDMI but get no sound. I have tried a sony 1080i TV with the box but get eratic results with the graphics, but the sound picks up straight away that is there is no need to select it. The graphics on the celcus TV work but I get a dialog box showing loads of different resolutions and frequencies which I have to close manually, these appear to be attempts to set different resolutions for the TV. Am I missing some sort of screen/sound driver, if so does anyone know what might support the celcus 32 inch (1080p) tv?

• Ubuntu 10.04 LTS Minimal requirements (special)

  - by BDX

  I have a PC with 512MB of RAM, an Intel Pentium 4 processor(2GHz), SiS 651 video card(32MB) and a SiS C-Media AC'97 sound controller. I know that my video card is not and will not be supported for Linux. But I wonder if my PC is able to install and start Ubuntu, not just 10.04 LTS, because I'm willing to download 12.04 LTS when it's released. Will unity work? I searched on the internet but I couldn't find a good answer. Thanks in advanced.

• Compiz cube issues since upgrading to 12.10. The caps and 3d windows are all over the place.

  - by Slarty

  I think it's due to residual settings from the old reflection and deformation plug in. I've attempted a complete reset of the settings and still no go though. The cube caps stay black and glitch out when I spin it etc and I see multiple copies of each window. It's like it's trying to display the "inside the cube" setting and the regular just floating 3d window at the same time. Here's one example (rep isn't high enough yet for fancy img imbed, sorry) http://i.stack.imgur.com/rrbBd.jpg Any ideas? I'm trying this on my desktop which is using an NVIDIA 8800 GTS card. I also tried it on an older laptop that uses an intel card and same deal. I think maybe I can use the dconftool and try to see if there are still settings from the deformation and reflection plug in causing this. Unless someone knows how to get that back (either a beta or an old version) somehow?

  I have a Dell D610 - Intel graphics - 1 Gig RAM. I have test the hard drive and RAM and both are fine. When I open Software Center, then Dash home my system locks up. The mouse cursor moves but is unresponsive if I try to right or left click anything. The keyboard is totally unresponsive and I have to hold the power button to power off! I have reinstalled from CD, did all updates but the issue persists. I tried using the track pad only, and I plugged in an external mouse also but no change. Everything else works great !
